Omri at Green Works was great to deal with on our renovation service. He always returned calls and kept me informed in every step of the process. The crew was extremely hard working and the price is fair. I will definitely recommend to others!!
Used this company for a full kitchen and bathroom remodel. From our first meeting with Raz, the experience was great—he helped design everything within our budget. The project stayed on time, and any issues were handled quickly. The final result came out beautifully, exactly as we envisioned.
We hired Green Works Construction to renovate a few areas of our home and they did a fantastic job. What stood out most was how professional and calm they were throughout the entire project. Even when small issues came up, they handled them quickly and without stress. The final results look great and the craftsmanship is excellent
Save yourself the trouble and do not use GreenWorks. They redid our kitchen a couple years ago back, but in less than a year the paint on the cabinets was chipping off like crazy and even in spots that were not heavily trafficked. They came out to repaint only to open up more nightmares. After the repainting of the chipped cabinets, the repainted cabinets were different colors. GreenWorks stated that it would dry fine. It never did. So they came back out to repaint all cabinets. But their work was so careless that we have green paint sprayed on our walls and floors and the cabinets in some places don’t shut nicely because of the thick paint on it. Oh and they cut our countertop slab crooked… So where it meets the range that we have it is not an even space. They also dented our range hood. Overall, extremely low quality work. If you would like your cabinets to chip in less than a year and have a company that doesn’t hold themselves accountable… then choose GreenWorks. If you want a kitchen to last more than a year, look elsewhere.
This was by far the best renovation project I have even gone through. Tomet was fantastic as our liaison and project manager which made the process go very smoothly. The communication, skill, follow through, respect of the workers, cleanliness and overall experience was an A+ in my book. We will be scheduling our kitchen renovation ASAP.
