Lawrenceville Slab Leak DetectorsSigns of a Slab Leak: 10 Signs Checklist
Have this problem now? Call us.
A slab leak rarely fixes itself, and the longer water runs under concrete, the more it can wash out soil and lift flooring. One call gets you detection first — before anyone opens your floor. Call Lawrenceville Slab Leak Detectors at (770) 520-8128.

The working photo on this page is an illustrative working photo, not a photo of a specific job at a specific address. The diagrams are schematics, not to scale, made to explain the signs, process, options, or costs on this page in plain words. Call us at (770) 520-8128 if you are unsure what you are seeing.
Do you have this problem? Call us now
If you have this problem now, call us at (770) 520-8128 first. This page explains signs of a slab leak: 10 signs checklist, but a call gets you detection, a fix, and a written price after inspection. Do not wait for the leak to get worse while you read.
Watch for 2+ signs together: bill jump, running-water sound, warm floor, damp floor, low pressure, or new cracks. One sign alone does not prove a slab leak — a meter test is the next check.
The points this guide covers are: all 10 signs, 1-vs-2+ rule, meter test next step, non-slab lookalikes (running toilet). Each point matters because it changes what you should do next, whether you should call now, or whether a simple check will rule something out first.

What to do next: call us and fix it
If you are reading this because something is wrong in your home, the next step is simple: call us. This guide explains what to look for, but only a detection visit can confirm it and fix it.
If you remember one rule from this guide, remember this: confirm before you cut, and pinpoint before you repair. A guess that opens the wrong floor costs time and money, and it does not fix the leak.

Check this now, then call us
Use this list to check now, then call us. A guide cannot see your home, your pipes, or your meter. Only a detection visit can confirm it, and that is the step that actually fixes the problem.
- Check for two or more signs together, not one alone
- Rule out simple causes first, like a running toilet
- Do a meter test where it fits, and note hot versus cold
- Call for detection if signs persist or water damage is growing

Call Us: (770) 520-8128How this helps you in Lawrenceville, GA: call us and fix it
In Lawrenceville, red Georgia clay, copper pipe from 1960 to 1990, galvanized pipe near downtown, and polybutylene in Collins Hill and Hurricane Shoals subdivisions all shape what kind of leak is most likely. Lawrenceville Utilities runs the city's water, so your meter and bill come from the city, and a street-main issue is the city's job.
That is why we explain it in plain words, so you can decide with confidence.
Also see: areas we serve in Lawrenceville.
When to call us now
If the signs are growing, if water is pooling, or if flooring is lifting, shut off your main water first, then call us. If the signs are slow and single, a meter test is a good next step, and a detection visit is the next step after that.
Do not ignore a leak for weeks. Water under a slab can wash out soil, warp flooring, and create the right conditions for mold. Early detection is cheaper and less disruptive than a late repair.

Do not wait, and do not guess
The most common mistakes are: assuming one sign proves a slab leak, cutting a floor without pinpointing first, choosing a repair based on price alone without knowing the pipe condition, and waiting until flooring is ruined.
Another mistake is treating a sewer leak like a supply leak, or a cold-water leak like a hot-water leak. The signs, the test, and the fix are different, and detection is what tells them apart.

More on signs and causes
These pages cover the same topic, so you can compare options without guessing.
What to tell us when you call
Read the guide, then call with what you found. Tell us:
- The signs you see: bill jump, warm floor, running-water sound, low pressure, or damp flooring
- Whether the floor is warm in one spot, and whether water is pooling or flooring is lifting
- Your meter-test result, if you ran one, and your ZIP and street in Lawrenceville
Detection comes first, before any floor is opened. Start with slab leak detection, then the repair that fits, at a written price after inspection. Call (770) 520-8128.
Signs at a glance: how fast to act
| Sign you see | What to check first | How fast to act |
|---|---|---|
| Bill jump with no usage change | Water meter test | Call for detection |
| Warm floor spot | Hot-water line check | Call for detection |
| Running-water sound with taps off | Acoustic listening | Call for detection |
| Low pressure all over the house | Pressure and isolation testing | Call for detection |
| Damp or warped flooring | Detection before any floor is opened | Call for detection |
| Water pooling or flooring lifting | Shut off your main water if you can do so safely | Call now |
Two or more signs together are a much stronger reason to call than one sign alone.
Is it actually a slab leak?
Not every bill jump or damp spot is a slab leak. These mimics are worth ruling out before any floor is opened:
| Symptom | Could also be | How to tell apart |
|---|---|---|
| Bill jump | A running toilet, or a city-side issue | Water meter test, then detection if water loss continues |
| Damp flooring | A drain leak, not a supply leak | Detection pinpoints whether the leak is supply or drain |
| Cracks in walls or floors | Foundation movement without a leak | Detection confirms whether water is present under the slab |
If you are unsure, detection answers it. Do not guess at a repair under concrete.
Why the wet spot is rarely above the leak
- Pipe breaks under the slab - water escapes under concrete, where you cannot see it.
- Water travels sideways - it follows gravel, soil and gaps under the slab, away from the break.
- Wet spot appears elsewhere - flooring feels damp or warm some distance from the actual leak.
- Detection pinpoints the break - acoustic listening and thermal imaging find the source, not just the wet spot.
That is why opening the floor at the wet spot, without detection, can miss the leak.
