Replacement Window FAQ: Should I Replace or Repair a Broken Seal?

If your window has a broken seal, it can be tempting to put a quick band-aid fix over it rather than going through the process of replacing your window. It is human nature to want to take the fastest, easiest and often least costly route – but is it the right thing to do? Sometimes, a repair is the right solution, for example, a creaky door hinge or one broken roof shingle. But when it comes to your windows, is a broken seal cause for concern and a simple repair job? Or does your window need to be replaced altogether?

The short answer is it is on a case-by-case basis. In this article, we will be going through the different broken seal scenarios and providing expert advice on whether you can repair the broken seal, or whether it is time for a window replacement. We can do this by asking three important questions. But first, let us go over the possible signs of a broken window seal.

5 Signs of a Broken Window Seal

  • Foggy windows
  • Drafts around the window area
  • Irregular temperatures in the room
  • Damaged window frames
  • Windows are hard to open and close 

Now, onto the three most important questions to ask to determine if you can repair or you need to replace your broken window seal. 

How Old is the Window?

The age of your window is one of the best ways to determine whether a broken seal can be fixed, or whether a replacement window is necessary. You also should consider whether the warranty is enforceable. If the window is covered by a warranty, you may be able to contact the manufacturer for a replacement sash with new insulated and Low-E glass, as many manufacturers offer a 20-year or longer warranty. 

However, if your window is part of a new home, many manufacturers these days shorten the warranty period to avoid future material liabilities. It is worth mentioning that if the warranty has expired and your window needs a new sash, this option might be the less expensive route than replacing the whole window. 

What Type of Window Do You Have?

The type of window you have, as well as if it has a glazing bead, will also determine whether the broken seal can be repaired or if you need a window replacement. Most double-pane IGU (Insulated Glass Unit) windows have a glazing bead, which is a clip that holds the glass firmly in place and attaches to the sash. If the window with the seal failure has a glazing bead, it might be possible to remove it along with the glass, and then have the glass replaced with a new sealed IGU. 

If your window does not have a glazing bead, the construction of the window might prove difficult and, in some cases, impossible. If you have a window where the sash was constructed around the glass, you most likely will need to get this replaced as it can be expensive to have the sash remade. 

Have You Been Considering a Window Replacement for a While?

In many cases, a broken window seal can be repaired, but it is likely the problem will come back again. Replacing the entire window is typically the best course of action, and the best financial investment. It can be costly to replace sash and insulated glass units, so if you are looking at a replacement window project in the near future anyway, it is a smart idea to invest the money in a new window rather than repair an older unit.
