Window Treatments FAQs, answered by experts

The rough opening refers to the framed space in the wall where the window will be placed. That means the full size of the space will be filled with both glass and frame once the new window is installed. For a standard window, a rough opening adds 1/2 inch to 3/4 inch to both the length and width.

Deciding whether to repair or replace a window depends on the specific issue, the window's age, and the cost-effectiveness of the solution.

Repair is often better for:

  • Minor issues such as a single broken glass pane, a stuck window, or small leaks. Repair is typically more affordable for isolated problems.

Replacement is the better long-term solution for:

  • Major problems like deteriorating or rotting frames, significant leaks, or drafts.

  • If your windows are over 15 years old, as repairs may only be a temporary fix for an aging unit.

  • If you have a widespread problem affecting several windows.

Arched windows are slightly more expensive than standard rectangular ones, but they only cost $50 to $100 more per window. However, adapting a rectangular wall opening to accept an arched window can add $200 to $400 to your total, making them a more expensive option over sticking with a standard window replacement.

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.

The type of casement window you have depends on where the hinges are located, the number of sashes, the style, and how the windows open. Single casement windows are popular casement windows that use a handle or crank to open. If you have two casement windows side by side, you likely have double casement windows. 

Windows that swing inward can tip you off to having in-swing casement windows, while windows that open from the bottom and swing outwards are top-hinged. If you can open your windows by pushing them outwards like a door, you may have a type of push-out window.
