Avalon Masonry is James — reviewers name him in nearly every account, sometimes alongside his son — and what he is best at is brick and stone. A homeowner in September 2025 had a chimney rebuilt from the roof up, a new cap fitted, the rest pointed, power washed and sealed, all at the quoted price, with a few loose bricks on the front stairs patched at no charge. Another in June 2025 had a patio and walkway that came back looking new inside a week of the first call. Jobs on file run from $4,000 flatwork repairs up to a $30,000 brick and stone project in August 2025. Its Massachusetts home improvement contractor registration, number 209986, is active. Speed and communication are the recurring compliments. A reviewer in June 2026 said James came within hours of the call to look at the job, quoted it, and did the work when he said he would. Others describe being told what was happening at each stage, the work explained before it started, and the site left clean. Then there is the chimney. In April 2026 a customer wrote that they paid $2,200 to repair a leaking chimney under a contract quoting a five-year warranty on water leaks, and that nine months later it was still leaking — and that the company would neither honour the warranty nor refund the money. The same complaint appears on Angi that month, adding that Avalon came out after a video of the leak was sent and then stopped responding. That is the sharpest thing here, and it is recent. The platforms disagree about this company more than most. Angi and HomeAdvisor both sit at 4.9 across 39 ratings; Google sits at 3.0 across two; the Better Business Bureau grades it C and shows one complaint on file. For flatwork, steps, retaining walls and foundation masonry, the accounts are specific and consistent, and holding to the quoted price comes up again and again. For anything sold on a warranty — a leak repair above all — put the warranty terms, the remedy and the response window in the contract, and settle before you pay what happens if the water comes back.
Avalon did a great job of accessing and resolving the job needed to be done on and around my foundation. They kept me informed on every step of the process. I would highly recommend them for any job that you may have, they're efficient, and very professional, the job was done quickly. They are a FIVe Star company and would highly recommend them. Thank you Avalon for your hard work and I love that you kept in touch with me through the entire job
