"I couldn’t be happier with the service I received! From the very beginning, the team was responsive, friendly, and great about following through. Scheduling was convenient, they arrived right on time, and the spray foam insulation work under my lake cabin was completed promptly and professionally. Chris was especially friendly and a pleasure to work with. Their pricing was competitive, and the entire experience was excellent from start to finish. I highly recommend them to anyone looking for quality spray foam insulation work. It’s refreshing to work with a company that delivers on its promises!"

"Roland did an excellent job. He explained the things I needed and those that I didn't. He was right on time and finished the job in the time he stated. He was very professional and knew what he was doing. If you are looking for a straight shooter without any of the sales frills (and the larger cost) then Sav-On Insulation should be your choice."

"Very professional, very efficient. They covered everything in the room where they had access to the attic. Cleaned up after the job. They put some extra insulation in and didn't charge extra. Stuck to the original estimate."

Insulation FAQs, answered by experts

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

An outdoor spigot needs some attention before the temperatures begin to drop. Using an insulative cover is just one part of minimizing a frozen spigot and pipes. You’ll also need to shut off the water and drain the spigot, which leaves as little water as possible in the pipes to prevent freezing.

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.
