Frequently Asked Questions
How Much Does It Cost To Replace Windows?

How Do You Measure For Replacement Windows?
We’ll have a technician remove the functional features and glass parts of your old windows, taking care to measure the spaces where your replacements will go. Most projects we come across don’t even require our expert to get inside; all the measurements can be done from the exterior.
Window Repair Versus Replacement?
Depending on whether or not your window is damaged, and the extent of that damage; you might have to replace your windows completely. If the moving parts or the frame is damaged somehow, replacement is the way to go. If they refuse to open or close smoothly, you still might want to consider a replacement. Repairing a window can be more expensive than replacing one, so consider why you want new windows.
