Gathering quotes for crawl space vapor barrier installation to help mitigate a musty smell we are getting inside our home
Project Location: Gilroy, CA
Old duct work and insulation in crawl space. Sump Pump has stopped working and we now have a musty smell in the house during the winter.
Project Location: Gilroy, CA
We are helping a client with a vapor intrusion concern and one of the remedies suggested is either sealing the floor and/or installing crawl space ventilation. The crawl space only covers a portion of the building so we may need to do a combination of remedies. We don't currently have contractors in this area as we primarily work on the east coast and in the Sacramento region. Please let me know if this is a service you would be able to provide.

Received pest report that there was a lot of moisture under our home and there are signs of having standing water. Want to have this assessed for repairs.
Project Location: Gilroy, CA
We recently had an inspection for pest and house was tented. It was mentioned that there was moisture below the house and new moisture barrier may be needed. Wanted a 2nd opinion.

Options for encapsulation
Project Location: Gilroy, CA
Standing water arises in crawlspace periodically during rainy season, needs mitigation. Unsure of exact source but seems to only rise to standing water levels during rainy season, when it can get up to several standing inches at times. Seems to drain gradually over several weeks of no rain but stays at least somewhat damp year-round.

Price on installing moisture barrier in crawl space
Project Location: Gilroy, CA
Standing water under house due to high water table. Have pumps at most downspouts but with the water table any rain does not penetrate deep into the ground and becomes water under the house crawl space. Probably need sump pumps and moisture barrier since we are selling the house.
Project Location: Gilroy, CA
I had a hot-water line break and flood the crawl space... the water has seeped into the dirt floor and I'm not running fans and dehumidifier to pull moisture out. I would like to get a quote on securing the entire crawl space with a barrier (floor & walls).
