Wet crawl space
Project Location: San Ramon, CA
Went under the house a few months ago to repair a kitchen drain pipe and then went under today to install 1/4" mesh screen to seal openings where the pool installers years ago had not done a good job of repairing vent mesh to keep out rodents. Hate going under there because there is 30 years of mice/rat feces accumulated. Need crawl space cleaned and new vapor barrier installed.
