How To Repair Damaged Double-Pane Windows

Tips In Repairing A Broken Double-Pane Window

Repairing double-pane windows should be done immediately even if you don’t think it’s damaged that bad. The thing is, a broken double pane window can be the culprit behind the condensation in your home.

Double-pane windows are life-savers, but you wouldn’t want a broken one to mess up your home or any space. Once seals in the glass are damaged, it immediately loses its function. Results may immediately escalate from condensation to damaged interiors and heightened energy costs. 

A Double-Pane Window’s Anatomy

Replacing the broken window glass only may not guarantee the best fix. Double-pane windows need to be inspected properly because damaging the glass also breaks the whole factory seal. 

A double-pane window, as the name suggests, consists of two glass panes that are assembled with a space in between. This space has air suctioned from it, which is then filled with an inert gas, usually of argon or krypton. This enables a slow passage of heat as inert gases are less heat-conductive than air. An assembly like this is called IGU or an Insulated Glass Unit.

This is why if an IGU breaks, it’s not only the glass that is damaged, but also the whole assembly of how the two glass panes operate. Just fixing glass won’t make a double-pane window work the way it used to.

Can I DIY It?

Double-pane window repair can be DIY-ed on limited stages only. For one, you can learn how to  remove the entire double pane window from the frame instead of hiring someone else to do it for you. Here’s a step-by-step process:

Step 1 – Disassemble the Sash

With a screwdriver, carefully unscrew the sash from the frame. Locate the other screws at the corners of the sash that hold it together and unscrew them too. 

Step 2 – Apply Pressure

Apply pressure on the sash to pull it out of the frame. Pull the sash apart from each other and then yank the gasket off the pane.

Step 3 – Bring It to a Specialist

Once you’ve removed it, bring it to the window specialists so they can properly assess the damage and fix it properly. 

Cost of Repair

The cost of a double-pane window glass repair averages at $170-$180, which is $100 higher than single-paned ones. This is because of the extra labor cost for the IGU function.

The cost can also depend on different factors such as additional labor costs, type of windows, or additional damaged parts that should be repaired. Also, there will be instances that it’s better to replace the whole window. You should ask an expert’s advice further on this.

If your window has a wooden frame, expect that it’s a little pricier. Vinyl or aluminum-paned windows are generally $20 to $25 cheaper than wooden-framed windows.

Better insulation starts and ends with high-quality double pane windows. Window glass is the part that is most vulnerable of breakage and damage, that’s why you should only be trusting the experts on that.

Vinyl windows are a popular type of window that is known for its durability, low maintenance, and energy efficiency. Over time, however, vinyl windows may develop issues that require repair.

Vinyl window repair or replacement can typically be done by a professional contractor or window repair company. The repair process may involve:

  • Removing the damaged window or glass pane.
  • Repairing or replacing any damaged parts of the window frame or hardware.
  • Installing new glass or sealing the window to prevent drafts.
  • Testing the window to ensure that it is functioning properly and is secure.

The cost of vinyl window repair will depend on the extent of the damage and the specific repair that is needed. In some cases, it may be more cost-effective to replace the entire window rather than to repair it. A professional contractor or window repair company can provide guidance on the best course of action for repairing or replacing damaged vinyl windows.
