ThermaGuard, Inc. Reviews

“They did an excellent job, were very concerned about my satisfaction, and were competitively priced. Hard to beat that combo!”

James N.

“They are wonderful people! They put siding on my house. The cost was very reasonable. They are very personable, I can't say anything bad about these folks, you can't go wrong with them!”


“Thermaguard was recommended by a friend. I having nothing but praises for them! They put on a new roof and installed new siding. The workers were very professional and cleaned up well. After they installed the new roof, they went over the entire yard many, many times with a magnet device picking up loose nails. They are very reasonably priced which is one reason I went with them. I have never regretted the decision to choose them!”

Ms. L.

“Allen and Marilyn were easy to work with throughout the entire project. The quality of the products they offered was outstanding as were all their installers.”

Cedric D.

“ThermaGuard replaced siding with Hardi Plank and painted the exterior. I would recommend them to anyone. They did a great job in a reasonable time. They are fairly priced and are very friendly.”
