$100–$800
A simple sink clog is cheap; main sewer line hydro jetting costs more.
$800–$5,500
Tank replacements start around $800; tankless installs with gas line upsizing reach the top end.
$150–$1,200
A faucet swap is straightforward; shower valve replacements with tile work cost more.
$2,000–$15,000
Trenchless methods save on restoration costs; full excavation adds labor and permits.
$4,000–$15,000
Price scales with home size, number of fixtures, and whether PEX or copper is used.

A basic carbon filter is affordable; whole-house softener + RO combo is the premium option.

$3,000–$20,000
A single bathroom remodel is on the low end; full ADU plumbing from slab to finish is on the high end.

Repiping is a significant investment ($4,000–$15,000), but catching the warning signs early can save you from emergency failures and water damage.
Homes built before 1960 in San Diego often have galvanized pipes that corrode from the inside out. If you can see silver-gray pipes with threaded fittings at your water heater or under sinks, they are likely galvanized. These pipes narrow over time, restricting flow and leaching rust into your water.
If multiple fixtures in the house have weak flow — not just one faucet — the problem is usually mineral buildup inside aging pipes, not the city supply. A pressure test at the meter vs. at your fixtures will confirm whether internal corrosion is the cause.
Brown or orange-tinted water, especially when you first turn on a tap in the morning, indicates corrosion inside the pipes. Running the water for a minute may clear it temporarily, but the pipes are actively deteriorating and the problem will get worse.
A single pinhole leak is a repair. Two or three leaks in different locations within a year is a pattern — the entire pipe system is failing at the same rate, and patching individual spots is not cost-effective compared to a full repipe.
Copper pipes typically last 50-70 years, but galvanized pipes last only 20-40 years in San Diego's hard water. If your home was built before the mid-1980s and still has original plumbing, a proactive repipe prevents emergency failures and potential water damage.
Not sure if you need a repipe? Our team can run a pressure test and camera inspection to assess your pipes without any obligation. Most inspections take under an hour.
Hiring the wrong plumber is expensive. These eight questions help you separate professionals from handymen before any money changes hands.
Why it matters: California requires a C-36 plumbing license for any plumbing work over $500. Ask for the license number and verify it on the CSLB website (cslb.ca.gov). An unlicensed plumber cannot pull permits, and any work they do may not pass inspection.
Why it matters: If an uninsured plumber damages your property or gets injured on the job, you could be financially responsible. Ask to see a certificate of insurance — a legitimate plumber will have one ready.
Why it matters: Verbal quotes can change once the work begins. A written estimate locks in the scope and price. Be cautious of any plumber who refuses to put numbers on paper before starting.
Why it matters: Water heater replacements, repiping, sewer line work, and gas lines all require permits in San Diego. Unpermitted work can create problems when you sell your home and may void your homeowner's insurance.
Why it matters: A confident plumber stands behind their work. Ask specifically about the labor warranty period, whether parts have a manufacturer warranty, and what is covered if something fails within the first year.
Why it matters: Plumbing projects sometimes reveal hidden problems — corroded valves, code violations from previous work, or damaged subfloor. A trustworthy plumber will stop, explain the issue, provide a revised estimate, and get your approval before proceeding.
Why it matters: Check Google reviews, Yelp, or ask for phone numbers of recent customers in your area. A plumber with a track record of satisfied customers in San Diego is more reliable than one who just offers the lowest bid.
Why it matters: Know when the plumber will arrive, how long the job should take, and whether they clean up after themselves. Professional plumbers protect your floors, remove debris, and leave the work area as clean as they found it.
Some plumbing tasks are genuinely simple. Others can cause thousands of dollars in damage if done wrong. Here is a quick reference.
Unscrew, apply thread tape, screw on the new one. No tools beyond pliers.
A cup plunger on a sink or a flange plunger on a toilet handles most simple clogs.
Turn off water, flush, swap the flapper. A $5 fix that stops a running toilet.
Know where your main shut-off valve is. Turn it clockwise, then call a plumber.
Requires opening the wall, soldering or crimping, and pressure testing. Risk of water damage if done incorrectly.
Gas and electrical connections, T&P valve routing, seismic strapping, expansion tanks, and a city permit are all required.
Requires commercial-grade equipment. A rented drain snake can damage pipes or get stuck if used incorrectly.
Gas leaks are dangerous. California law requires a licensed contractor for all gas line installation and repair.
General rule: If the task involves cutting into walls, working with gas, connecting to the sewer system, or requires a permit, call a licensed plumber. The cost of professional work is almost always less than the cost of repairing DIY water damage.
