They were responsive, professional, on time and did a great job! Costs seemed reasonable compared to others. First they came out to do thorough level 2 inspection using a camera to view the entire chimney flue (as well as visual inspection from roof and a look at the brickwork inside the attic where the chimney comes down into the house). They identified issues with the liner and exterior cracks/wear that had let in water, which needed repair. The inspection has a fee, but the estimate for repairs is free. We opted to get the exterior repairs done this summer and have them back in the fall to do the interior liner repairs. The same technicians who did the inspection came back and did the repairs which required three visits. Work included repointing the bricks, rebuilding the crown, replacing the cracked clay liner on top, and replacing the cap damper system (visit 1), returning to seal the flashing and clean exterior (visit 2), and finally waterproofing exterior (visit 3). During the first visit they also did a chimney sweep. The technicians were knowledgeable, courteous, and cleaned up nicely after they were done each time. We look forward to having them back in the fall to replace the chimney liner.
