"I could not have been more pleased by the work and the professionalism and the cost and the results. ABI was the first company to respond to my request for bids on the project. They were at the house within days of the request and were knowledgeable about putting insulation over light fixtures embedded in the ceiling. The attic did not have access from within or outside the house and they problem-solved this in a way that was a great solution. They lay down mats so as not to dirty up the carpets and stairs and they wore gear to protect themselves from the insulation. MY house was cleaner when they left than when they arrived. All of the people working on the project were professional and knowledgeable and the cost was extremely reasonable. For the first time this winter, my house feels like it can hold the heat. Looking forward to this summer, because I'm betting it will also improve my air conditioning!"

"I was plagued with recurring ice dams in a few areas of my roof. After investigation, it was discovered that the insulation in a few visible areas was sub-par. Roland came in and quickly spotted the problem areas. He assured me that the could fix these problems immediately. He used a combination of rearranging existing batts, blown-in fiberglass and spray foam to seal the attic space, over the course of two visits. He's extremely personable and always called me back or answered the phone right away."

Insulation questions, answered by experts

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.
