Our services in Danville:

  • 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 Danville, CA
Crawlspace Encapsulated System

Mark M. reached out to Clean Crawlspace because he was getting a musty odor that emits from the crawl space when it gets wet during the rainy seasons. He passed by one of the trucks and realized they were the company for him. He called the number on the truck and was able to get an appointment just a few days later.

The inspector came out to his home and recommended the encapsulated Cleanspace liner. This encapsulation system is a completely sealed 20 mil liner that would prevent any odors from the soil from getting into his home. This liner will also protect his home from any potential moisture damage.

Mark M. now gets to enjoy his home with no unwanted odors creeping in for many years to come. He also doesn't have to worry about the upcoming rainy seasons.

My crawlspace has a moldy smell to it but looks dry.
Project Location: Danville, CA
We have three crawl spaces, each with an encapsulation liner. We also have two sump pumps - but each crawl space is vented. I was curious about the cost and benefits of converting to an unvented crawlspace to see if it is something we should do here. If we do want to stay vented then we at a minimum need the sump pumps servicing/replacing as appropriate, and water alarms being added/replaced as well as patching the liner in some areas. Thanks!

We are in a low area with heavy ground water saturation. We usually get seepage into our crawl space. I have a sump pump and air mover, but would really appreciate sealing the crawlspace to prevent the winter musty smells that come from below.
