"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

Windows questions, answered by experts

Folding window installation costs about $1,600 on average, ranging from $500 to $3,000. The cost factors of this project include the size, the type of folding windows, the number of panels, and the type of glass. Different types of folding windows include:

  • Standard folding window: $200 per linear foot

  • Glazed folding window: $240 per linear foot

  • Standard folding window and swing door: $1,000 per linear foot

  • Folding window and sliding door: $2,000 per linear foot

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.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

Impact windows are absolutely worth the money if you live in an area prone to hurricanes. Though expensive, impact windows are built to withstand hurricane winds up to 200 mph and theoretically won’t break even if flying debris, such as mailboxes and lawn chairs, is smacked against the glass. A single broken window during a hurricane can destabilize the pressure inside your home, which can cause walls and the roof to collapse.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.
