What We Install and Repair

  • Kitchen and bathroom faucets, including pull-down, single-handle and widespread styles.
  • Toilets, from a new comfort-height toilet to a rebuild of the one you have.
  • Sinks in the kitchen, bathroom, laundry room or bar.
  • Garbage disposals, installed, replaced or repaired.
  • Shutoff valves under sinks and behind toilets.
  • Tubs, shower valves and shower heads.
  • Outdoor faucets and hose bibs, including frost-free styles that stand up better to a North Texas freeze.

Bought It Yourself? We'll Put It In

Plenty of customers pick out their own faucet or toilet and call us to install it. That's fine with us. If a part turns out to be broken or missing, your plumber will tell you before going further. One customer's new toilet arrived with a broken part, and we had the part on the van, so it went in that day.

Repair or Replace?

Lots of fixtures can be repaired. Worn stems and cartridges in a dripping faucet can be replaced, and a running toilet often needs only new parts inside the tank. It's usually time to replace a fixture when the same leak keeps coming back, when porcelain is cracked, or when corrosion has eaten into the finish and the parts. We'll tell you which way we'd go and why, and give you the price for each.

Older Homes and Hard-to-Find Parts

Older fixtures sometimes need parts that aren't on any van. When that happens, we go get them from the supply house and come back to finish the job.

"Stellar experience with Koen Plumbing today. Needed new shutoff valve under my sink. Had Koen here first thing this morning and got it taken care of. They were able to respond within 24 hours. Alphonso and Adrian were polite and efficient and I very much appreciated them."

  • "Arrived promptly. We had purchased our toilet and faucet and a part of the toilet was broken. Instead of having to return it to the place where we purchased it, they had a part in their truck and made the repair and installed the toilet. They went above and beyond what they needed to do!"

  • "Mario and his helper arrived on time, asked what was needed and prepared a quote. They then proceeded to replace stems in three sets of faucets and rebuild a toilet. They were friendly, efficient and most knowledgeable. When they needed to go to the supply store for older parts, they returned quickly."

    "I now know who will replace our water heater, which is aging, and I have found my plumber. Thank you Mario."

Frequently Asked Questions

Will you install a faucet or toilet I bought myself?

Yes. We install fixtures you've bought, and we'll let you know before we start if anything in the box is damaged or missing.

My faucet drips. Does it need replacing?

Not always. A drip is often a worn stem or cartridge, which we can replace. If the faucet keeps leaking after repairs or the body is corroded, we'll recommend a new one.

Why does my toilet keep running?

Usually a worn flapper or fill valve inside the tank. Both are quick, inexpensive repairs, and we'll check for anything else while we're there.

Can you replace a shutoff valve under my sink?

Yes. It's one of the most common small jobs we do.
