Mill Valley sits at the base of Mt. Tamalpais, and the same fog and canyon shade that keep the redwoods alive keep the humidity up inside a lot of houses here. Wood floors feel that. We see more seasonal movement in Mill Valley than almost anywhere else we work, boards that tighten up in September and open a little by March.
The housing stock is largely older, craftsman and cottage-style homes on raised foundations with crawl spaces underneath. That is usually good news, because it means real solid oak or fir under whatever is on top, and solid wood can be sanded and brought back several times over. It also means the crawl space is worth a look. A damp one under an otherwise healthy floor is the most common reason we get called back to a Mill Valley house a second time.
If your floors are original and just tired, refinishing is usually where we would start. Call today for a free estimate.
