"Insulation NW did an excellent job of removing old inadequate insulation from an attic and crawlspace and replacing it with new insulation and wrapping the ductwork. They had two crews, one for the attic and one for the crawlspace, working for many hours to complete the job. A vapor barrier was also installed in the crawlspace. We paid a very reasonable price after the large PSE Rebate was applied."

"We had Lake Atitlan Insulation remove our old insulation and replace it with R-38. I enjoyed working with Nanni from the initial meeting to the final step of installing the insulation. Very knowledgeable lady and truly exceptional customer service. A highly recommended insulation contractor."

"I started this project months ago to completely reinsulate my attic with none of the experience; let me tell you, not a beginner-friendly DIY project. You gotta be Spider-Man to crawl around in my attic space, which I did numerous times. My friend and I spent 3 hours blowing insulation into the attic one morning, making our way through 12 bags of cellulose. After that I called Wallet-Friendly and I'm so glad I did. Martin reassured me with his confidence and plan that they would do a much better and safer job than I ever could. Plus they live up to their name! Two days later Martin and Gary distributed 58 more bags of cellulose in less than 2 hours. But I didn't order enough and we needed more! The cellulose arrived two days later and so did Wallet-Friendly Insulation to finish the job. Just in time for another heat wave!"

Insulation questions, answered by experts

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

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 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.
