Report
Through our 70 year history, we have worked on over 11,000 different homes, so there is nothing we haven't seen! But don't just take our word on it, read what our customers are saying about us. Just wanted to let you know how happy we are with the work done on our home. The laborers you sent to our house were absolutely amazing, kind and professional and cleaned up after themselves better than any other contractor to walk through these doors!
Attic Insulation
Report
Insulating the floor is a very good option if available, it enables you to easily get to the Heat resistance code of R38. It also leaves open the option of raising that value higher in the future. By insulating the floor of your attic you cut off that attic space and no longer heat that area. Insulating Rafters with prop-r-vents is good to create more conditioned space without loosing the roof ventilation. The only down side to Prop-R-vents is that the actual vents take up an inch of space which reduces the potential R-value of that space.
Basement Insulation
Report
Is your Basement Properly Insulated and Air Sealed? Many drafts and cold air will enter a home through its basement and drive the warm air in the house out. Perfect for hard to reach crawl spaces with dirt floors, or where not a lot of insulation can be added. Basement ceiling insulation is important to keep cold air out and floors warm on first floor.
