Window & Door Replacement
in Kennesaw, GA
Twenty-year-old builder windows fog, stick and leak. We replace them across Kennesaw with factory-direct Vytex windows and ProVia doors, a short drive up I-75 from our shop.
Kennesaw’s Window & Door Replacement Contractor
Kennesaw grew fast in the 1980s, 1990s and 2000s, and most of those houses went up with builder-grade windows. Twenty-plus years later, those are the windows fogging between the panes, sticking in their tracks and letting summer heat pour into upstairs bedrooms.
We replace them throughout Kennesaw, from the established streets around Historic Downtown and the Southern Museum to the subdivisions off Chastain Road, Jiles Road and Barrett Parkway. Every price is firm and in writing, and every install is handled by a Georgia-licensed crew supervised by A1.
We work across Kennesaw, including Historic Downtown Kennesaw, Barrett Parkway and Town Center, Kennesaw State University area, Chastain Road corridor and Kennesaw Mountain.
Does Your Kennesaw 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.

Kennesaw Homes: Matching Style With Performance
Most Kennesaw homes are two-story traditionals, ranches and townhomes built in the last forty years, with plenty of standard-size double hung openings and a sliding door to the back deck. That consistency is good news: replacement windows fit the existing openings cleanly, and a whole house can usually be done in a day. Older homes near downtown and the farmhouse-style infill going up today need more custom sizes, and we measure every opening individually either way.
Double Hung windows
The workhorse for Kennesaw two-stories; tilt-in sashes make second-floor glass easy to clean.

Sliding Door
Swap a sticking builder slider for a Vytex Signature patio door on adjustable tandem rollers.

Slider windows
A clean fit for ranch and basement openings that are wider than they are tall.

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.
The A1 Windows Difference
Local and owner-supervised
Our office is on Roswell Rd in Marietta. The team that measures your Kennesaw 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 Kennesaw’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.
Upstairs rooms in Kennesaw's two-story homes take the brunt of the afternoon sun; Low-E glass and warm-edge spacers keep them closer to the temperature downstairs.
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.
