Our services in Alameda:

  • Crawl Space Encapsulation System: A complete sealing system using the CleanSpace® 20-mil vapor barrier to line the floors and walls of your crawl space. This barrier blocks moisture and outside air, reducing mold, wood rot, and musty odors while improving energy efficiency. Backed by a 25-year transferable warranty.
  • Sump Pump Installation: Professional installation of sump pump systems like SmartSump™ and UltraSump®, complete with airtight lids, water alarms, and battery backups. These systems actively remove water before it can cause damage, and are often paired with perimeter drainage for added protection.
  • Dehumidifier & Humidity Control: High-performance dehumidifiers like the SaniDry Sedona are designed specifically for crawl spaces. These systems keep humidity in check to stop mold, improve air quality, and maintain a dry environment beneath your home.
  • Structural Support Jacks: SmartJack® crawl space support posts are steel piers anchored into stable soil to lift and support sagging beams and joists. These adjustable jacks provide long-term stabilization and help restore uneven floors.
  • Crawl Space Insulation: Closed-cell, moisture-resistant insulation including SilverGlo™ wall panels and TerraBlock™ floor insulation. These materials resist mold, improve energy efficiency, and are designed to withstand crawl space conditions.
  • Mold Treatment & Cleanup: Safe application of Mold-X2 products to treat surface mold and prevent it from returning. This treatment is part of a complete system that includes moisture control to ensure long-lasting results.
  • Crawl Space Drainage Systems: Interior drainage channels or trench drains direct groundwater toward the sump pump. These systems are crucial for preventing flooding and are customized to each crawl space’s layout and water conditions.
  • Air Purifiers: Optional air purification systems improve the air flowing into your home from the crawl space. These systems help remove allergens, mold spores, and odors to create a healthier indoor environment.

We are having high humidity throughout the house and believe the very moist crawlspace is partially to blame. We are curious about either installing a vapor barrier or encapsulating it.

Hi, I am interested in a moisture barrier for our crawl space. Our home is 1392 square feet, built 1959, and I have some photos of the crawl space if useful, because we recently completed a brace & bolt project. What is the next step for getting a quote? Thank you, Adam

Water in crawl space and garage from rain
Project Location: Alameda, CA
I recently inspected my crawl space under my house and noticed that there is something growing that looks like it might be mold or mildew on the wood pieces under the house. It is unclear where the issue is coming from since the soil under the house is usually quite dry in Alameda and I also installed a homemade Moisture Vapor barrier last year. I don't see any actively leaking pipes or drains that could be contributing to the moisture. It is possible it may be from the rain we had last winter when we had a leak in the rook and the mold just keeps propagating. Would love to get someone out to take a look at what might be causing the issue and to get rid of it.

I have a dirt floor crawl space of roughly 600 sq ft in half of the basement of my single family home. We would like an estimate for crawl space encapsulation or vapor barrier for this space, as well as addressing any issues leading to the moisture that may need to be addressed as prep work before the barrier can be installed.

We are moving into a new house soon, but found quite a bit of rodent droppings in the small, unfinished basement + crawl space area. Approximately how much would it cost to get this cleaned out?
