Before anyone arrives

What to do first if you're in Mercer Island

You don't have to do all of this. Do what's safe, in this order, and leave the rest.

  1. Shut off the water

    Look for the main valve near the meter or where the line comes into the house, and turn it slowly, since older valves can stick. If it's one fixture, its own shutoff valve will do.

  2. Stay clear of the power

    If you can reach the breaker panel without stepping in water, switch off the wet rooms. If you can't, leave it alone, stay out of the water and tell us when you call.

  3. Take pictures first

    Before you clean up, photograph the water, where it came from and whatever it damaged. Your insurance company will ask, and you only get one chance at those shots.

  4. Rescue what you can

    Move rugs, papers, photos and electronics to a dry room, and prop furniture up off the wet floor. Everything else can wait.

  5. Let the air move

    If the water is clean and the power's safe, open interior doors and run the fans you have. Stay out if it's sewage or floodwater, and keep that air away from the rest of the house.

Typical build year

What to check around Mercer Island before it leaks

Homes from these decades often still have their first galvanized pipes, or a mix of galvanized and newer copper. Where those two metals meet is a common place for a leak to start. Some homes from the middle of this period also have sewer lines made of a tar-paper pipe called Orangeburg, which sags and collapses with age.

Look where pipes join around the water heater and under sinks, and check for rust or green crust. Slow drains in several rooms are worth a sewer camera, and that's a lot cheaper than a backup.

How long wet seasons shape water damage in Mercer Island

Weather

The rain here wears things down slowly. A small gap in the siding or a tired roof can let in a little water all winter long, and you may not notice until spring. To the east, the risk looks different, with hard freezes and ice taking most of the blame.

Buildings

Have a look in your crawlspace at the end of the wet season. That's where a slow leak or poor drainage shows up, and damp air there can reach the floor above. Wood siding and cedar roofs look great, but they do need upkeep to keep the water out.

Ground

Wet ground is the normal condition here for months at a time. Heavy clay doesn't let it through, so groundwater can stand under a house long after a storm. On a hillside, all that water is also working its way downhill toward your foundation.

Drying

Outside air won't help when it's this wet. Specialists seal off the area and run desiccant dehumidifiers, which keep working in cool, damp conditions where other machines slow down. It's especially useful in crawlspaces.

When you call

From phone call to dry house in Mercer Island

We'll ask where you are, what happened and whether the water's still running. That takes a couple of minutes. Then we'll connect you with a specialist from our network who works in King County, and you can ask them when they can be there before you hang up. Homes and commercial buildings are both fine.

Before any equipment goes in, the specialist needs to know two things: how far the water got, and how dirty it is. Thermal cameras and moisture meters answer the first. For the second, there are three answers: Category 1, clean water, Category 2, dirty water, or Category 3, sewage and floodwater. With Category 3, plastic containment goes up and negative air machines with HEPA filters keep your house's air clean.

Then comes the drying, and this is the part people underestimate. Standing water comes out first, with truck-mounted or portable units. Air movers then push moist air off wet surfaces, while low grain refrigerant (LGR) dehumidifiers pull the water out of the air. If your house runs cold or the materials are dense, desiccant units can take over. Each day, readings of temperature and humidity, known as psychrometric readings, show whether the machines are keeping up.

So how do you know it's done? It's done when the numbers say so. A dry baseline from untouched materials in your house is the target, and each wet area has to reach it before the equipment leaves. It follows the IICRC S500 standard, and you get a record of the readings for your insurance claim.

What can be saved in a Mercer Island home

Most people expect to lose more than they do. Carpet that's only had clean water on it can usually be dried, though the pad underneath gets replaced. Drying mats can bring cupped hardwood back, given time. Walls often need only a flood cut, where the bottom of the drywall comes off and new board goes in.

Sewage and floodwater are a different story. Carpet they've touched has to go, and what stays gets cleaned and treated with an antimicrobial. Two more things to check before you use the room again: a gas appliance that sat in water, and any floor that feels soft underfoot.

Mercer Island water damage questions

How fast can someone get to me in Mercer Island?

In most cases you'll have someone on the way that day. You can ask for a time when you're connected with the specialist. It may take longer after a storm, when much of Mercer Island needs help at once.

Can I clean up water damage myself?

You can handle a minor spill if it's clean water and it hasn't gone anywhere. For anything that's reached the carpet pad, the walls or the floor below, professional drying really does make a difference, and floodwater or sewage should be left to people with the right protective gear.

How long does it take to dry out a house?

Usually three to five days for the drying alone. The specialist can tell you more after the first readings. Materials such as hardwood, plaster and concrete hold on to water longer, and repairs can only begin when they're dry.

Can wet hardwood floors and carpet be saved?

Usually, with clean water and a fast start. Drying mats sit on hardwood and draw the moisture out slowly so the boards don't split. Sanding and refinishing can fix any cupping that's left. Carpet needs a new pad, and it can't be saved at all after sewage or floodwater.

Will my insurance pay for water damage?

It usually depends on where the water came from. A homeowners policy usually covers a burst pipe. Outside flooding needs separate flood insurance, and sewer backup often needs an add-on. It's worth reading your policy, and it's worth having those photos.
