"I cannot speak highly enough about our experience with New Key Construction. If you're looking for the cheapest option, this may not be it but if you value exceptional craftsmanship, thoughtful design, and absolute reliability, look no further. From the very first meeting, their team brought a level of professionalism and vision that immediately set them apart. They took the time to understand our goals, suggested design improvements we hadnt even considered, and executed everything with incredible attention to detail. The end result was not just a finished project it was a space that reflects quality, style, and lasting value."

"We hired New Key Construction to renovate the interior of our most historic 1850 construction Masonic Building in California. Their entire staff, from Reggie the owner to Connor foreman to Elle project manager are professional and great to work with. Elles attention to details during every step of the project yielded a beautiful outcome, and rendered the project a huge success. The building will be featured in one of our upcoming quarterly magazines, and we are delighted to showcase it, post renovations."

"We worked with New Key Construction to remodel our backyard workshop and transform it into a 1 bedroom, 1 bathroom ADU for my parents to retire and live in. New Key did an absolute outstanding job and we are so happy we chose them for one of the largest investments we've ever made. - Quality Work - Reggie and his team do quality work; they do not cut corners, and they will always lean to do things the right way that is safe, compliant, and functional. You can feel the quality when you walk around; there is a meticulousness to the work that is hard to find anywhere else. - Project Planning - We were assigned a project manager and a foreman who kept us updated very frequently on the state of construction. The work was completed on-time if you account for the realities of construction which were largely due to supply delays andor the occasional coordinate of some competing work. To convert a workshop where we literally stripped it down to a livable, high-quality ADU in 5 months is impressive! Also, they showed up on-time every day and if they were going to be late or not come, we would be told. - Culture - Everyone that works at New Key Construction was a pleasure to work with; they hire people who care about the work they are doing and make an effort to get to know you. We could tell the employees enjoyed working at New Key, and it shows in the work. We looked at several companies before choosing New Key. I wholeheartedly will say it was worth it - you get quality work, quality communication, a 10-year warranty, and people who legitimately care about you and your home. You won't regret it!"

"After researching and interviewing several local contractors in the Pleasant Hill area, we chose to work with Reggie and the New Key Construction team to complete our kitchen remodel and update the flooring in the main areas of our house. From the start, Reggie was responsive and thoughtful in his approach to our scope of work and dedicated a lot of time to thoroughly review our wishlist, budget, and timeline as the project took shape. He was open, honest and realistic in every conversation and made us feel comfortable and ready for the work ahead. Elle was our Project Manager and did a terrific job organizing the build schedule and juggling all of the moving pieces from start to finish. Even with covid-related material delays, she pushed hard to keep our project on track and stayed in constant contact with all of the vendors and contractors involved. She was quick to flag any issues that came up, explore solutions when needed, and took the time to make sure we were happy as the project progressed. She and Reggie were receptive to feedback and accountable when issues arose fortunately, all were relatively minor. It is evident that the New Key Construction team has a great working relationship with their subcontractors. All of the subs were friendly, timely, clean, and produced high-quality work. Having lived in the house while the work was completed, we could see first-hand that no corners were cut and nothing was overlooked! As an added bonus, they utilize the Buildertrend platform, which made it easy to track our finances, view when specific work was scheduled, and stay aligned on change orders. It is obvious that Reggie and New Key take pride in their work and truly want whats best for their clients. We had a great experience and love our new kitchen and floors!"

"I bought an older home in Concord and moved in only to discover, during an easy re-flooring project with New Key Construction, that the old owner improperly installed appliances when I purchased that led to months and months of water damage in my kitchen! I was panicked - we had already spent a lot of money on the house and now we were looking at extensive water damage and mold in two major rooms of our home. Reggie and his team helped me every step of the way. Because we were already working together on my flooring project, I didn't event think about calling anyone else. Reggie helped me coordinate with my insurance company and get the coverage I deserved, and what could have been money out of pocket, got covered and helped me totally rebuild my kitchen where the water damage was into a gourmet MASTERPIECE. This kitchen was so outdated when I moved in - I hated it. Now, it's my favorite room in the house and it raised the overall value of my home so much. Reggie and the team also helped me update my bathroom as well as my master closet a custom job. After pics posted here. If you're looking for an honest contractor to help you remodel your home, I strongly recommend Reggie and New Key Construction."
