Before anyone arrives

What to do first if you're in Hillsborough

Go through these in order and skip anything that doesn't feel safe. None of it is worth getting hurt over.

  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.

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 Hillsborough homes

A lot of plumbing from these years has reached the end of its life. Galvanized steel narrows from the inside as it rusts, so weak water pressure can be a warning, not just an annoyance. Cast iron drains can crack, and fittings where old meets new are often the first thing to go.

Have a look under the kitchen and bathroom sinks and around the water heater. Any rust, drips or green staining is worth having a plumber check before it turns into a call to us.

California

How California's climate shapes water damage in Hillsborough

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

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

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

How a water damage job works in Hillsborough

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.

Before any equipment goes in, the specialist needs to know two things: how far the water got, and how dirty it is. Thermal cameras and moisture meters answer the first. For the second, there are three answers: Category 1, clean water, Category 2, dirty water, or Category 3, sewage and floodwater. With Category 3, plastic containment goes up and negative air machines with HEPA filters keep your house's air clean.

Then comes the drying, and this is the part people underestimate. Standing water comes out first, with truck-mounted or portable units. Air movers then push moist air off wet surfaces, while low grain refrigerant (LGR) dehumidifiers pull the water out of the air. If your house runs cold or the materials are dense, desiccant units can take over. Each day, readings of temperature and humidity, known as psychrometric readings, show whether the machines are keeping up.

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 you can save and what has to go in Hillsborough

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.

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.

Hillsborough water damage questions

How fast can someone get to me in Hillsborough?

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?

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?

Hardwood is more forgiving than people think. Floor drying mats pull moisture up through the boards, and refinishing can take care of what's left. Carpet can usually stay if the water was clean, as long as the pad's replaced. If the water was dirty, it can't.

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.
