RWR has done a lot of work in the Mill Valley area, including foundation repairs, retaining walls and drainage repairs. The hilly Mill Valley area, at the foot of Mt Tamalpais gets a lot of rain and moisture, which can cause foundations to become unstable, and retaining walls to fail. It is important to correct these problems with well designed, well engineered plans, that are properly constructed. RWR specializes in this type of construction work in the Mill Valley area, and has great relationships with many engineers and architects working in this area.  If you have a situation you’d like us to look at, please give us a call.
