A 468 sq.ft. antiqued flagstone stamped concrete walkway wrapped around a customer's house came out amazing at first, according to an April 2023 Google review of Provencher's Decorative Concrete Flatwork & Floors. After the first and second years, they wrote, the top layer started chipping and flaking off, and Bob Provencher would not answer their calls, texts or Facebook messages. They wrote that two different professionals who looked at the chipped sides and flaking called it negligence, pointing to air trapped in the concrete, the release being hand tossed and edges that were not rounded or bullnosed. In a February 2014 BuildZoom review, a customer called Provencher Flatworks a professionally run company with knowledgeable, quality work; a week earlier, in another February 2014 BuildZoom review, a customer recommended it as a professional concrete company. The business works from Windsor Road in Chelsea, Maine, and holds 5.0 stars from 2 BuildZoom ratings and 1 star from 1 Google rating.
We had 468 sq.ft. Antiqued flagstone stamped concrete walkway put in wrapped around our house which bob provencher portrays this work on his sites. It came out amazing initially but after 1st and 2nd year when we had problems with top layer chipping and flaking off he wouldn’t answer our calls, texts, or Facebook messages. He was nowhere to be found!!!!!! VERY UNPROFESSIONAL Alls we wanted was ideas how to fix and how to prevent and most importantly the color release he used so we could fix the all the chipped spots. It just looks terrible 2 YEARS LATER!!!!! We had 2 different professional come look at the chipped sides and flaking and tell us same thing that it was negligence….air trapping too much air in concrete release being hand tossed etc…and the chipping from edges not being rounded bullnosed like it’s suppose to be!! This worker is known by rest of concrete world and previous customers for his bad workmanship. I wish we would have known this before!!!
Provencher Flatworks is a professionally run company. Very knowledgable and quality work.
100% Quality at its best !!! If you are looking for a professional concrete company then give Provencher's a call, some of the best concrete pros in the industry
