It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

• Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

• Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

• Window Details: The size, type, and material of the window affect the price.

• Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

• Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window. 

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.
