Housing here is older than in 66% 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.

Around 87% of the 30,291 places we track get more than this. Less rain doesn't mean less risk indoors. Most damage here starts with plumbing, and when a big storm does come, dry ground doesn't soak it up.

Before anyone arrives
First steps for a San Mateo water emergency
These are the steps that help most before anyone gets there. Do what you safely can.
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 around San Mateo before it leaks
By now, most homes from this era have had some plumbing replaced, and the leftover sections are usually the risk. Look for gray galvanized pipe next to newer copper or plastic, because those joints can corrode. If you've had a few sewer backups, the old line itself may be the cause.
It's also worth replacing rubber washing machine hoses with braided steel. It's a ten-minute job, and those hoses cause a surprising number of flooded laundry rooms.

From first call to final repair in San Mateo
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 San Mateo
Weather
Most of the year's rain falls in a few big winter storms. Drains and gutters full of a dry season's leaves back up quickly, and steep ground can let go after days of rain. And a short drive can take you from damp sea air to dry heat, so two houses in one county can have very different problems.
Buildings
Plenty of California homes look fine on the outside while stucco quietly holds water behind it. Water heaters strapped in a garage or closet, older pipe joints and connections that have moved in an earthquake are all common sources. So are air conditioning lines in the attic in the hotter valleys.
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
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 to expect once you've called from San Mateo
First we'll want to know three things: where you are in San Mateo, where the water came from and if it's stopped. From there, we'll connect you with a local specialist from our network, so you're speaking to someone who works in San Mateo County. That goes for homeowners, landlords and businesses alike.
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.
Drying is a process, and you'll have strange machines in the house for a few days. The bulk of the water goes first, by truck-mounted or portable extractor. Air movers then lift moisture off surfaces, and low grain refrigerant (LGR) dehumidifiers remove it from the air. A cold building or dense material may need desiccant units instead. Daily psychrometric readings show if the air is still pulling water out.
The finish line isn't when things look dry. Readings from dry wood and drywall in your own house set the target, called the dry standard, and the equipment stays until the wet areas reach it. That's the IICRC S500 standard for water damage at work, and those daily records are what your insurance company wants to see.
What you can save and what has to go in San Mateo
A lot of it can stay if you move quickly. If the water was clean, the carpet is often fine once the pad is replaced. Hardwood needs slow, careful drying with mats, and it may want refinishing at the end. Drywall is the easy one: a flood cut takes off the wet part, a little above the waterline, and the top of the wall is untouched.
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.

Questions we hear from San Mateo
How fast can someone get to me in San Mateo?
Often within hours. Our network covers San Mateo County, and we'll look for whoever can reach you soonest. Storms are the exception, because every crew in the area gets busy, so please don't wait to see if it gets worse.
Can I clean up water damage myself?
A small spill of clean water on a hard floor? Sure. Towels and a fan will do it. But if the water's in the walls, the carpet pad or the subfloor, or it came from a sewer or a flood, you'll want it extracted and properly dried. What you can't see is what keeps causing damage.
How long does it take to dry out a house?
Most homes take three to five days of drying once the water's out. Dense materials such as hardwood and plaster can take longer, and any rebuilding comes afterward.
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?
Many water losses are covered, so it's worth checking. The usual line is sudden versus gradual: a burst supply line is generally covered, and a slow drip often isn't. Flood damage needs a separate flood policy, and a sewer backup may need an extra rider.
