Window Replacement
in Marietta, GA
Headquartered right on Roswell Rd — not a national franchise passing through. ENERGY STAR certified windows, lifetime warranty, and a licensed Georgia crew that lives in the neighborhoods it serves.
The Window Company Marietta Calls Home
A1 Windows isn't a crew that drives in from out of town — our office sits on Roswell Rd, minutes from the Marietta Square and the historic districts that ring downtown. Many of the homes we work on here were built decades ago, long before ENERGY STAR existed, and it shows: single-pane glass, swollen wood frames, and drafts you can feel standing in the living room. Marietta's older housing stock is exactly where a window upgrade pays for itself fastest.
Because we buy factory-direct from Vytex — skipping the distributor markup that retail window companies build into their pricing — Marietta homeowners get a better-performing window without the showroom price tag. Every job, from the historic homes near the Square to newer construction toward East Cobb, is installed start to finish by our own licensed Georgia crew. No subcontractors, no strangers showing up on install day.
The A1 Windows Difference
Local, Not a Franchise
Our office is in Marietta. When you call, you're reaching the same team that measures your windows and installs them — not a national call center routing your job to a subcontractor.
Factory-Direct Pricing
Buying direct from Vytex cuts out the showroom markup. Marietta homeowners typically save 20–30% versus retail window companies for the same quality of glass and frame.
Lifetime Warranty
Manufacturer coverage on glass seals and frames, plus our own lifetime installation warranty on the workmanship. Both in writing, both honored by the same local company.
Windows & Doors for Marietta Homes
Double Hung
Two independently sliding sashes let you open from the top, the bottom, or both at once. Both tilt inward for easy interior cleaning — no ladder needed. The most common window replacement in metro Atlanta.
Casement
Side-hinged and crank-operated, casements open completely for maximum airflow. When closed, the sash presses firmly against the frame for one of the best weatherseals in the industry.
Bay & Bow
Projects outward from the wall to create panoramic views and added interior shelf space. Bay uses three panels at fixed angles; bow uses four or more for a gentle outward curve.
Slider
Sashes glide horizontally on a track — no swing clearance required inside or out. Wide glass area delivers broad views and generous ventilation with a minimal frame profile.
Awning
Hinged at the top and opening outward, awning windows let you ventilate even during light rain. Popular in basements and over kitchen sinks where other styles can't open safely.
Bow
Four or more panels arranged in a gentle outward arc — a more subtle curve than a bay window. Creates a dramatic effect that floods the room with light and expands the interior visual space.
Specialty
Round tops, geometric shapes, transoms, and custom configurations that standard windows can't match. Ideal as accent windows above entry doors or in gable ends where only a unique shape will do.
Doors
Steel and fiberglass entry doors, patio doors, French doors, and sliding doors — all installed by our own licensed crew. Humidity-proof, ENERGY STAR rated, with multi-point locking standard.
