Rubber seals play a crucial role in maintaining the efficiency and longevity of windows. Over time, these seals can deteriorate, leading to drafts, air leaks, and even water damage. In this comprehensive guide, we’ll explore whether it’s possible to replace rubber seals on windows and provide step-by-step instructions for doing so.
Understanding Window Seals
Window seals are typically made of rubber or other flexible materials that create a tight barrier between the window frame and the glass. They help prevent air and water from entering the home while also improving energy efficiency. There are several types of window seals, including:
Bubble gasket seals
Wedge gaskets
E-gaskets
These seals are installed around the opening of the window or door, or around the glass panes themselves.
Causes of Window Seal Failure
Window seals can fail for various reasons, but the primary cause is simply the passage of time. Over a long period, the seal can flatten and lose its effectiveness. Other factors that contribute to seal failure include:
Temperature changes causing the seal to expand and contract
Solar pumping, where the sun’s heat causes the glass to expand and put pressure on the seal
Shrinkage due to cold weather, causing the seal to peel away from corners and harden over time
If you notice signs of seal failure, such as condensation, mold growth, gaps in the sealant, or drafts, it may be time to replace the seals.
Can Window Seals Be Replaced?
Yes, window seals can be replaced in certain circumstances. This is a relatively simple process that typically requires minimal tools. Most rubber window seals can be removed and installed using just your fingers, pushing and clipping the replacement seal into place.
However, if you want to repair your window seal, you may be disappointed. It is often nearly impossible to find a seal that will fit into your existing profile. When window seals lose their shape or become brittle, the only option is to replace them.
How Long Do Window Seals Last?
The lifespan of window seals varies, but most UPVC window seal replacements will function for more than ten years. Many window and door manufacturers provide a 10-year guarantee, with some offering even longer warranties.
It’s recommended to inspect your window seals every 5 years to ensure they are in good condition. Signs that it may be time to replace your seals include:
Windows with condensation
Mold growing on the seals
Gaps and cracks in the sealant
Drafts coming through closed windows
Outdated or deteriorating seals
Seals that are 5-10 years old
Steps for Replacing a Window Seal
If you decide to replace your window seals, follow these steps:
Remove the old rubber seal by squeezing a portion and peeling it away. If it doesn’t come off easily, use a crafter’s blade gently.
Check the window frame for any obstructions after removing the old seal.
Start replacing the rubber seal at one corner and work your way around the window frame. The seal should slide easily into the frame’s slots.
Repeat step 3 for all four sides of the window frame until the seal completely fills the grooves.
Inspect the corners for any gaps where the two halves of the seal meet. If there are gaps, use a small amount of silicone sealant to seal them completely.
It’s important to note that while it is possible to replace window seals yourself, it’s always best to consult with a professional if you’re unsure or if the job seems too complex.
Cost of Window Seal Replacement
The cost of window seal replacement depends on several factors, including the materials and labor involved. The cost of materials is relatively low, with a good quality UPVC window seal replacement costing between $10 and $15 per window.
Labor costs can vary depending on your location and the complexity of the job. You should expect to pay between $40 and $50 per window, with a minimum service charge for the visit. In total, the cost of window seal replacement is likely to be between $50 and $65 per window.
While it may be tempting to try to replace the seals yourself to save money, it’s important to weigh the potential risks and benefits. Attempting a complex job without the proper knowledge and tools can lead to further damage or safety issues.
When to Replace the Entire Window
In some cases, replacing the window seals may not be enough to solve the problem. If the window frame is damaged or the seal failure is extensive, it may be necessary to replace the entire window. Signs that it’s time to replace the window include:
Significant damage to the frame
Difficulty opening and closing the window
Excessive condensation or fogging between panes
Outdated or inefficient window design
When deciding whether to replace the seals or the entire window, it’s best to consult with a professional who can assess the condition of your windows and provide recommendations based on your specific needs and budget.
In conclusion, replacing rubber seals on windows is a viable option for maintaining the efficiency and longevity of your windows. By understanding the causes of seal failure, recognizing when it’s time to replace the seals, and following the proper steps, you can ensure that your windows continue to function optimally for years to come.
