Where the water comes from

Plumbing leaks dripping through the floor, groundwater seeping through the foundation, downspouts dumping water next to the wall and condensation on cold pipes all end up in the crawl space.

Signs from above

A musty smell in the house, cupping hardwood, soft spots in the floor, higher humidity indoors and more spiders and insects can all point to a wet crawl space.

Looking underneath

With a flashlight from the access hatch, look for standing water, wet soil, a torn or missing vapor barrier, dripping pipes and white or dark growth on joists.

How it is dried

Water is pumped out, wet insulation pulled from between joists and drying done with dehumidifiers and ducted air. Readings on joists and subfloor show when it is dry.

  • Look with a flashlight
  • Check the vapor barrier
  • Check pipes
  • Smell for must

Keeping it dry

A sealed vapor barrier over the soil, working downspouts and drains, insulated pipes and in some cases a sump pump keep crawl spaces dry.

Mold

Long-term moisture grows mold on joists. See mold remediation.

Water already inside?

This article is about crawl space water in west seattle homes. If water is already on the floor, the order is the same in every West Seattle home: stop it at the valve or stop using drains if a floor drain is backing up, keep away from wet outlets and the furnace, photograph the water and the source, and call for help. Every hour water sits in a finished basement adds to what has to be cut out later.

What it tends to cost

The bill after crawl space water in west seattle homes goes up with time, dirt and finished space. A puddle caught early on bare concrete is a short visit. The same water found days later under carpet in a finished family room can mean new pad, new drywall and most of a week of equipment. Ask how the price is set before work starts and whether the company bills insurers.

West Seattle homes and crawl space water in west seattle homes

A few things about West Seattle shape crawl space water in west seattle homes: many homes have basements or crawl spaces, much of the peninsula sits on slopes that send groundwater toward foundations, the rainy season runs from October to April, and older houses still have galvanized pipe and clay side sewers. Knowing where your main valve and floor drain are, keeping gutters clear and checking the basement after every long rain covers most of the risk.

What to ask a provider

When you call about crawl space water in west seattle homes, ask how quickly they can arrive, what they will measure, whether they check behind finished walls and under pad, how long drying should take and how they price it. Ask for a Washington L&I registration number and proof of insurance, and whether they handle the rebuild. Clear answers on the phone are a good sign.

Common mistakes with crawl space water in west seattle homes

People dealing with crawl space water in west seattle homes most often wait to see if it dries, rely on a household fan, put carpet back on wet pad or throw out damaged things before photographing them. Each one adds drying days, invites mold or weakens an insurance claim. Moisture readings settle whether something is truly dry.

Vapor barriers

A heavy plastic sheet over the soil, overlapped and taped at seams and run up the walls, keeps ground moisture out of the crawl space air.

Vents

Older crawl spaces have vents in the foundation. Keep them clear of soil and plants so air can move.

A West Seattle homeowner's calendar for crawl space water in west seattle homes

Most problems related to crawl space water in west seattle homes show up at predictable times: the first big fall storms when gutters are full, the long wet stretch from November to March, the occasional winter cold snap and atmospheric river storms. A few reminders on the calendar, such as cleaning gutters in November, checking the basement after big storms and looking in the crawl space twice a year, prevent most emergencies.
