Pennsylvania RV owners keep your RV properly sealed.

On your RV regardless if you own a tow-able unit or a motorized one, sealants perform a very important function by keeping water from getting into places it should not get into. When manufacturers build RVs,  they incorporate many different types of sealants, including butyl/putty, black butyl-encapsulated foam, silicone (clear and colored), roof sealant and foam to the places that need it. However, over time, these sealants may become damaged by ultraviolet exposure, air pollution, freezing temperatures and exposure to other elements. That is why it is important to inspect, maintain or reseal your RV. Failure to properly maintain or re-seal your RV may result in serious water damage to the roof and other parts of the RV. For most RV owners, failure to maintain proper seals disqualifies your unit from coverage under the most Limited Warranties.

To ensure that you are properly maintaining and re-sealing your unit, here are a few things you or your dealer’s service team should do:

Visually inspect all seals and sealants, a minimum of every six months. Make sure to check the roof and all four sides of the RV including all moldings, doors, vents and exterior attachments. A quick walk around the RV before leaving may help prevent potential problems during trips and vacations. A little preventative maintenance goes a long way, especially when compared to the high cost of repairs. Another great time to have your RV looked over is during your annual state vehicle inspection(if your state requires your RV to be annually inspected).

  1. Have the sealant replaced if you notice any cracks, peeling, voids, gaps, breaks, looseness or any sign of physical deterioration. Re-seal at least one time each year as preventative maintenance.
  2. Always use the same type of sealant that was removed. Your dealer service or parts manager can help you obtain the correct sealant(s).

If you do find water inside of your RV, be sure to immediately have your local central Pennsylvania dealer check for the source of the leak. If the leak is not fixed, it may result in serious damage to your RV, which may not be warrant-able.

A small amount of time now, can save you a large expensive headache later!

Leaky RV Window? Here is the fix…

Much like the window and door frames on your house, the window frames of an RV are sealed with caulk. Over time, caulk eventually decays, causing a leak. With their thinner walls, these leaks are much more apparent on an RV. They can also be much more destructive to the plywood construction used in many RV models. You should act to replace the caulking on the window as soon as you become aware that the window is leaking.

Step 1

Inspect the caulking around the perimeter of the RV window frame. Wherever the caulk is cracked, crumbling or a gap has opened between the bead of caulk and the window frame is a potential leak.

Step 2

Remove the damaged caulk from the RV window frame. Cut and pry up the bead of caulk with a disposable razor blade or a putty knife, and pull as much of the bead out by hand as possible. Remove the remaining caulk by scraping it out with a razor.

Step 3

Clean the RV window frame seams. If there are any major bits of old, damaged caulk still in the seam, break it down and remove it with an acetone-based solvent. Then wash out the seam with car wash detergent, water and an old rag. Allow the clean-up to dry before proceeding.

Step 4

Caulk the RV window frame with RV sealant. Apply steady pressure to the caulking gun’s trigger as you slowly draw a constant bead of caulk around the window frame, filling up the seam. Gently remove any excess caulk with the razor blade.

Things You’ll Need:

  • Disposable razor blades
  • Putty knife
  • Acetone-based solvent (if possible)
  • Car wash detergent
