The walls of your camper have been damaged by rain, and you don’t know how to fix it. Yes? If so, we’ve got all the information you’ll need to get to the bottom of it in this article.

What Is A Camper Wall?

For the most part, campers have three walls: a front and back outer skin, a middle layer of insulation, and an inside wall. For the outside of the camper, fiberglass, composites, or aluminum are frequently used.

The most well-known name in aluminum-clad travel trailers is Airstream. Most other campers have fiberglass or composite exterior walls.

After that, a layer of insulation is placed between the interior and outside walls of your camper. RVs are often insulated with a combination of fiberglass, spray foam, or rigid foam.

Fiberglass is the most common type of insulation found in campers. In addition, “R-Values” can be used to measure the camper’s insulation.

What Causes Water Damage in an RV?

Several factors contribute to water damage. It’s possible for water to get into your RV in a number of ways, but here are the most common:

  • The internal plumbing in your kitchen or bathroom may be leaking water if you don’t perform regular maintenance on it.
  • We had this happen to us, which is why we had to remove our toilet and install a Thetford Portable Toilet!
  • Water damage might occur if your RV is not properly stored.
  • Warped wood can be caused by excessive moisture and high humidity.
  • Many different aspects of your RV might be damaged by leaving it parked in a flooded location.

Owners of RVs should be able to tell if their vehicle has been damaged by water and have the tools to make basic repairs. Consistent maintenance should help you avoid more serious issues that might necessitate the services of a professional.

How to Check for Water Damage in Your RV

Even if you keep your RV in storage or are full-timing, you should check for symptoms of water damage and see if anything needs to be repaired or replaced before you buy a secondhand RV. You’ll need to pay special attention to the following “trouble areas”:

  • Verify the integrity of each and every one of the seals. To find any soft or moist places, run your fingers across the seals of every door and window. Cracks and flaking can occur in older sealants. Re-sealing these locations is necessary if you see any of these warning indications.
  • Open all of the drawers and cabinets. It is possible to smell water damage even if you cannot see mold development, which is a sure sign of water damage.
  • The wood cabinets and the ceiling should be checked for any discolouration. If water damage is evident, the paint around windows and doors will turn a different color.
  • Verify the exterior of the building. This could be a hint of a leak if you notice any warped areas or bubbles in the paint.
  • Check the underside of the carpets to see if they are glued down. A water leak is evident if it’s cold or damp. Check the glued carpets for any cold or moist patches with your fingers.
  • Water damage can cause metal parts to corrode and molded parts to come loose.
  • Look for rusty spots on windows and doors.
  • Test for weak or soft points on the RV’s roof and ceiling with a stick. (*Leaks in the roof are a severe issue. Even a minor leak might lead to the entire roof needing to be replaced if left ignored. An RV roof replacement can run into the hundreds of dollars, so don’t skimp here.)

RV Water Damage Repair Costs

The cost of fixing water damage in an RV varies greatly depending on the severity of the damage and whether or not the repairs can be done by the owner. When dealing with water damage, you may encounter the following scenarios:

  • Just a few applications of sealant are all that is needed to fix a minor window leak. This modification should cost no more than $20. Keeping water leaks at bay, we use Gorilla Clear caulking on our windows. Investing $20 now will save you a lot of money in the long run.
  • Dehumidifiers are an excellent purchase if you’ve been parking your RV in an area with flooding or high humidity. They range in price from $30 to more than $100 and will keep your RV dry.
  • In rare circumstances, a malfunctioning refrigerator may be to blame. You can typically fix a fridge problem on a budget if you’re handy with tools and have the know-how, but RV fridges are notoriously expensive to replace if you’re not: The price ranges from $200 to more than $1,000.
  • If the problem is with your toilet, a new one is an inexpensive and simple solution. The typical price is about $130, but it can go as high as $1,000. With a few common hand tools, most RVers can simply swap out the more typical $130 toilets. If you can address this problem yourself, you’ll save a lot of money in the long run, just like with everything else in an RV.
  • Depending on the type of RV floor you have, and whether or not you can fix it yourself, repair costs can vary greatly. Because of its durability and low cost, laminate flooring is extremely popular. Laminate can be purchased for as little as $15 per sheet! Vinyl flooring, on the other hand, is inexpensive and self-adhesive, making it a breeze to install. Vinyl flooring can be purchased for as little as $12 per square foot.

Look Out For These Signs Of RV Water Damage

What Are Different Types Of RV Interior Wall Materials?

The internal walls of your RV can be constructed from a variety of materials, each with its own set of advantages and disadvantages.

1. Compound or composite plywood

Several thin wood sheets are pressed together to form plywood. Interior walls made of plywood are increasingly typical in more expensive campers. Remove all wallpaper, veneer, or paint from plywood inside walls before making any color changes.

Here are the advantages and disadvantages of the composite plywood:


Plywood has a high degree of tensile strength. It’s quite difficult to shatter or bend, and it’s highly rare that you’ll accidently punch a hole in it. The plywood walls of a secondhand RV can be readily painted or covered with wallpaper of your choice if you don’t like the color.


The plywood used in RVs is susceptible to water damage, and this is a common issue. Plywood walls become extremely brittle very rapidly if there is a leak in the roof or another hole in the wall that allows water to fall.

There is a reasonable chance that mold will grow in your RV’s plywood walls if you have a significant water leak inside. By rapidly detecting and repairing water leaks, you can avoid this issue.

2. MDF (Medium Density Fiberboard)

RV interior walls are often made of MDF. Wood veneer is layered between two sheets of sawdust, which has been cemented together.

The following are some of the advantages and disadvantages of MDF:


For a low price, MDF can be used to replace the inner walls of your RV. Keeping the weight of your RV down is essential if you’re traveling by automobile.

An easy-to-cut MDF form for RV interior walls means that it is a flexible material. Additionally, it’s adaptable in that it may be painted over, decorated with wallpaper, and hung with family photos.


MDF’s lifespan is shorter than that of other RV wall materials. Because it’s built of glued sawdust, the entire wall is vulnerable to deterioration over time.

3. Vinyl

In recent years, vinyl has come a long way and is now a cost-effective option for RV interior wall coverings. Unlike other plastics, vinyl has the ability to tolerate a lot of abuse. For RV interior walls, it’s a popular choice because it’s lightweight and easy to put up.


It’s a bargain. A large sheet of vinyl for the interior walls of your RV can be purchased at a reasonable price. You’ve already saved money if your RV’s inside walls are composed of vinyl!


Vinyl is the least long-lasting material for RV interior walls. After around two years, vinyl starts to show symptoms of wear. However, because it is so cheap, you can usually replace it multiple times before paying what other RV interior wall materials would cost.
