Marietta Window Replacement provides professional glass repair & sealed units in Marietta, GA for residential and commercial properties across Cobb County and northwest metro Atlanta. A fogged window is usually a repair, not a replacement, and the trade is comfortable with homeowners not knowing it. If the sash operates, the frame is square and the hardware works, what failed is the sealed glass unit inside it, and that unit can be replaced on its own.
The failure itself is straightforward. A desiccant-filled spacer holds the two lites apart, and the perimeter around it is closed with a primary butyl seal backed by a secondary structural sealant. Over years of thermal cycling that seal admits moisture, the desiccant saturates, and the first humid morning after saturation you get condensation between the panes. Once it starts it does not reverse.
Marietta works these seals from both directions, which is the part that surprises people. In a summer where outdoor dew points sit near seventy degrees and the house is held at seventy-two, the vapor drive pushes inward. In winter it pushes the other way. A climate with 2,051 cooling degree days and 2,531 heating degree days reverses the load on that perimeter seal twice a year, every year.
What we do about it is a measurement and an order. We record the sight-line dimensions, the overall unit thickness, the glass thicknesses, the spacer type and any low-E coating and its surface number, then order a matching unit and reglaze the sash. On most residential windows this runs a fraction of a full replacement and takes one visit once the unit arrives.
Two upgrades are worth taking while the sash is open. A warm-edge spacer, structural foam or stainless rather than the aluminum box the original almost certainly had, which raises the edge temperature and lengthens the life of the new seal. And a modern soft-coat low-E if the original glass was clear, which changes the room's summer comfort more than anything else you can do for the money.
Breakage is the other half of this work. Storm debris, a thrown ball, a settling frame. If the broken lite is in a safety-glazing location, beside a door, at a stair or low to the floor, it comes back as tempered or laminated regardless of what was in there before. We will board an opening the same day and glaze it when the unit arrives.
One thing not to do is replace an entire window because of fogging alone. The energy penalty from a failed seal is smaller than most people assume, mostly the loss of the argon fill and a little edge conduction. It is a cosmetic problem with a cosmetic price attached to fixing it.
If your windows are original 1960s aluminum single glazing and one lite breaks, that calculation changes. Reglazing a frame with no thermal break and worn hardware is money spent on the wrong part of the assembly, and we will say so.
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 glass repair & sealed units
The difference between glass repair & sealed units that lasts and glass repair & sealed units 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.
