Plumbing Services in Northeast Texas

Leaky faucet, running toilet, no hot water, or a pipe that let go inside the wall? Underwood’s licensed plumbers fix it across Collin, Grayson, Fannin, Hunt and Lamar counties, from our offices in McKinney, Bonham and Sherman.

Plumbing Emergency? We Answer Day or Night.

Burst pipe in the evening, or a water heater that quits on a Holiday, we’ll get a truck rolling.

Our Plumbing Process

Call or request a quote: We pick up nights and evenings included, we’ll get a plumber on schedule.

Find the cause: We track down what is actually failing, with a camera on drain and sewer lines when the job calls for it.

Explain your options: You hear what’s wrong and what it takes to fix it before any work starts.

Fix it in one trip: Our vans carry the parts for the jobs we get called on, so most repairs finish on the first visit.

Test the work: We run water, check for leaks and make sure everything works before we pack up.

Leave it clean: The work area gets cleaned up before we head out.

Signs It's Time to Call a Plumber

Slow drains: the sink or tub still holds water minutes after you shut it off.
Running out of hot water: showers go cold early, or the water comes out rusty.
A toilet that won't stop running: it's wasting water every hour it runs.
Low water pressure: weak flow at more than one tap can point to a supply line problem.
Stains, damp spots or a musty smell: often a hidden leak inside a wall or ceiling.
A water bill that jumped: with no change in how you use water, something is leaking.

We send plumbers to homes and businesses in McKinney, Allen, Prosper, Sherman, Denison, Bonham, Greenville, Paris and the towns in between.

 Trustindex verifies that the original source of the review is Google. I needed a sewer tank cover replaced due to it being hit by the lawnmower. These guy fixed it in less than 30 minutes.
Chad also suggested putting landscaping stuff around the 4 tanks to prevent this happening again. Totally happy with their service.
