Wonderful husband/wife team and kept me in the loop as I needed a chimney sweep asap. I was treated with respect (I am a new transplant from Georgia to NH and didn't know anything about wood burning stoves) and received great instruction plus now I have a clean chimney. Looking forward to many years of continued service from Gilmartin!

They are extremely professional! The general man that came out and inspected our wood stove vent and vent for furnace. He was extremely knowledgeable about venting, masonry for chimneys, preventable issues, and even ideas going forward to name a few. I strongly recommend them! Great price on inspections too! (NOTE: I sure as heck wouldnt trust the person posting the one star review.)

I would highly recommend Gilmartin Chimney for any job relating to your chimneys! Brian and his team know their stuff and get the job done right the first time! Wish I had found them 20 years ago!

After noticing dust/lint building up on my siding directly under an exhaust vent I called to see if someone could come take a look. Brian was very accommodating despite his busy schedule. He was quick to diagnose the situation and even went so far as to clean as much of the siding as he could reach. I will definitely be calling again with any future needs.
