Before you choose
What to compare
Use these points to compare any replacement window provider, whether or not it appears on The Top 10 Experts.
U-factor
Insulating value
Lower U-factor means less heat loss. Look for ENERGY STAR ratings for your climate zone.
SHGC
Solar heat gain
Lower SHGC blocks more heat from sunlight, useful in hot climates.
Frame
Frame material
Vinyl is affordable and low-maintenance. Fiberglass and wood cost more but offer other strengths.
Install
Full-frame vs. insert
Insert windows fit existing frames. Full-frame replacement costs more but fixes rot and air leaks.
Common questions
How long does window replacement take?
Installation often takes one to two days for a typical home, after a lead time for custom-made windows.
Are energy-efficient windows worth it?
They can cut drafts and energy use. Payback depends on your climate and current windows.
Should I get multiple quotes?
Yes. Prices vary widely between installers for the same product.
