Expert Plumbing in San Jose, CA Area, for Your Home and Business

When you need plumbing in the San Jose, CA area, you can’t wait all day. Whether it’s a leaky faucet, a rocking toilet, or a busted line behind your washing machine, ask yourself how long your household could survive without moving? We always roll out in minutes to address the cause and leave the site clean when we’re done; no talk of “maybe next week,” and no surprise pricing; just excellent work done the best way we can do it.

Why Residents Continue to Choose Dyer Demand Plumbing

Friends talk. Coffee at Chromatic, when parents chat at a Willow Glen Little League game about contractors. We continue to hear that neighbors have chosen us and stack the reasons in a few areas:

  • Reliability. We show up at the time we said we would; if we run late – which rarely happens, but traffic happens – we text you that we are delayed.
  • Real talk. We call a “dielectric union” “that metal piece that stops two different pipes from eating each other.” The kids understood, so we’re assuming you understood too!
  • Grounded pricing. We give you a written estimate for every job. If another licensed crew writes you a less expensive estimate, we will trim five percent off our estimate.

Those practices have brought us over 1,000 successful calls in six short years. Homeowners don’t think twice about handing us their front-door key while they run errands because we have a California Contractors State License Board C-36 license and a clean slate with the Better Business Bureau plumbing standards.

Common Plumbing Challenges in San Jose

The valley’s topography creates its unique plumbing problems. Hard water can scale up storage water heaters so quickly you can hardly say “morning shower.” Small but often occurring earthquakes loosen copper joints. Well-meaning tree roots from generous shade oaks chase moisture along aging sewer laterals. And, high-tech schedules don’t help either: remote workers jump from one back-to-back video call to another, keeping bathrooms active all day long.

Here are the breakdowns we fix most often:

  • Water heaters, repair and prevent unnecessary replacement; also tankless upgrades.
  • Leak detection in walls, slabs, and crawl spaces.
  • Drain cleaning with cable machines, and with hydro-jetting.
  • Sewer-line repair with pipe bursting, for deep roots.
  • Fixture installs: low-flow toilets, WaterSense faucets, and garbage disposals that can chew through corn husks.
  • Copper repiping for older galvanized lines in Naglee Park and the Rose Garden.

Every faucet, shower head, and toilet that we bring into your home meets the efficiency guidelines of EPA WaterSense. Smaller water bills, and less strain on reservoirs that are drought-prone.

24/7 Emergency Plumbing Response

Flooded hallway at 2 a.m.? Just call 408-826-7257. A real person answers. Based on our shop’s location at the junction of I-880 and US-101, you can bet your address is 30–60 minutes away. Our first order of business is to stop the flow. We keep mainline keys, quarter-turn valves, and heavy-duty repair clamps right on the truck.

While you wait, follow the steps to water shut-off by American Red Cross. Turn the house valve clockwise, open the lowest faucet to relieve the pressure, and set the water heater to “pilot.” If you need help with anything, the Department of Energy water-heater guide has tips on safely shutting down.

Pro tip: Snap a phone photo of your main valve now, before the trouble! If a client takes our advice, they save us about ten minutes of repair time, because we don’t have to figure out which fixture we are going to.

Transparent Pricing & Special Partnerships

San Jose rents and mortgages are some of the highest in the nation. We won’t add to the stress. Instead, if you happen to call us for ten or so common jobs, like swapping a garbage disposal, or installing a new pressure-regulating valve, we provide base rates just over the phone! Combinations of plumbing jobs get a line-by-line proposal and are valid for 14 days.

Landlords and apartment managers love our special pricing for higher volume clients. If you sign a service agreement with us, we can offer the best priority scheduling and hourly rates. If you provide us with a written estimate from a similar licensed, bonded, and insured company, we beat it by five percent, EVERY TIME.

All work comes with at least a two-year parts and labor warranty. Major jobs like whole-home repipes or mainline replacements come with extended warranties, and these will be outlined in writing before the first hammer swings.

What To Do Before Your Plumber Arrives

Act quickly to avoid ceiling stains and warped floors. If you have a broken pipe, or a toilet that is overflowing, do these three things:

  • Shut Off Water. You can close the valve at the fixture (if there is one) or the house main.
  • Kill Power. If water has reached outlets or appliances, switch it off in the breaker.
  • Move Valuables. Electronics and heirlooms don’t want moisture.
  • Ventilate. Open the windows and run the fans to slow down mold.
  • Document. Take pictures for insurance before cleaning up.

Still not sure if you should call? The San Jose Water outage map will help. If the utility is saying they are turning your block off, you might be in luck. If in doubt, call us. It’s always free to ask for advice.

