Dorin's staff did a very good job insulating my walls for a budget friendly price. I would definitely recommend his services. read more

See all

I recently had insulation installed in my home and I am extremely satisfied with the results. My 60-year-old house has never experienced the joy of having a warm blanket of insulation in the attic or crawl space. With the cost of gas going up everywhere I knew I needed to get this new (to me) gal some insulation. A friend of mine recommended Dorin's Insulation and I'm so glad I took his recommendation. His quote was good, but his service was even better! Dorin was professional, easy to communicate with, friendly, and knowledgeable about the product and process. The installation itself was quick and efficient. I look forward to seeing savings on our heating bills. Thank you for a great job Dorin! read more

This is the second time we have hired Dorin's Insulation to insulate our house. In 2018, they insulated the floor and the attic of the house since there was no previous insulation. Since we are in the midst of a remodel on that house, we once again hired Dorin's to insulate the walls that will not be insulated during the remodel. On Monday, I called Dorin and made the appointment for an estimate on Tuesday. Tuesday afternoon, we had a quote. Insulation was blown in and completed on that Friday as promised. We highly recommend Dorin's Insulation because they respond quickly, have fair pricing and do excellent work. Dorin Jr. is very professional, polite, trustworthy and knowledgeable. We highly recommend this business for your insulation needs. read more

We knew our walls had zero insulation and that we wanted to get the drill n fill insulation for them (our attic already had insulation installed by the previous owners). Dorin's Insulation was a referral by my brother who's worked with Dorin in the past. At first Dorin was hard to get ahold of, but once we finally connected, Dorin was awesome. He took the time to explain the process and answered all my questions. I gave him our wall dimensions, and he promptly provided an accurate quote. I immediately book Dorin and found out he works Saturdays and felt he could get our house insulated in a day. Woohoo! Dorin showed up a few minutes early to his 9am Saturday appointment during the hottest day during the most recent heatwave...whoa. I couldn't believe it. As soon as I showed him the walls, his crew got to work right away. I was seriously impressed by the hustle n drive of these guys...I was worried it was going to drag on ALL DAY and impede my kids' naptimes. NOPE!! They were efficient and timely. In just about 4hrs my walls were insulated. It was an absolute pleasure doing business with Dorin and I cannot speak more highly of his work. Since we got insulation, my infant babe has slept better. I am so thrilled to have insulated walls. Oh and a bonus: while working on our house, a neighbor approached him for his business card cause they want insulation too. Yay! Oh and I referred another friend too. We paid exactly the quoted referral amount too btw. They did an excellent job of cleaning up all the dust and debris afterwards too. THANK YOU DORIN!! read more

Great price, solid work, and friendly. These are three of my favorite things to find when I hire a contractor, of ANY kind. Thanks again for a job well done! read more

Highly unresponsive. Did miss first appointment, then very slow when writing an offer. Repeated emails, phone calls and messages just got ignored. read more

Provided a very honest opinion. Does not try and up sell. Would recommend. On time and actually came back since I was running late.

Five star service! Dorin is great to work with and goes out of his way to make sure everything is completed efficiently and correctly. Conscientious and caring about what he does. Very knowledgeable about his business and was the best price I found. His personality and sense of humor are the icing on the cake. read more

