Robert and his apprentice Lazar were absolutely amazing. They did a super job and painted my apartment in record time. Highly professional, he takes pride in his work and extremely respectful of both myself and my apartment. I would give them more than 5* if I could. They will be recommended to all my family and friends for sure. Thank you Robert and Lazar.
Robert and his team were a pleasure to work with. He was professional, communicative, and thorough throughout my project. From the start, he carefully assessed what was needed, provided a clear and detailed quote, and sourced all necessary materials—including a perfect match for some flooring that needed replacement, which I greatly appreciated. While working in my home, Robert was meticulous and respectful. He kept the space tidy, used drop cloths to protect surfaces, and was as mindful of noise as possible while I was home. The finished result looks fantastic, and he even went above and beyond by helping me lift and move a few small items. I wouldn’t hesitate to work with Robert again and highly recommend him and his team for any renovation project.
Working alongside Robert and the entire team at RM Renovation was a pleasure. As rookies in major home renovations, they skillfully navigated us through the process. Opting for RM Renovation for our full basement overhaul was the right choice. Given our home's age of 50 years, surprises lurked behind the walls, yet each was met with professionalism and swift resolution. Throughout the 4-month renovation period, subcontractors and tradespeople seamlessly managed their tasks, showcasing their expertise and efficiency. Delighted with the final outcome, we eagerly anticipate working with RM Renovation on future projects and wholeheartedly recommend their services!
Robert conducted himself with utmost professionalism and was approachable. I communicated my desires and specifications, including the timeframe, and was pleasantly surprised by the outcome. Thanks to RM Renovation, my dream home became a reality.
Robert did a large reno on my home; we had work done on all 3 floors, including a new kitchen, new bathroom, and new floors through most of the house. He worked well with us when we added to the project and made changes when we asked. He finished on time and on budget
Very professional and clean work Will definitely work with them again
They are quick, efficient and personable, we look forward to continuing our working relationship.
Friendly staff pleased with quality of work