DIY Is Okay – But to a Point

We love homeowners who know how to use tools. A plunger, a five-dollar washer, or a little PTFE tape can solve lots of problems. But remember – YouTube can’t feel the corroded fitting. And when the simple fix gets complicated, the value of a professional offering plumbing in the San Jose, CA area can save you hundreds of dollars by catching hidden damage before it is too late.

Seasonal Tips for Plumbing in San Jose, CA Area

While winter is mild here, the South Bay will still dip below freezing overnight a few times a year! So, before Thanksgiving be sure to wrap the exposed hose bibs. There should be little need to remember to drain your irrigation lines if you are heading out of town for a ski trip. With spring comes pollen, as well as soft ground; so now is a good time to check all the clean-outs for any root intrusions. And during those hot August afternoons when the temperature is pushing 90 degrees, be sure to relieve pressure on your water heater, and set the water temperature down to 120 °F. Simple things like these extend the life of your entire plumbing system while reducing energy usage. These are just some aspects of effective plumbing in San Jose, CA area that we consider.

Sustainable Upgrades That Are Worth the Cost

Homeowners who are eco-conscious love to consider options that will help them reduce both their bills and their carbon footprint. Here are three upgrades we find ourselves installing every week:

  • High-efficiency toilets. New dual-flush toilets cut the usage of water by about 20,000 gallons a year. Dual-flush toilets often qualify for local rebates. See the city’s water-saving tips page for more information.
  • Recirculating pumps. If you’re sick of waiting up to two minutes for hot water, recirculating pumps help eliminate waiting by moving the lukewarm water back to your heated tank (through piping) until the tap calls for hot water. Quickly this daily waiting will add up to thousands of gallons saved every year.
  • Smart leak sensors. Connected Wi-Fi leak sensors will text your phone as fast as they sense moisture. Sometimes all it takes is a quick text notification to save you from flooding your entire kitchen. These are all part of smart home plumbing in San Jose, CA area solutions.

Serving Every Neighborhood in San Jose

Our vans traverse all parts of the 408 every day, from Almaden Valley to Alviso. We fix slab leaks in Blossom Valley ranchers, tune pressure regulators in penthouses on high rises right near Adobe, or install smart shower systems in newly built townhomes in Berryessa.

We serve neighboring cities too—Sunnyvale, Mountain View, Santa Clara—but we truly love to work in the neighborhoods Jeremy rode through as a kid. Wherever you live in Santa Clara County, it would be our privilege to make your next call your easiest service call yet.

Have Your Plumbing Issues Been Seen Early?

If you are spending time doing Google searches for plumbing in San Jose, CA area, the chances are that whatever your plumbing problem is, it has already become an urgent issue. Instead of that frantic tap-tap-tap whenever you have time on your phone, invest the time to do these simple checks. You could uncover a potential headache days or even weeks before your plumbing problem urges you to do that last-minute Google search for plumbing in San Jose, CA area at midnight.

  • Listen for hissing behind your walls, and hopefully it will remain in that stage. All early leaks are whispering somewhere early before they begin to roar. When you hear that hissing, don’t hesitate to call us. Expert plumbing in San Jose, CA area can work in the walls, and replace a section of pipe instead of the entire ceiling.
  • Check consecutive water bills. If your bills spike 10 percent, and you haven’t bought new appliances, you probably have a leak somewhere. In most cases, an expert in plumbing in San Jose, CA area with a camera inspection will find the leak, usually in an area you cannot see.
  • Water temperature at the tap. Are you taking lukewarm showers? If so, you could have sediment building up in your water heater tank. Periodic flushing by expert plumbing in San Jose, CA area will expand the life of your heater.

Stay alert, and you can save cash and headaches down the road.

Why Is Plumbing in San Jose, CA Area Unique?

Every city has water lines, but plumbing in San Jose, CA area deals with a combination of unique challenges that are not combined like this anywhere else. Silicon Valley is boomtown territory, and the constant remodel means that the antiquated supply pipe might be two inches from the brand new smart appliance. High soft wintertime rains convert soil to mush, which diverts the foundation, and stresses sewer joints. Therefore, addressing your plumbing in San Jose, CA area needs requires a plumbing crew that can watch building trends, as well as the soil reports.

Local codes are a factor as well. The permits for plumbing in San Jose, CA area require water-efficient fixtures and backflow devices. We handle the permits, the schedules, and stay on-site for the city inspection to the moment the inspector signs.

Lastly, our Mediterranean environment assists us with drought-wise design. As good citizens committed to smart plumbing in San Jose, CA area practices, we recommend leak-detection devices and grey-water loops because responsible plumbing in San Jose, CA area helps conserve the limited resource remaining in the San Francisco peninsula and South Bay area.
