"Owner, Jim Mass, responded promptly to set up a personal visit to explain the process and options to myself and my wife. Once the work was scheduled; crew arrived on time and work, including total clean up, was completed within the estimated time of less than day. All was completed within 1 week of the owner's initial visit. I would definately recommend Insulation Specialists to friends, which I have done."

"We have been in a 2 year long build with many facets. I reached out to Dason at the very beginning about the project and his professional insight was spot on. I had very specific engineering requirements for our build to achieve a very high performance, Thermal comfort gave us what I required. I had a previous Spray foam contractor from a prior build and received 3 additional bids for this 2020 project. I choose Thermal comfort from the 4 companies for several reasons and I am very pleased that I did. Closed cell IMO is the only way to go, that said the install is critical and the site crew was fantastic. George, was the lead and listened to my install concerns and did an excellent job. Rich and Walt were also on hand and also did great. They accommodated us the best possible in the timing of our project. They were thorough, conscientious and and their site prep and clean up was excellent. We have future projects and they will be our insulation contractor from now on."

"I requested an estimate for blowing insulation into my attic. Jim came out once to do an assessment, and offered a reasonable estimate. We scheduled installation. He returned on my request after I removed the existing insulation to reassess the attic. It was determined that there was already insulation blown under the floor, and Jim stated that he would not recommend any further work. Jim did not charge me for the multiple visits for assessments, and was very gracious about the necessity of canceling. I would recommend his services without reservation."

"Tyler was the first to respond to an Angi List search, came the next day, and told me that my attic insulation, while not perfect, wasn't in need of adding more. I appreciated his honesty, even at the cost of losing a contract. I recommend this company based on honesty."

"Oscar was extremely responsive, professional and was able to complete the job in a timely manner. He was open and honest about the product he used. He removed the old rolled fiberglass insulation for us as well. I would recommend DeAndas to anyone looking to have spray foam insulation installed!!"

"Was very happy with the work they did insulating my cathedral ceiling. They were very polite, organized and cleaned up after they had finished working. I could not get all of the old insulation out in some spots and there were some clips that needed to be removed. They took care of that for me, which I greatly appreciated. Great company to deal with. Also, thought their pricing was good."

Customers say: Quick response

"Specific project was attic, dense pack, and foam insulation. Very clean, friendly, and professional crew. Took the time to explain what they were doing, why, and what was wrong with what they found. Did a Focus on Energy assessment along with this work, recommended by Premier North, to make sure we let the science dictate the work. Very impressed with my overall experience."

Insulation questions, answered by experts

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.

You can buy pipe insulation materials in your local hardware store or in major home improvement stores. You can also shop for insulation online, where you may be able to more easily buy in bulk. When shopping, make sure you know your pipe's dimensions so you can buy the correct size of pipe insulation materials for your pipes.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

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.
