Why Sealants Fail
RV seals can fail for several reasons: age, improper repair due to poor preparation, choice of sealant, and poor application.
Regularly scheduled RV maintenance of the exterior seals and sealants are critical to finding sealant failure early to prevent costly water damage.
On-Site Testing Maintenance
RV ProSeal provides diagnostic water penetration testing (leak testing) for water tightness, combined with a 2-hour physical examination.
It’s not just the roof!
Anywhere a hole was cut into all four sidewalls or roofs, waterproofing seals and sealants are used for a water-tight seal.
Sidewall trims, corner joint trims, window & door frames are other vital areas that can leak. The primary seals behind the trim, if the factory-installed one, are not visible for inspection.
Our testing equipment is required to locate gaps and voids in the seals behind windows and trim to find hidden leaks. When hidden leaks go undetected, damp smells, rot & mold start, glues separate, delamination starts, and unhealthy living conditions develop.
Living in high-moisture and damp environments puts the RV and the family’s health, comfort, and performance at risk.
Use of New Test Equipment
New technology enables us.
Just like James Bond had “Q” to enable him in difficult situations, we too have our own gadget master named “DP”.
We brought and utilize new testing equipment, experience and repair products to the RV industry.
RV Slide-outs
Before the invention of slide-outs/pop-outs, pressure leak testing was done to find leaks. However, slide-outs presented a new problem due to the amount of air leakage they can have.
We solved the slide-out problem with testing. Thanks to DP, we have advanced equipment to test the slide-outs internal and external seals.

Frequently Asked Questions
Why choose a RV leak testing / inspection company vs any mobile RV tech?
1. Specialization vs generalization
RV inspection/leak detection is not the same domain as appliance repair or awning installation. Specialists accumulate failure modes; generalists accumulate anecdotes.
2. Diagnostic equipment
Pressure testing, thermal imaging, moisture mapping, airflow tracing — these are force multipliers. No tools = opinions. Tools = evidence.
3. Information density of output
A useful inspection creates a decision advantage (buy, walk, repair, renegotiate). If an inspector’s output could be summarized as “looks good,” run.
4. Time horizon awareness
Good inspectors think in timelines:
- immediate defects
- near-term failures
- deferred risks
Most buyers only think in terms of purchase price, layout, and cosmetic condition.
Why do all RVs leak sooner or later?
Rain leaks in RVs can occur due to improper caulking, damaged seals, gaps, cracks and adhesion faliure on sidewalls and roof. Inspect these areas regularly to prevent leaks, reseal as needed, and ensure proper maintenance. Water intrusion can lead to structural damage and mold growth if not addressed promptly.
How do I identify a RV rain leak?
Detect RV rain leaks by checking for damp carpets, musty odors, staining or ripples on walls or ceiling. Unfortunately, at this point water damage has already set in. RV owners can start by Inspecting seals and sealants, windows, and the weather stripping for wear or damage. Clear clogged gutter rails and replace faulty weather stripping. However, without the proper testing equipment and know-how finding the source of the leak will be a guessing game.
Can RV leaks be fixed at home?
Caulking looks alot easier than it really is to get an professional finish. Most RV techs fail in this area too. First, one must properly identify the source(s), properly prep the area, and apply appropriate sealants or adhesives. Promptly addressing leaks correctly helps prevent further damage and ensures the longevity of your RV.
Other than my roof, where am I most vulnerable for leaks?
Outside walls have many holes for lights, accessories, screw trims, windows and doors. Fiberglass walls and leaks equal delamination ripples and bubbles. A very expensive repair to solve and 98% of buyers will run away.