I usually don't write YELP reviews unless I feel compelled and this Guy (Dorin) deserves to be recognized. As I was in the middle of installing LED lights for my house, I was told that my insulation is bad and had to be replaced. Dorin was referred to me by another contractor and trust me I had my reservations as any home owner does. Besides, he was referred by a contractor with whom I wasn't thrilled with, let's just say :p But, Dorin was a breath of fresh air. I was instantly impressed after the first phone conversation and so I had him come over to my house. Now, here is where it gets interesting. So, he comes and inspects my house and gives me an estimate to remove old insulation (fill-in kind) and replace it with BATT insulation and add radiant barrier (aluminum foil thingy). I asked him 2 simple question: "should I do this? and do I need this now?" . His response was the reason I gave him the contract. His response was "No you don't have to? You can get away with $600 by him just refilling". He could have said, "oh NO, you must do it now and put a scare in my mind".. That was enough for me. He wanted my contract but he didn't want to capitalize on the situation. Honest, Honest Guy!. He was clear, educated me with what was wrong, what needs to happen & how long it would take. Oh did I say, his price was reasonable and he doesn't haggle?. One price and NO EXTRAS! He was professional, courteous, discreet and delivered awesome, as he promised. He left the house the way he found it. Vaccumed it and took the trash. Please, if you need insulation, CALL DORIN. !!! World needs more Dorin's ...Honest contractors are hard to come by. He is one of rare ones who understands, "Business is not over when the payment is received. In fact it is he beginning of a healthy business relationship". Congratulations Dorin, On a job well done!!! Oh if you think this review was given to him by one of his close buddy's (happens every now and then on Yelp) to boost his market value well, you call me. My phone number is 4083074183. My name is Clement and I assure you, I am in no way related to Dorin :-) read more

I'm about as picky as it gets when it comes to people who work on or in my home (see my other reviews). We recently hired Dorin to add new insulation to an uninsulated attic and couldn't be happier. In addition to his prices being extremely reasonable, his work was outstanding. He's also the nicest tradesperson to ever visit my home and is extremely enthusiastic about his work. Seriously. Rarely do you see someone in this business so engaged and eager to work his a.. off. Beyond doing a thorough job on the air sealing and insulation (not easy or effortless work in my tight attic), Dorin and his colleague were extraordinarily clean workers. They took extreme care to cover my floors for the path that they carried insulation and did not leave a single mark on the walls or other trace that they had been here (apart from the home being warmer). Contrast this to the DirecTV guy who left piles of sheetrock dust and footprints everywhere after making a tiny hole in the wall. Thanks Dorin! read more

Professional, Reliable, Affordable and Knowledgeable. Dorin is great to work with too! Very nice guy. Our project required both spray foam and batt insulation. Dorin and his team worked a very long day to complete the job, which we greatly appreciated. Dorin has excellent references, years of experience and does a great job. Call him for all your insulation needs. read more

The guys from Dorian's did a great job. They were courteous, professional, friendly and priced reasonably. I am extremely satisfied with their work and would highly re-examined them to all my friends and family. read more

If you need to have your attic insulated, Dorin is the one you should choose. He showed up on time to look at the job and give me an estimate. He didn't make me feel rushed and stayed to answer questions. He definitely makes you feel comfortable and will help educate you on what the process involves. He won't try to push other products if he feels you don't need it. The job took only a day, his crew was clean and professional. R38 in the attic, air sealing, and radiant shielding installed. This job was actually done back in August. The rest of the summer was very comfortable even when we hit 100 degree heat. I kept calling my wife on those hot days to see if it was cooler inside than it was outside. Now that the cold weather is here, our heater doesn't turn on as much as it did last year. Still warm and comfortable. Thank you Dorin. read more

Dorin is nice and very punctual. His crew worked hard to remove the old pallet type of insulation materials and put all new R30 pads on the attic. Immediately I could see the effects. In the last couple of days, it has been clear sky and I saw room temperature is at least 5-6 degrees lower. I got four different quotes. Dorin's price to put R30 pads is the lowest and he was willing to match the price quite I got from another company. Dorin came back and did vacuum cleaning of the worked area because his crew forgot bring the vacuum cleaner when they did the job. Thanks for keeping your words and work ethic. read more

Dorin is a super friendly guy and knows his stuff. He did a closed-cell foam ceiling install in my two-car garage and batting in the walls, only days after my asking him to come give me a quote. His guys came in and were very friendly and respectful, carefully masking off and moving out of the way personal items that were in the garage. The work was done in just a few hours, and they left everything cleaner than when they arrived! His price was excellent as well--the best of all the quotes I got. I recommend him without hesitation. read more

