Window Door Contractors FAQs, answered by experts

Window seals don’t last forever, so they’ll inevitably fail for one reason or another. One of the most common reasons is the expansion and contraction of the glass. When the glass gets warm from sunlight, it expands and adds pressure to the seal; at night, as the glass cools, it contracts. This process, day in and day out, can eventually cause the seal to fail. Other common sources of failure include the house settling over time, chemicals that damage the seal when repainting windows, and incorrect window installation.

Pet-resistant, vinyl-coated polyester is one of the strongest window screen materials available, with some manufacturers touting a 7x increase in strength compared to standard fiberglass screens. Stainless steel security screens are also extremely strong, but they’re not suitable for coastal areas due to the risk of corrosion from salty sea air. If sea air isn’t a concern, stainless steel is extremely tough.

Window screens can take anywhere between 10 minutes and an hour to replace, depending on the complexity of the replacement and the accessibility of the window. Replacing the screen inside an existing frame normally takes longer than replacing an entire screen, frame and all, if you purchase a prefabricated screen already mounted on the frame.

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.

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.
