Serving Longview, Kelso & SW Washington
Crawl Space Drain Systems for Standing Water Under Your Home
If water collects in your crawl space after heavy rain, a drain system can collect it and move it out. We find where the water is coming from first, then design a drainage plan for your crawl space in Longview, Kelso and nearby.
- We trace where water gets in and where it collects
- Drain lines planned around your crawl space's layout
- Paired with a sump pump when water has to be pumped out

Common signs
Signs your crawl space has a drainage problem
Standing water or puddles
Water you can see sitting on the ground or plastic under the house.
Water that comes back after rain
It dries out for a while, then returns with the next big storm.
Mud that never dries
Soil that stays wet or soft even in drier months.
Water on top of the plastic
An old barrier can trap water on top instead of letting it go anywhere.
Water lines or stains
Marks on foundation walls, piers or posts showing how high water has been.
Wet insulation or framing
Moisture that's working its way up into the materials above the ground.
Some water problems start outside, with gutters, downspouts or grading. If that's part of the cause, we'll tell you.
How it helps
How a crawl space drain system works
A drain system gives water a planned path out. Drain lines are placed where water collects, often along the foundation or through low areas, and carry it to a discharge point or a sump basin where a pump can move it away from the house.
The right layout depends on how your crawl space is shaped, where the water comes in and where it can be discharged. That's why we look before we quote.
- Inspect where water enters and pools
- Place drain lines in the problem areas
- Connect to a discharge point or sump basin when needed
- Cover with a barrier or encapsulation if it makes sense for your home
No drain system fixes every water problem
Heavy runoff, plumbing leaks or grading outside the house may need attention too. We'll explain what a drain system can and can't do for your situation.

Questions
Crawl space drainage questions
What causes water in a crawl space?
Common causes include rain and groundwater moving through the soil, runoff from gutters or grading, and plumbing leaks. It's often a combination. Finding the source is the first part of every drainage job we do.
Do I need a drain system or a sump pump?
Many systems use both. Drain lines collect the water, and a sump pump moves it out when it can't drain away on its own. Some homes only need one piece. We'll explain what yours needs after the inspection.
Will a drain system keep all water out?
A drain system is designed to manage water that gets into the crawl space, not to stop every drop from entering. Results depend on the home and conditions, and we'll be upfront about what to expect.
Should drainage be fixed before encapsulation?
Yes. If water collects in your crawl space, it should be managed before the space is sealed with a liner. We can plan both together if you need them.
