Chimney leaks and rebuilds bring homeowners to GPG Masonry. An August 2026 Google reviewer said Gary resolved an ongoing leak that another company had been unable to fix properly, after providing what the customer considered a reasonable estimate. Google lists 5 stars from 17 ratings. One July 2026 customer hired GPG for a chimney reconstruction that became more complicated when Gary opened the old brickwork and found unexpected problems. The customer said he explained the problem, proposed a solution and updated the costs clearly. Gary worked alone on that project, rebuilding the chimney to match the house and leaving the site spotless. An April 2026 homeowner described a return visit after a chimney rebuild. When the homeowner feared that water was still getting in, Gary called back and traveled from Mashpee to Provincetown to investigate. The customer said a rushed paint job over earlier water damage had caused the scare, and described Gary making a hardware-store trip and trying a DIY remedy. In a March 2026 review, another customer praised Gary and his team for masonry work on a chimney, brick steps and kitchen, including correcting a problem the homeowner had not noticed. Older customers also described substantial chimney work. A November 2025 reviewer credited Gary with diagnosing a leaking chimney after other masons had recommended repairs that the customer considered unnecessary. A September 2025 review praised the replacement of an old chimney. In April 2024, a homeowner with a badly leaking chimney said Gary and his crew removed it, kept the timing and costs clear, and respected the property. GPG's work also includes walkways. In a May 2020 Angi review, a homeowner described Gary rebuilding uneven brick paths, reusing existing brick to reduce costs and adding cobblestone edging and granite steps. The customer also said he accommodated an added walkway branch during the project. Angi and HomeAdvisor each list 3.5 stars from 3 ratings and state that the pro is under review.
I highly recommend GPG Masonry. We had an ongoing chimney leak that another company was unable to fix properly. Gary came out, provided a very reasonable estimate, and quickly resolved the issue. The finished work looks beautiful, and it’s clear he takes great pride in his craftsmanship. He was professional, honest, and a pleasure to work with.
I cannot recommend GPG Masonry highly enough. I hired them for what we thought was a straightforward chimney reconstruction, but once they opened the chimney up, they discovered significant, unexpected issues hidden behind the old brickwork. Instead of delaying or abandoning the project, GPG handled the entire situation with absolute professionalism. Gary clearly explained the problem, and presented a solid, expertly thought-out solution along with a transparent and fair update on costs. Gary’s skill and craftsmanship are truly top-tier. He worked alone on this project and rebuilt the chimney flawlessly, matching the aesthetic of my home perfectly, and the final structure looks incredibly solid and safe. Despite the unexpected hurdles, Gary worked with patience and precision and left the entire job site completely spotless. If you want a master mason who can handle any challenge with honesty and skill, hire GPG Masonry!
Gary was amazing! He really cares, and knows, about his work. He has also excellent communication skills. He came to do the work when he said he would. And it was all a pleasure to work with him. But the real kicker happened when I had a scare a week after he took down and rebuilt the chimney: a rushed paint job over some water damage caused by the previously leaking chimney made it seemed like there was still some water intrusion. He immediately called me back, came all the way to Provincetown from Mashpee to thoroughly investigate what was going on. When he figured it out, and it was in no way related to his work, he went over and beyond (including a trip to the hardware store and experimenting with some DIY) to leave things in a better state than he had found. Would recommend working with him hands down.
Gary and his team did a wonderful job on the masonry work I needed done on my chimney, brick steps and kitchen. His response time was exceptional. He took the time to listen to what needed to be done and assess the situation himself and applied his expertise. He and his team put in extra effort to correct a problem that I wasn't even aware of which was very much appreciated. He is affordable and stands by his work. I would highly recommend reaching out to him for your masonry needs.
The very best mason in the area. Gary treats his clients like family and truly puts integrity into all of his work whether it is a small repair or full chimney rebuild. He is responsive and was accurate in diagnosing our leaky chimney while other companies did the bare minimum. Multiple masons recommended repairs that were not even necessary and would have wasted us thousands of dollars. We obtained multiple quotes for a repair, and Gary’s expertise was far more apparent than other masons in the area. We will be using him again for any needed masonry.
