Can windows be resealed? It’s a question nearly every homeowner asks. When you begin noticing drafts, higher energy bills or frustrating fog between your glass panes, your first thought might be to fix window seal issues yourself. After all, maintaining functional windows is a big part of keeping your Muscle Shoals home energy-efficient and comfortable
The short answer is: it depends on where the seal is broken. Resealing windows is a practical DIY project in some cases, but in others, it’s simply not an effective, sufficient or lasting fix.
Understanding The Two Types of Window Seals
Before deciding on actions to take, it’s important to identify which seal has failed. A typical window unit has two primary areas where an air seal is crucial:
The Perimeter Seal (Caulk and Weatherstripping)
This is the seal around the window frame, encompassing where the frame meets the exterior siding or trim, as well as where the moving parts of the window meet the frame. This seal prevents drafts and water from entering your home.
- Signs of Seal Failure: Cracked, peeling or missing caulk around the frame, or noticing a significant draft coming from the edges.
- The Fix: This is where DIY window resealing is most effective. You can easily learn how to seal a window from the inside or the outside by removing old, failing caulk and applying a fresh, high-quality exterior-grade sealant.
The Insulated Glass Unit (IGU) Seal
This is the internal seal that holds together the multiple panes of glass (as in double-pane windows) and keeps the argon gas trapped between them.
- Signs of Seal Failure: Fog, streaks or persistent condensation trapped between the glass panes.
- The Fix: You cannot effectively fix window seal failure in an IGU with a simple DIY project. Once this seal is broken, argon gas escapes and moisture infiltrates. Repairing this requires a professional technician to replace the entire sealed glass unit, which can be very expensive when compared to the window’s remaining lifespan.
What Happens When a Window Seal is Damaged?
When your window seal is damaged, there is a greater chance of things like bugs being able to enter the home, leaks developing or even increases in your energy bill. If your in-home comfort is down but your expenses are up, there’s a good chance one or more of your windows have damaged sealing. When it comes to identifying the cause and your next steps, we’ve got all the information you need.
How to Tell If a Window Seal Is Damaged
There are some clear indicators for when your windows need resealing. The most prominent sign is that your window is newly drafty. You may also notice an increase in window fogginess, condensation and even leaks. Check for physical wear and tear like cracked or dry caulk around your windows.
Can You Reseal a Damaged Window Seal?
In most cases, no. Not only is it unlikely that you will be able to fully repair a damaged window seal, but attempting to do so can possibly lead to further damage to your home. It can also be more cost-effective to replace the entire unit, as opposed to pursuing a repair.
What To Do With a Damaged Window Seal
While DIY window resealing or getting help from a specialist are options, results aren’t guaranteed. Especially with more complicated window types, like double-glazed and storm, it can be an uphill battle. Plus, even if the resealing goes well, there can be other underlying issues with your windows. For these reasons, replacement windows are often the best option. Especially when you consider that Window World windows come with a lifetime warranty.
Other Signs Your Windows May Need Replacement
Window seal damage may be only one of many issues you’re facing. Other reasons for window replacement can include:
- Rotting and destroyed wood in the window frames
- Difficulty opening and/or closing your windows
- A lack of soundproofing from single-pane windows
