KCB Plumbing handles residential plumbing for homes across Orange County from our office at 3303 Harbor Blvd in Costa Mesa. That covers everyday repairs and maintenance, fixture repair and replacement, and plumbing for new construction and remodeling projects. Keevin Blue founded KCB in 1998, and the company is licensed, insured, and bonded (Lic #604044).
Most home plumbing calls start with a symptom rather than a known cause: a dripping faucet, a running toilet, low pressure, a slow drain, discolored water, or a damp spot under a sink. We work out what is actually wrong, explain the options in plain language, and give you an upfront flat-rate price before approved work begins.
How KCB Approaches A Home Plumbing Job
Start by describing the problem by phone. Many common services can be estimated over the phone at no charge. When the cause is hidden or the job is more complex, a plumber may need to see it in person first, and that visit may carry a trip charge; confirm it when booking. On site, we assess the problem, explain whether a repair or a replacement makes more sense, and quote a flat-rate price before approved work begins. After the work, we test the fixture or line we worked on.
Repairs And Maintenance: When To Call
Call when a faucet or toilet keeps leaking or running after a simple fix, when pressure drops at several fixtures, when water turns discolored, or when water stains, musty odors, or a higher water bill appear without an obvious reason. Even small leaks can point to larger issues such as pipe corrosion, high water pressure, or failing joints. If water is actively leaking, stay away from wet electrical equipment and, if it is safe, close an identified, accessible shutoff before you call.
Fixture Repair And Replacement
Faucets, sinks, toilets, showers, and tubs see daily use. A worn part can often be repaired; an older fixture that needs frequent repairs or shows visible corrosion may be worth replacing. We can install a fixture you have already purchased. Send the model number before the appointment so compatibility with your existing supply and drain connections can be checked, and tell us if the shutoff valves under the fixture are hard to turn.
Remodeling And New Construction
Moving a sink, relocating a shower drain, or adding a bathroom means rerouting supply lines, adjusting drain slopes, and coordinating with other trades. Share your plans or a sketch, the fixtures you have selected, and your contractor's schedule so the plumbing scope can be reviewed before work begins. Work that moves or adds piping generally needs a permit and inspection; we confirm what applies to your project when we define the scope.
Older Pipes And Local Water
Orange County homes span many construction eras and pipe materials. Older galvanized supply pipes can develop internal corrosion, which may contribute to discolored water, reduced pressure, or leaks. Older drain systems may include cast iron that has deteriorated over time. Water hardness also varies by local supplier; your supplier's annual water quality report lists its figures. KCB confirms what is installed and its accessible condition before recommending a targeted repair or a repipe.
What To Have Ready When You Call
Note which fixtures or rooms are affected, when the problem started, and whether it is constant or only happens with certain fixtures. Have photos, fixture model numbers, the approximate age of the home, any known pipe material, and previous repairs ready. Know where your main water shutoff is, and mention gate codes, parking limits, or HOA rules for condos and townhomes. Call (714) 894-6520 Monday–Friday, 7 AM–6 PM, and Saturday–Sunday, 8 AM–5 PM.

Frequently Asked Questions
What residential plumbing work does KCB Plumbing handle?
KCB handles residential repairs and maintenance, fixture repair and replacement, and plumbing for new construction and remodeling projects. Related home services, including drain cleaning, leak detection, repiping, water heaters, and water treatment, are covered on their own service pages.
Do you give free estimates for home plumbing work?
KCB provides free over-the-phone estimates for many common services. Complex jobs, hidden problems, and larger projects such as repipes may need a visit to the property first, and a trip charge may apply. You receive an upfront flat-rate price before approved work begins.
Can you work on older homes with original plumbing?
Yes. Older homes may have galvanized supply lines, clay sewers, cast iron drains, or other legacy materials that require careful diagnosis before work is quoted. KCB inspects the accessible piping, explains what is installed, and discusses whether a targeted repair or a repipe makes sense.
Who handles plumbing problems in a condo or townhome?
Responsibility for shared piping depends on the building and the association's rules. Shared buildings may require coordination with an HOA, landlord, or property manager, so confirm who controls the affected pipe and any shutoff before approving work.
