What Our Customers Are Saying

We treat our customers like neighbors—because they are. Their reviews reflect the care we put into every job.

All of the employees including the office personnel were the best. Evan came and inspected we sat down together and he explained everything we needed. The installers were here on time as scheduled. Very nice gentleman and hardworking. We were sent pictures when everything was done and they had done excellent work. Thank you to everyone at Vance Installation and we will recommend this company to everyone.

Loretta Moneymaker

Fabulous folks to deal with. They have been in business forEVER. Evan visited to walk/crawl the job site and answer my questions then followed up with a quote. Logan, Brandon, and Stephen pulled out our old insulation and strapped in R30. We had a tiny (water) thing go slightly wrong but they made repairs and everything was fine. Jan installed our new crawlspace access door. Vance Insulation will return this month to do our vapor barrier. The office ladies (Brittany1 and Brittany2) are very knowledgeable and helpful. Excellent folks to deal with!

Tara M

Vance Insulation was phenomenal! Mr. Jeff came out and was extremely friendly. Their prices were great and the crew did a great job. The quality of work was exaclty what we wanted for both the attic and crawl space. I recommend for all insulation work to go to Vance Insulation!

Reid Clingerman

Vance Insulation is an honest business. I was referred to them from family who used their services and were very pleased. I called to have a free estimate to assess and fix the insulation in my attic. Harold came to our house and told me that there was no insulation in the attic and recommended reaching out to the builder. He could have done the job and charged me, but instead he made a recommendation that resulted in repairs for free. I cannot thank them enough! They have earned my business for life! Thank you for your honest business practices, it really made a difference for us!

Jaclyn Crowley

I have had several experiences with Vance and from start to finish has been great. They promptly arrived to both the estimate and the day the work was being completed. Worked quick, efficient and cleaned up behind their selves. They added blow in insulation to my attic which brought me to code and decreased my heat bill in the winter months 80-100$ every month! Very professional and they should be proud of their work. Thank you and your crew!
