Since 1948, Bonham Insulating Company, has proudly served the residential and commercial communities of Spartanburg, S.C., and the surrounding areas, including Spartanburg, Union, Greenville, Anderson, Easley, Cherokee County and Laurens County. We strive to provide each of our clients with an unparalleled professional contracting experience, from design to project completion.

Competitive Pricing

Not only was my phone call answered the first time I called without going to voicemail, but every person I dealt with from the company was professional, information, and easy to be around. Service was a quick turn around and their prices were very competitive. We had the insulation in our attic sucked out and re blown while redoing our ceilings, and while doing so, their crew shared great advice and information regarding proper maintenance and upkeep of our attic. Highly recommend, and would use again if needed.

Quality Customer Service

I cant say enough about this company and their professionalism. Its not often things go so smooth from start to finish with contractors, but this guys went above and beyond. I was overwhelmed with customer service and the quality. Highly recommended Kevin and his crews.

We had a great experience with Kevin and the Bonham team. They responded quickly to an inquiry we put in regarding insulation at my office and quickly helped us identify and resolve the problem. Responsive, professional and a great group of folks to work with.

Great Communication

A business is rarely comprised of more than one good communicator and employee but I was impressed with all five of the guys I dealt with during their services. They followed through with all of my concerns and even made other good suggestions regarding managing critters entering our attic space as well as a good referral to a roofing repair service.

Highly recommend!

I wanted to make my home more energy efficient and after research discovered that having enough insulation is one of the most critical things that you can do. I called Bonham Insulating and the owner came out to my house to inspect my attic. He recommended blowing additional insulation into the attic space. His team was able to blow it in without any trouble, they were neat, nice, and professional. And the best part? I noticed an immediate difference in how much my AC was running. And when I got my power bill, I noticed it there, too. Highly recommend!
