Warped or buckled hardwood floor — San Francisco, California
Warped or buckled hardwood floors are typically caused by moisture imbalance — either a water leak underneath, high humidity, or improper installation without adequate expansion gaps. Individual boards may cup, crown, or lift away from the subfloor. A carpenter or flooring specialist can assess the moisture source, repair or replace affected boards, and re-sand and refinish the area.
Why this is common in San Francisco
Salt air and persistent fog drive chronic dry rot in the ornate exterior woodwork of SF's Victorians and Edwardians, demanding skilled restoration. The mandatory soft-story seismic retrofit ordinance generates substantial framing and structural carpentry work across older multi-unit buildings.
