Code-compliant plumbing, measured before it is quoted
From hidden pipe leaks and slow main drains to tankless water heaters and whole-home repipes, Trueline Plumbing Works reads your system first, then puts an upfront flat-rate price in writing and arrives with a stocked truck.
What we check on a copper repair
- 01 Torch flame held on the shoulder of the fitting
- 02 Copper supply pipe above the joint
- 03 Solder seam at the cup of the fitting
- 04 Isolation valve upstream of the work
Every repaired joint is static pressure tested before the water is restored, and the upstream valve is checked so the run can be shut off again in seconds.

Stocked trucks, flat rates, no commission
Our plumbers are salaried trade professionals, never commission salespeople. A visit starts with readings: static pressure at the main, flow at two fixtures and the meter watched with every outlet closed, all written down before a part is priced. The truck carries Type L copper, Uponor PEX-A fittings, brass quarter-turn valves and an HD sewer camera, so most repairs finish in one visit, with drop cloths down and the workspace swept before we leave.

Service coordinator
Runs the dispatch desk: confirms the symptom, the postcode and where the main shut-off sits, then books a two-hour arrival window and sends a heads-up before the truck arrives.
What homeowners tell us
-
Water was dripping through the kitchen ceiling from the upstairs bath line. A moisture meter found the pinhole above the pantry, one small square of drywall came out, and a new copper section was sweated in the same morning. The pressure check also caught a failed regulator.

Our twelve-year-old tank had started weeping rust. Deshawn checked the gas line capacity before quoting, then fitted a wall-mounted condensing tankless unit with every vent and service valve labelled. Back-to-back showers no longer run cold.
M. Castellanos · Tankless water heater · March 2026

Our 1960s house had rusty water every morning and a shower that dropped to a trickle. Marcus walked us through every pipe run and gave us a flat quote, and the crew repiped the house in two days, with water back on before dinner on the first night.

Homeowner questions
Do you charge by the hour or quote a flat rate?
Flat rate. The $145 diagnostic fee covers the stocked truck, troubleshooting and a firm written quote, and it is credited towards any repair you approve during the visit.
What should I do right now about an active pipe leak?
Close the main shut-off, open a downstairs cold tap to relieve the pressure, switch off the water heater if hot lines are affected, and call the dispatch desk for a priority same-day slot.
Should I repair or replace my water heater?
A tank under eight years old with one failed part is usually worth repairing. At 10 to 12 years or more, or with rust leaking from the inner vessel, replacement is the only safe fix.
Do you pull municipal permits for water heaters, gas lines and repipes?
Yes. Wherever code requires one, our master plumber files the permit and coordinates the final inspection as part of the quoted project.
