Marietta Window Replacement provides professional sliding windows in Marietta, GA for residential and commercial properties across Cobb County and northwest metro Atlanta. The horizontal slider is the signature window of Marietta's postwar housing, and there is a reason for that. Roughly a quarter of the city's homes were built between 1960 and 1979, and the ranch plans of those decades put wide, short openings under long low eaves.
A slider fits that shape without a mullion in the middle of the view. Every one of those original openings was fitted with an aluminum slider, and those are the units we are asked to replace most often. Glass is almost never what failed. The track is: three decades of grit, pine pollen and roller wear until the panel drags, the felt seal is gone and the sash no longer sits against anything at all.
Sliders are, by geometry, the second-leakiest style we sell, behind double-hungs and well behind casements, because the operating panel wipes past a stile instead of compressing into a gasket. We tell people that up front. We also tell them that forcing a casement into a sixty-inch-wide opening means adding a structural mullion and two sash where there used to be one clean run of glass, and that is usually the wrong trade for the house.
What makes a good one is detail work. The meeting stile should interlock, so the two panels hook into each other and hold a seal line rather than merely touching. The panel should ride on tandem rollers with stainless or nylon wheels, adjustable from the interior. The track should be sloped and weeped so water that gets in has somewhere to go, because in this climate it will get in.
Order the operating panel on the side the prevailing weather does not hit if the room allows it. On a rear elevation catching afternoon storms off the northwest, having the fixed lite take that side and the operator tucked away is worth a small amount of comfort every year and costs nothing to specify.
Two- and three-panel configurations behave differently. A two-panel unit has one moving seal; a three-panel with two operators has three, and each one is a place for air. If you want ventilation across a long wall, we would rather give you a fixed center lite with an awning or casement at each end than a three-panel slider.
Bedrooms need a check before the order goes in. A slider only gives you half its width as clear opening, so a sixty-by-thirty-six inch opening yields roughly twenty-eight inches of clear width once frame and interlock are subtracted, and the clear height is what usually fails first on these short ranch openings.
For a rental or a flip in South Cobb, a good two-panel vinyl slider with an interlocking stile is genuinely the right product. It matches the house, it costs what the property can carry, and if the track is specified properly it will still be sealing when the next owner arrives.
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 sliding windows
The difference between sliding windows that lasts and sliding 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.
