Even a Small Leak Can Turn Into a Big Problem Fast

Water damage is one of the most expensive home repairs, and most of it starts with a slow leak.

A leak doesn't have to be a gushing pipe to cause real damage. A slow drip under your kitchen sink, a pinhole leak in a copper pipe behind the wall, or a toilet that runs all night can quietly rack up hundreds of dollars in wasted water and long-term structural damage to your Portland home.

PDX Plumber finds leaks quickly and fixes them right. Nolan brings 25+ years of plumbing experience to every job, and our team is licensed, insured, and ready to show up the same day. Upfront pricing means no surprises: just a clear answer and a reliable fix.

How to Tell If Your Portland Home Has a Leak

You don't need to be a plumber to spot the warning signs.

Some leaks are obvious. You can see water dripping or pooling. Many aren't. Here's how to check whether you might have a hidden leak before calling us:

- **Check your water meter:** Turn off all water in the house, then look at your meter. If the dial or digital display is still moving, water is going somewhere it shouldn't be. - **Look at your water bill:** A bill that's 20–30% higher than your normal usage with no clear reason is a classic sign of a slow leak. - **Check under sinks and around toilets:** Look for discoloration, warping, or moisture on cabinet floors and baseboards. - **Watch for musty smells:** Mold and mildew grow fast in damp hidden spaces. If something smells off near a wall or under a floor, trust it. - **Listen at night:** Running water sounds when everything is off usually means a toilet valve leak or a pressurized pipe leak.

If any of these match what you're experiencing, it's time to call. The longer a leak goes unaddressed, the more it costs to fix.

Every Type of Residential Leak We Repair in Portland

If water is going somewhere it shouldn't, we can track it down and stop it.

PDX Plumber handles the full range of household leaks that Portland homeowners deal with:

- Faucet and fixture leaks (kitchen, bathroom, utility) - Pipe leaks behind walls, under floors, and in crawl spaces - Toilet base leaks and internal valve leaks - Leaking water heater connections and pressure relief valves - Leaking supply lines under sinks - Outdoor hose bib and irrigation leaks - Leaking garbage disposal seals and connections - Slab leaks (pipes leaking beneath your home's concrete foundation)

Slab leaks deserve a special mention: they're harder to detect but cause serious structural damage if left alone. Signs include warm spots on your floor, cracking drywall, and a water meter that won't stop moving even with everything turned off.

How PDX Plumber Diagnoses and Fixes Your Leak

No guesswork, no unnecessary demo work. Just a clear diagnosis and a fast fix.

When we arrive, we start by isolating the problem. We use pressure testing, visual inspection, and in some cases non-invasive detection methods to locate leaks without tearing into your walls unnecessarily. Once we know exactly what we're dealing with, we give you a clear, upfront price and get your approval before touching anything.

Most leak repairs are completed in a single visit. We carry common repair materials on our vans, copper fittings, PEX tubing, supply line replacements, and more, so we're not making extra trips for parts. After the repair, we test everything to confirm the leak is resolved and the system is holding pressure correctly.

Frequently Asked Questions

What is a slab leak and how do I know if I have one?

A slab leak is a pipe leak beneath the concrete foundation of your home. Signs include warm or wet spots on your floor, higher-than-normal water bills, cracking in walls or flooring, and a water meter that keeps moving with everything off. Slab leaks require prompt attention. PDX Plumber can diagnose and repair them.

Do you offer same-day leak repair in Portland?

Yes. Same-day service is available for most leak repair calls, and you save $50 when we come out same-day. Call early in the day for the best availability. We arrive on time, in uniform, and with the materials to handle most repairs right then.

Can a leaking pipe cause mold in my home?

Yes, and it happens faster than most people expect. Mold can begin growing within 24–48 hours of moisture exposure in a dark, enclosed space like a wall cavity or cabinet floor. Fixing the leak early is the most important step in preventing mold from becoming a secondary problem.

How much does leak repair cost in Portland, OR?

It depends on the leak type and location. A simple supply line replacement might run $100–$200. A pipe leak inside a wall costs more because of access work. PDX Plumber gives you a firm upfront price before any work starts, so you know exactly what to expect. New customers also save 5% on their first visit.

How do I find a hidden water leak in my Portland home?

Start by checking your water meter with all water in the house turned off. If the meter is still moving, you have a leak somewhere. Also check under sinks, around the base of toilets, and near your water heater for moisture or discoloration. If you can't locate it visually, call PDX Plumber: we have the tools to find leaks without unnecessary demolition.
