Why Replace Your Windows?

Old, inefficient windows cost you money every month and hold back your home's potential. New windows pay for themselves — and then some.

Lower Energy Bills

ENERGY STAR windows can reduce heating and cooling costs by 12–33%. Stop paying to heat the outdoors — modern insulated glass keeps your home comfortable year-round.

Increase Home Value

Window replacement delivers a 70–80% return on investment — one of the highest ROI home improvements you can make. Buyers notice new windows immediately.

Enhanced Comfort

Eliminate cold drafts, hot spots, and outside noise. Dual-pane insulated glass maintains consistent temperatures in every room, every season.

UV Protection

Modern Low-E glass blocks up to 99% of harmful UV rays, protecting your furniture, hardwood floors, and artwork from fading and sun damage.

Got Questions?

Window Replacement FAQs

How much does window replacement cost in the Atlanta area?
Most standard replacement windows we install across Greater Atlanta come in between about $680 and $1,000 each, installed, in double-pane Low-E or triple-pane glass; a loaded premium window (top series, custom color, grids) can reach about $1,400. Because we buy factory-direct from Vytex, with no showroom and no middleman, our prices typically run 20–30% below showroom retailers for comparable windows. We give you a firm, written quote after measuring your home; there are no surprise charges on installation day.
How long does window installation take?
A typical home with 10–15 windows is completed in a single day. Our crew arrives in the morning, installs every window, and leaves your home clean before they go. Larger projects may run into a second day, but we confirm the schedule with you before the job starts so there are no surprises.
Will window replacement make a mess of my home?
No. Our crew protects your floors and furniture, removes the old windows, and hauls away every scrap of debris before leaving. Because we replace windows from the exterior wherever possible, disruption inside your home is minimal — most rooms are back to normal within minutes of the install.
Are your windows ENERGY STAR certified?
Yes. Every window we install is ENERGY STAR certified for the Southern climate zone, which covers Georgia. Our Vytex Potomac windows are rated for low solar heat gain — important for Georgia summers — while still letting in natural light. Many homeowners see a noticeable drop in their cooling bills within the first season.
What warranty do A1 Windows come with?
Two warranties, in writing and named separately. Your windows carry the Vytex Limited Lifetime Warranty: frame and sash, hardware, screens and the insulated-glass seal for as long as you live in the home, with residential glass breakage covered and transfer to the next owner. Your installation carries A1's 2-Year Workmanship Warranty: if anything about how we installed your windows isn't right, from a draft to a stuck sash or a leak at the trim, we come back and fix it at no charge.
