Marietta Window Replacement provides professional double-hung windows in Marietta, GA for residential and commercial properties across Cobb County and northwest metro Atlanta. We sell more double-hungs than anything else and they are not the best performer in our catalog. Both facts are true at once, and a contractor who will not tell you the second one is selling you a look rather than a window.
The geometry explains it. A double-hung has two sash that slide vertically past a jamb, sealed by weatherstrip that has to be loose enough to let them move. Add the meeting rail where the two sash pass each other and you have three seal lines that work by wiping rather than by squeezing. A casement, by comparison, has one seal that gets compressed by the hardware when you lock it.
That difference shows up in the leakage column of the label. Good double-hungs land in the 0.10 to 0.20 cfm per square foot range. Good casements land near 0.02. In a market where heating and cooling loads are almost the same size, that gap is money in both directions.
So why do we install them by the hundred in Cobb County? Because they are the right window for the house. On a colonial or a two-story traditional off Roswell Street, a casement's outswing sash reads wrong from the sidewalk. Because both sash tilt in, a homeowner can wash a second-story window from inside instead of hiring a ladder crew twice a year. And because they never swing into a walkway, porch or deck rail.
When we do quote them, the specification is not negotiable on two points. The meeting rail needs an interlocking profile, not two flat surfaces meeting with a strip of foam between them. And the balances should be block-and-tackle or constant-force coil rather than the cheapest spiral balance, because a sash that will not hold its position eventually gets propped, and a propped sash does not seal at all.
Ask about the sash lock too. A cam lock that draws the two sash together pulls the meeting rail into contact and converts a wiping seal into something closer to a compression seal. It costs almost nothing and it is the single cheapest performance upgrade on this style of window.
One local caution about the older ranch openings. If your bedroom windows are wide and short, a double-hung cuts the available clear opening in half vertically, and the top sash does not count toward escape. On a thirty-six-inch-tall opening that arithmetic can fail the twenty-four-inch minimum clear height outright.
Our honest recommendation for most Marietta houses is a mixed order: double-hungs on the street elevation and anywhere the sash has to be washed from indoors, casements or fixed units on the back and the sides where nobody is looking. You get the appearance you want on the elevation that is seen, and you stop paying for it on every utility bill for the next twenty years.
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 double-hung windows
The difference between double-hung windows that lasts and double-hung 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.
