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

Before anyone arrives
First steps for a Sunnyvale 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.

You've got about 24 to 48 hours to start drying before rot and mold become the bigger problem.
Typical build year
The usual weak spots in Sunnyvale homes
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.

Water damage services in Sunnyvale
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.
Call Now: (888) 596-0163
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.

What's different about water damage in Sunnyvale
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
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
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
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
How a water damage job works in Sunnyvale
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 Santa Clara County, and you can ask them when they can be there before you hang up. Homes and commercial buildings are both fine.
The first hour is mostly detective work. Using thermal imaging and moisture meters, the specialist traces the water through walls and floors. Then they'll sort it into Category 1, 2 or 3, from clean supply line water to sewage or floodwater. If it's Category 3, they'll seal the area with plastic sheeting and set up negative air with HEPA filtration, so the contaminated air stays put.
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.
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 comes out and what stays in a Sunnyvale 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.
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.

What people in Sunnyvale ask us
How fast can someone get to me in Sunnyvale?
We aim to have a specialist on the way the same day, often within hours. When a big storm hits all of Santa Clara 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?
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?
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?
Often, but not always. Insurers tend to pay for sudden leaks and not for long-term seepage. Flooding from outside needs its own policy. Call your insurance company early, and keep the moisture logs and photos, since they make the claim much easier.
