Testimonials

"When Brian and Brad came to look at the house last fall, I could tell from discussions with them that they were very knowledgeable about building and energy conservation. For parts of the job that I thought would be difficult to handle, they proposed several practical options.  I'm lucky I found them"

"Very impressed with GBS – they took care of me.  Their contractors were professional, knowledgeable and cleaned up after themselves.  And finally, it’s so nice to feel warm, not drafty, this winter.  I can see the wind blowing, but can’t feel it or even hear it."
