Professional Exterior Leak Prevention

Most owners are unaware they have a leak before mold, and dry rot fungi start to grow. New or old, all RV types have the same maintenance schedule for seals & sealants required each year.

What is testing maintenance? 

RV ProSeal provides diagnostic leak testing combined with a physical examination. This is the  best practice in leak prevention of exterior seal & sealant maintenance.

It's not just the roof! 

Sidewall trim, corner joint trims, and window & door frames are other vital areas vulnerable to leaks — however, the primary seals behind the trim, are not visible for inspection... Special testing equipment is required. When hidden leaks go unnoticed, heating and cooling efficiencies drop, rot & fungus starts, mold grows, and smells can start.

Don't put your family's health, comfort or performance at risk.  We can come to you. Thinking of booking in 2020? 

What We Test

Where RV leaks can occur

Multipoint Inspection

An RV ProSeal Testing can inspect over 58 different areas prone to leaks. We go beyond checking just the roof and windows.

Types of Failures

Weather seals can fail for several reasons; age, improper preparation, choice of sealant and poor application are the top reasons for failure. Therefore, regularly scheduled RV maintenance of the exterior is critical to find sealant failure early.

New technology enables us. 

We are uniquely able to provide exterior leak inspection and repair services. We have introduced new testing equipment and repair products to the industry.  

RV Slideouts

Before the invention of slideouts which allow for more living space, pressure testing worked well to find leaks.    Slideouts presented a new problem due to the amount of air leakage they can have. 

We solved this problem.

Are you a new RV owner?

Why Test Your New RV Camper for Leaks?

Did you know, there are as many as 58 different external areas around your RV that require a watertight seal?  

Despite your RV dealer's best efforts to deliver you a leak-free trailer, exterior seals and sealants have failed much earlier then new RV owners expect. In as little as one road trip or 3 months from purchase, the application of sealants in various areas can fail without immediate evidence inside the RV. Unfortunately, RV's can come with various deficiencies having you return to the dealer with long wait times for warranty work. However, in most cases, exterior leaks and the damage it can cause are not items covered after 30 days from purchase. Read your owner's manual section Exterior Maintenance to learn more.  

Exterior leaks usually remain hidden for a long time causing expensive damage before it's evidentent from the inside.  Protect your health and your wallet from failing seals with Sealant Integrity Testing as part of your regular maintenance program.


Protect you

Hidden Exterior Sealants Can Leave Owners Vulnerable

RV Campgounds

RV maintenance items include maintaining exterior weatherproofing seams, sealants, and seals to prevent leaks. Water damage due to exterior water seepage or improper maintenance leaves RV owners without warranty or insurance coverage. Manufacturers and RV dealers state that owners are responsible for inspecting and monitoring all external weatherproofing of the roof and sidewall sealants multiple times per year, especially after each road trip. 

Despite RV owners' best efforts to reseal their RV themselves, it results in additional leaks due to improper repairs. They are using incompatible choices of sealants and inadequate area preparation affecting proper sealant adhesion.  For peace of mind, invite us to leak test your repair as the final step to complete the process. Owners pay a lot of money for an RV and deserve to be served with the best leak prevention, RV maintenance, and protection available.

Wind, Rain, Road and Joint Strain


Poor weather, road conditions and off-road access add significant amounts of mechanical strain on the joints, seams, and sealants protecting you from leaks. Wind pressures can drive water in through small gaps of the seals with a pumping-like action. 

When hidden or visible sealants fail to perform but seem in good shape, it leaves owners at a disadvantage to find leaks in time. 

Water Damage from Seepage

Result of poor caulking

RV'ers live a life in the outdoors. Nothing will keep owners up at night more than finding water where it shouldn't be. The real nightmare is how long did it take for the leak show itself? 

Does your RV leak but can't find the source? 

RV ProSeal testing can help you locate where the intrusion started more effectively, safely, and quickly, without damage or deconstruction.
