I cannot recommend the team at GreenShield Insulation and the owner, Ahmad, highly enough. Unlike several other contractors who either quoted me over the phone or barely looked into the attic, Ahmad personally came to my home, thoroughly inspected the damage caused by rodents, and provided a very fair and honest estimate. This project was unusually complex and took nearly four months to complete. The process involved rodent exclusion, removal of decades of accumulated insulation, asbestos abatement, attic sanitization, installation of new ductwork, and finally new insulation. Throughout every stage, Ahmad remained involved, checking in regularly and making sure everything was progressing. A special thank you to Dave and Eddie, who removed the old insulation and installed the new material. What appeared to be a straightforward job of insulation removal, turned out to involve three layers of different insulation materials dating back to the 1950s. Despite the unexpected workload and physical demands, they never complained. They remained cheerful, professional, respectful, and hardworking throughout the entire process. As a senior citizen who carefully researches major home repairs, I greatly appreciated Ahmad's patience in answering my many questions. He was consistently kind, knowledgeable, honest, and professional. Unfortunately, not every contractor I met during this project demonstrated those qualities. The entire GreenShield team exceeded my expectations. Their workmanship, integrity, communication, and customer service were outstanding. I would not hesitate to hire them again and highly recommend them to anyone needing attic insulation, rodent damage restoration, or related services. read more

As a first-time homeowner, I have a lot to learn, but I knew for sure that our house was abnormally hot in the summer and freezing in the winter. When the team came out to inspect, they were incredibly kind and understanding. They thoroughly explained their recommendations and patiently broke down why batting insulation wasn't the right fit for our home. They also offered wall insulation which was what we were also looking for as our south facing walls always felt warm to the touch in the summer. We ended up hiring them, and they completed the entire job in just a few hours. I wanted to wait a few weeks before writing this, and I can now confidently say they did a fantastic job! The house feels significantly cooler and much less humid. (Keep in mind we had zero insulation before, so results might vary if you already have some old insulation). We'll see how it holds up this winter, but for now, I highly recommend them. To top it off, they gave us the most affordable quote by far--and it included the wall insulation, whereas other companies charged more just for the attic! read more

Great service! The owner came out himself to do the work with the team to help meet service needs. Great communication and went as expected.

I had my attic insulation replaced and got my interior/exterior walls insulated with Greenshield. Abbas gave me a good quote and clearly explained the process and what I could expect. His crew was professional, respectful, and competent. They got the job done in the expected time. No complaints, would wholeheartedly recommend Greenshield. read more

Greenshield has been great. They were very easy to schedule attic insulation for my house. The price was very reasonable, and the installers were very professional in how they conducted themselves in my house. I really appreciated that. I ended up hiring them again months later to do our exterior and interior walls for sound deadening. They did a great job with that project as well. My heating bill has dropped dramatically. I wish I had done this years ago. I highly recommend Ahmad and his crew. read more

Excellent communication and quality of work. Initially the quote was higher but owner negotiated it very competitive and for both attic and walls. The technicians were proficient with job as well as safety of house. I would definitely recommend them. They are Bayren rebate certified. read more

Greenshield Insulation - After - Insulation Installation Near Me - Santa Clara, California

Used their attic insulation replacement service this past week. They gave me a very competitive quote and came within a week. In 2 days, I was able to get my old insulation (along with all my friends that lived upstairs away) and day 2 came and blow in new insulation. 1st day took ~5 hours while 2nd day was ~3. Overall great experience and would recommend read more

Owner Ahmad was a pleasure to work with for our attic and wall insulation job. Competitive pricing and Ahmad was responsive through completion of the job. The crew that came for the job were super friendly, polite and accommodating as I was working from home that day. The process for setting up the rebate was straightforward and clear. Really appreciate their work and already noticed the difference this summer. read more

So clutch! I am thoroughly happy I chose to work Ahmad and Greenshield Insulation. They were knowledgeable, scheduling work was very fast and easy, their appointment window availability was awesome, and their pricing was solid! Long story short, I'm a real estate agent and preparing to list a property. The owner of the home mentioned the energy bill was insane during the colder months to heat the place and we realized the attic space insulation was basically just powder. We're on a TIGHT schedule to update the home before listing - a schedule that involves a major holiday right in the middle of it. The team came through the day before the holiday - right on time, friendly, and very mindful and considerate of the people at home and the property. They completed the work quickly and left the place like they were never even there. Most of all, I love that they offered me a chance to take a look at the finished work myself. You have to understand - I'm writing this not just because I'm happy with the experience and work, but because whenever I contract work on behalf of a client of mine, I'm staking my reputation as a real estate agent who can deliver. If something goes wrong, it's on ME and all my clients see is a straight line from the quality of work from my contractors to the quality of agent I am. That's something I have to take very seriously in this industry. Ahmad and the team not only had my buy-in that they could do the job, they made me feel like my reputation and my client's property were in great hands. Then they proved it. Greenshield Insulation is now my go-to for insulation work! read more

