Our services in San Rafael:

  • 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.

Mold and moisture issues.

Hi! We're looking for someone to assess what we need to do re: drainage and mold prevention, and also provide an estimate for the work. Our house is a slab foundation (no crawl space) in a flood zone, and we want to have peace of mind when it rains, etc. We are new homeowners so we want a professional opinion on what we should do to protect our home.

I had the moisture layer and insulation ripped out from under my house 4 years ago due to a rat infestation. I am concerned about moisture under my house due to some floor boards buckling in my living room.

Recently had a leak that resulted in some of the existing moisture barrier being removed. Leak has been fixed, now need vapor barrier restored.
Project Location: San Rafael, CA
I just purchased this home recently. It has a TON of crawlspace, which is amazing. However, it's quite dirty which makes it inconvenient to work in. I've seen photos on your website of the barriers you install, which I think would make my crawlspaces much nicer. Additionally, the crawlspace has previously had mice. We think that has mostly been resolved with another company (Alley Cat), but having you seal off any remaining entry points you find could help.
