"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"Attic Air absolutely lived up to their reputation. They did a GREAT job! I did my research in creating a short list of 3 bidders for the job. I have a bi-level house (4 levels) with 2 attics. We had black mold on the underside of the roof which we had remediated a week before having Attic Air come in to fix our ventilation and insulation issues. Our upstairs floor was cold in the winter and hot in the summer. The attic ventilation and insulation needed to get fixed, and I wanted to make sure I hired a good company to do it the right way so I never had to worry about it again. I made the right choice. The temperature throughout the house is so much more even now. Before Attic Air came out, the basement and sub-basement were freezing and the first and second floors were warm and hot. My over-sized top of the line Trane a/c unit was working overdrive to try to cool the 2nd floor and never could do it. The top floor is so much cooler now than before. It's really going to save my a/c unit in the long run. Attic Air was not the lowest bid of the 3, but you get what you pay for. If you want to get the best quality this is the company you want. I would haven't have changed a thing. Worth every penny!"

"Koala Team was excellent starting with John Anthony giving us a quote immediately after looking at the space. He told us about a rebate and applied it off the top. Team showed up on time, they were neat, did a beautiful job of putting the foam insulation in. We are very happy and would definitely recommend Koala to our friends and neighbors."

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

"We reached out to Dan with the issue of freezing pipes and cold rooms in our old house. Dan inspected the house and proposed a plan to remedy these issues. Aside from the more traditional air sealing and insulation solutions, Dan also recommended insulating the area of our house above our soffit, which was difficult to access but that appeared to be a major insulation issue. I should add the other firms we requested quotes for did not identify this area in their proposal. I firmly believe the proposals from the other firms would not have fixed our issues. Dan worked for ~2 weeks on air sealing our attic and house, adding insulation to our attic, removing our soffit and adding insulation and reinstalling soffit. Work was done well and within budget and at a fair price. Dan is very easy to work with and takes pride in his work. We are very happy to report our pipes have not frozen and the cold rooms are no longer cold - would highly recommend Dan to others - he went above and beyond."

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

Insulation questions, answered by experts

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

The R-value is a rating that measures an insulation's thermal resistance—in other words, how well it insulates. A higher R-value provides more protection for your pipes, and all pipe insulation materials should have an R-value listed on the product description or label. Each insulation type has its own R-value, which typically falls between one and five for most pipe insulation. When making a selection, Energy.gov recommends choosing a pipe wrap that is at least one inch thick, and the International Code Council (ICC) suggests choosing a material with an R-value of at least 3.

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.