tldr - Don't hire Greenshield if you have a whole house fan. We just finished having Greenshield remove our old insulation, air seal, sanitize, and install new blown in insulation. We talked with 3 companies, and Greenshield had the best price and best communication up front. They were the only one participating in the rebate programs. We rely on a whole house fan to cool our house at night. It pulls in air from open windows, pushes air from our living space into the attic and out the eve vents. Before we did the project I was worried that the vents could get blocked, so I called Ahmad and asked. He indicated there wont be any impact on the fan. He was wrong, our fans have lost most of their flow rate. Ahmad denied they did anything wrong and wouldn't help fix it, and only offered me $250. It's going to cost a lot more to fix this. The inspector that came for the rebate, says he sees this all the time. So either I have bad luck, or Ahmad is being dishonest. As part of the air sealing they patched a hole in my utility closet, but the workmanship was poor. The guy forgot his dry wall and his ladder, and used my ladder and dry wall. It looks terrible, but it's in my utility closet, so no one will see it. But the insulation does work very well, and has kept our house very cool during the recent heat wave. Despite my disappointment with the house fans, this was the main reason we hired them, and on this main aspect, they delivered. As for the rest of the air sealing, we did have a few spots where their expanding foam was visible from around light fixture in my home. It was easy to trim away, not a big deal. Communication was always quick, and wen't very smoothly for most of the job. The rebate process has been smooth so far, looking forward to getting a grand back. read more

Reached out in order to get some blow in insulation for my kids rooms. Ahmad was super responsive, extremely friendly and gave a very competitive bid. The team that did the work came on time and was friendly. Couldn't recommend them enough. Thanks Ahmad! read more

We worked with Ahmad for our attic and crawlspace insulation. He was very thorough in his pre inspection and had competitive pricing. Several months later we are seeing a massive difference in our home comfort in the winter. Our heat bills have dropped by over 30%. We were able to get through a couple of days of power outage without the temperature dropping to very uncomfortable levels. We got the rebate he had promised as well. Already recommended him to my friends and one of them also completed a job with him and are equally happy. read more

I just had insulation out in approx. 1 month ago, and my home now stays a steady 66 with barely any use of new heater...guestimate 25% less use of Gas. Crew was very professional. Owner promised a rebate, and he delivered! Just got in the mail today. The inspector he contracts with is very professional, David Loperena and worked with PG&E and their Vendor Bayren. Highly recommend this crew! read more

I recently hired them to insulate the attic and some walls in my home, and I am impressed with their work. From the initial consultation to the completion of the project, their team was professional, knowledgeable, and courteous. They took the time to explain the different types of insulation and helped me choose the best option for my needs and budget. The team arrived on time, and the installation process was smooth and efficient. I took one star off because I needed to spend quite a bit of time cleaning up the blown-away insulation fabric from the holes in the walls. It would be perfect if they found a way to prevent the insulation fabric from blowing away from the insert tube. Since the installation, I have noticed a significant improvement in the temperature and air quality of my home. I am also pleased to see a reduction in my energy bills. I highly recommend them to anyone in need of insulation services. read more

Very professional, fast, and very competitive price. Greenshield will make sure (guaranteed) that you will get all available rebates. Greenshield workman (very courteous)) cleaned up perfectly after the insulation was complete. I highly recommend this company. Greg P read more

