What we fix

Full-service plumbing for Katy homes

One truck, one licensed technician, one upfront price — whether it's a Sunday-night backup or a whole-home repipe you've been putting off.

  • Emergency Drain Cleaning

    Kitchen, bath, and main-line backups cleared with cabling or hydro jetting — plus a camera look at what caused it.

  • Slab Leak Detection & Repair

    Non-invasive detection before anyone touches your foundation. Warm floor spots and a jumping water bill are the tells.

  • Whole-Home Repiping

    Polybutylene, galvanized, and cast iron replacement for Katy's 1980s and 1990s housing stock. Most homes in 2–4 days.

  • Water Heaters & Tankless

    Same-day tank repair and replacement, plus tankless conversions sized to the home rather than to the truck.

  • Toilet & Fixture Repair

    Running, leaking, or busted toilets, faucets, and shut-off valves — repaired properly, not patched to fail again.

  • Water Softeners & Filtration

    Softening and treatment systems built for Katy's hard water and, out west, for well water's iron and sediment.

  • Well Water Plumbing

    Pressure tanks, well pumps, and the supply lines between your well and your fixtures — sized for acreage homes.

  • Sewer Line Repair & Camera

    Camera inspection and repair for original cast iron and clay sewer lines, including root intrusion in mature neighborhoods.

Straight answers

Questions Katy homeowners ask

How does the 60-minute promise work?

Call us and if we don't have a technician at your door within 60 minutes, we owe you 60 bucks. It applies to service calls inside our Katy service area — the dispatcher will confirm your address and arrival window on the phone before we roll.

Are you really open 24 hours?

Yes — 24 hours a day, 7 days a week, 365 days a year. Nights, Sundays, and holidays are handled by the same licensed technicians, not an answering service that calls you back Monday.

How do I know what it will cost before you start?

We quote upfront, flat-rate pricing after diagnosing the problem and before any work begins. You approve the price first. No hourly meter, no surprise invoice at the end.

How do I know if my home has polybutylene piping?

Polybutylene is typically gray or blue-gray plastic pipe, common in homes built from the late 1970s through the mid-1990s. If your Kelliwood, Nottingham Country, or Cinco Ranch home falls in that range, we can confirm it during an inspection.

What are the signs of a slab leak?

An unexplained jump in your water bill, warm spots on the floor, the sound of running water when everything is off, and new cracks in flooring or walls. We confirm with non-invasive detection before anyone breaks concrete.

Do you work on private well systems?

Yes. We service pressure tanks, well pumps, and the plumbing between your well and your home's fixtures, plus filtration and softening built for well water's iron and sediment.

Are your technicians licensed and insured?

Every technician is licensed and insured, background-checked, and works under RMP LIC# 46707. They arrive in a marked Mr. Rooter van with ID.

Need a plumber right now?

Remember our promise: we will be at your door in 60 minutes, or we owe you 60 bucks. Don't wait.
