What Services Do Los Altos Plumbing Companies Offer?

Leak Repair

Unaddressed plumbing leaks will raise your water bills and may damage the area around the pipes. Plumbing professionals can identify the precise source of the leak and repair it to prevent future problems.

Clog Repair

Clogged pipes and drains may lead to backflow, water damage, and flooding. Los Altos plumbers can remove blockages and advise you on how to prevent them in the future.

Pipe Replacement

Pipes can wear out or become damaged with age. If a pipe bursts, leaks, or shows signs of wear, a professional plumber can replace it.

Fixture Installation

Some fixtures wear down with age and require installing something new. Other times, you may replace them as part of a renovation. A plumber can install something as simple as a new faucet or as complex as a new shower, toilet, bathtub, or sink.

Gas Repair

In addition to typical plumbing work, some plumbers train to find and fix gas leaks from ovens, radiators, and other appliances. Should you smell the familiar scent of a gas leak, leave the house and call your utility provider.

Annual Inspections

Plumbing systems must withstand wear and tear from consistent daily use. Protect your home's pipes by arranging yearly checkups from an expert Los Altos plumber. Inspections can uncover problems while they’re still incipient, and spotting and repairing them early may lower your long-term repair bills.

Emergency Services

Overflowing toilets and burst pipes rarely happen at convenient times. That's why many plumbers provide urgent repair services to handle these unforeseen issues. Emergency fixes are usually more expensive than planned repairs, but prompt attention is crucial to avert the possibility of further property damage.

Check Licensing and Insurance

The California Contractors State License Board issues state C-36 licenses to Los Altos plumbers. Business owners must meet all experience and exam requirements. Also, make sure your plumber is properly bonded and insured in case of any accidents or damage during the job.

Check Union Status

You don't necessarily have to hire a union plumber, but choosing one means that your technicians usually have passed stronger vetting and training standards.

Assess Their Experience

Plumbers with extensive local experience will be more familiar with Los Altos' most common plumbing conundrums. By choosing a small plumbing company, you could get issues solved faster.

Read Customer Reviews

Customer feedback on Google Reviews and the Better Business Bureau (BBB) website will help you determine how companies handle complaints, as well as the quality of each team's customer service and workmanship.

Compare Multiple Quotes

To find the best value, get multiple different quotes from different plumbing companies. If a company charges significantly more or less than local market rates, it's better to go with a different team.

Ask About Warranties and Guarantees

A confident plumbing company will back up its work with guarantees. Ask each company how long its warranty lasts and what it encompasses. If you're having new fixtures or appliances installed, you should also determine what manufacturer warranties apply.

Frequently Asked Questions About Plumbing in Los Altos, CA

Plumbers can fix these common problems:

  • Clogged drains
  • Lack of hot water
  • Low water pressure
  • Leaks and water damage
  • Running toilets
  • Septic and sewer line issues

There are no expectations for you to tip your plumber. You may offer a tip for exceptional service, but first, ensure the company you've chosen doesn't block its employees from accepting them.

Some Los Altos homeowners do fix running toilets and unclog drains themselves. However, even if you choose to DIY, you should still have a professional plumber ready to call in case the issue recurs or you can't identify the cause. An improper "fix" can cause significant damage.

Many plumbers offer both web and phone scheduling. For emergency services, you'll need to call.

Yes. If a plumber's license allows them to do so, they can fix leaky, unusual-sounding, or ineffective water heaters. We also recommend getting an inspection if your water heater is more than 8–12 years old, as issues are more likely to occur with age. Water heater components can pose fire and surface temperature hazards, so we recommend leaving repairs to the pros for your safety.
