RV Water Leak Test in Washington
Washington rain finds every weak seam eventually, and a leak test before you pay is the cheapest insurance you will ever buy on a rig. Eleven mobile inspectors across the state list leak testing, and each one also does pre-purchase work, so the same visit can cover water intrusion, propane, and mold concerns. I have paid for two inspections and walked from one deal over what the report showed. Here is how to use this list well.

What a leak test actually covers
A proper leak test is not a hose sprayed at the roof for ten minutes. It means a moisture meter run along interior walls, ceiling panels, slide-out floors, and the corners where water pools out of sight. Ask the inspector to document readings room by room and photograph anything damp. All eleven inspectors here list moisture checks, and all eleven also list roof work and mold assessment, which matters because a wet wall that looks fine in July can bloom by October. If the report shows elevated readings with no obvious source, that is a reason to slow down, not a reason to bargain harder. Water travels.
Certification and the written report
None of the eleven inspectors here hold the NRVIA certified tag, though all are mobile and will come to the seller or the storage lot. That is not a dealbreaker, but it means you should ask about training, insurance, and what equipment they carry before you book. Every inspector should hand you a written report with photos, not a verbal thumbs up at the curb. Get it in writing and read it before the deposit becomes nonrefundable. The one named inspector on this list, A1 RV Repair, carries a 5.0 rating from a single review alongside a 1.0 from two others, so call and ask questions rather than trusting the average of 3.7 alone. Reviews this thin tell you little.
Timing the test around your purchase
Schedule the inspection before your deposit is locked in, and never let the seller arrange the inspector. You want someone whose only customer is you. If the rig is winterized or has been sitting, ask that the test happen with systems pressurized so a leak shows up under load. What I look for in the report: interior moisture readings, roof and sealant condition, and whether the inspector pulled the access panels to check behind the shower and under the sinks. Combine the leak test with a generator run and a chassis check on a motorhome, since all eleven of these inspectors list motorhome work and propane too. A wet floor under a fridge is worth knowing about before you sign.

Questions people ask
How many leak inspectors serve Washington?
Eleven inspectors are listed for RV water leak testing across Washington, and every one of them is mobile, so they travel to the rig rather than requiring you to haul it somewhere. All eleven also list pre-purchase inspections, which makes it practical to fold a moisture check into a broader walkthrough before you commit to a purchase.
Do any Washington leak inspectors hold NRVIA certification?
None of the eleven listed here carry the NRVIA tag, so ask each inspector directly about training and experience. NRVIA has inspection levels that require coursework and testing, and a certified inspector is a reasonable preference, but plenty of capable mobile technicians work without it. What matters most is a written report with moisture readings and photos.
What should the leak report include?
Moisture meter readings by area, photos of anything damp, roof and sealant condition, and notes on slide-outs, windows, and plumbing penetrations. Ask whether they check behind access panels. A report that says only that the rig looks dry is not enough to protect your money, especially on a used unit.
When should I book the test during a purchase?
Before your deposit turns nonrefundable. Book it once you are serious about a specific rig and schedule it yourself rather than letting the seller choose the inspector. On a motorhome, allow time to also run the generator and check the chassis, since water intrusion and mechanical problems often show up together on a rig that has sat.
