The short answer
Shut off the Water
Before you touch anything, locate the shutoff valve for the leaking pipe. In many homes, this is under the sink or near the water heater. Turn the valve clockwise until the water stops. If you cannot find a valve, shut off the main water supply to your home. Knowing where this valve is before an emergency saves you from a bigger mess.
Assess the Leak Type
Look closely at the leak to determine its source. A pinhole leak in a copper pipe may only need a simple patch, while a cracked joint or corroded section might require replacing part of the pipe. Also check for signs of water damage like stained drywall, bubbling paint, or damp wood. These clues tell you how long the leak has been active.
If the leak is behind a wall or under the floor, you may not see the source. Water can travel along framing and appear far from the actual break. In that case, you need leak detection equipment to find the exact spot. Local water damage pros have moisture meters and thermal cameras to locate hidden leaks without tearing out large sections of your home.

Temporary Pipe Repairs
For a small, accessible leak, you can apply a temporary fix to stop the water flow. A pipe repair clamp is a metal sleeve with a rubber gasket that you tighten over the leak. Epoxy putty also works for small pinholes and cracks. These fixes are not permanent, but they give you time to plan a proper repair.
Clean and dry the pipe surface before applying any patch. Sand the area lightly to help the material adhere. Follow the product instructions carefully. Remember that these are stop-gap measures. A professional repair is still needed to replace the damaged section or joint, especially if the pipe is old or corroded.

Apply epoxy putty to small pinholes
Wrap rubber tape around a leaking joint
Tighten any loose fittings with a wrench
Keep a bucket under the leak while you work
When to Call the Pros
Some leaks are beyond a simple fix. If the pipe is inside a wall, under a concrete slab, or behind cabinets, you need specialized tools to access it. The pros use leak detection equipment to find the exact source without unnecessary demolition. They also have industrial dryers and dehumidifiers to dry out the affected area thoroughly.
Water damage from a pipe leak can lead to mold growth and structural rot if not dried quickly. Pros can extract standing water, dry the framing, and map moisture levels to ensure everything is dry. They can also help with drywall repair and repainting after the pipe is fixed. If you are unsure about the extent of the damage, a professional inspection is a wise step.
Leak is behind a wall or under the floor
Water has soaked into drywall or wood
You see signs of mold or musty odors
The pipe is old, corroded, or has multiple leaks
You cannot find the source of the water
Prevent Future Leaks
After fixing a leak, take steps to prevent another one. Insulate pipes in unheated areas to avoid freezing in winter. Check pipe joints and fittings regularly for signs of wear. In areas with hard water, mineral buildup can corrode pipes from the inside, so consider a water softener if that is a concern.
If you live in Rowlett, keep the location of your main shutoff valve written down and share it with your household. Also, know how to turn off the water to individual fixtures like toilets and washing machines. Regular maintenance, such as replacing worn washers and tightening loose connections, can catch small issues before they become major leaks.
Insulate exposed pipes in cold areas
Inspect pipes monthly for rust or moisture
Replace worn washers in faucets and valves
Know the location of your main shutoff valve
Consider a water leak detection system

Can I fix a leaking pipe myself?
You can fix a small, accessible leak with a repair clamp or epoxy putty as a temporary measure. For leaks inside walls or under floors, you need professional equipment to locate and dry the area. Attempting a permanent repair without experience can lead to bigger problems.
How long does a pipe repair take?
A simple clamp repair can take less than an hour. But if the leak is hidden or requires replacing a section of pipe, the job may take several hours or more. The drying process for water damage can take days, depending on the extent of the soak.
Is water damage from a leaking pipe covered by insurance?
Policies vary, and your insurer decides what is covered. Many homeowners policies cover sudden, accidental water damage, but gradual damage from poor maintenance is often excluded. Check your policy and document the leak with photos and notes. If in doubt, ask your insurance company directly.
