Around 91% 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.

Check your drains and the slope around the house ahead of December. It takes an afternoon, and it can save a lot of drying later.

Before anyone arrives
The first hour after a leak in Castro Valley
Go through these in order and skip anything that doesn't feel safe. None of it is worth getting hurt over.
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.

The clock on mold is roughly 24 to 48 hours, which is why we'd rather hear from you early.
Typical build year
What to check in a typical Castro 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.

Water damage services in Castro 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.

Water Damage Repair and Restoration
Once the structure is dry, the drywall, flooring, trim and paint go back. You'll have photos and notes for your claim along the way.

Why water behaves differently in Castro Valley
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
What's under your house depends on where you are. Clay shifts with the seasons and stresses pipes, sandy ground near the coast can have water close to the surface, and hillsides hold water until they suddenly don't. Good drainage away from the house helps in all three.
Drying
Conditions change so much from place to place that the job is run on numbers. Grains per pound of moisture in the air get checked every day, and the psychrometric readings show if the dehumidifiers and air movers need to be moved or changed.
When you call
What happens after you call us from Castro 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 Alameda County. Your own home, a rental or a business, you'll know what's next before the call ends.
When the specialist arrives, the first job is finding where the water went, because that's rarely where it's pooled. Thermal cameras and moisture meters show how far it has traveled behind walls. They'll also work out what kind of water it is. Category 1 is clean water from a supply line, Category 2 is dirty, like a washer overflow, and Category 3 is sewage or floodwater. Category 3 means sealing the area with plastic, called containment, and running negative air machines with HEPA filters to keep the dirty air away from the rest of your home.
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.
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 can usually be saved in a Castro Valley 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.
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.

Questions we hear from Castro Valley
How fast can someone get to me in Castro Valley?
It depends on the time and the weather, but same-day help is what we aim for, and it's often a matter of hours. The local specialist will give you a time on the phone, so you're not left guessing.
Can I clean up water damage myself?
If it's small, clean and caught quickly, go ahead. If it has been sitting, has gone under the floor or smells bad, that's the time to call. The trouble with doing it yourself is that everything can look dry on top and still be wet underneath.
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?
Often, yes, if drying starts quickly. Hardwood can come back with floor drying mats and slow, controlled drying, though it may cup for a while and need refinishing. Carpet soaked by clean water can usually be saved with a new pad. Carpet that sewage or floodwater touched has to go.
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.
