A leaking pipe rarely stays a small problem for long. What starts as a faint drip behind a wall or under a sink can quietly swell into warped flooring, mold growth, or a spiking water bill before anyone notices.

Our team combines leak detection equipment with hands-on repair skill, so every job ends with a pipe that’s actually fixed, not just quieted down.

Put together, this is why MT Dunn Plumbing is the name Hillsboro residents rely on when a leak needs fixing right.
Fixing a leak properly takes more than tightening a fitting. Here’s how our team approaches every job:
Before touching a single pipe, we ask about water stains, sounds, recent bills, or damp spots you’ve noticed. Your observations often point us toward the leak faster than any tool.
Using acoustic listening devices, thermal imaging, and moisture meters, technicians narrow down the leak’s exact location behind walls, under slabs, or beneath fixtures.
We test system pressure and inspect nearby fittings, since a leak in one spot can sometimes signal wider pressure or corrosion issues elsewhere in the line.
Once the leak is pinpointed, we open only the smallest area necessary, whether that’s a small drywall cut, an access panel, or a section of exposed pipe.
The specific section is isolated so repairs can proceed safely without cutting water to the entire house whenever possible.
Corroded, cracked, or split sections are cut away cleanly, leaving solid, healthy pipe to reconnect to.
Depending on the pipe material and damage, we use soldered joints, push-fit couplings, epoxy sleeves, or full section replacement, whichever holds up best long-term.
Before closing anything up, the repaired line is pressure-tested to confirm the leak is fully resolved and no new weak points were introduced.
Drywall cuts, access panels, or flooring disturbed during the repair are closed up or left ready for your own finishing work, based on your preference.
We walk you through what was found and fixed, and flag any drying, cleanup, or moisture-related follow-up worth addressing.
Most leak repairs in Hillsboro homes are completed in a single visit, typically between 1 and 3 hours depending on access and pipe location.
A leak doesn’t always announce itself with a puddle. Call MT Dunn Plumbing if you notice:
Understanding the cause helps prevent the next leak. Common culprits include:
From what we’ve seen, the honest answer depends on the pipe’s overall condition, not just the one leak in front of you. At MT Dunn Plumbing, we’ve seen how looking beyond the immediate leak saves Hillsboro homeowners from either overpaying for an unnecessary replacement or underinvesting in a line that’s already failing.
A single leak is sometimes an isolated event, and sometimes a warning sign. A young, otherwise healthy pipe with one damaged section is usually a straightforward repair, while a pipe that’s already corroded throughout, or one that’s leaked more than once in the last year, is telling you something bigger is going on underneath the surface. That’s a significant distinction, and time and again, it’s exactly why we look at the full picture before recommending anything.
We’ve been called out to “fix” the same stretch of pipe two or three times for different homeowners who kept patching instead of replacing. In almost every case, the cost of those repeated repairs ended up higher than a single, proper section replacement would have cost from the start.
The cost of repeated patch repairs is minor at first, but it adds up fast compared to a single, proper section replacement done right the first time. We think of every repair as needing to make sense on its own, you’re not just fixing today’s leak, you’re deciding whether you’ll be back here again in a few months.
Homes with aging galvanized steel, old copper with pinhole leaks, or a history of repeated repairs in the same area, in particular, deserve a full look rather than treating each leak as its own separate emergency.
We’ll always repair when repair makes sense, and we’ll tell you honestly when it doesn’t. Our team isn’t interested in selling replacements homeowners don’t need, but we’re just as unwilling to keep patching a line we know is on its way out.
