"I hired Topaz Remodeling to replace my front porch, including tearing out the damaged surface, installing a proper drain (the original builder’s oversight caused major leaks), and repairing the resulting damage to the floor, hardwood, and basement. The owner’s communication was excellent, keeping me informed about schedules and progress. They even finished ahead of the estimated timeline. Omar, the project lead, was phenomenal. His recommendations elevated the final result, and his attention to detail was unmatched. The tilework is flawless, with precise measurements ensuring a polished look. The team delivered exceptional quality, turning a stressful situation into a seamless process. My new porch is beautiful and fully functional. I highly recommend Topaz Remodeling and will gladly use them again for future projects."

"The whole experience was excellent. Chris when to give us a bid. He was very knowledgeable. He told use about the triangle of stove, fridge and sink and flow. He suggested a long narrow window to replace the tile backsplash on an outside wall. It was a great idea. When sit at the new bar between the kitchen and the living room we look out into our backyard. Itâ s beautiful. The guys that did the work are extremely work oriented. They are constantly working. They were thorough, knowledgeable and open to our suggestions and requests. We wanted an additional can light no problem. They were great. They cleaned up every day before they left. They would tell use when they were going to arrive and what they planned to accomplish that day. I have old siding on the outside of my house. They matched it perfectly when eliminated a window. The price of the cabinets was a lot more reasonable the other bids and theyâ re beautiful. What I mentally pictured in my mind on how it would look and the ease of preparing meals in the new kitchen were so wrong. Itâ s at least 10 times better. It still has the same physical dimensions but how itâ s played out. It seems so much bigger. I highly recommend them for any project you need done"
