Maintaining a San Francisco Victorian: Wood, Water, and a Century of Layers

Wood Is the System

Redwood frames endure when kept painted and dry. The maintenance religion: paint cycles honored, horizontal surfaces flashed, and every gap caulked before the rains. Deferred paint on a Victorian is deferred structure.

Dry Rot: Find It Early

Probe annually at sills, brackets, stair stringers, and bay-window bottoms. Fog-belt neighborhoods (Sunset, Richmond) run damper than Mission sun pockets — calibrate vigilance to your micro-climate. Small epoxy repairs beat carpentry rebuilds.

The Layers Below

Brick foundations on older stock, post-and-pier sections, and the seismic question: bolting and shear work where not yet done is the city's best-value structural investment. Check the crawlspace each spring — moisture, debris piles, and pest entries.

Systems in Old Walls

Knob-and-tube remnants (insurers ask), galvanized supply lines, and original waste stacks — plan replacements with any renovation rather than as emergencies.
