"Great! Just one of the best home improvement vendors I’ve ever worked with. Excellent service and great work. Joe was super attentive to spotting and troubleshooting problem and worked incredibly well with our neighbors (we live in a brownstone). He worked quickly."

"We were unable to get our pellet stove running, so we found Caliber Chimney though Angie's list. They were able to fit us in the next evening and got us up and running. He was very professional and knowledgeable."

"I called Horizon after moving into a new home in Medway and having no idea what condition the chimney was in. They sent a team out the same day! The guys were great - very friendly and professional. They looked everything over, informed us that one chimney needed to be cleaned but the other did not, and some of the brick work was loose on the fireplace floor. I also requested a chimney cap and they suggested strengthening part of the chimney before installing. They provided an estimate within 24 hours and came out about a week later to do the work. Again, they were completely professional, pleasant and somehow despite cleaning the chimney and doing masonry work, did not create any dust or mess in the house. I was so pleased that I asked them to put us on a yearly schedule for routine cleaning. I highly recommend!"
