Housing here is older than in 56% of the 28,807 places on our list. Age alone won't cause a leak, but it does mean more pipe that's been in the wall a long time.

Before anyone arrives
First steps for a Portola Valley water emergency
You don't have to do all of this. Do what's safe, in this order, and leave the rest.
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.
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.
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.
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.
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
What to check in a typical Portola Valley home
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 Portola Valley
Water Damage Cleanup & Extraction
The more water that comes out at this stage, the less has to be dried later. Pumps and extraction units clear carpet, pad, hardwood and tile, then everything the water touched gets cleaned.
Call Now: (888) 596-0163
Flood Damage Restoration
Floodwater is never clean. It carries soil and sewage, so mud and silt get cleared, soaked drywall and insulation get cut out, and what stays gets disinfected.
Call Now: (888) 596-0163
Basement Water Damage Restoration
If your home has a basement, a failed sump pump or a backed-up drain can fill it fast. It gets pumped out, the concrete and block get dried, and someone finds out how the water got in.
Call Now: (888) 596-0163
Structural Drying and Dehumidification
Air movers and dehumidifiers run until the meters say your walls, subfloor and framing are back to normal. Not until they look dry. Until the readings prove it.

How California's climate shapes water damage in Portola Valley
Weather
Long dry months let you forget about the roof, and then a big winter storm reminds you. An atmospheric river can sit over one area for days, and hills that have burned can't hold the water back. If your gutters are still full of last year's leaves, that's what will overflow first.
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
After a dry summer, the ground can't take much water at first, so the early storms run off fast. Later in the season, saturated hills may start to move. In the valleys, clay swelling can open small cracks that let water in around the foundation.
Drying
There's no single setup that works for all of California. On each job, psychrometric readings show how much water the air is holding, measured in grains per pound, and that decides how the equipment gets set up that day.
When you call
From phone call to dry house in Portola Valley
It starts with a few quick questions: your address, what happened and how long it's been wet. Then we'll connect you with someone from our network who works in San Mateo County. Your own home, a rental or a business, you'll know what's next before the call ends.
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.
Getting the water out is the quick part. A truck-mounted or portable extractor handles that. After that, air movers sweep across wet surfaces, and low grain refrigerant (LGR) dehumidifiers take that moisture out of the room. In cold or dense spaces, desiccant dehumidifiers work better. You'll hear the machines day and night for a while, and daily psychrometric readings of the air show that they're working.
Nobody should take the machines away just because a wall feels dry. The target is the dry standard, measured from sound materials in your own home, and the job follows the IICRC S500 standard until the readings match. Ask for a copy of the daily log. Your insurer will want it.
What can be saved in a Portola Valley home
Don't write everything off just because it's wet. Clean-water carpet can usually be dried where it sits, with new pad underneath. Hardwood floors respond well to floor drying mats if you get to them early, though you may see some cupping for a while. And drywall usually needs a flood cut near the floor, not a whole new wall.
Things change when the water's dirty. Anything soft that sewage or floodwater reached, such as carpet, pad and insulation, gets thrown out. Hard surfaces get cleaned and treated. Have a professional look at any gas appliance that got wet before you turn it back on, and don't walk on a floor that's gone spongy.

Portola Valley water damage questions
How fast can someone get to me in Portola Valley?
We aim to have a specialist on the way the same day, often within hours. When a big storm hits all of San Mateo County at once, it can take longer, so it pays to call early. The steps above will help while you wait.
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?
It depends on how much got wet and for how long. A fresh leak in one room could be dry in a couple of days, while a soaked floor and walls may need a week. You'll see daily readings, so you'll know how it's going.
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?
That's between you and your insurance company, but most policies cover sudden water damage from inside the home. Flood is separate, and sewer backup is often an add-on. Your best help is good records: photos from the start, plus the daily drying readings.
