Frequently Asked Questions

Question 1: Should I replace my windows all at once?

If you’re looking to update your windows for aesthetic or energy-efficiency reasons, replacing all of them at the same time can provide substantial benefits. Often, larger jobs like these will cost less, as you can bundle many of the expenses of a window replacement and can frequently get great deals on purchasing many windows at once.

Question 2: How long does window installation take?

Many window replacements or installations can be handled in a single day or even a few hours. However, this depends on how many windows are being installed and the level of complexity the windows present. It’s best to expect it to be a two-day job.

Question 3: Is it more cost-effective to replace broken glass or a whole window?

If there are no other issues with the window and only the pane has been damaged, replacing a glass pane makes more financial sense. However, if the window is old, outdated, or poorly insulated, you’ll save a lot more by replacing the entire window.

Question 4: What is the best time of year to replace windows?

Replacing in early spring is a great choice, as weather rarely impacts scheduling and ensures you get your installation done promptly. However, windows often see price reductions and sales starting in the fall, which can save you money.
