Hello, I would like to get an estimate for installing a crawlspace vapor barrier. Thanks.

Crawl space is damp and smells musty
Project Location: Menlo Park, CA
I am currently under contract to purchase a house, and the home inspection has revealed efflorescence in the crawl space, as well as a missing vapor barrier. It recommends improving ventilation within the crawl space area for better maintenance. I was told that a proper design solution should be discussed to address ventilation and drainage improvements in the crawl space.

Water in crawl space
Project Location: Menlo Park, CA
We are considering buying a property. The inspector found some moistness in the crawl space and hence would like get a professional opinion on the crawl space both from mold/growth issues, any mitigations for the future in terms of ventilation and also understand impact to the structure because of the wetness caused esp by recent rains

We had Bear Engineering out to look at a basement leak and they recommended that we have a sump pump installed as well as have the waterproof liner on the uphill side of the basement potentially replaced.

Need a quote for cleaning crawl space
Project Location: Menlo Park, CA
Water pooling in crawl space. This is an old house and probably needs work to install a proper drainage system. There are sump pumps installed but unclear if they are working/draining properly.
Project Location: Menlo Park, CA
I am interested in crawl space insulation
Project Location: Menlo Park, CA
We are remodeling and noticed a smell from the crawl space. We know there have been moisture problems in the past. We think there are still moisture problems. We have relatively easy access now due to the remodeling so it is a good time to address the problem. I think sealing the crawl space would be a good idea and want to learn more. The crawl space sits under a 2 story home that is ~3000 square feet. So, the crawl space should be ~1500 square feet.
