Bathroom leaks found without tearing up tile.
Bathtub Leak Detection McLean VA
A slow tub leak can soak a subfloor for months before you notice. Our bathtub leak detection in McLean, VA pinpoints the exact source — drain, overflow, faucet or grout — so repairs stay small and tile stays intact.
What's included
What Our Bathtub Leak Detection Includes
Our bathtub leak detection covers dye-testing of drains, moisture mapping behind tile, and a clear report showing exactly what failed.
Drain & Overflow Testing
We dye-test tub drains and overflow gaskets to confirm exactly where water escapes, instead of guessing and opening walls.
Tile & Grout Inspection
Moisture meters read behind tile and around fixtures, catching slow seepage that hasn't stained anything yet.
Faucet & Valve Checks
We check tub faucets, diverters and shutoff valves for drips that run inside the wall where you can't see them.
Clear Repair Plan
You get photos of what we found and a straight explanation of the fix — no jargon, no upsell.
Service overview
Understanding Bathtub Leak Detection McLean VA
Bathtub leaks rarely announce themselves. By the time paint bubbles or the ceiling below stains, water has usually been traveling for weeks. Our bathtub leak detection finds the entry point early, while the fix is still simple.
Many McLean bathrooms — especially in older Chesterbrook homes with original tile — develop leaks at the tub-to-wall joint or behind aging grout. We serve homes across 22101 and 22102, and our technicians know the common failure points in both vintage and remodeled bathrooms.
The service timeline
Our Bathtub Leak Detection Process
Tub and shower leaks have different causes, so the steps flex — these checkpoints keep decisions simple.
Symptom Review
We start with what you've seen — stains, smells, sounds — and check the rooms above and below the bathroom. About 15 minutes.
Fixture Testing
Each fixture gets run and dye-tested: tub spout, showerhead, drain and overflow. This isolates the leak to one component.
Moisture Mapping
Meters map moisture in surrounding walls and floor, showing how far water has traveled from the source.
Source Confirmation
We verify the exact failure point and photograph it, so you see what we see before any repair talk.
Repair Guidance
You get a clear write-up of the fix needed and can have our technicians handle it or take it to your own contractor.
Tools & methods
Tools and Methods for Bathtub Leak Detection
Compact detectors built for bathrooms, used by trained technicians to find leaks without demolition.
Dye Testing
Colored dye in drain water reveals the precise escape path through gaskets and seals.
Pin Moisture Meters
Pin probes read moisture inside drywall and subfloor without opening anything.
Thermal Camera
Infrared shows cold wet areas behind tile and under tubs that eyes can't see.
Borescope
A tiny camera looks inside wall cavities through a pinhole when we need visual proof.
Use cases
When to Use Bathtub Leak Detection
These examples show how tub and shower work adapts to the bathroom rather than forcing one standard repair.

Before: Musty Smell, No Stain
The bathroom smelled damp but looked fine. → Moisture mapping found water wicking behind the tub surround from cracked grout. Resealed before the subfloor rotted.
Before: Loose Floor Tiles
Tiles beside the tub felt spongy underfoot. → The tub drain seal had failed slowly for months. We pinpointed it in one visit and the repair stayed contained to the drain area.
Problems we solve
Problems Solved by Bathtub Leak Detection
Bathroom leaks cause some of the most expensive water damage in McLean VA homes because they hide so well. Here's what we solve.
Water traveling inside walls from the tub area.
We trace the path back to the exact fixture or joint, so the repair fixes the cause — not just the stain.
Ceiling stains on the floor below the bathroom.
Our testing confirms whether the tub, shower or drain is responsible before anyone opens the ceiling.
Musty odors with no visible leak.
Hidden moisture gets mapped and measured, catching slow leaks months before they'd show.
How do you find a bathtub leak without removing tile?
We use dye testing, moisture meters and thermal imaging to locate the source through the tile. Most bathtub leaks are diagnosed with zero demolition.
What are the signs of a bathtub leak in McLean VA?
Stains on the ceiling below, musty smells, loose tiles near the tub, peeling paint and higher water bills are the common signs.
How long does bathtub leak detection take?
Most bathroom leak inspections in McLean VA take 1–2 hours, including testing every fixture.
Can a small tub leak really cause big damage?
Yes. A slow drip behind tile can rot a subfloor in months. Early detection keeps the fix small — often just a gasket, seal or recaulk.
