Seasonal timing

Hot, dry stretches like this one are when expansive clay pulls away from a slab hardest, and that's usually the point a hairline crack under the floor turns into standing water.

Common questions

How much does a plumber cost?

It depends on the job and how bad the problem is. That is why the first step is a phone call. Describe the problem and get your free estimate on the phone, with upfront pricing.

Will I talk to a real person?

Yes, you will.

Do I need to fill out a form?

No forms and no waiting on emailed quotes. One phone call is all it takes.

Can I get help at night or on a weekend?

We have plumbers ready to help families in the community 24/7, but moment-to-moment availability depends on demand. Call to find out how soon we can service your home.

Why would summer be a bad season for a water heater to fail in Sunnyvale?

Water heaters already run harder through the hottest months, between higher usage and heat load on units installed outside conditioned space, so failures cluster in summer for a Sunnyvale household more than people expect from an appliance most think of as a winter concern.

When should an irrigation system get shut down for the winter in Sunnyvale?

Before the first hard freeze settles in for good. A backflow preventer left charged with water past that point is a common freeze failure on a Sunnyvale property, especially in newer subdivisions where in-ground irrigation is standard.

Is freezing weather a real concern in Sunnyvale or mostly a non-issue?

It's a real concern, just a limited one. Roughly 24 nights a year get cold enough to freeze, which is enough to catch an unwrapped pipe but not enough to justify the kind of winterizing a colder climate would need.

Why would the water bill jump with no obvious leak in the house?

A running toilet or a slow outdoor faucet leak is the usual explanation, and both are common enough that checking the meter with every fixture off is worth doing before a Sunnyvale homeowner assumes something more serious is going on.

Should I wait to call?

You already know that plumbing problems don't go away on their own. And waiting just increases the risks to your house. Plumbers see this hesitation all the time. Instead of regretting not calling earlier, just make that 2-minute call now and get your free estimate.
