We called in Green Stone Energy after a Peco audit recommendation and had two quotes. One was a bit more involved but also 80% more $$. They answered my many questions and upon recognizing at the start of the project they had forgot to include two small areas in their quote, they included the work itself anyway for the price quoted. The two gentlemen who came to do the work were kind, courteous and of no bother. They kept us informed through out the project and we felt very comfortable the service. I'd recommend Green Stone Energy on a variety of levels but a star also goes to the improvement to our comfort level in the house - that itself is remarkable. Why did we wait so long?
