This stops warm air from venting out in winter, and cold air from entering in summer. Window seals are made to last for a long time however they may become damaged or worn down over time because of extreme weather conditions or wear and wear and tear.

If your seals are damaged, moisture could get inside the glass panes, causing fog and distortion.

By regularly checking your seals, you can ensure that they're in good condition and not leaking or damaged.

There are a variety of ways to replace window seals whether you have uPVC frames or aluminium frames. For uPVC frames, wedge gaskets are the most commonly used seal. They are easy to take off and easily replaced by pulling them away from the window frame at the cut ends. The new seal is recommended to cut slightly oversize to accommodate shrinkage as time passes.

A different type of seal, called a "lip" seal, is used for aluminium frames. These can be more difficult to remove and replace, however it is possible when you follow the correct steps.

The Tools You'll Need

Double-glazed windows are a fantastic way of saving energy and ensuring a comfortable home environment. If the seals on your windows are damaged or worn out, this can compromise their airtight insulation and cause condensation, drafts, and other issues. Fortunately, these issues can be resolved by replacing the seals.

You'll also need a range of tools to complete this job. A gasket roller, for example is a great tool to push the new seals in the right place and ensure they have a solid fit. Its pointed end is also useful for getting into corners. Other handy tools include a deglazing tool and caulking gun. The Woods N4000 Deglazing Tool from GGR Glass is a practical option for this task as it lets you apply pressure evenly across the surface, minimising the risk of damage or marks.

Remove the old seal from the frame prior to installing the new seals. This can be a challenge especially if the previous seal is stuck to the frame or glass. You should take it off as soon as you notice that it is loose, or that it is no longer fitting snugly.

If the seal is not removed quickly, it could lead to a number of problems. One of the issues that can occur is the development of mildew and mould as water seeps into the space in between the windows. The condensation that forms in the space between your windows can also alter the appearance of your home and lower the efficiency of your home's energy use.

The most obvious indication that seals are in need of replacement is if you notice that the window is leaky or if you notice condensation between the windows. You should also replace the seals whenever you notice an increase in energy bills. This is because the broken seals allow heat to escape, causing your energy bills to rise.

The replacement of window seals can increase the comfort and efficiency of your home. However this is a task that should be left to experts who can provide the highest quality results.

Cleaning the Window Frame

A failed double glazing seal could be a major cause of damage to your home and windows. Moisture from a broken seal could cause condensation between the window panes, and can even cause damage to the frame. It is important to address the issue promptly to avoid mould and damp which could be hazardous for your pets and family members.

Failed seals are often caused by age, natural wear and wear, or external influences like weather or direct sunlight. Double-glazing units may also be damaged or installed incorrectly. Regardless of the cause it's crucial to determine the best solution as quickly as possible to avoid costly repairs and replacements.

You can replace the seals on the double-glazed window in a number of ways but the most efficient method is to scrape off the caulk or sealant that has been applied to the frame with a blade. Make sure the area is free from any obstructions and clean prior to beginning. Once you've removed the old sealant it's a good idea wipe down the entire frame with a damp cloth and then apply a water-proof, mould resistant silicone sealant on the area where you plan to place the new seal.

The best rubber seal is called "bubble gasket". It's a circular, oval or rounded seal with an arrowhead on one end to help it stay in the grooves of your uPVC frame. Bubble seals are a favorite with homeowners, as they're simple to install and efficient in keeping cold air out and warm air in during the winter.

In addition to the bubble seals, you'll likely have a spacer bar in your double-glazed window. It is used to create an opening between two glass panes to provide thermal insulation. The spacer bar is constructed with a desiccant that absorbs moisture, thus preventing it from leaking between the two panes. The spacer bar, just like the rest of your double-glazed windows, is susceptible to failure of sealants. This is especially true when it expands or contracts with temperature changes.

How to apply the New Seal

Apply the new sealant once the area is clean and ready for resealing. Apply tiny beads of sealant onto the frame using the caulking tool. It's important to fill all crevices and gaps to ensure an airtight seal. Use a silicone caulk which will be able to stop mould, water and other elements that could harm the window frame as well as the walls surrounding it. Let the sealant dry and cure as per the instructions of the manufacturer prior to returning the window.

One of the major advantages of double glazing is its ability to cut down on energy bills by blocking heat loss through the window. The window seals may be damaged and result in a decrease in the efficiency of the seals which will increase the cost of heating your home. In addition, broken seals could cause condensation between two glass panes, which could lead to toxic mould growth.

Check the condition of your uPVC double window seals on a regular basis to determine if they need to be replaced. This will stop a myriad of common problems such as condensation, draughts and leaks of water. In most cases, replacing the window seals is enough to resolve these issues.

In certain cases it is possible that resealing will not be sufficient to resolve the issue, and a full replacement of the double glazing unit may be required. This is especially true if the insulating gas between the two glass panes is argon or Krypton, that isn't able to be replaced by applying new sealant.


In these cases, a complete replacement of the double glazing unit is generally an affordable and effective option than ongoing maintenance work for the windows. Professional window resealing might not be as effective at solving these kinds of problems as a complete replacement of the glazed units.
