Introduction
Are your windows drafty? Do they stick or have visible gaps between the window and the frame? If so, it might be time to replace your window gaskets.
In this guide, we will cover what you should know about window seals so that you can make an informed decision about whether or not they need to be replaced.
What are Window Gaskets?
Window gaskets are seals that go around the window panes to prevent air and water leakage. Over time, they can degrade and need to be replaced.
The most commonly found window gaskets are:
- Bubble gaskets
- E-gaskets
- Wedge gaskets
- Flipper gaskets
Types of Window Seals
Bubble Gaskets
A Bubble gasket is a curved shape seal that is made up of small, round bubbles. These bubbles create a seal that is effective in keeping out drafts and air leaks. Bubble gasket seals are often used in situations where a traditional flat gasket would not work as well.
E Gaskets
E gaskets are a type of window seal that helps to prevent drafts and leaks. They are usually made from thin pieces of metal or other materials and can be found in a wide variety of colours and styles to match your window’s design.
Wedge Gaskets
A wedge gasket is fitted between a double-glazed unit and the uPVC frame to hold the glass securely in place. They are made up of a thin piece of metal that is wedged between two surfaces. A wedge gasket provides a tight seal that prevents air and water from leaking through.
Flipper Gaskets
A flipper gasket is a compression seal that is used when the latching isn’t able to get a good compression seal on its own. When a window is closed, the flipper gasket will compress and fill any gaps between the frame and sash. This creates a seal that prevents air and water from entering the home.
Brush Type Gaskets
Brush-type gaskets are draught-proofing seals which are used in a variety of applications such as draught sealing around patio doors and sliding windows. They are made from a range of materials including PVC, nylon and polypropylene and can be customised to fit the specific application.
Window Gasket Materials
We stock a variety of window gasket materials, each with its advantages and disadvantages.
The three main materials used for window gaskets and seals are:
- Silicone is a more durable option that can be used for both wood and metal frame windows.
- Neoprene is the most durable option and is typically used for metal frame windows
- Felt is the most common type of gasket and is typically used for wood frame windows.
How to Tell if Your Window Gaskets Need to Be Replaced
There are a few tell-tale signs that your window gasket needs to be replaced:
- Drafty windows
- Window glass that has condensation on them
- Windows that are leaking water
- Windows that stick, making them difficult to open or close
- Visible gaps between the window and the window frame
- Windows that have a build-up of dirt or dust on the gasket
If you notice any of these issues, it might be time to replace your window gasket. Window seals play an important role in keeping your home warm in the winter and cool in the summer, so it’s important to make sure they are in good condition
The Benefits of Replacing Your Window Gaskets
Increased energy efficiency
By replacing your window gasket, you can help to block drafts and reduce air leakage. As a result, your home will be better insulated and help to lower heating bills.
Reduced noise pollution
Your windows are one of the main sources of exterior noise pollution in your home. By replacing your window gasket, you can significantly reduce the amount of exterior noise that enters your home.
Prevents drafts
One of the best ways to keep your home warm during cold weather is to stop draughts by replacing window seals. However, these gaskets can deteriorate over time and drafts can occur when cold air leaks through gaps, making your home less comfortable.
Absorbs sound waves
Gaskets are designed to create an airtight seal around your windows, and this helps to absorb sound waves before they enter your home. As a result, you’ll enjoy a quieter, more peaceful environment.
Conclusion
Window gaskets are an important part of any window, serving as seals that prevent air and water leakage. Over time, they can degrade and need to be replaced. In this guide, we covered what you should know about window gaskets so that you can make an informed decision about whether or not they need to be replaced in your home.
A new window gasket can provide many benefits, such as increased energy efficiency and reduced noise pollution.

Common Questions
How Do I Choose a Window Seal?
Ultimately, the best type of window gasket for your application will depend on the type of window frame, your budget and your installation needs.
HOW MUCH DOES IT COST TO REPLACE WINDOW SEALS?
The price to reseal windows will vary because windows come in a wide range of forms and sizes. The total cost for a standard window seal replacement including labour is likely to be between £25 – £80.
HOW LONG DO WINDOW SEALS LAST?
When it comes to window seals, there are a few factors that will affect how long they last. For instance, the material of the sealant itself will make a difference. Cheaper sealants may only last a few years, whereas more expensive ones could last a decade or more.
What causes window seal failure?
There are several reasons why a window seal may fail. One possibility is that the sealant has become old and cracked, allowing air and moisture to leak through. Another possibility is that the window was not installed properly, leaving gaps around the edges where air can enter. Finally, if the window is located in a high-traffic area, the constant vibration could cause the seals to loosen over time.
