Hannah in Toronto

Knox insulated our attic and then did the replacement roof on our addition. I had brought them in to do a major roof repair where I worked. The ceiling in my son's room was peeling and cracking and they came to take a look (we thought there might be a problem with the insulation work). Turns out it was a really poor job done on the chimney stack by a previous contractor - it wasn't sealed properly so water was seeping in. Knox came in and did the repair at no charge!!! We love them.
