Our Houston plumbers are equipped to handle repairs of every size, from a dripping faucet to a full slab leak. Here’s what we fix:
Not every plumbing problem announces itself loudly. Some of the costliest issues start as small, easy-to-ignore warning signs. If you’re noticing any of the following, it’s time to call Luke’s before a minor issue turns into a major repair:
Houston’s climate, soil, and aging housing stock create plumbing repair needs that show up again and again. Here are some of the most common repairs our team handles across the city:
Pipe leaks range from slow, hard-to-find drips to sudden, high-pressure failures. In Houston, aging galvanized and cast iron pipes in older neighborhoods are frequent culprits, as is freeze damage in exposed pipes during rare but severe cold snaps. Left unaddressed, even a small pipe leak can cause significant structural and mold-related damage over time.
A toilet that runs constantly or leaks at the base is one of the most common plumbing repair calls we receive. In most cases, it’s a worn flapper, a failing fill valve, or a compromised wax ring — all straightforward repairs that make a big difference in water waste and utility costs.
Dripping faucets are easy to ignore but add up fast — a single faucet dripping once per second wastes more than 3,000 gallons of water per year. Worn washers, O-rings, and cartridges are usually the cause, and repairs are typically quick and inexpensive when handled before they escalate.
Because most Houston homes are built on concrete slabs, slab leaks are a real and recurring concern. Houston’s expansive clay soil shifts with moisture changes, stressing the pipes that run beneath or through the slab. Signs include warm spots on the floor, the sound of running water with everything off, and unexplained increases in water bills. Early detection is critical — slab leaks get more expensive the longer they’re left alone.
Hair, grease, soap buildup, and foreign objects cause localized drain clogs that are usually straightforward to clear. When multiple drains are slow at once, or when clogs come back repeatedly, it often signals a deeper blockage or a developing issue in the main drain or sewer line that needs professional equipment to address.
Houston’s hard water accelerates sediment buildup inside water heaters, shortening their lifespan and reducing efficiency. If your water heater is producing inconsistent temperatures, discolored water, or unusual noises, it may need a flush and service — or it may be time to consider a replacement. Our water heater team [Link: calllukes.com/water-heaters/] can help you make that call honestly.

We get it. When something breaks, the instinct is to fix it yourself. A quick search, a trip to the hardware store, and a few hours on a Saturday seems like a reasonable plan. And for some household tasks, it is. But plumbing repair is a category where DIY attempts frequently make things worse, and the reasons go beyond just technical complexity.
Texas Requires Licensed Plumbers for Most Repairs
In Texas, most plumbing work beyond basic maintenance requires a licensed plumber under state law. Unlicensed plumbing work can result in code violations, failed inspections, and complications when you sell your home — even if the repair looks fine on the surface.
The Root Cause Is Usually Not What It Looks Like
A leaking pipe under the sink might be the symptom of water pressure that’s too high, a failing supply line, or a deeper connection issue. Without the right diagnostic approach, DIY repairs often address what’s visible while missing what’s actually wrong — leading to the same problem recurring, or a new one developing nearby.
Water Damage Compounds Quickly
Plumbing mistakes that introduce even a small amount of water into walls, floors, or cabinets can lead to mold growth within 24–48 hours. What started as a manageable repair can become a remediation project if the fix doesn’t hold.
Warranties and Insurance Can Be Affected
Many fixture and appliance warranties are voided by non-professional installation or repair. And if a DIY repair fails and causes property damage, your homeowner’s insurance may deny the claim if unlicensed work is found to be the cause.
It Often Costs More in the Long Run
We regularly get calls from homeowners who attempted a repair themselves and made things worse, sometimes significantly. The cost of a professional repair done right the first time is almost always less than the cost of fixing a DIY attempt that didn’t hold.
None of this is meant to make you feel bad for wanting to handle things yourself; it’s meant to give you the full picture so you can make the right call for your home. When in doubt, a quick call to Luke’s to describe what you’re seeing costs nothing and can save you a lot.

Every plumbing repair comes with a one-year warranty. If something isn’t right after we’ve left, call us; we’ll come back and make it right.
Plumbing repair costs vary depending on the type of repair, the complexity of the job, and the materials involved. At Luke’s, we charge by the hour and provide a clear quote before any work begins, so you know exactly what you’re paying before we start. If the job ends up taking longer than our estimate, your price stays the same. We don’t bill surprises.
For non-emergency repairs, we offer same-day service in most cases. For plumbing emergencies, burst pipes, major leaks, sewer backups, our team is available 24 hours a day, 7 days a week, including weekends and holidays. We don’t charge extra for after-hours service.
Repair makes sense when the damage is isolated — a single section of pipe has failed, a fitting has cracked, or a joint has come loose. Replacement becomes the better option when a pipe is corroded throughout, has failed repeatedly in multiple spots, or is made of a material that has reached the end of its useful life (like aging galvanized steel or deteriorating cast iron). Our plumbers will give you an honest assessment of which option makes more sense for your situation.
Common signs of a slab leak include unexplained increases in your water bill, the sound of running water when everything is turned off, warm or damp spots on your floor, cracks in your walls or flooring, or reduced water pressure. If you’re noticing any of these, don’t wait; slab leaks get more expensive the longer they go undetected. Our leak detection team can pinpoint the issue quickly and accurately.
