Before anyone arrives

The first hour after a leak in San Geronimo

You don't have to do all of this. Do what's safe, in this order, and leave the rest.

  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.

The clock on mold is roughly 24 to 48 hours, which is why we'd rather hear from you early.

Typical build year

What tends to fail in San Geronimo houses like yours

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.

How California's climate shapes water damage in San Geronimo

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

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 Geronimo

Don't worry about having the right words. Just tell us what you're seeing. We'll get your address and a rough idea of the damage, then put you through to a specialist in our network who works around San Geronimo. They handle homes and commercial property, and they'll give you a time.

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.

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 San Geronimo 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.

Contaminated water is where the rules get strict. Sewage or floodwater means the carpet and pad come out, along with wet insulation, and what's left gets an antimicrobial treatment. It's also not safe to relight a gas appliance that's been underwater until someone's checked it, and a soft floor needs a look before anyone stands on it.

San Geronimo water damage questions

How fast can someone get to me in San Geronimo?

We aim to have a specialist on the way the same day, often within hours. When a big storm hits all of Marin 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?

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?

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.
