After all the updates we've made to the house we were still having energy losses. Brand new windows, solar on the roof etc. We decided to have an energy audit and got in touch with FOR. It was an interesting process to watch and we learned a lot. They were back here within the week to seal up anything that was leaking in the attic and improved our numbers greatly. There's a lot more that they offer to help your home become energy efficient but we'd covered most of that before hiring them. If I were to do it again, I'd start with them.
