Our services in Sebastopol:

  • 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 just took out all the fiberglass insulation in our crawlspace and there was some water seeping in on the left side of our house and some mold on the ground in the crawlspace. We would like better air quality in our house and to not breath in so much mold from the crawlspace. Do not want water going in the crawlspace and looking in to potentially encapsulating the crawlspace. Thanks

1850 sq ft crawl space, interested in clean up and vapor barrier or encapsulation.
Project Location: Sebastopol, CA
Home seems to have small crawlspace with poor ground drainage and downspout drainage around foundation. 1930's home. Musty smell. Looking to divert water around foundation and away from home as well as insure clean dry crawlspace to prevent mold and sitting water.
Project Location: Sebastopol, CA
Needing a vapor barrier attached 'under the flooring' of the house. I've installed a 20mil vapor barrier on the ground below. Needing the extra insulation. The house is 1600 sq ft. with most of the 'under-floor' area exposed with only fiber glass insulation also exposed. House sits on a slant, there is easy access to most areas. Tighter crawl space area only at top of ground slant.
