Plumbing Contractor Ventura County | Master Construction

Your Plumbing Contractor in Ventura County

Plumbing problems never pick a convenient time. Master Construction is a plumbing contractor serving all of Ventura County, handling leak repairs, whole home repipes, water heater replacement, and fixture installation, backed by 30 years of building and remodeling the homes those pipes run through. Family owned since 1994, our licensed team (Lic. #1027281) fixes the problem you called about and flags the one waiting to happen.

A Plumbing Contractor Who Sees the Whole House

Because we are general contractors first, our plumbers see the bigger picture behind the leak. We know what that stain on the ceiling means for the framing above it, and we can open, repair, and refinish the wall ourselves instead of leaving you with a hole and a second contractor to find. One call covers the pipe and everything around it.

A repair is only as good as its connections. Copper gets cleaned, fluxed, and sweated dry, or joined with press fittings where a torch near old framing is a bad idea. PEX runs get supported so they cannot chafe, dielectric unions separate copper from galvanized so the pipes do not eat each other, and every shutoff we touch gets exercised and replaced if it will not hold. Then everything is pressure tested before the wall closes.

Our Plumbing Process

Straightforward service without the runaround:

  • Diagnose. We find the actual source, not just the symptom, using moisture readings where needed.
  • Explain and price. Clear options and upfront pricing before any work starts.
  • Repair or replace. Brass valves and code approved fittings, not the cheapest part on the truck.
  • Restore. Drywall, tile, and paint put back like nothing happened.
  • Verify. We test everything under pressure before we call it done.

Repipes, Water Heaters and Remodel Plumbing

Older Ventura County homes with galvanized or polybutylene pipe are leaks waiting on a schedule. We repipe entire homes with copper or PEX, usually in days not weeks, and patch every opening we make. Remodeling instead? Our plumbers rough in kitchens, bathrooms, and additions as part of the same crew that builds them.

Local conditions are half the diagnosis. Ventura County water runs hard, so mineral scale shortens water heater life and clogs fixture cartridges years ahead of schedule. The postwar tracts in Oxnard and Santa Paula still carry original galvanized, and 1960s slab homes ran soft copper under the concrete, where a pinhole shows up as a warm spot on the floor. Every water heater replacement gets a permit, seismic strapping, and a proper flue check, because the inspector will look and so do we.

Questions

Plumbing - FAQ

My water bill jumped but I do not see a leak. What now?

Check the meter with every fixture off. Movement means water is going somewhere, commonly a slab leak, an irrigation line, or a running toilet flapper. We locate it before opening anything, because guessing where a slab leak is means opening floor that did not need opening.

Should I repipe or keep repairing?

Repeat pinhole leaks in galvanized or older copper usually mean the system is telling you what comes next. When repairs start clustering, repiping is the cheaper path. A single isolated failure on an otherwise healthy system is worth repairing.

Tankless or tank water heater?

Tankless saves space and does not run out, but often needs a gas line upsize and a different venting path, so installation costs more. Tank units cost less to install and are simpler to service. Household size and simultaneous demand decide it more than preference.

How is a plumbing job priced?

Access is the big one. A valve behind an open vanity is quick, and the same valve buried in a slab is not. Material choice, fixture count on a repipe, and whether drain lines need work alongside supply all move the number. We scope it in person and hand you a fixed written quote before work starts, so there is no meter running.

Copper or PEX for a repipe?

Both are proven. Copper is rigid and time tested, but it costs more in labor and material, and hard water can still pinhole it. PEX is flexible, faster to install, tolerant of our mineral heavy water, and needs fewer joints inside walls. We run either, and we tell you which one fits your house rather than which one we happen to stock.

How long is the water off during a repipe?

The house stays livable. We run the new lines first while the old system keeps working, then make the changeover, so water is typically off for hours, not days. A whole home repipe usually runs two to four days plus patching, and you get the schedule before we start.

Can you handle the repairs to walls and floors afterward?

Yes. We close up, patch drywall, and restore flooring as part of the same project, so the plumbing repair does not leave you managing three more trades.
