Window Door Contractors questions, answered by experts

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.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.

Most windows last for 15 to 30 years, depending on the frame material and the glass quality, but most will require repairs during that time. Windows gradually lose efficiency, so it’s usually best to have a window repair technician inspect and service your windows every five to 10 years. You should also repair your windows if you experience the following:

  • Leaks

  • Drafts

  • Difficulty opening or closing

  • Sudden increases in heating and cooling bills

  • Outdoor noise becomes more audible

  • Signs of physical damage

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.

Whether you should repair or replace a screen door depends on the type and extent of the damage. It is easy and economical to repair a small tear in the mesh using a widely available DIY patch kit. However, if there are large tears, multiple damaged spots, or if the screen is made of a specialized material, replacing the entire screen mesh might be a better long-term investment for a tidier appearance. You should also consider the condition of the frame; if the frame itself is damaged, it's likely time to replace the entire door. Other factors to weigh include whether you want a new style or need a more durable door.
