I needed a formal document called Heat Loss/Gain Calculations for my newly built house to prove that the builder has undersized a furnace for our house. Builder did not agree with my claim, and I reported the issue to Tarion as warranty claim. David was able to provide me with Heat Loss/Gain Calculations that showed in fact the furnace installed in out house was undersized. It was a crucial piece of document to support my claim.
I am very happy with David performance. Read more

We have a 130 yr old home in Cambridge and we hired D&D to re-insulate it. They firgured out the best way to insulate (they do a few different processes) and where it needed to be done. They didn't need to insulated the entire house - so that saved us money. They also took the time to show us where we could make improvements and now we are saving even more money on our heating/AC bill every month! They were polite, clean, knowledgeable and efficient. I would highly reccomend this company!Read more
