Emergency Plumber McKinney TX: Home Sellers

By the McKinney 24 Hour Plumber team · Updated October 2026

What to do first

1. Turn off the water at the main shut-off valve, or at the fixture valve if the leak is in one spot.
2. If water is near outlets or appliances, turn off power to that area at the breaker panel.
3. Take photos and video of the leak, the damage and any wet flooring or walls before cleanup.
4. Move furniture, staging decor and rugs out of the water and start drying the area.
5. Tell your listing agent, and cancel or reschedule showings until the area is safe.
6. Call to be connected with a local plumbing provider who can check availability for your address.

What should I do if I need an emergency plumber in McKinney, TX while selling my house?

Stop the water, protect the house, and get a plumber to look at it. When a pipe bursts or a drain backs up in a McKinney home that is listed for sale, the first job is to shut off the main water valve. Then take photos, start drying, and call to be connected with a local provider who can check availability.

After the water is off, let your listing agent know right away. Showings may need to pause. If you are already under contract, your agent can explain whether the buyer needs to be told about the problem and the repair. Keep every photo, receipt and written quote in one folder. If the leak came from a pipe, our burst pipe repair page explains what usually happens next.

Which plumbing problems count as an emergency during a home sale?

Treat anything that sends water where it should not go as urgent. In a McKinney home on the market, that means active leaks, burst pipes, sewage backing up into tubs or floor drains, a leaking water heater, or no water at all. These problems can cause damage fast and can stall a closing.

• Active leaks: water dripping from a ceiling, wall or under a sink.
• Sewer backups: sewage coming up in a shower, tub or floor drain. See sewer line repair.
• Water heater leaks: water pooling under the tank. See water heater repair.
• Slab leak signs: warm spots on the floor, the sound of running water, or a water bill that jumps.

Can a plumbing problem delay my closing?

Yes, it can. A plumbing emergency during escrow may lead the buyer to ask for repairs, more inspections or a new timeline. The sooner the source is stopped, repaired and documented in writing, the easier it is for both sides to keep moving toward closing.

Buyers usually want to see three things: what failed, what was done, and proof that the area is dry. A written invoice that describes the repair helps. So do before-and-after photos. Your agent or attorney can explain what your contract requires.

What happens during the visit?

A local plumbing provider will inspect the problem, explain the options, and give you a written quote before any work starts. You decide what to approve. For a home that is being sold, ask for the findings and the work in writing so you can share them with your agent and the buyer.

• Inspection: the plumber finds the source, such as a failed fitting, a cracked pipe, a blocked sewer line or a worn water heater part.
• Options: you hear what can be done now and what could wait, and how each choice affects the house.
• Written quote: you get the scope in writing before work begins.
• Paperwork: ask for an invoice that lists what was repaired and where.

No visit length or start time can be promised in advance. It depends on the problem and the provider's schedule.

Should I repair a plumbing problem before listing, or sell as is?

It depends on the problem and your market, but active leaks and backups are usually worth repairing before showings. Buyers tend to discount a home more for an unknown problem than for one that was found, repaired and documented. Your listing agent can help you weigh the choice.

Smaller items, like a running toilet or a dripping faucet, are often simple to handle before photos. See toilet and faucet repair. Bigger items, like a sewer line or a slab leak, may call for a camera inspection or leak detection first, so you know what you are dealing with before you decide.

How do I handle a plumbing item on the buyer's inspection report?

Start by having a licensed plumber look at the item the inspector flagged. Inspection reports often say something like "recommend evaluation by a licensed plumber," and a plumber's written findings help you and the buyer decide whether to repair, give a credit or leave it as is.

Common McKinney inspection items include water heater venting or drain pan issues, slow drains, small leaks under sinks, and signs of a possible slab leak. If a slab leak is suspected, leak detection can help locate it before anyone opens the floor.

Does homeowners insurance help with water damage while my house is for sale?

Sometimes, but it depends on your policy. The Texas Department of Insurance says most homeowner policies cover sudden and accidental water damage, such as a burst pipe or a broken washer hose, but usually not damage from gradual leaks or seepage. Check your policy and document everything.

TDI also advises stopping a leak as soon as possible and says hidden water damage usually must be reported "within days after you first see it." Exact deadlines come from your policy. If the home is vacant while listed, read the vacancy terms in your policy, since they can matter for a claim.

Do I need to tell buyers about mold after a leak?

Ask your agent about what you must disclose, but keep any mold paperwork. In Texas, after a mold remediation project, the contractor must give the client a Certificate of Mold Damage Remediation, and sellers must give buyers copies of certificates received in the preceding five years.

Texas mold work is regulated by the Texas Department of Licensing and Regulation (TDLR). A homeowner can clean up mold in their own home without a license, but larger jobs often involve licensed assessors and remediators. Drying a leak quickly is the most practical step you can take. This is general information, not legal advice.

What McKinney home sellers should know about local plumbing conditions

McKinney sits in the Blackland Prairie, which extends from north of Dallas south to San Antonio. Its Houston Black clay is highly expansive and can "shrink and swell markedly with changes in moisture content," which is one reason buyers and inspectors in Collin County pay close attention to slab leaks and pipe movement. The National Association of Home Builders reports that 97.9% of new single-family homes in the West South Central region were built on slab foundations in 2024, so many newer homes in McKinney, Prosper, Celina and Anna have plumbing under a concrete slab.

Freezes matter too. At DFW Airport, the average first freeze is November 22 and the average last freeze is March 12. During the February 2021 winter storm, insurers reported 21,715 claims in Collin County, covering all insurance lines. If your home in Allen, Frisco or Melissa is listed over the winter, ask your agent who will check it during cold snaps.

To check a plumber's license, the Texas State Board of Plumbing Examiners offers a public license search, and Master Plumber license numbers begin with the letter "M." TSBPE also advises asking your city's plumbing inspection department whether a job needs a permit and inspection. Find more nearby areas on our service areas page.
