We've use Leimer for several projects and have been really happy with their quality of work – plus the whole team is super nice. We had a large deck done, a shed built, and an entire bathroom remodel too. I'd highly recommend John and his team.

John and his crew recently completed a remodel of our outdated kitchen in Mill Valley to our complete satisfaction. After interviewing half a dozen contractors, we chose John because of his strong references, trust-inspiring personal style, competence and availability at the desired time.

The project involved removing and replacing cabinets, counters, backsplash, appliances, painting, plumbing, windows and refinishing floors with more contemporary materials. John is very organized and efficient and is a great communicator. Happily, his team finished the project in 3 months, with little to no lags in between. They went out of their way to be accommodating and considerate, and followed through with every detail up to the very end. We have such a high regard for John and his right-hand man, Brad, whose professionalism, expertise, perfectionism, responsiveness and thoughtfulness surpassed our expectations; in fact, all the subs were terrific. We really enjoyed working with them; they actually made our remodel a pleasant experience. Thanks to John and his team, our kitchen transformed into a beautiful, contemporary gathering place. I highly recommend Leimer Construction!

We used Leimer Construction for a three floor home remodel and were very impressed with the craftsmanship, integrity and professionalism of John Leimer and the skilled trades he utilizes. His Foreman named Scott worked on difficult structural elements of our house, and he is a master carpenter who is very detailed yet works efficiently.
