First 10 minutes: actions that save thousands
Water spreads fast. Your goal is to stop the flow, protect valuables, and document what happened.
- Kill the water supply.
- Main shutoff: Turn the valve clockwise until it stops. In many DFW homes, the main is in the front yard meter box or in the garage near the water heater.
- Fixture shutoff: If the leak is isolated, close the angle stops under the sink or toilet.
- Cut power near the leak. If water is near outlets or appliances, switch off the breaker for that area.
- Move valuables and soak up standing water with towels. Use a wet vac if you have one.
- Ventilate and dehumidify. Run fans and open windows if weather allows.
- Document for insurance. Take time-stamped photos and a 30-second video. Note where you first saw moisture.
- Call a licensed plumber for emergency water leak repair if any of the following apply:
- You cannot find or reach the shutoff.
- Water is coming from a wall, floor, or slab.
- You see ceiling bulges, warm spots on the floor, or hear water when fixtures are off.
Pro tip: Keep a valve key or adjustable wrench in a kitchen drawer so you can reach the curb stop fast.
"On Time responded quickly to my call and got someone out quickly. My technician was super friendly and explained everything to me in terms I could understand. Great company!"
How to safely shut off water in North Texas homes
Shutoff locations vary by build year and neighborhood. Many DFW homes are slab-on-grade, so the main shutoff is often outside at the meter box near the curb. Newer homes may have a ball valve in a garage manifold.
- Street-side meter box: Lift the lid. Use a valve key or wrench to turn the valve a quarter or full turn clockwise.
- Water heater area: Look for a ball valve on the cold line. Turn the handle perpendicular to the pipe.
- Individual fixture valves: Under sinks and behind toilets. Turn clockwise.
If a valve is stuck, do not force it. A broken valve can escalate the leak. Call a licensed pro.
"Lily called me to let me know she was rerouting a plumber to come to me immediately and she helped walk me through how to turn my water off, over the phone, to prevent any further damage while I waited on the plumber to arrive. ... The plumber, Ethan arrived and quickly got to work. I had an amazing experience and because of these 2 employees I will forever be using the On Time Experts as my plumbing company."
Spot the source: common leak indicators
You do not need to know the exact pipe to get help fast, but these clues help triage the issue.
- Ceiling or wall leaks:
- Stains, sagging drywall, bubbling paint.
- Often linked to supply lines or upstairs bathrooms.
- Slab or underfloor leaks:
- Warm spots on floors, hissing when fixtures are off, rising water bills.
- Puddles along baseboards or at low points.
- Fixture and appliance leaks:
- Wet cabinet bottoms, corroded supply lines, loose faucet connections.
- Exterior leaks:
- Soggy soil near the foundation, running water at the curb meter when all fixtures are off.
If you suspect a slab leak, reduce foot traffic over the area and avoid turning on radiant or floor heat.
"Chris Miller was so courteous and kind. He found the leak and saved all my bricks. Then he replaced all the pipes under my sink. He did such a great job!"
When to call a pro vs. DIY
Call a licensed plumber immediately if any of these are true:
- Water continues after shutoff attempts.
- The leak is in a wall, ceiling, or under the slab.
- You smell earthy odors or see mold growth.
- You hear constant running water with all taps closed.
DIY can be fine for minor, visible supply line drips under a sink if you are comfortable replacing a braided hose or tightening a packing nut. Anything inside walls or concrete should be handled by professionals. As our site explains, leak detection repair is impossible to carry out by non-professionals.
How professionals find hidden leaks without guesswork
Modern leak detection blends precision instruments with local experience. At On Time Experts, we start with a pressure test to confirm a hidden leak, then use targeted technology to pinpoint the source.
- Acoustic listening: "Most commonly, plumbers use electronic amplification equipment which allows them to listen to water leaks..."
- Thermal imaging: "... thermal imagining cameras that can show temperature variation across the floor..."
- Ground-penetrating radar: "... or ground-penetrating radars that can detect electromagnetic waves."
- Camera inspections: Small high-definition cameras travel inside pipes to reveal cracks, separated joints, or intrusion.
Why it matters: Accurate locating keeps repair cuts small and focused, which reduces cost and disruption.
Slab leaks in Dallas–Fort Worth: what homeowners should know
Many North Texas homes are built on slab foundations. Soil movement and temperature swings can stress buried copper lines, leading to pinhole leaks. Detecting and resolving slab leaks with minimal disruption is our priority. As our site states, "At On Time Experts, we specialize in detecting and resolving slab leaks with minimal disruption to your home."
Typical slab leak signs:
- Increased water bills with no change in use.
- Warm spots on tile or concrete floors.
- Puddles or flooding on the floor, or water stains.
- Hairline cracks in walls or floors.
Once confirmed, we isolate the damaged run and choose the least invasive fix.
"the pros at On time sent there dig crew to cut concrete and dug a tunnel to the leak and fixed the problem"
Repair options: from no-dig to surgical access
Every home is different. We match the method to the problem, the material, and your priorities for speed, cost, and disruption.
- Trenchless and non-invasive methods
- Epoxy pipe lining seals small leaks inside the line. No major excavation. As our site notes, "Many slab leaks can be repaired using non-invasive methods. Modern techniques such as epoxy pipe lining or trenchless repairs allow plumbers to fix leaks without the need for extensive excavation."
- Pipe coating and sectional liners for targeted defects.
- Rerouting lines
- Bypass a compromised slab run by routing new PEX or copper through walls or attic spaces. Often faster and avoids cutting floors.
- Spot repair
- If a single section fails, we make a focused access opening, repair or replace the damaged section, and restore the surface.
- Full replacement
- For recurrent failures or outdated materials, whole-home repipes provide long-term reliability.
We always explain pros and cons, show the access points, and provide up-front pricing before work begins.
Water cleanup and drying basics
Stopping the leak is only half the job. Quick drying reduces mold risk.
- Extract standing water with a wet vac.
- Remove baseboards and drill small weep holes to ventilate wall cavities if saturated.
- Set dehumidifiers and high-velocity fans for 24 to 72 hours.
- Monitor moisture levels until readings normalize.
Document all drying steps for your adjuster.
Insurance and documentation tips
Sudden and accidental water damage is often covered, but policies vary.
- Create a timeline: when you noticed the leak, when you turned off water, when you called a pro.
- Keep photos of damage, meter readings, and any warped materials.
- Save invoices for emergency water leak repair, cleanup, and equipment rentals.
- Ask your plumber for a written locate report with photos and test results.
We work with many insurers and can provide the scope, photos, and repair options they request.
Prevent the next leak: a 15-minute checklist
A few low-cost steps reduce risk, especially in slab-on-grade homes.
- Inspect supply lines
- Replace rubber hoses on washers, fridges, and toilets with braided stainless every 5 years.
- Test your main shutoff twice a year
- Make sure it turns freely. Lubricate or replace if stiff.
- Check irrigation and hose bibs
- Look for soggy spots or dripping vacuum breakers.
- Add leak detectors
- Place smart sensors under sinks, near water heaters, and behind fridges.
- Annual plumbing checkup
- A quick camera and pressure test can catch early issues.
We also offer maintenance plans and service agreements that prioritize prevention. Our contact options include "Inquiry About...* Preventative Maintenance Service Agreements."
