Does Your Cumming Home Need New Windows?
Drafts you can feel
Air moving around the sash or frame on a cold or windy day means the seals and weatherstripping have worn out.
Fog between the panes
Moisture inside the glass means the insulated seal has failed and the gas fill is gone.
Sashes that stick or drop
Windows that won't open, won't stay up or won't lock usually have worn balances or warped frames.
Rooms that run hot or cold
Upstairs bedrooms that never match the thermostat are often losing the fight through old glass.
Outside noise
Road and neighborhood noise that carries indoors drops noticeably with tight, insulated windows.
Soft or rotting frames
Peeling paint, soft wood or crumbling sills mean water has been getting in for a while.

Cumming Homes: Matching Style With Performance
Most Cumming homes are two-story traditionals and craftsman plans with double hung windows, arched transoms, two-story family rooms and sliding doors to the deck, and lake homes add big picture walls and walkout basements. Many neighborhoods have HOAs, so we match colors and grid patterns and provide the specifications for approval.
Windows & Doors for Cumming 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.
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.
Picture
A fixed pane with no moving parts, so the frame stays slim and the glass area is as large as possible. Pair one with operable windows on either side for a wall of light with ventilation exactly where you want it.
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.
Bay
Three panels set at fixed angles project outward from the wall, creating panoramic views and a deep interior shelf or window seat. A statement piece for living rooms, kitchens, and dining nooks.
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.
Garden
A small greenhouse that projects out from the kitchen wall, with a glass top and sides that bathe herbs and plants in sunlight. Side vents open for fresh air while the glass shelf doubles as extra counter space.
Round Top
An arched top brings a classic, elegant shape to an entryway or the top of a double hung. Available as a fixed accent or paired with operable units below, in half-round, quarter-round, and eyebrow profiles.
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.
Entry Doors
Steel and fiberglass entry doors with insulated cores and multi-point locking, built to shrug off Georgia humidity. Choose woodgrain finishes, decorative glass, and sidelite layouts to match your home.
Patio Doors
Wide glass panels connect your living space to the deck or backyard while sealing out summer heat and humidity. Available in sliding or hinged configurations with low-profile sills.
French Doors
Two hinged doors that swing open together for a grand, full-width opening onto the patio. Traditional styling paired with modern multi-point locks and ENERGY STAR glass.
Sliding Doors
Two or three glass panels on a track, up to 8 ft wide per pair, with one panel gliding past the other. The most glass and the most light you can put in a wall without a swing.
The A1 Windows Difference
Local and owner-supervised
Our office is on Roswell Rd in Marietta. The team that measures your Cumming home is the team you call afterward, not a national call center.
Factory-direct Vytex pricing
We buy windows direct from Vytex, so a whole-house project costs far less than the same quality through a showroom retailer.
Two warranties, named separately
Vytex's Limited Lifetime warranty on the windows, plus A1's 2-Year Workmanship warranty on the installation, both in writing.
Energy Efficiency for Cumming’s Climate
Georgia’s long, humid summers make solar heat the biggest energy drain in most homes, and our winters still bring cold snaps that find every gap. The Vytex windows we install pair Low-E coatings with argon gas fill and warm-edge spacers, so less heat gets in during summer and less escapes in winter.
North of the metro, Cumming sees cooler winter nights; argon-filled glass and warm-edge spacers help in both seasons.
Turns back solar heat and UV while letting daylight through.
Insulating gas between the panes slows heat flow.
Keep the edge of the glass warmer and drier in winter.
More insulation and quiet where you want it.