We learned about Green Shield through the PG&E BayRen rebate program. Green Shield is one of the vetted contractors in the program. We chose them because of all the great reviews here on Yelp. And the reviews are right --they were terrific and I highly recommend them, so I'm adding my own 5 star review! First of all, they quoted me half the price of of two other "attic" companies that I had called before I knew about the BayRen program. Seriously, don't go with those "attic" companies, you will be ripped off! Half of Green Shield's price was refunded to me by the rebate!! So in the end, instead of paying one of those "attic" companies $12k to insulate my entire house, I paid $3k with Green Shield after the rebate for the same exact work! Think about that -- using Green Shield saved me 3/4 off the "attic" companies' prices!!!! Anyway, they were very pleasant to work with. Ahmad was very communicative, and his insulation installers Parker and Dave were also very pleasant, professional, and efficient. They did the job in a half day, blowing insulation into the upstairs and downstairs attics of my house, and all of the exterior-facing walls (including the closets). They spackled all of the wall holes, but of course afterwards I had a painter come out to smooth it out and paint those walls. A few weeks after the job, an inspector from the BayRen program came out. A few weeks later we learned that we passed inspection, no problem. And a few weeks after that, we received our rebate check. Easy Peasy! Green Shield took care of all the paperwork, which was amazing! It was a messy process, having to move stuff away from walls and empty out some of our closets, but it was totally worth it! My house is so much more comfortable now. One thing I will mention -- if your house was built before 1980, have an electrician come out to inspect for knob-and-tube wiring. We had no idea that the downstairs of our house had knob-and-tube (the upstairs didn't so we assumed....). Green Shield won't insulate a house with knob-and-tube unless it is inspected and signed-off by a licensed electrician. Fortunately, our house was OK in this respect. The electrician told us that many houses in California used knob-and-tube into the 1970s. So if you're not sure, have an electrician come out first to inspect!!!! read more

Ahmad was referred to me by Elem3nts who did our energy audit. Between getting GREAT advice from both Alfredo (Elem3nts) and Ahmad re insulation, we are getting some amazing work done. Fixing our house before spending on BIG HVAC upgrades or Solar (those will still be needed, but smaller systems and saving energy over many years). Ahmad came in, assessed what we need, provided a competitive quote and also explained how city and utility rebates work. Long story short, after rebates, for less than $1000, I will get half my exterior walls insulated (the other half were done in a remodel a few years ago). And for less than $1000 I will get my attic insulation upgraded from R38-R49. And also Ahmad will air seal my crawl space. read more

I've worked with Greenshield twice. Ahmad is very easy to schedule with and his estimates are competitive. The crew is professional, shows up on time, does a thorough job, and cleans up after themselves. Whenever I have future insulation needs, I'm only calling Greenshield! read more

Background Story: I was working in my garage replacing the sheetrock when I reached inside the wall cavity and discovered......NOTHING!?! Where's the insulation, to my disbelief the house I had just bought had no insulation at all in any of the walls. Tearing out the entire sheetrock throughout the house would be very costly, but that is when I heard about blown in insulation into the walls. Blowing in insualtion to the attic is pretty easy, but ripping apart your walls and blowing it into your wall cavity, well that's no picnic. You can try to do it yourself and Home Depot will even give you a machine for 24 hours to use, but after further research I found out that the machine they give you will not dense pack your cellulose insulation, it simply does not have enough pressure so the insulation will settle over time. Greenshield to the Rescue: After getting several quotes, Ahmad from Greensheild was able to beat out their competitors on pricing. He also assured me his guys would not cut corners and they would dense pack everything and also seal the wall holes and patch once they are done. When his guys arrived I told them my fears about rushing through this project as I really want each wall dense packed. The installer told me he has been doing this for 15 years and even has his own custom built tools for dense packing, he showed me exactly what he was doing. When he finished the first wall, he showed me how tight he got the insulation almost a R20 value for a 4inch wall depth and it was indeed DENSE PACKED!!! I was really impressed with Greenshield, they worked on my home for 10 hours that day. A project like this might have taken me a couple of weekends to complete. These guys have the right tools, competitive pricing, and dedication of performing quality work! read more

Ahmad and team are very professional, very dedicated and offered me a competitive pricing along with applicable rebates. I definitely recommend Greenshield Insulation for all the insulation needs. Amazing team. read more

Very professional, fast, and very competitive price. The deal is sweeter because they are also an approved contractor for various rebates. They did an excellent job for all types of insulation at my house: walls, attic, and crawl space. They cleaned up well after the installation. I highly recommend them. read more

I was looking for ceiling insulation. Checking with a few insulation companies (by Homeadvisor), I chose Greenshield as Ahmad's communication and workstyle just match what I was looking for! Because of Ahmad's professionalism, I ended up doing insulation for both ceiling, external wall and internal wall. Their staff (Parker and Dave) are also very friendly and efficient! I truly recommend Ahmad's team if you'd like to have insulation in your house! read more

