Water Leak Detection & Repair in Beaverton, Oregon
A hidden water leak can run for months before you see any visible damage — and by then, the mold, rot, and structural damage are already well underway. True Flow Plumbing PDX locates and repairs leaks in Beaverton homes using pressure testing and acoustic detection, without tearing your house apart to find it.
Leak Detection for Beaverton Homes
Beaverton has one of the widest ranges of housing ages in Washington County — from 1950s ranch homes in Cedar Hills and Raleigh Hills with original galvanized plumbing, to 2000s construction in Murrayhill and Bethany with copper or early PEX. Older homes develop pinhole leaks in galvanized lines and corroded copper fittings. Newer homes more commonly see supply line failures under fixtures or slab leaks from improperly installed copper fittings. We use acoustic and thermal detection to find leaks without opening walls unnecessarily.
🔍 Hidden Pipe Leaks
Supply line leaks inside walls, under floors, or in crawl spaces — found with pressure testing and acoustic equipment, not guesswork.
🏠 Slab Leaks
Pipes that fail beneath a concrete slab are one of the most damaging leaks in any home. We locate the exact spot before we touch the concrete.
📍 Pinhole Leaks
Pinhole leaks in galvanized, copper, and early PEX are common in 1950s ranch homes through 2000s planned developments. They weep slowly — barely noticeable until the drywall is soaked or mold appears.
🚿 Fixture & Supply Line Leaks
Leaks at shutoff valves, supply lines under sinks and toilets, and fixture connections — diagnosed and repaired in one visit in most cases.
💧 Main Line Leaks
A leak in the service line between the street and your house can go undetected for months. Signs: wet yard, high water bills, low pressure everywhere.
🌡️ Thermal & Acoustic Detection
We use acoustic listening equipment and thermal imaging to find leaks without invasive opening of walls or floors before we know where the problem is.
Signs You Have a Hidden Leak in Your Beaverton Home
- Water bill is higher than usual with no change in usage
- Sound of water running when all fixtures and appliances are off
- Wet, soft, or discolored spots on walls, ceilings, or floors
- Mold or mildew smell without any visible water source
- Low water pressure throughout the house
- Warm or hot spots on the floor (slab leak indicator)
- Your water meter is spinning with everything shut off
How We Find Leaks in Beaverton Homes
- Pressure test the supply system to confirm an active leak and isolate it to hot or cold lines
- Acoustic listening equipment to hear water escaping through pipe walls, even under concrete
- Thermal imaging to spot temperature differentials caused by wet materials behind walls
- Isolate sections of the system to narrow down the location before opening anything
- Provide a written summary of what we found, where it is, and what it costs to repair
Beaverton Neighborhoods We Serve
We Find It, Then We Fix It
Detection is only half the job, and a lot of leak calls end with someone handing you a location and a separate number to call. We locate the leak and repair it on the same visit wherever the repair is within plumbing scope.
Supply line leaks
Pressurized lines inside walls, ceilings, or under floors. These are the ones that do damage fast, and they’re what a pressure test plus acoustic location is built to find.
Slab and underground leaks
A warm spot on the floor, a running meter with everything off, or an unexplained jump in your water bill. Locating these accurately is what keeps the repair small instead of exploratory.
Fixture and valve leaks
The undramatic ones — a failing angle stop, a supply line at a toilet, a hose bib that weeps. Cheap to fix, expensive to ignore inside a wall or cabinet.
Water heater leaks
If it’s coming from a fitting, it’s a repair. If it’s the tank body, it isn’t repairable — see water heater service in Beaverton →.
Gas leaks
Different job, different urgency. If you smell gas, leave and call NW Natural first. Then see gas line repair in Beaverton →.
Sewer and drain leaks
Water where it shouldn’t be isn’t always supply-side. A cracked drain or sewer lateral shows up as damp, odor, or settling — see sewer camera inspection →.
What Leak Detection Costs in Beaverton
Locating a leak is billed as labor, and the repair is quoted once we know what and where it is. Estimates are free.
- Mon–Fri, 8am–4pm — $185/hour + parts & materials
- Mon–Fri, before 8am or after 4pm — $462.50 minimum (call-out + first hour), then $185/hour
- Saturday & Sunday, all day — $462.50 minimum (call-out + first hour), then $185/hour
The reason to call early rather than watch it: with a hidden leak, the water damage is almost always more expensive than the plumbing repair. A stain that’s spreading is not a wait-and-see situation.
Catching the Next One Before It Spreads
Most of the Beaverton leaks we chase were running for weeks before anyone noticed. That is the real cost of a hidden leak — not the repair, but the time it had to do damage. If you would rather not rely on spotting a stain, a smart water monitor and automatic shutoff watches flow and pressure at the main and closes the valve on its own when something is clearly wrong. Worth considering once you have been through one.
Frequently Asked Questions
How do you find a hidden water leak in a Beaverton home?
We start with a pressure test to confirm an active leak in the supply system, then use acoustic listening equipment to narrow down the location without opening walls or floors until we know exactly where to cut. This saves you from unnecessary demolition and repair costs.
What are the signs of a hidden pipe leak in Beaverton?
A water bill that jumped without a change in usage, the sound of running water when everything is off, wet spots on walls or ceilings, a mold smell without visible water, and unexplained low pressure are the most common signs. Any one of these is worth a call.
Do you repair the leak the same day you find it?
In most cases yes — we come prepared to both locate and repair. Simple pipe repairs and fitting replacements are handled the same visit. More involved slab leak repairs may require a follow-up, but we'll tell you exactly what you're looking at before we schedule anything.
Does homeowner's insurance cover leak detection and repair in Beaverton?
Most policies cover sudden and accidental pipe failures, including the cost of accessing the leak (opening walls, cutting into a slab). They typically don't cover gradual leaks that went unreported. Document everything and call your insurance company as soon as you discover a leak — we can provide a written report of our findings if needed.
How much does leak detection cost in Beaverton?
Leak location is billed at our published labor rate — $185/hour plus parts and materials Monday to Friday 8am-4pm, or a $462.50 minimum covering call-out and first hour then $185/hour after hours and weekends. The repair itself is quoted once we know what failed and where it sits. Estimates are free. Most residential leaks are located well within the first hour.
Do you handle roof leaks?
No. If water is coming in from above during rain, that's a roofing problem, not a plumbing one, and a roofer is who you want. We handle leaks in pressurized water lines, drain and sewer lines, fixtures, valves, and water heaters. If you're genuinely unsure which you have — ceiling stains can come from either — describe it when you call and we'll help you work out who to ring before anyone charges you for a visit.
What about a gas leak?
Treat that as an emergency, not a detection job. Leave the house without flipping any switches, then call NW Natural from outside to shut off the supply. Once it's safe, we locate and repair the gas line and handle the permit, pressure test, and inspection. See our gas line repair page for Beaverton for how that process works.
How do you find a leak without tearing up walls or floors?
We start with a pressure test to confirm there's an active leak in the supply system at all, which rules out condensation and drainage issues that get mistaken for leaks. From there acoustic listening equipment narrows the location, since pressurized water escaping a pipe makes a distinctive sound through slab and drywall. The point of locating accurately is to open one small area rather than several exploratory ones.
My water bill jumped but I can't see anything. Is that a leak?
Often yes, and there's a check you can run before calling anyone. Turn off every fixture and appliance that uses water, then look at your meter — if it's still registering flow, water is going somewhere it shouldn't. A silently running toilet flapper is the most common and cheapest culprit. An underground or slab leak is the one worth finding quickly.
