"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."

"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!!"

Insulation FAQs, answered by experts

As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.
