Half the homes around Walnut Creek were built before this year

That's newer than 51% of the 28,807 US places we track. Newer doesn't mean leak-proof, though. It only changes what's likely to fail.

Rain and melted snow, in inches, in a typical year

Around 86% of the 30,291 places we track get more than this. Low totals can fool you. Roofs and drains get little practice here, so problems tend to show up all at once in the one big storm.

Before anyone arrives

The first hour after a leak in Walnut Creek

A few minutes now can save days of drying later. If something doesn't feel safe, skip it and tell us when you call.

  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.

Mold can get started within 24 to 48 hours, so it's worth calling even if the worst seems over.

Typical build year

The usual weak spots in Walnut Creek homes

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.

What our network handles around Walnut Creek

California

Why water behaves differently in Walnut Creek

Weather

Rain here tends to come all at once. Atmospheric rivers can drop weeks of normal rain in a few days, overwhelming storm drains after a long dry season. Above hillside neighborhoods, burn scars can turn that rain into mud and debris flows. And it's a very different story from the foggy coast to the hot inland valleys.

Buildings

A pinhole leak in an old copper line is one of the classic problems here, and it can run for months inside a wall. If your home's on a slab, a slab leak may only show as a warm spot. If it's on a raised floor, the crawlspace is where to look.

Ground

Soil varies a lot across the state. Expansive clay in many valleys and hills moves enough to crack slabs and plumbing. Sandy coastal ground drains quickly but can sit over shallow water, and steep slopes can slide once they're saturated.

Drying

What dries a house near the ocean won't be what dries one in the Central Valley, so there's no standard setup. Specialists take psychrometric readings of the air in your home, check its grains per pound each day, and change the equipment to suit.

When you call

What happens after you call us from Walnut Creek

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 Contra Costa County, and you can ask them when they can be there before you hang up. Homes and commercial buildings are both fine.

Expect a walk through the house with a thermal camera and a moisture meter, because what you can see is usually only part of it. The specialist will also tell you which of the three categories you've got. Category 1 water is clean, Category 2 is dirty, and Category 3 is sewage or floodwater. That last one changes the job, with plastic containment around the work area and negative air machines pushing air through HEPA filters.

Expect the drying to take longer than the cleanup. After a truck-mounted or portable unit has pulled out the standing water, air movers and LGR (low grain refrigerant) dehumidifiers run around the clock. Desiccant units get swapped in for cold rooms and dense materials. The specialist takes psychrometric readings each day, tracking temperature and humidity to see how fast the air is taking up water.

Looking dry and being dry are two different things. The specialist takes moisture readings from unaffected parts of your home to set a dry standard, and the machines keep going until everything wet matches it. That's how the IICRC S500 guidance says to do it, and the daily log gives your insurer the proof it asks for.

What can be saved in a Walnut Creek home

More than you'd think, if it's caught early. Carpet soaked with clean water can often be dried in place once the pad's been pulled. Hardwood is worth trying to save too, with floor drying mats and slow drying, though it may need refinishing. Drywall that's wet only at the base can be cut a little above the waterline instead of being replaced to the ceiling, which is what a flood cut is.

The exception is dirty water. Whatever soft material sewage or floodwater touched has to be removed, and the rest gets an antimicrobial cleaning. Don't relight a gas heater or water heater that sat in water, and if a floor feels soft, stay off it and mention it on the call.

Common water damage questions in Walnut Creek

How fast can someone get to me in Walnut Creek?

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 Walnut Creek needs help at once.

Can I clean up water damage myself?

Some of it, yes. A bit of clean water on tile is a job for a mop and a fan. It's different when water has got under the flooring or into a wall, or when it's dirty. Household fans can't dry a wall cavity, and sewage isn't safe to handle.

How long does it take to dry out a house?

A small leak that's caught early may dry in two or three days. A flooded room with wet subfloor and insulation can take a week or more, and repairs start after that.

Can wet hardwood floors and carpet be saved?

Quite often. Floor mats and steady air can save hardwood that would otherwise be torn out, so tell the specialist about it first thing. With carpet, it all depends on the water: clean means dry it and replace the pad, sewage or floodwater means it comes out.

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.
