After washing, scraping, and sanding your wood siding, step back and inspect what you’ve uncovered—holes, dings, and chips.

Fill minor holes or dings in the siding with a patching putty or compound such as Zinsser’s Ready Patch ($20 per gallon).

If you’ve got a major rot problem, summon a carpenter to replace the bad wood. Also, fix drainage problems that cause water to pool and promote rot.
