Motorhome & Caravan Window Seals
Over time the seals around the windows shrink, perish and become less effective so need to be replaced. Replacing your seals is essential for preventing damage to your vehicle. Our caravan and motorhome window rubbers are specially designed for caravans and motorhomes with either opening or fixed windows. These seals are available in a range of sizes and fit the majority of caravan and motorhome makes and models. Our window seals are manufactured from a high quality sponge and solid EPDM. When replacing your opening window rubbers we recommend replacing the cover insert strip using our cover strip fitting tool and silicone spray (purchased separately).

Overview explaining importance of window seals for caravans and motorhomes
The most important role that motorhome and caravan window seals play is for protection purposes. Over time, these seals around the windows will naturally shrink and deteriorate, affecting their performance.
If the caravan window seals (or any other seals) aren’t performing their job effectively, you might see water seeping into the interior of the vehicle following or during heavy rainfall. This can have the unwanted result of water damage and even encourage mould to grow in an area where you should feel comfortable.
Similarly, if you’re fond of seaside trips away in your caravan or motorhome, then you may want to consider the affect that salty sea water can have on both the appearance and performance of your vehicle. Not only can regular exposure to this salty water damage the bodywork, but it can also lead to the gradual deterioration of the various seals around the vehicle.
It’s also worth bearing in mind that if your caravan has clocked up a lot of miles over the years or you’ve purchased a second-hand caravan, then the seals could already be in a worn condition. Alternately, if you’ve had new replacement caravan window seals fitted recently, you must ensure they’ve been properly installed.
Both poor installation as well as the correct installation of the wrong type of caravan window seal can lead to water leaking into the vehicle and subsequent damage.
If you see any significant signs of damage or indications that the seals aren’t working properly such as water coming through the seal or the formation of mould, fungus, or moisture, you should consider replacing them.
Replacing caravan and motorhome window seals
Regardless of whether your caravan window seals have naturally perished over time and become less effective, or they’ve suffered substantial damage from a break-in attempt, the prompt and professional replacement of these seals is essential for preventing any further damage to your vehicle.
To ensure you pick the right replacement for your window caravan seal for your vehicle, you’ll need to know four key pieces of information – the size of the window, the diameter of the existing seal bulb, the thickness of the vehicle’s walls, and whether the window is fixed or opening.

Different types of window seal for caravans and motorhomes
There are just two key types of caravan window seals – those designed for fixed windows and seals designed for opening windows.
However, each of these primary types of caravan window seals are also available in a wide range of widths as well as sealing bulb shapes and sizes to ensure you can find one that fits both the make and model of your caravan or motorhome.
Here at Seals Direct, our range of caravan and motorhome window seals includes both the seals themselves as well as the insert cover strips in a selection of width sizes and even colours. Why not explore our online selection to discover the full range of window seals for caravans and motorhomes?
All our motorhome and caravan window seals are manufactured from a high-quality sponge and an incredibly durable synthetic rubber roofing commonly referred to as EPDM (ethylene propylene diene terpolymer).
This type of special caravan window rubber provides excellent weather resistance and good heat ageing properties among many other benefits. Some of our motorhome and caravan window seals also come with pre-applied butyl mastic on the inside of the seal to form a flexible seal with good weather resistance.
Choosing the right window seal for your caravan or motorhome
To ensure you choose the right caravan window seal replacement that will deliver a tight fit and optimum weatherproofing, you’ll need to know the size of the relevant window, the thickness of the walls, and the diameter of the existing seal bulb.
Firstly, you should measure the thickness of the caravan or motorhome walls as caravan and motorhome window seals are sold in various widths based on the width of the vehicle’s walls. Here at Seals Direct, we stock caravan window seals to fit wall thicknesses from just 23mm up to 40mm.
To determine the correct panel thickness, simply remove the existing seal and measure the thickness of the wall, which should fall between 25mm and 40mm. Then, examine the existing seal and determine the shape (it will either have a fun or a double bubble) and diameter of the sealing bulb – this should be between 10mm and 14mm.
We offer caravan window seals with sealing bulbs in varying shapes and diameters – these bulbs can be particularly useful for ensuring a long-term seal between multiple surfaces that helps to prevent weather, corrosion, heat loss, and water-related issues.
You can then measure around the edges of the window to identify how long the seal should be. Sold per metre, you should round up to the closest metre to ensure you have enough to go around the entire window with some material to spare.

Installation guide for window seals
After you’ve managed to successfully remove the existing caravan window rubber seal, you’ll need to thoroughly clean the area and leave it to dry. Then, you can move onto fitting the new caravan window seal.
While every product will come with specific installation instructions from the manufacturer, generally, you should start by placing the caravan window rubber seal around the window opening. It should be firmly pressed into the corners before trimming the seal to the required length and leaving a small amount of additional material to create a joint and allowing you to ensure the ends can be fitted tightly together. Use staples to secure to the caravan window seal and simply cover with insert strip.
For a safe and neat join and finish to this installation, cover strip (available at Seals Direct in various colours) can be easily applied into the motorhome or caravan window rubber. You can do this either using your fingers or with a helping hand from our convenient our cover strip fitting tool and silicone spray.
Combined, the silicone spray allows the cover strip fitting tool to smoothly slide around the channel, making the process of installing the cover strip much easier and quicker. Simply lubricate the inside of the window channel using the spray, then insert the tool ensuring the two legs at the back of the tool are within the channel lips.
The cover strip should then be inserted through the middle of the tool and pushed into the channel, under the lips. Slowly move the tool forward to apply the cover strip until you’ve covered the entire caravan window seal. Simply finish the installation by overlapping the end of the strip on top of the starting point.

Maintaining and caring for window seals
Once you’ve installed new motorhome or caravan window seals, the last thing you need is for the seals to start deteriorating. Cue, the importance of properly maintaining and caring for your caravan window seals.
Instead of automatically opting for the most powerful automotive cleaning solutions to wash away dirt and grime, using warm soapy water is often sufficient and won’t carry the risk of causing your new seals to peel. Frequent and thorough cleaning with a soft cloth and warm soapy water is therefore the safest option to keeping your caravan window seals in good condition.

Regular
cleaning is particularly crucial if you take your caravan or motorhome on many
trips to the seaside. Constant exposure to the salty water could damage these
seals as well as the bodywork, so it’s important to wash the vehicle down
following any seaside adventures.