We had an excellent experience with Greenshield. We met with several other insulation companies before meeting with Ahmed, and we chose him based on Greenshield's reputation, and his sincerity, and focus on cleanliness. On the day of the project (our attic and crawl space) they were at our house on time, and did a great walkthrough. They did an awesome job removing the old insulation: putting down multiple layers to keep our house clean, and using bags instead of free carrying it around the house and getting particles everywhere. They took before and after photos to show us the improvement, and we look forward to turning on our heat less! read more

I bought my home almost 3 years ago, it was a flip but they didn't put any insulation into the walls... In the summer my AC couldn't even keep the house cooler than 80 degrees! I finally decided to get a consultation since I learned about the PG&E rebates. Ahmad came over and gave us options and a quote. He was really nice about it, explained everything. I was comfortable with him so I didn't even bother getting any other quotes! They were so busy so we weren't able to get them to my house until a month from the quote but it worked out. His team did an amazing job, the guys were super sweet and moved a some furniture around that I forgot to do before they came without complaint. They started at 8AM and were done by 2PM insulating my walls, the blown-in insulation for my attic, and cleaning up (house is 1250SF for reference). I highly recommend them! My only complaint? They forgot to patch 1 hole.. :) read more

I hire Greenshield and Ahmad for putting wall insulation at my house. I can't say enough good things - he's probably the service professional i enjoyed most working with during my complete-house renovation. Key highlights: - Gave a quote in a very timely manner - Didn't overcharge or played games with the price - Did the job on the day he said. - Put an entire crew so work doesn't go beyond the allocated time - Everything was clean - Ahmad made sure I'm happy - He help me be educated on other insulation matters at my house. Would recommend to hire them! read more

We hired Greenshield in early June 2020 to remove and replace our old insulation with insulation batts that will be easy to move around if we need to, They did a great job and helped us qualify for a $1000 rebate. Ahmad is the owner, and he is super nice and excellent about staying in touch, visiting the crew during the job and he even came and did the finishing touches himself. The crew were excellent: Parker and Dave have been working as a team for years and have done hundreds of homes together. The weather was ridiculously hot when the project began, but they were troopers, never complained and were pleasant and professional. We will recommend this company to our friends and family. read more

Ahmed and his crew did an awesome job with installing insulation to my walls that had no insulation. Ahmed was very flexible and worked with my schedule as I needed it done quickly.

I am so happy I found Greensheild Insulation. I reached out online and got a phone call immediately from them to set up an appointment with the estimator. 2 days later we got a great price. The crew showed up right on time. They explained the whole process and there was no mess. They were in and out within 2 hours. I highly recommended Greensheild! read more

Professionalism is the motto of Ahmad and his crew. From start to finish they were exceptional! We had 4 companies come give bids, and Greenshield was the winner of our business. I am very happy we chose them. We had over 3,000 sq ft of radiant heat barrier installed, the ceiling air sealed, and an additional 2,500 sq ft R-30 installed over existing insulation in attic. I'm a big Yelper, and was concerned after reading several of the Yelp reviews. I did follow up research about the "questionable business license" comments, and I could not find anything out of place or wrong. Their license was up to date, workers comp, insurance, everything was as it should be. I'm not sure what the problem was originally, but its good now. Ahmad came dressed in a clean uniform, ID badge displayed, and immediately handed me a business card after shaking my hand. Before coming into my home, he donned booties to keep my carpets clean. He had all his necessary gear ready to go (Unlike other companies that went back and forth to their vehicles to get ladders, etc). Ahmad had in depth knowledge about his products and what would work best for my home. I must admit, I did lie to him initially so that I could test his integrity. I did A LOT of homework prior to his arrival. I pretended to be an uneducated homeowner to see what he'd tell me and try to sell me. I was pleased by his no-pressure tactics. He was very polite, and always addressed me as Sir until I told him to call me by my name. His bid was not the cheapest. It was actually one of the most expensive. We absolutely got what we paid for. Worth every penny. We chose him because he listened to us during our consultation and worked with us to solve our problems (Several other companies talked down to us and tried to force products/ techniques upon us). He was professional and made me feel like he cared about doing a high quality job. Ahmad was here everyday during the project too. This was comforting. I knew I didn't have to re-explain the project to new people. Ahmad kept me up to date on the project's status. Thoroughly explained what they were doing, what they were using and why they were doing it. They worked long and hard. It was over 125 degrees up there all three days! NEVER did I hear them complain, b!t@h, or whine. The whole crew was wonderful and worked very hard to produce a quality product and keep our home clean. There was a small oopsie. One their feet poked a hole in the ceiling. I pointed it out to them. Ahmad was super apologetic, and immediately got things in order to get it fixed. Patch was done and everything is great! I am OCD about projects in my home, and have very high expectations. My home is what protects my family so I take things very seriously. We could not be happier. Greenshield took great care of my home. We are exceptional pleased with their work. I highly recommend Greenshield! read more

