Our services in Fairfield:

  • 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.

Job Stories From Fairfield, CA
Mold fix in Fairfield, CA

David C, of Fairfield CA, had a moldy, wet, dirt crawl space that was causing his home and his family's health to suffer. He first noticed his home starting to smell moldy and damp. He took one look into his crawl space and realized it was full of mold and moisture with clear signs that the crawl space floods when it rains.

He decided to reach out to us at Clean CrawlSpace Inc, and we were able to send out our mold and crawl space specialist. Our sales rep made a plan to seal the crawl space from the moldy, wet dirt, with the fantastic CleanSpace Encapsulation system and to fully clean and sanitize any mold found in the crawl space. Then to prevent any water that enters the crawl space He devised a plan to dig trenching to divert water to one area and installed a sump pump in that area to pump away any water from the crawl space. 

Our crews came out and performed the work, and now David C can rest easy knowing his home and his health is protected from any dangers that can come from dirt crawl spaces!
