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 Greater Atlanta homeowners pay between $400 and $900 per window installed, depending on the style, size, and number of windows replaced. Because we buy factory-direct from Vytex — no showroom, no middleman — our prices typically run 20–30% below retail window companies. 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?
You get two warranties in writing: a manufacturer lifetime warranty from Vytex covering glass seals, frames, and hardware, and our own lifetime installation warranty covering the workmanship. If a seal ever fails or a window ever leaks because of how it was installed, we come back and fix it — no charge, no argument.
