Project Location: Oakland, CA
I want to put down a vapor barrier over dirt floor in crawl space under garage (about 15 feet by 26 feet). Plus add insulation in the basement and crawlspace. I believe cold and dirty air is leaking into the house from the basement. I had the loft insulated recently but the house is still cold.
Project Location: Oakland, CA
I believe I have mold growing in my crawl space. It is not encapsulated, vented crawlspace with bare dirt ground. Would be interested in installing a 10mil vapor barrier as a moisture retarder and doing some mold remediation down there to to stop the spread, and get a general opinion on the space. Would like to avoid total encapsulation. Thank you for your time

Damp crawlspace with high water table and sometimes standing water.
Project Location: Oakland, CA
Hi! We bought our home last year. The lower levels have been cold all winter. I think it's due to a combo of old windows and a lack of insulation in the crawl space under the home. The crawl space has some vents on the side, a dirt floor, and only minimal insulation around the ductwork. Separately, we have an awkward attic space that the previous owners turned into a loft. I think there may be some heat leakage there too.
