Herman I. says, "I highly recommend Founders Insulation if anyone is considering any insulation work. The communication with the company was easy and smooth. Jeff is the estimator and he is a true professional. He came on time and did a thorough examination in the attic. Jeff didn’t upsell me anything. He told me I had options and it would be up to me to determine what worked for me better. He was there to provide me information to make a good decision. The estimates came on the same day and Jeff answered my questions swiftly. I didn’t choose Founders Insulation due to my current circumstances. However, they are definitely a strong contender."See more

Berry M. says, "We purchased a home that was built in the 1940's and during the winters, the house was unbearably cold, making most of the house miserable to be in and the heating bills were extremely high. Our crawl space wasn't sealed up. After reading outstanding reviews, we called Value Dry and Jim Ketterer and his team were exceptional to work with. They inspected what needed to be done, gave me an estimate that matched what I paid them, and they guaranteed the work even with transfer of home ownership. We had the crawl space encapsulated, added a sump pump with a back up, a sump pump drain, a window well with drainage, and they installed insulation in the cement walls of the foundation to completely seal it. We also have a humidistat so we can control the humidity underneath the house. Exceptional job! Our coldest days outside were mitigated inside by the insulation and our house is very comfortable to be in during the winter now. They worked hard to make sure the job was done correctly and I highly recommend their services."See more

Reviews for Fairfax blown insulation contractors

Arn D.

I received couple quotes and knowing the ballpark cost of the job, most of the quotes were marked up 50-60%. Dale Thomas was the last contractor I was gonna get a quote from before giving up. Jacob was phenomenal! His quote was bang on mark to what my expectation was for VA. Jacob & his crew came on time, we’re very courteous & completed the ‘blown in insulation’ as I expected. I would hand down recommend this company!
