Marietta Window Replacement provides professional aluminum windows in Marietta, GA for residential and commercial properties across Cobb County and northwest metro Atlanta. Most aluminum windows in Marietta are the ones we are taking out. Single-glazed, mill-finish frames with a felt or fin seal, installed in the boom that followed the Lockheed plant's reopening, and they are still in service on thousands of Cobb County houses.
Those windows have no thermal break at all. The frame is a continuous metal path from the outside air to your living room, which is why they sweat in January and why the interior sill under them is often the only water-stained wood in the house. That condensation is not a humidity problem you can dehumidify away. It is a surface-temperature problem built into the profile.
Modern architectural aluminum behaves differently. Either a polyamide strut, or a pocket that is poured and then debridged, separates the outer and inner halves of the frame, and the resulting unit can hit respectable numbers. It is also the only frame material that comfortably carries very large sash without a visible mullion.
Here is where Marietta differs from a northern market. At 2,531 heating degree days, the U-factor penalty that aluminum still carries relative to vinyl or fiberglass costs less over a year than it would in Chicago or Denver, so thermally broken aluminum is defensible on a residential job in Cobb County in a way it is not up north. That does not make it the right default. It makes it a real option instead of an automatic no.
We recommend it for contemporary houses where the sightline is the design, for tall stair and gable glass where the span is the problem, and for anything with a commercial character. We recommend against it for a straightforward ranch replacement, where you pay for structural capacity you do not need and give back a little performance for the privilege.
If your existing aluminum frames are sound and the problem is single glazing, ask whether the sash can be reglazed rather than replaced. On some 1970s residential lines the answer is genuinely yes, and it costs a fraction of a new unit. On most it is no, because the glazing pocket was never dimensioned for a sealed unit, and anyone who tells you otherwise is guessing.
Watch the interior condition of the frame during a walkthrough. Corrosion at the corner keys, a sill track packed with two decades of pine pollen and grit, and rollers that have worn through the track bottom are all signs the unit is finished regardless of what the glass is doing.
When we quote a replacement over aluminum, we quote full-frame removal down to the rough opening on at least the openings that face weather. Setting a new insert inside a corroded aluminum frame hides the condition instead of fixing it, and you inherit the old frame's leakage path along with a new warranty that does not cover it.
Our licensed and insured team brings the right materials and equipment to every job — compression gasket, interlocking meeting stile, fusion-welded corners, pultruded fiberglass, warm-edge spacer, polyamide thermal break — and backs the work with a written workmanship warranty. We serve Marietta and nearby communities including Smyrna, Kennesaw, Acworth, Powder Springs.

Materials, equipment and how we do aluminum windows
The difference between aluminum windows that lasts and aluminum windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with compression gasket, interlocking meeting stile, fusion-welded corners, pultruded fiberglass, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Marietta job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in Cobb County and northwest metro Atlanta means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Marietta Chooses Marietta Window Replacement
- ✓We put the air-leakage rating at the top of the quote. In a county with a short winter and a long humid summer, the gasket is the only specification that returns something in both seasons.
- ✓We measure the clear opening in every bedroom before quoting. On the wide, short openings of Marietta's 1960s ranches, an insert can drop the escape opening below the code minimum without anyone noticing.
- ✓We flash behind the brick. On veneer houses the head flashing has to lap the water-resistive barrier rather than get caulked to the first course, and we will tell you if the brick will not allow it.
- ✓We price the smaller job when the smaller job is right. Fogged sealed units get reglazed, dragging patio doors get rollers, and tired entry doors often get a weatherstrip kit rather than a new slab.
