"Attic Insulation Lab worked at my house adding insulation to the walls in the garage and covered them with drywall. Their price was within our budget and we heard good things about them as well. Eran and his team of 3 additional workers did the whole job and they worked each day till they finished it. The office personal were good too. They were very flex with us in regards to the work hours and days. We do recommend this company and mainly Eran."

"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"Scott made some great recommendations and didn't seem to want to include add-ons that weren't necessary. As an example, I asked about a gable fans but he identified that the roof was already well ventilated. He also did a great job educating me about blown insulation. He showed up on time and completed the work on schedule. The only complaint I have was that his work crew knocked some of the recessed lighting around doing some minor cosmetic damage to the ceiling. I identified the damage and his solution was to reseat the fixtures without really fixing the damaged drywall."

"What a terrific company! All Type Insulation Services Inc team is extremely knowledgeable, reliable and courteous, and they offered some excellent solutions to the noise problems in my apartment. Ron was readily available and nothing was too much of a problem for him to handle. I would certainly hire them again and I strongly recommend them to any business or residence that has a noise issue and need insulation service."
