Window Treatments FAQs, answered by experts

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

Casement window types differ from standard windows in that they have a hinge on the side or the top of the window so that it can open inwards or outwards. If your casement windows open upward, they usually have a crank to operate them. Casement windows with side hinges typically operate like a door, opening and closing without a crank.

Yes, replacing windows can boost your home’s resale value by improving its curb appeal, energy efficiency, and comfort. The return on investment (ROI) varies depending on the types of windows you install, but most homeowners see an ROI of around 60% to 70% of the cost of the window installation, according to the Remodeling 2024 Cost vs. Value Report. 

Yes, every window needs a lintel. The lintel is necessary for redistributing the load above the window to the walls around the window. Windows aren’t meant to support a load, so lintels are an important part of a window installation. If you go to replace your windows and discover there are no lintels, you may need a window company or structural engineer to install lintels for your new windows.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.
