I want to thank Atticali for taking on our rodent-control job and doing excellent work to help us…read morestop our rat infestation. Ours was a tricky project because our home is a townhouse that's one unit in a 6-unit building, and we're part of an HOA. Prior to calling Atticali, I had another company come out and do an inspection. They said the only way to solve the problem is to do exclusion work to seal all the places where rats are getting in across the entire building, including entry points on the common roof. But that company would not take the job because they were not insured to work on roofs and also because they didn't want to deal with an HOA. So, I called Atticali based on their good ratings. Irving was our inspector who came out and did a super thorough job of inspecting not only our unit but much of the entire building. I followed him throughout the inspection, which took about 3 hours. Some of my neighbors let Irving inspect their attics, where he showed me evidence of rats in each one of those attics. Irving identified many entry points on the common roof and verified that the only way to solve the problem is to seal all those entry points across the entire roof of the 6 units. I tried to rally my neighbors to have this job done together and properly because we all had rats in our attics and walls. But my neighbors were not interested. I also spoke to my HOA to see if they would cover the cost of the required work on the roof or at least approve this work to be done on our roof, since the HOA is responsible for the roof. (Note that these are one-story units with no access to the attics except for a small attic area above each garage, so the rodent exclusion work had to be done mostly on the roof and exterior.) Atticali was very accommodating and agreed to seal the areas they could in and above our one unit. They also agreed to work with our HOA regarding the required work on the roof. The two men who came did an excellent and thorough job, cleaning up all rat droppings and debris, and sealing all possible entry points. They did miss a bit of clean up, but once I pointed it out to them they cleaned the area very thoroughly. Even though we know it's not the ultimate solution (to have only our one unit addressed) and rats can theoretically get into our unit via our neighbor's unit, we have not seen any evidence of rats inside since then. Thank you Atticali!

Beyond easy experience with Chris. My dryer suddenly started giving off a burning smell, which I…read moremistakenly attributed to the lint catch being overloaded. But even after cleaning it out, the smell wasn't going away. Then the vent started giving off either smoke or steam, and in a panic I immediately turned off the dryer. Thank God I didn't start a dryer fire. The second I shut it off and made sure everything was ok, I opened Yelp and searched for a dryer vent cleaner. Chris's Insulation came up, he had great ratings, he was super close by, so after calling a different service and going to voicemail, I called Chris. Chris picked up after the second ring. When I told him that I needed someone to clean our dryer vent and what had happened, he said he could come out either between 5:00 and 6:00 pm that evening or the next day. It was already mid-afternoon when I called, so I was surprised to hear him say he could still come out same-day, but I decided to have him do that since I was free and also still a little shaky following what happened with the vent either smoking or steaming. Chris showed up during the window he quoted and wasted no time getting to work. He started the second he arrived and was done within the hour. His pricing was incredibly reasonable and fair and so far, in the couple of weeks since he was here, we've had no issues with the dryer. Before he left, he also sent us a ton of pictures of what the vent looked like post-cleaning. Super happy and relieved.

Professional and efficient, the two installers were in and out in 2 afternoons. Added spray cellulose insulation to attic and exterior walls. The house has wood siding in front and stucco on remaining three sides. They were the only one willing to drill hole through the exterior wood siding in front and patch. They also paint if owner provides the paint. The other two contractors said they had to drill holes from inside the house (oh no, we had just patched out walls after the electrical work). So far looks like house is staying cooler in warm afternoons. We shall see this winter!

I had my external walls insulated and they used cellulose to fill making 1.5 inch holes between the studs. Then they use a cork foam type backing to put in the holes as a vapor barrier and close it with stucco patch. Then comes the texture followed by primer. And if you provide them your matching paint they will color the patches too. They are nice and simple folks and easy to work with. Thanks I wonder why I waited so long to insulate the walls as the difference is noticeable and will save energy. They also help with rebates offered by state or federal.

My house had literally zero insulation in the walls and I was hesitant to add any due to mixed reviews, but I trusted Joseph and he delivered. Now I don't hear as much noise and the rooms feel a lot warmer. Then he did the attic by first cleaning it, then sealing it and filling it up to spec with quality insulation. My house used to have cold spots and heater would kick on every 20 minutes. Now there are no cold spots and the house stays warmer a lot longer and again much quieter from external noise. I would highly recommend his services.

I cannot recommend the team at GreenShield Insulation and the owner, Ahmad, highly enough…read more 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.

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!