Greenshield is excellent. Ahmad came to our house for attic insulation estimate on day 1. The job was completed on day 7. His crews were extremely professional and courteous. While they were working at my house, they were very careful of the house and laid down brand new floor coverings according to my request. The job was done quickly and professionally. We later received the approval of the energy saving rebate in a month. The whole process was very efficient and pleasant. I am glad that I found Ahmad for the project and will recommend him for all insulation projects needed in the future. read more

Greenshield came to our house to fix a terrible job done by another attic company. Ahmad was friendly, professional and thorough. He has a fantastic, clean and efficient crew. I would not hesitate to contact them again and to recommend them over about five companies that came out to bid on our house and certainly over the company that did the original work. read more

Greenshield was recommended by HomeAdvisor. From the first contact, the inspection and estimate, all the way through completion of the attic insulation, everyone, every step of the way, was very respectful and professional. I feel I received good value for the money I spent. Highly recommend. read more

They came and added installation to our house and did a great job. They came when they said. They were clean and tidy and got us a rebate too. read more

These guys got our house insulated and comfortable so quickly and so nicely! They were pleasant to be around and they worked fast and efficiently. They wore masks and kept distance from our household members. They kept the windows open while they were here for safety and then, after they left, we closed the windows and enjoyed the glorious warmth of an insulated house! They insulated the exterior walls on the first day and then finished insulating under the floor the second day. They also provided advice for future improvements of the house insulation with details on what needs to happen in the attic once we have some HVAC work complete. My toes aren't cold anymore and the heat pump is on less often! My roommate can now sleep and wake up comfortably without freezing. We are so grateful to their fast scheduling, efficient work, and great results! Thank you! read more

The team from Greenshield Insulation did a great job installing new insulation in our attic. They were always on time, worked fast and cleaned up everything afterwards. We can definitely recommend this business. read more

Top notch from day one! Ahmad was amazing. Came out and spent a decent amount of time educating us on all the different insulation options. We had no idea how much we DID NOT know!!! He was fantastic, so knowledgeable, patient and really explained things in a way that we understood. He was super responsive every time I sent an email with a question. They went above and beyond by helping us move things around day of installation. I felt comfortable while they were in the home with me, they went straight to work, no dilly dallying! And right on time! I can see now why their ratings are as high as they are! Look no further!!! read more

Greenshield did the insulation at our house a few weeks ago and the process was excellent from beginning to end. Ahmed was responsive and extremely knowledgeable. He educated us and what we needed and even was upfront on a more expensive option we were exploring for our crawl space that led us to not spend as much as we thought we had to. They did our exterior walls, crawl space and refinished our attic which was under insulated. It's been about two weeks and we've run our heater over 30% less each week! He also shared more about the rebates we would be eligible for and filled out the paperwork for us, something the other companies I got quotes from did not inform us of. Even the patch work they did was much better than what the painting company had seen in from others they said and not much prep work was needed to retexture and paint our walls. I would highly recommend them for all your insulation needs. read more

Update my previous review with my whole project being finished. Ahmad is very responsive and came out a few times to ensure everything is right. I really appreciate his dedication and professionalism. read more

Ahmad was very punctual and professional. He offered me several solutions and came in with a good bid. Often companies don't want to meet with just one of the home owners both need to be present. I was thankful that Greenshield did not hold up bids with this type of policy. Ahmad was able to answer questions my husband had over the phone. Abraham and his crew were hard workers, they put down the roll out insulation and the metal sheets along the roof lines and the job was done well - correcting errors from previous job and doing an excellent job of cleaning the attics before laying new materials. It was a 3 day job. There was one problem we discovered after he left - where a hole was in the ceiling and he promptly sent someone out to repair that hole and it is as if nothing ever happened. Honest,, hard working people that do a great job. I am glad we chose Greenshield and recommend them to anyone looking for a good insulation job and price. read more

Greenshield came out to my house last month and installed insulation in the attic. Ahmad came by and gave me a great priced quote and was very professional, so I went with their company. When they did the work they were very clean and efficient during the process. I would recommend them to everybody! Since then my house has been significantly warmer and have barely used the furnace during the night. I give them 5 stars overall. read more
