Woolsey Construction Reviews

"Woolsey built an ADU in our backyard and the experience exceeded expectations from start to finish. Taking on a construction project at home can be stressful, but their team made the entire process feel organized and under control. From the initial planning stages through completion, communication was clear and consistent. They set realistic expectations, stuck to their commitments, and were proactive whenever questions or decisions came up. What really stood out was how well they managed both the schedule and the budget. They finished earlier than projected and came in very close to the original budget, which is rare in this industry. The quality of the workmanship is excellent. The finishes, attention to detail, and overall execution reflect a team that takes pride in what they build. Inspectors, neighbors, and friends who have seen the ADU have all commented on how well it turned out. Beyond the construction itself, Woolsey was simply easy to work with. Professional, responsive, and solution oriented. If you are thinking about building an ADU or doing a significant home project, I would strongly recommend Woolsey. I would not hesitate to work with them again."

"We give Woolsey Construction the highest recommendation. They are truly the gold standard of construction companies. Weve worked with others in the past and our Woolsey team was in an entirely different league they are top tier in quality, professionalism and ability to successfully solve problems. They bring the best combination of expertise, quality of work and clear communication. They were able to accomplish projects that other companies and G.C.s said were completely "impossible." Our project seemed straight-forward a townhome remodel but was fraught with repeated issues, including structural water leaks, inoperable ducting and multiple other fundamental problems related to the faulty original 2006 build by a different builder. Our project lead, Aaron Rawls, was superb, and approached each issue with a positive, can-do attitude. Aaron told us during one particularly difficult moment; "there are no problems, only solutions," and this was certainly his creed. Aaron and the entire Woolsey team were always able to find solutions for us. They turned what could have been a terribly stressful project into a series of pivots and solutions resulting in our beautiful, dream home. We are very grateful to Aaron, Robert, Luke, Jessica and the whole amazing team at Woolsey for making our remodel a positive experience, exceeding all expectations!"

"We recently had our 1,200-square-foot home renovated by Woolsey Construction and we couldnt be happier with the results. If you know small, Clairemont homes - then you can picture what ours looked like "before." Essentially, they completely transformed our kitchen and main bathroom, turning our once cramped spaces into bright, open, and beautifully functional rooms. The new kitchen is everything we hoped for airy and full of natural light, with a gorgeous 9-foot island thats become the heart of our home. It feels spacious and welcoming, perfect for family gatherings and everyday life. The bathroom renovation was especially meaningful to us. Woolsey worked closely with us to make it fully accessible for our young daughter, who uses a wheelchair. Their team paid thoughtful attention to every detail, from layout and materials to safety and ease of use. The result is both practical and beautiful were so grateful for their care and craftsmanship. Some things I feel are worth mentioning: we, the homeowners, were very strict about our budget and also didn't have a particular design or aesthetic in mind - we simply wanted to stay on track with our money. This was our first time ever undergoing a renovation and we were very nervous about the cost and the length of time to get it done. Due to this, we often selected rather boring design elements that we felt were good choices because they fit the budget. An example of this was when we chose some pretty basic subway tiling for the bathroom, which was being transformed into a big, bright, open room with a giant roll-in shower. Aaron, our construction lead, gently suggested as an alternative to our tile choices, a striking patterned design for the floors and walls, which really elevated the very practical bathroom into a spa-like space. In fact, I often deferred to Aaron about design choices, figuring with his experience and eye for detail, he would not go wrong in presenting options that were both functional and beautiful. I truly appreciated his insight and attention to detail during a stressful time. I could not be happier with the results of our renovation and I have learned a lot from the team about design, budgeting, timelines and expecations, which will serve me well in our next reno project. Throughout the entire process, communication was clear, the team was professional and respectful, and the work was completed in record time. Shout outs to Robert, Jon and definitely Aaron, who were responsive, friendly and understanding throughout the process. We liked working with Woolsey so much, and the results of the reno, that we are working with them to build an ADU in our backyard. Woolsey features incredible transformations and new builds on their social media and do amazing work, but even for someone with a modest budget and limited timeline like me, they took dated, dark and dingy rooms and transformed them into bright, airy, highly functional and stylish spaces. I recommend Woolsey Construction wholeheartedly and without reservation to anyone looking for quality workmanship and a team that truly listens to your needs. Looking forward to the next project. Thanks, Woolsey team!"

"Woolsey Construction recently completed a room addition for our home, and we couldnt be happier with the result. In an industry where its common to run into flaky or unresponsive contractors, Woolsey stands out in the best way possible. Their communication was top-notch from start to finish, and they really went the extra mile to make sure we were satisfied every step of the way. The project was completed on time, just as they originally estimated. And the quality of the work was exceptional. Of course, no project goes 100 smoothly, but what really impressed me was how they handled the bumps along the way. When issues came up, the team tackled them head-on with a can-do attitude and a real commitment to making things right. I would highly recommend Woolsey Construction to anyone looking for a contractor they can trust. These guys are going places, and Ill be supporting and referring them every chance I get."
