Common signs

Signs your crawl space may need a sump pump

  • Standing water that stays

    Water that sits under the house for days after rain.

  • Water every rainy season

    The same problem returns each fall and winter.

  • A low spot that floods

    One area of the crawl space where water always ends up.

  • Drainage with nowhere to go

    Drain pipes that need a collection point to empty into.

  • An old pump that can't keep up

    An existing pump that runs constantly, fails or no longer clears the water.

What a crawl space sump pump does

A sump pump sits in a basin at a low point in the crawl space. Water collects in the basin, and when it rises, the pump sends it out through a discharge line away from the house.

A sump pump works best as part of a complete water plan. Drain pipes often feed the sump, and a barrier over the ground keeps the space cleaner once the water is under control.

  • We locate the exact spot where water naturally pools under your home
  • Install a sump basin and submersible pump sized for your crawl space
  • Route discharge lines out and away from your home's foundation
  • Keeping the water out and your peace of mind in

We'll explain exactly what you're getting

We'll cover what we're installing, where it discharges, and how to keep it running year after year.

Questions

Sump Pump Installation questions

Do I need a sump pump in my crawl space?

If water collects under your home and can't drain away on its own, a sump pump is the solution. We'll inspect your crawl space and recommend the right setup.

Where does the water go?

Through a discharge line we route out of the crawl space and away from your home's foundation. We'll plan the discharge point with you so it fits your property.

Will a sump pump fix my water problem?

A sump pump removes the water that collects under your home and sends it away from your foundation. Paired with drainage and a vapor barrier where your crawl space needs them, it keeps the space dry and protected.

Do sump pumps need maintenance?

Every pump should be checked periodically to make sure it runs and the discharge line stays clear. We'll walk you through it.

How do I get an estimate?

Getting started is easy. Call or text (360) 470-4956, or fill out the form on this page. We'll learn what's going on beneath your home, schedule a time to take a look, and give you a straightforward sump pump estimate.

I feel very happy and pleased with the work Jon did under my house. He cleaned up the entire crawl space!! Jon is hard working and I would recommend him highly.

Henry RettingerGoogle review

I've been working w/ Jon and CrawlspacePros on some structural issues in my old home, and they've been kind, quality, honest, and they care that I'm happy with the outcome. That means a lot to me. Thank you gentlemen.
