Marietta Window Replacement provides professional bay & bow windows in Marietta, GA for residential and commercial properties across Cobb County and northwest metro Atlanta. Treat a bay or a bow as a room extension rather than as a window. It hangs off the wall carrying its own roof, its own floor and an insulated cavity, with four or five sealed units set across the front, and the parts that fail are rarely the glass.
That is the first thing to understand before you price one. The units themselves are ordinary casements or double-hungs. The money and the risk are in the head flashing, the roof pitch, the seat board framing and the cable or knee-brace support that keeps a projecting box from sagging away from the house over fifteen years.
On Marietta's brick-veneer ranches, the flashing detail is where jobs go wrong. The bay projects past the face of the brick, so the head flashing has to run up behind the veneer and lap the water-resistive barrier, not tuck under the first course and get caulked. Sealant alone is maintenance dressed as a detail. We open that joint properly, and if the brick will not permit it, we say so before ordering.
The roof matters as much. A bay roof in Cobb County spends its life under oaks, hickories and loblolly pines, and a low-pitch bay roof turns into a debris shelf. We build them steeper than the minimum, cap them in metal rather than shingle where the pitch is shallow, and we tell clients on heavily wooded lots that this is a thing they will be cleaning.
Below the glass, the seat board and the soffit are an insulated floor and ceiling hanging in outside air. If they are framed with a two-by-four cavity and a scrap of batt, that seat is cold in winter and clammy in August. Ours get a full-depth cavity, rigid insulation at the underside and a continuous air seal, because a bay is the one assembly where the wall around the window leaks more than the window.
For the units themselves we push casement flankers rather than double-hung ones. A bay is usually the widest expanse of glass in the room and it is often on the front of the house; using the tightest-sealing operable style there recovers some of what the projecting box costs you.
The style question is simple enough. A bay sets three units on fixed angles, commonly thirty or forty-five, around one large fixed center. A bow uses four or five units on a gentle radius, which reads softer and costs more per foot of wall. Both need the same support and flashing work.
We turn these down more often than any other product. If the wall below is failing, if the header cannot be verified, or if a homeowner wants a bay on a shaded rear elevation purely for resale, we will quote the flat replacement instead and explain why. A bay on the wrong wall is a leak with a nice view.
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 bay & bow windows
The difference between bay & bow windows that lasts and bay & bow 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.
