We love traveling in our RV, but like any other vehicle, it needs regular maintenance to stay in good shape. Many often forget the RV weather stripping – something that’s especially important in colder climates.

Here are a few tips on keeping your weather stripping in good condition and some of our recommended products.

What Is RV Weather Stripping? 

RV weather stripping is a sealant used to fill in gaps and seal off areas around doors and windows. It typically has a flexible material like rubber, vinyl, or foam, and you can apply it by hand.

Maintaining your RV’s weather stripping is an important part of your RV’s upkeep, as it helps to keep out drafts and reduce noise.

It can also help prevent water damage by keeping out moisture and preventing leaks.

When choosing weather stripping, select a product specifically designed for RVs. Standard seals may not withstand the wear and tear of RV travel.

How Does RV Weather Stripping Work?

RV weather stripping helps create a barrier between the inside of the RV and the outside elements. It seals areas around openings like doors and windows.

The stripping helps keep out dirt, dust, and pests while also helping to regulate temperature and moisture levels. It also helps to reduce noise and prevent vibrations.

How Do You Replace Weather Stripping on a Camper? 

RV weather stripping is essential for keeping your RV insulated and draft-free. Over time, the weather stripping on your RV will become worn and damaged, making it necessary to replace it.

The good news is that replacing RV weather stripping is a relatively easy and inexpensive DIY project.

You’ll find different types of weather stripping. Some you apply differently than others, but the basics for installing new weather stripping boil down to a couple of essential steps. Here’s what you’ll need to do:

Remove Old Weather Stripping

Start by removing the old weather stripping. Use a putty knife or screwdriver to pry off any old seals that don’t come off easily. Be careful not to damage the surface of the RV.

Clean The Area

Once you have removed the old weather stripping, clean the surface where the new stripping will go.

Make sure you don’t leave dirt, debris, or residue behind.

You can use soap and water, mineral spirits, or rubbing alcohol. However, be sure to double-check that whatever cleaning agent you choose is safe to use on your RV.

Cut New Weather Stripping

Next, unroll the new weather stripping and cut it to size. You can eyeball this by holding the weather stripping to where it is going to be placed on your RV.

Or if you’d like an exact measurement, break out your measuring tape.

Apply Weather Stripping

Finally, apply the new weather stripping. How you do this depends upon the type of stripping.

Some slip into place with a self-gripping technology, and other types have a self-adhesive application. However, some require a separate adhesive, which we don’t recommend. 

The way you apply the weather stripping depends on its location on the RV.

For instance, the seals for door frames frequently have a self-adhesive, while windows and slide-outs use self-gripping technology.

If you know what type of weather stripping you need for your RV, the next step is to measure the area you need to apply it. For instance, measure the top, bottom, and each side of the door frame. Then add those measurements for the length of weather stripping you need.

Is Foam or Rubber Weather Stripping Better?

Most weather stripping comes from one of two different materials: foam or rubber. Each has its advantages and disadvantages. 

Foam is affordable and easy to install. It also does a good job of sealing out drafts.

However, foam weather stripping can compress over time, allowing gaps to form. It can also sustain more damage from UV rays and extreme temperatures. 

Rubber stripping costs more, but it is also more durable. It can withstand UV rays and extreme temperatures without breaking down.

And it will maintain its shape over time, particularly if you also use a rubber seal conditioner. Rubber creates a tighter seal than foam and will last longer.

If you want a more affordable option, go with foam. But if you want a tighter seal that will last longer, choose rubber.
