"David and his team were very professional and the work they did was excellent---we could tell the difference the next day. The temperature on the 2nd floor is several degree lower than before due to the new insulation and feels much more comfortable. David has solid knowledge regarding insulation and he explains things clearly. Definitely would recommend David and Prudent Homes to my friends and neighbors."

"I've been trying to find an expert in insulation for months to come out and tell me out to properly insulate around a removed chimney and Comfenergy was the expert I needed. Even though the insulation part of the job was too small for Comfenergy (wasn't above their minimum quote value) they were happy to give me their expert advice and I appreciate the time spent as I now know what to ask the roofing contractor to do in order to insulate this correctly. Thanks!"

"It was amazing, took all day to get the old insulation out, seal the holes, and refill with new insulation. Would recommend this company to anyone looking for a professional service to improve insulation and save money on heating and cooling costs."

"I am very pleased with how my attic insulation project turned out. when the company came to my house to give an estimate they evaluated my current insulation, told me what I needed to bring my home up to the current standards for attic insulation. (r49) more importantley they told me what I didn't need. I highly recommend this company for your insulation project."

"Founders Insulation did a very good job on installing insulation in ceilings! They were careful, courteous and cleaned up."

"These guys were the benchmark for contracting work. Quick estimates on pricing that they stuck to. Timely quality work, and a great clean-up effort. 10/10 would recommend for insulation work."

"I was impressed with the quality and skill of the crew, they knew exactly what to do and the result was excellent. I was extremely impressed with the quality of the insulation, and feel much more comfortable with my home! The foreman was excellent, very skilled, and the turn out was outstanding!"

"They wanted to inject very expensive sealant into the ducts to seal the seams. The company I hired used insulating tape over the seams instead, for a greatly reduced price. The total price difference in their proposal and the company that I hired was about $4500."

"Excellent service and professional work. The only problem was a broken sprayer for which there was no spare that delayed completion. The company refunded our extra hotel night and the owner John LeVan came out personally to ensure clean-up was done correctly and that their work met our expectations. This was also the only company of four that gave an appraisal that provided health and safety information on the product and how ventilation should be performed!!!"
