Called Gary on a referral from my HVAC company because they found my chimney for the oil burner was blocked. Called as soon as the tech left. To make a long story short, Gary and Andrew were able to come out in a couple of days because of rain and other scheduled work. They came and did a full inspection on all 3 of my flues. They took pictures of everything and showed my wife what they found which included needing a liner for the oil burner, a cap for our fireplace flue, repair of the crown. For our coal stove, the crown needed sealed. He found that the other flues had heavy downdrafts, so we capped the coal stove as well. They came back the next day to install the liner and cap on the fireplace flue. Will need to wait for warmer weather to repair the crown. Both Gary and Andrew are very courteous and take pride in their work. They did an excellent job and I would highly recommend them. Will definitely use them again and on a regular basis.
