Before Katy’s population boomed in the early 2000s with the development of neighborhoods like Cinco Ranch and Grand Lakes, John Moore plumbers were serving residents of Old Katy.

Today, we are proud to provide our plumbing services to homeowners all across Katy and the Greater Katy Area, from clearing drain clogs to repiping homes to repairing main line sewer lines. Whether you’ve been a Katy resident for generations or just moved there in the past 10 years, John Moore knows that Katy homeowners- new and old- value their families and the quality of life their home provides them.

Unfortunately, as your home’s plumbing system ages, you might find that your home isn’t providing the same quality of life that it used to. Rust in your home’s galvanized pipes can lead to leaks that damage your walls and brown-tinted water coming out of your faucets; a main line blockage may send waste water back up through a tub drain in your home; and the quality of your home’s potable water may not be the best because- let’s face it- Houston’s water quality has never been the best.

If you find that your home’s plumbing is affecting you and your family’s quality of life, you can count on John Moore’s certified plumbers to restore comfort in your home

Rusted Galvanized PipePVC PipingPEX Piping

Water Repiping for Katy, Texas Homes; a Common Solution for Broken PVC, Leaky Copper and Rusty Galvanized Pipes

Many homes in Katy still use galvanized or PVC pipes to distribute potable water to drink, cook, wash with, and bathe in. Over time, both galvanized and PVC pipes will run into issues.

After only about 5 or 10 years of use, galvanized pipes will start to rust from the inside out. Most of the time, the rust will eat way at the pipe until it makes a little pin-hole through the pipe where water will leak onto your ceiling and walls. These little holes can become clogged with rust, leading to reddish-brown marks or “scabs” on the outside of your pipe that will give way to larger leaks if not addressed. PVC pipes, on the other hand, rely on joint connections that can burst open after years of being under pressure.

If you notice water marks, rust-tinted water, or low water pressure in your home, it may be time to consider a horizontal or whole-home repipe. The difference between a horizontal repipe and a whole-home repipe is that during a horizontal repipe, our plumbers will only repipe the pipes that run in your attic, while in a whole-home repipe, they replace every pipe in your home. A whole-home repipe is the better solution in the long term because we will replace your home’s old galvanized or PVC potable water distribution system with PEX pipes. Unlike galvanized pipes, PEX doesn’t rust or decay. And because PEX piping is flexible and uses ProPEX® expansion fittings, you’ll never have to worry about bursts or ruptures. John Moore even includes a 25-year product warranty and a 10 year labor warranty* on whole-home repipes!

Ready to upgrade your home’s pipes to PEX? Schedule a consultation or call us at 877-730-2525!

*Excluding damages that result from lightning, flooding, and other acts of God or vandalism.

Main Line SewerSewer Line

Waste and Sewage in Tubs and Showers Cause for Main Line Sewer Repair in Katy, Texas Homes

One of the biggest home horrors is the smell and sight of waste-water coming back up through a tub or shower drain.

This gross and unsanitary phenomenon is caused by a blockage in your home’s main sewer line, so that instead of your waste and greywater going down the tube to your city’s sanitation center, it comes back up into your home because it has nowhere else to go. If your showers and tubs are all on the second story of your home, then you may notice a strange gurgling sound coming from your downstairs toilets, which is the sound of air pockets in your clogged sewer coming up through your toilet.

In either case, a main line blockage is something that should be addressed as soon as you suspect you have one, because it can lead to some nasty consequences and costly damage to your home. John Moore’s solution to a main line blockage is to run an extra-strength plumber’s snake down your main line’s access point to poke a hole in the clog. After we allow some water to drain, we can then run a camera down the drain to identify the cause of the blockage. The four things that cause most main line stoppages are: a dip in your main line, offset concrete pipes, a rotted-through cast iron main line, and tree roots. Once we determine the cause and location of the blockage, we can then provide you with the best solution to prevent your main line from being clogged again, whether it’s a tunnel repair, spot repair, reslope, reroute, or completely replacing the main line.

What Our Customers Say

John Moore Licensed Technicians

Hear what our customers are saying about our employees and our service.


David Lawrence with John Moore managed the team and took care of my home during the complete repiping of my home. He treated my home with loving care, and responded to me so quickly. He recognized problems, and contacted me in regards to issues as he discovered me, and texted me every day when he arrived and when he left. He showed up on a Saturday when I was freaking out, and he took care of all the small issues that arise when you have a contractor lead.

Troy Watts was AMAZING to work with, very knowledgeable and professional. I asked a lot of questions and he was patient and made sure we were fully comfortable with the path forward. We had a great experience and I would highly recommend them.
