Care for traditional wood siding
Wood siding lasts best when finish, end grain, joints and drainage are maintained before prolonged wetting causes decay.
Recommended timingInspect every spring; clean and refinish as needed
What to do
- Inspect paint or stain, board ends, joints, fasteners and lower edges for peeling, open checks, loose boards, softness or insect activity.
- Clean dirt gently with water, mild non-phosphate detergent and a nonmetal brush, following the finish manufacturer's instructions.
- Keep gutters working and sprinklers, soil, mulch, snow and vegetation from repeatedly wetting the siding.
- Repair water entry and deteriorated wood before refinishing; use a coating compatible with the species, existing finish and exposure.
- Preserve ventilation and drainage details rather than sealing every visible opening indiscriminately.
