What we do
From a pinhole in a copper line to a leaking supply under the vanity, we track down where the water is actually coming from and repair it right — not just patch the spot where it shows up.
Leak Repair in Mount Juliet homes
In Mount Juliet's newer homes, many leaks trace back to the same few spots: a supply line under a sink, a fitting on the water heater, or a crimp connection in PEX that was never fully seated. A higher-than-normal water bill is often the first clue.
Mount Juliet is our home base, so we can usually reach you quickly.
Calls we get from Mount Juliet
Water bill suddenly higher
We check toilets, fixtures, and visible lines to track down the leak.
Damp sink cabinet
Usually a supply line or drain connection. We fix it before the cabinet floor is ruined.
Drip at the water heater
We check fittings and the relief valve to find the source.
A tip from Will Pontius
Check your water meter with everything off. If it's still moving, there's a leak somewhere.

Why it matters
Water always finds the lowest point. Finding the real source is what stops the damage from spreading.
Common causes of leak repair problems
Pinhole leaks in copper
Over time, water chemistry and age can wear tiny holes in copper pipe. They often start as a slow drip that's easy to miss.
Failed fittings and connections
Compression fittings, supply connections, and old solder joints are common weak points, especially under sinks and behind appliances.
Fixture and drain leaks
Leaks around tubs, showers, and drains can soak into walls and floors before you see any sign of them.
Aging galvanized pipe
Older homes with galvanized steel pipe can corrode from the inside, leading to leaks and rusty water.
How we diagnose leak repair problems
Water travels along pipes and framing before it shows up, so a stain is rarely right under the leak. On leak repairs in Mount Juliet, we trace the water back to its source, check your meter for hidden leaks, and look at nearby connections that could fail next. Then we explain the repair and the price before starting.
Your leak repair options
Spot repair
Replacing a failed fitting or short section of pipe at the source.
Section replacement
When a run of pipe has multiple weak spots, replacing that section is the more lasting fix.
Fixture leak repair
Resealing or repairing the leaking fixture, valve, or drain connection.

What affects the price
You get the price before we start — no surprises. These are the things that move it:
- •Where the leak is and how easy it is to reach
- •Pipe material and condition
- •Whether the leak is on supply or drain lines
- •Length of pipe needing replacement
Prevention tips
- ✓Check under sinks every few months
- ✓Watch your water bill for unexplained jumps
- ✓Know where your main shutoff is
- ✓Replace old supply lines before they fail
