If you’re a homeowner asking how to replace window seals, you’ll want to ensure you do your research before tackling this project! Replacing window seals is not always an easy task and the process has plenty of room for error. Even the smallest mistake can then result in thick condensation settling on the interior glass, dust between window panes, or gaps around the window itself!
To replace a rubber window seal, use needle-nose pliers to pull up the old seal and remove it from the glass pane. Add some high-quality glass glue to pressure points around the window. Next, apply a new rubber seal around the pane using an insert tab. Tap the seal into place and cut off the excess with a razor blade.
The average cost of window seal replacement is between $70-$120.
To ensure you replace window seals properly without damaging the window or end up with even bigger gaps than before you began, note a few added tips on this project. You might also consider why it’s often best to leave this job to the pros, and how often you might need to perform window seal repair around your property.
Homeowners especially might also consider some advantages of new windows around the house! If many window seals are broken or several windows need other repairs, this can be a great opportunity to update your property with stunning new window installation.
To fix a broken window seal, first ensure you have all the tools needed for the job. This includes needle-nose pliers, a razor blade for scraping away damaged sealant and new seal residue, glue made for glass, and a new window seal! You can then follow this process for fixing and replacing a broken window seal in your home:
Damaged or missing sections of window seals are not just a minor inconvenience. Those seals close off that gap between the window pane and its frame. Outside heat and cold, humidity, and even bugs don’t need much of a gap in the seal to get into your home’s interior!
Damaged window seals are one major reason why you might notice condensation or fog on the windows, especially when there is a major difference between interior and exterior temperatures and humidity levels. As warm air on one side of the window hits cold air on the other, humidity then clings to the glass, creating condensation.
Most of today’s windows are also double-glazed, meaning there are actually two panes of glass making up the window itself. The gap between these two panes is typically filled with argon or krypton gas. Once a seal is damaged, this allows that gas to leak out which then risks distortion of the window panes.
You might then notice a pane bowing inward or outward slightly, as it’s no longer supported by that gas. This lack of support can even lead to glass chipping or cracking!
Seal failure can also spike your utility costs throughout the year. If the seals fail to keep out hot or cold air or keep in your heated or cooled air, your home’s HVAC system will cycle on more often and stay on longer, trying to maintain your desired temperature. Outside humidity getting into the home can also mean more wear and tear on a home’s dehumidifier.
Broken window seals mean increased energy costs, bothersome condensation, an uncomfortable interior space, and even pest infestation! Ignoring broken seals means that drafts, humidity, and pest infestation will only get worse with time. Rather than putting off seal replacement, a homeowner should repair this issue as quickly as possible, or consider replacing those windows altogether.
Unfortunately, the answer is yes, broken window seals are notorious for letting in cold air, as said. If your home feels drafty in wintertime and stays cold no matter how much you crank up the thermostat, this is a sign that the window seals need an inspection and replacement.
In some cases, you might even be able to spot broken seals by running your hand around the window and looking for cold spots! Remember that those cold spots mean cold air in the home during wintertime, almost as if you were keeping the window open. Rather than tolerating that cold air, keep your interior spaces comfortable and your utility costs low by repairing or replacing broken window seals when needed.
One reason that windows with broken seals create condensation is that those seals let moisture seep in between window panes. In some cases and depending on the surrounding temperature, that moisture can evaporate or dry up.
However, when there is an extreme temperature difference between both sides of the window, that moisture can then condensate. That condensation might stay between the panes or it might seep out and then end up on the interior window glass.
It’s never recommended that you ignore repeated condensation. A home’s walls and paint on the walls absorb that excess moisture, risking peeling paint, wood rot, and damaged framing and mold growth. If that condensation should drip down the wall, it can also risk mold and mildew underneath carpeting, and even damaged floorboards.
Window seals should be replaced or repaired as often as needed! To help you understand when your home’s window seals might need replacing, consider some reasons why they often degrade. You can then determine your home’s risk for damaged seals and have a better idea of how often they need inspection for potential replacement:
Whether or not you should simply replace a window with a broken seal rather than attempt repairs depends on the window’s age, the extent of damage, and if it might not be time to replace those windows anyway. For example, ignoring the seal around a double-glazed or triple-glazed window can allow dust and other debris to settle between those panes. It’s often difficult if not downright impossible to remove that dust, so replacing the window might then be your best choice.
If window seals are damaged due to heavy storms, harsh sunlight, or similar factors, note that the window glass might also be worn down or show lots of etching and scratching. Replacing damaged windows ensures they look their best while reducing the risk of cracking and breakage.
Window glass also tends to degrade with age, while frames might also pull out of place so that gaps then form. If the windows are more than 10 years old, it might be time to replace them altogether, to ensure the glass is strong and the frame fits snugly.
Especially damaged seals and etched and scratched glass are indicators that it’s time for new window installation around your home. However, damaged windows aren’t the only ones needing replacement! Note some considerations to keep in mind about when and why it’s time to start thinking about new residential windows.
