This home has a unique story. This home had a liner and sump pump installed in 1977! It has been doing its job for many, many years. But unfortunately, the technology was not very good back then and things don't last forever. After the homeowner noticed that the sump pump bucket was full of water he started investigating. They found it had stopped working and he was pretty sure the discharge line was gummed up. They had a lot of standing water in the crawl space from this and they started to notice a moist, musty smell in their home. They went on Home Advisor and started searching for crawl space experts. They came to find us at Clean CrawlSpace Inc. We got there old, non-working sump pump system out and put in a new one that will last them for many, many more years to come!

  • 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.

Recently purchased a home (1989 build) and some moisture/smell was noticed when the crawl space was opened. After a visual inspection the insulation looks old and seems to be blocking some air vents to the exterior of the house. Would like to get an estimate and evaluation of what may be causing the moisture/odor and corrective actions. Thank you.
