The Fiberglass On The Side Of My RV Is Swollen, What Do I Do Now?

by Rolf
(Phillpsburg NJ)

Below window the fiber glass side is swollen. Will it go down when insides dry this spring? It will cost a fortune I don't have till next year.

ANSWER: Greetings Rolf thanks for submitting your question on our Ask An RV Question Page.

I am afraid that I am not the bearer of good news. My advice is not to wait to get this repaired, it should be repaired immediately.

Based on your description it sounds like the window on that side of the RV has developed a leak and moisture has gotten into the walls of the RV causing the Fiberglass to delaminate.

The window needs to be removed and resealed, but that is the least of your worries, resealing an RV window is not that complicated, but the fact that the side of the RV is warped means that the window may not reseal properly.


If you choose to wait to do the repairs, you are going to end up spending more money to get it repaired at a later time. The fact that the fiberglass is detaching from the main structure of the RV indicates that the structural integrity of your RV has already been compromised.

Each time more moisture gets in the wall of your RV it will cause further damage. You should also be concerned that the moisture in the wall will promote the growth of potentially harmful Molds and Mildews.

I cannot tell you whether the swelling on the side of your RV will go down or not, but you should not ignore the fact that holding off on the repairs will end up costing you a lot more money in the long run than it will in getting it repaired now.

I am very sorry that you are going through this.

swollen siding

I'm having the same problem I've done the repairs of fixing the leak that caused the problem and considering using rubber washerd screws to suck the siding back in dont know if this is a great idea but high priced repairs are just out of the question at this time I think as long as I'm screwing into the studs and not just the sheeting it might work.
