Your business was a recommendation from our oldest daughter who recommended you to her sister and then us. We are a complete family that you have serviced. Everyone is extremely satisfied.

Jean C. Jean C. Seawood Way

Our experience with Clean CrawlSpace has been absolutely OUTSTANDING. We had our crawlspace encapsulated with sump pumps never anticipating how much we really needed them. We live in the Almaden area of San Jose and have heard there were springs in the area. Our solid oak hardwood floors were recently installed by a Diamond Certified company. They informed us that our moisture reading was borderline and would be solved by a vapor barrier. However 6 months later we noticed the floors had a slight cuping. No one has ever recognized that we had any water but there was an odor. Since completion of your work we are aware of the amount of sub surface water in our crawlspace. Access to the crawlspace is in the interior of our house. Your employees made sure their work was done with no impaction to us. There was no tracking of debris. They were very efficient and professional. Thank you for a job well done.

Would like advice on closing up the existing crawlspace air vents. A lot of debris enter into the nice clean crawl space; not certain if I need air circulation as a building code or possible attempt to change this region into a conditioned space by installing air duct / ducts to provide heat

There was some lack of communication between Alex and David about where the pump should drain in the yard, and there were some questions for me that I wasn't sure how to answer.

Job Stories From Santa Clara, CA

Santa Clara, California, Crawlspace Gets a Professional Rescue!

David G.'s dream home in Santa Clara, CA, became a source of worry thanks to a poorly installed sump pump. The inexpensive solution from a general contractor ended up backfiring - the sump pump died quickly, and without a check valve, household water flowed back into the crawlspace, creating a soggy mess. Yuck!

Concerned about the growing moisture and potential mold problems, David called in the trusted crawlspace experts at Clean Crawlspace. They installed a SmartSump pump, ensuring continuous dryness, and fully encapsulated the crawlspace with CleanSpace Vapor Barrier, an airtight vapor barrier that keeps moisture out. Now, David can finally relax knowing his beautiful home is protected.