I called to get an estimate and Dorin arrived within about an hour. He gave me an estimate that was about $200 less than the other one I received, was friendly and personable, and explained the type of insulation and why it was the better choice. He showed up within a week, was on time and got the job done quickly. I'd recommend this business to anyone and would gladly contact him again. read more

We were looking to get subfloor insulation (we have a raised foundation) as we recently got new windows and it still felt really cold in our house, particularly the floors themselves and inside closets and cupboards. I called Dorin, thanks to his yelp reviews, and he came out same day to give me a quote. I got only one other quote and it was significantly higher than Dorin so we called him the next day to say we'd like him to do the job. We scheduled the work to be done 2 days later and they arrived right on time, in fact, a few minutes early even, and they were done in about 2 hours. The best part is that we notice a significant difference in the warmth of our home now! In fact, our house has stayed about 2-3 degrees warmer since the installation. Thanks Dorin!!! If we ever want to tackle the walls, we'll be back! read more

Dorin and his crew (3 guys) just finished installing insulation during my interior remodel. Currently no drywall (yet) so his crew installed the R38 pink batt stuff in the attic, R13 in the walls, R19 below the floor. On time (8am) worked fast, great to deal with, awesome price. They finished and cleaned up in about 5 hrs. Passed building inspection no problem. Dorin is an honest, friendly, easy to deal with fellow. Would use him and his crew again in a heartbeat! I wish all contractors were this good! read more

I worked in a project in Oakland and we needed the entire house insulated. After checking 3 other contractors, we choose Dorin's Insulation. The best decision. Dorin was simply delightful to work with. He is one of the most polite person I ever met. He ALWAYS answered his phone promptly and if I left a message, he followed up by calling me back very shortly. He and his crew came over to the job site when he said they would, most importantly, they did their job right the first time. Doris and his crew are professional, knowledgeable and skilled at what they do. I will definitely work with Dorin again and I highly recommend Dorin's Insulation. Great job!! read more

We just had Dorin install insulation in our attic. He and his crew showed up early and were finished in about 90 minutes (smaller house). He was able to fit us into his schedule within a week and we are so pleased with his efficiency, professionalism, and pride in his work. You know quality matters when the guy whose name is on the truck is up there working too! read more

sorry, he doesn't know how to do retro-fit walls with cellulose - a lack of experience - so you can't get the 'full monty' & new pg&e rebates!!! read more

I got my insulation project done from Dorin for attic and walls. Checked few quotes and Dorin's is the best. He arrived on time with his crew. Got my walls and attic insulation done. He did very good job with both. Removed all my old blown in bad insulation and installed R30 batts. His crew is very professional. Dorin is very knowledgeble, professional and provided warranty services very well. Recommed Dorin for any insulation project for your house. read more

I can't say enough positive comments about Dorin's Insulation! My rating is actually 5 Stars times 2 or 3! From the beginning to the end the process & exceptional Customer focused service is far above the average experience. I would recommend to anyone I know to call Dorin's Insulation for any Insulation needs. This was the first Insulation ever installed in my 100 year old house. I also want to mention Michele Miranda, Ygrene Regional Account Manager for everything she went above & beyond for. I volunteer to be contacted if ever needed to anyone looking for previous customers for the completed Insulation work I had done as a very satisfied customer! read more

This is a long overdue review for Dorin, but much deserved. Dorin and his crew insulated our home last October and did an awesome job. All of my interactions with Dorin were positive. He visited our home and provided various options for insulation and an estimate for each option at a competitive price. We decided to do insulation in the attic, under the subfloor, and all of the exterior walls. Dorin and his crew did the work in a matter of a few days and cleaned the outside so there was no leftover mess. He is extremely easy to work with and good at what he does. He also takes responsibility for all of his work and provides an amazing warranty. Thank you so much, Dorin! Our hardwood floors are no longer cold in the winter, and the house is warmer than before. read more
