"This is an overdue review. I hired Bernie and his team for a kitchen remodel in June 2021, after he did an excellent job with my three bathrooms in 2020. The kitchen remodel was also excellent. His works are efficient, hardworking and clean. My remodel took two weeks, as he had quoted and for the exact price he had quoted. I would hire him and his team again and I referred them to a coworker for her bathroom project. She was also very pleased with their work."

"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"The company represented to be competent and experienced at bathroom remodeling however the worker, Joel was not able to complete the job efficiently. He installed a shower liner over a shower body which he had improperly installed which caused leaks and a situation where we had to break through a wall to get to the improperly installed shower body to fix it. We supplied the materials including the shower body which he did not use but instead left the old one in which doesn’t quite fit with the new shower handle. The toilet was loose and crooked also not sealed on the bottom as per code. When I pointed out to the worker that he had caused a leak, water was pouring into my basement he attempted to charge me an additional $100 to fix his own mistake. The tiles were not properly spaced so some were too close to receive the black grout that we had intended to distribute over the whole tiling project, it remains unevenly grouted. With the uneven spacing it is impossible to grout properly. Overall a disaster of a job, most of the work he did had to be redone."
