Slab Leak Detection & Repair in Lake Oswego, OR
A leak under your foundation is one of the hardest plumbing problems to spot and one of the most costly to ignore. Water lines running beneath a concrete slab can crack or wear through for years before you see anything wrong. By the time warm spots or damp flooring show up, water may have been soaking into the soil and slab for a long time. Alchemy Plumbing offers professional slab leak detection in Lake Oswego to help you find the problem early and keep damage to a minimum.
With over 25 years of experience, our team knows local homes inside and out. We work on everything from classic mid-century houses to modern new builds, and we understand how age, soil, and Pacific Northwest weather all play a part in slab leaks. Our goal is simple. We find the leak, show you exactly where it is, and walk you through your options in plain language.
Lake Oswego’s long, wet season keeps the ground saturated for months at a time. When soil stays soaked and then dries out in the summer, it can shift and settle around your foundation. That movement puts stress on the pipes buried under your slab. Homes near Oswego Lake or on sloped lots can see even more ground movement, which makes regular attention to slab plumbing a smart move.

Signs You May Need Slab Leak Detection
Slab leaks often stay hidden, but your home usually gives off a few clues. Here are common signs to watch for.
- Unexplained spike in water bills
- Warm spots on the floor
- Sound of running water
- Damp or warped flooring
- Musty smells near baseboards
- Mold or mildew growth
- New cracks in walls or floors
- Low water pressure
- Water heater running constantly
- Pooling water near the foundation
How Our Slab Leak Detection Process Works
Our slab leak detection process starts with a conversation. We ask about what you have noticed, from rising water bills to warm patches on the floor. Then we check your water meter with all fixtures off to confirm whether water is moving through the system when it should not be. This quick step tells us a lot before we pull out any specialized equipment.
Next, we isolate your plumbing lines to figure out which one is losing water. Hot and cold lines behave differently, and narrowing it down early saves time. Once we know which line is the problem, we start tracing its path under your slab. This lets us focus our search instead of guessing.
From there, we pinpoint the exact location of the leak using non-invasive tools. There is no need to tear up large sections of flooring just to look around. We mark the spot and explain what we found so you know exactly what is going on. You get clear answers before any repair work begins.
Advanced Tools for Accurate Slab Leak Detection
Accurate slab leak detection depends on having the right equipment and knowing how to use it. Our team relies on electronic listening devices that pick up the faint sound of water escaping a pressurized pipe. Even through several inches of concrete, these tools can help us zero in on the source. It is a lot like a doctor using a stethoscope, just built for plumbing.
We also use thermal imaging to spot temperature changes in your flooring. Hot water leaks often leave a warm signature that shows up clearly on a thermal camera. This is especially helpful in Lake Oswego homes during the cooler months, when the contrast between a leaking hot water line and a cold slab is easy to see.
Pressure testing and line tracing round out our approach. Pressure tests confirm a leak exists and help us measure how serious it is. Line tracing equipment maps where your pipes run under the slab, which is useful in older homes where original plans are long gone. Together, these tools give us a full picture without unnecessary digging.
Your Next Steps After Slab Leak Detection
Once we find the leak, we sit down with you and go over your repair options. Every home is different, and the right fix depends on the pipe material, its age, the leak location, and the condition of the rest of your plumbing. We give you a clear, upfront quote so there are no surprises. You decide what makes the most sense for your home and budget.
For a single leak in an otherwise healthy line, a direct spot repair may be all you need. We open a small section of the slab right at the leak, fix the pipe, and restore the area. In homes with older or worn piping, rerouting the line through walls or the attic can be a better long-term choice. This avoids future digging under the slab altogether.
If your home has aging pipes throughout, we may talk with you about a larger repipe. This is common in older Lake Oswego homes where original copper or galvanized lines have been in service for decades. Financing options are available to help make bigger projects easier to manage. Either way, our goal is to stop the leak and help keep it from coming back.

Slab Leak Detection FAQs
What causes slab leaks in Lake Oswego homes?
Shifting soil, aging pipes, and water pressure are common causes. Lake Oswego’s wet winters and dry summers can make the ground expand and settle, putting stress on pipes under your foundation.
How long does slab leak detection take?
Most slab leak detection appointments take a few hours. Larger homes or more complex plumbing layouts may take a bit longer.
Will you have to break up my floor to find the leak?
No. We use non-invasive tools to find the leak first. Any concrete work only happens at the exact leak spot once we have pinpointed it.
Can a slab leak damage my foundation?
Yes. Water escaping under the slab can wash away soil and weaken the support beneath your home over time. Catching it early helps limit that damage.
Do you offer financing for slab leak repairs?
Yes. Alchemy Plumbing offers financing options to help make slab leak repairs and larger plumbing projects more manageable.
