The work was noisy and their workday was long. But worth it. The price was not inexpensive, but we believe for the number of workers, and the extent of the work, the price was fair. It's not something I want to be good at.

The Founders team did a really nice job with our basement insulation project. The price was fair,…read moreand they were very responsive during the quoting process. The project was delivered on time and exactly as we had discussed with them. Where we were most impressed though was in the level of customer service they provided. After removing the insulation in our basement, we found a few surprises that were covered up by the old insulation. Founders was extremely accommodating as we worked with other contractors to get those issues (unexpected and unrelated to insulation) squared away. I realize having the other contractors come in was probably pretty disruptive to their workflow, and Brian and his team said he understood our situation and did everything he could to help us out. I will certainly reach out to them again with our next insulation project.

They may do this as a surprise, and if you let them in, you get charged. They sent us an invoice for $18,450.00 to perform remediation work. In my opinion, this is predatory pricing. We received other quotes for a couple of hundred dollars each, and they include a 1-year warranty. Shop wisely, I was encouraged by the inspection until I got the undisclosed bill for it, and then the follow-up with the $18,450.00 price tag. We went with someone else.
