MOBILE LEAK DETECTION · WASHINGTON
Find the Leak Before It Finds the Floor
Thermal imaging and moisture readings that map where water is getting into your RV and how far it has spread, so the repair targets the actual entry point instead of resealing the whole roof and hoping.

Why RV leaks are hard to find
Water rarely shows up where it gets in. It enters at a roof vent, an AC gasket, a clearance light or a window frame, then runs along the framing and insulation and shows up as a stain or a soft spot feet away. By the time you can see it, it’s often been leaking for months. In western Washington, with a wet season that runs most of the year, that’s the most expensive problem we see.
Thermal imaging shows surface temperature differences. Wet insulation and damp panels read cooler than the dry wall around them, so the outline of a wet area shows up on the camera without cutting anything open. We confirm what the camera shows with moisture meter readings, then trace it back to where the water is getting in.
What a leak inspection covers
- Roof: seams, vents, skylights, AC units, antenna and solar mounts, and every cable entry.
- Walls and corners: front and rear caps, corner moldings, clearance and marker lights, ladder mounts.
- Windows and doors: frames, butyl tape, entry door and baggage doors.
- Slide-outs: wipers, seals, the slide roof and the corners where slides meet the body.
- Interior: ceilings, cabinet backs, wall panels and floors near every opening, with moisture readings at suspect spots.
- Plumbing: slow leaks at fittings, the water heater and under-sink lines that look a lot like a roof leak from inside.
You get a written summary with thermal and regular photos of each suspect area, the moisture readings, the likely entry points, and a repair quote. Resealing and repairs are quoted separately. See roof and seals.
What thermal imaging can and can’t do
Thermal imaging is fast and doesn’t damage anything, but it isn’t X-ray vision. It reads the surface, and it works best when there’s a temperature difference between inside and outside and the rig has seen recent rain. A completely dried-out old leak may not show at all. That’s why we always pair it with moisture readings and a hands-on check of the sealant and the floor.
It also doesn’t tell you how far rot has gone inside a wall. If the readings show a large wet area, we’ll tell you plainly and quote the repair options, including when a repair is worth doing and when it isn’t.
Buying a used RV? Scan it first.
Water damage is the most common hidden problem in used RVs, and it’s what turns a good deal into a parts trailer. A leak inspection is part of our pre-purchase inspection, done wherever the rig is parked, before you hand over money.
Pricing
A leak inspection starts with our $175 on-site diagnostic. Large rigs or full-body scans that take longer are billed at $150/hr, and we tell you up front if we expect that. $75 trip fee within 50 miles, then $2.00/mile both ways. Resealing and repairs are quoted separately after the inspection. See the pricing page.
Leak detection FAQ
When is the best time to scan?
Within a day or two after rain, on a cool morning or evening when inside and outside temperatures differ. In western Washington, that’s most of the year.
Do you have to cut anything open?
Not for the inspection. Thermal imaging and pin or pinless moisture readings don’t damage the rig. Opening a wall is only part of a repair, and we quote it first.
Can you do it at a storage lot?
Yes, if the facility allows outside technicians. See storage lot service.
Where do you do leak inspections?
Throughout Washington: Seattle and Puget Sound, Kitsap, the Olympic Peninsula, the coast and route days east of the Cascades. See all of Washington.
