Our steel chimney (30+ years old) was damaged and deteriorating. We called a few contractors in the GTA. Owen from A-1 Quality provided a competitive quote and noted the reason why our chimney had issues (roofer reinstalled a brace incorrectly). In the quote, Owen provided a WSIB clearance certificate, proof of insurance and his WETT credentials. Owen also walked us through any issues that could arise (ie risk of damage to steel piping that would not be visible until the chimney on the exterior was removed). Shortly after we agreed to the quote, Owen booked an install date. On the date, he arrived as planned and removed/replaced the old chimney the same day. Aside from the professionalism and excellent work, the attention to detail was beyond any expectation (e.g. placing a blanket on the driveway, under the work area, to collect any debris, dirt etc, wiping down the entire stainless-steel chimney to remove any handprints and smudges, demonstrating the best way to build a fire etc...). Friendly, professional and above and beyond our expectations. Highly recommend A1 Quality Chimney Cleaning and Repair!!
