CRAWL SPACE SUMP PUMPS
PORTLAND OR – VANCOUVER, CAMAS & LONGVIEW WA
Water in the crawl space of a home can be alarming and for good reason. Depending upon the amount of water present, as well as the length of time it is allowed to remain there, the damages can be extensive and the cost of crawl space water mitigation can be expensive.
In addition to the weakening and deterioration that constant dampness can cause to the home’s structure, the problem of mold can also become severe. Mold spores thrive and flourish in damp, dark areas which makes watery crawl spaces the perfect location for them. The growing mold can spread to floor joists, ductwork, and other hard surfaces.
Additionally, mold will also grow on areas considered to be “soft” such as the plastic vapor barrier and fiberglass insulation. Once mold has invaded fiberglass insulation, it must be removed and replaced.
Determine Where The Water Is Coming From
Determining the source of the water is important. If the water is present year-round, regardless of whether in varying degrees, the problem may lie within the home’s plumbing.
Leaking pipes from showers, dishwashers, and washing machines can cause water to accumulate in a home’s crawl space. If this is the source of the problem, repairing the faulty plumbing should clear up the problem.
If the water is coming from an external source, such as an underground spring or frequent flooding from excess rain, then the crawl space water mitigation becomes a lengthier process that may require the services of a company specializing in water mitigation services.
What are Water Mitigation Services?
Not to be confused with companies that provide basement drying and restoration, water mitigation service companies work to remove the water and then fix the problem to help ensure that it does not recur in the future.
The overall strategy is to define a parameter around the crawl space, then capture and redirect water that tries to cross the parameter into the crawl space. Crawl space sump pumps are then installed to siphon the water and pump it away from the space.

Can I Mitigate My Own Crawl Space Water?
It is possible for a homeowner to take this task to hand, but a word of caution is in order. This is not a job for the weak or inexperienced in home repairs. It requires intensive physical labor. Plus, crawl spaces are usually short in stature, making the work even more difficult.
Before installation of crawl space sump pumps can be completed, a GFCI outlet must be installed. This can only be done by a licensed electrician.
If the crawl space has a plastic vapor barrier in place, it must be removed and discarded. Then the barrier parameter must be created by digging a trench from 8 inches to 24 inches away from the foundation around the crawl space.
Once the trench is dug, 3″ sock flex perforated pipe should be laid within the entire length of the trench, and then covered with drain rock to a depth of an inch and a half. Use the dirt that was dug out in making the trench to spread around the interior of the crawl space.
When the proper GFCI outlet has been installed, the crawl space sump pumps can be installed to discharge water that collects in the trenches.
Finally, a 6 mil vapor barrier must be installed to block vapor transfer from gaining access to the crawl space.
Consider Calling In Professionals
Water mitigation in a crawl space can be exhausting, backbreaking work that must be done correctly in order to solve the problem. While using professional water mitigation professionals for the job can be expensive, attempting a job of this magnitude by laypersons can create problems that may be more expensive in the long run.
