We hired Pipe Works Services to install insulation in our basement ceiling between the boards. They worked closely with us and moved some things out of the way for maximum efficiency. Pipe Works did a good job and we were pleased. It seemed as soon as we walked back into the house after the project was completed, the floors already felt warmer. We are thrilled with the results and would definitely use them for other services. I've already recommended them to friends. I'm usually apprehensive about spending that kind of money on a company that might just be scamming me, but we were pleasantly surprised. I highly recommend Pipe Works Services.
