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.
- ✓We will talk you out of products. Triple glazing, impact glass for storm reasons and solar screens on shaded north walls all get argued against here, in writing, before an order is placed.
- ✓We give the supplier's lead time in writing and do not book the crew until the units are on the ground and inspected. Custom glass takes weeks, and pretending otherwise only moves the disappointment.
How It Works
A measured visit, not a sales presentation
We measure every opening, record the clear opening height in bedrooms, look at how the flashing meets the brick and check whether the existing frames can take an insert. That visit tells us which openings need full-frame removal and which do not, and it is what the quote is built from.
A bid you can compare on paper
You get the air-leakage rating, the U-factor, the solar heat gain coefficient, the frame material, the corner construction and the hardware for each unit, with the insert and full-frame options priced separately. If a competing bid leaves the leakage column blank, ask them for it.
Ordering and the wait nobody enjoys
Custom units are built to your measurements, which takes weeks rather than days. We give you the supplier's lead time in writing, we tell you when it slips, and we do not schedule the crew until the units are physically on the ground and inspected for damage.
Installation, flashing and the walk-through
The crew sets each unit plumb on shims at the load points, foams with low-expansion sealant rather than packing the gap, pans the sills and laps the head flashing behind the veneer. We operate and lock every unit with you before we leave, and we haul the old sash away.
Our Window Services in Marietta, GA
Energy-Efficient Windows
Marietta sits in a climate that refuses to pick a side. The 1991-2020 normals for Atlanta run 2,531 heating degree days against 2,051 cooling degree days, so the furnace and the compressor split the calendar almost evenly between them.
Vinyl Replacement Windows
Vinyl is the default here for a reason, and it is not price alone. A fusion-welded frame has no mechanical corner joint to open, which is the difference between a window that holds its leakage rating for twenty years and one that drifts upward every summer.
Fiberglass Windows
Pultrusion draws glass fiber through a resin bath and cures it into a hollow structural profile. The useful consequence is that the frame and the sealed glass unit inside it expand at nearly the same rate when the wall heats up, so the seal between them is not being worked every afternoon.
Wood & Clad Windows
Clad wood is a wood window wearing a metal coat. The interior is the material people buy it for, and the exterior cladding is the part that decides whether it survives twenty Georgia summers on the wall you put it on.
Aluminum Windows
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.
Double-Hung Windows
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.
Casement & Awning Windows
A casement is the tightest window most homeowners will ever own, and the reason is mechanical rather than clever. When you turn the crank the last quarter turn, the hardware pulls the sash back into a continuous gasket around all four sides and squeezes it.
Sliding Windows
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.
Bay & Bow Windows
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.
Picture & Architectural Windows
A fixed window has no hardware, no gasket that has to survive being opened, and no leakage path around a moving part. On a spec sheet it is simply the best-performing unit in the house, and on most Marietta houses it is underused.
Egress Windows
The arithmetic that gets quoted everywhere is the 5.7 square feet of net clear opening required for an emergency escape and rescue window. In Marietta that number is rarely the one that fails.
Impact & Laminated Glass
If you came to this page looking for hurricane windows in Marietta, the honest answer is that you probably should not buy them, and we would rather lose the sale than take your money for the wrong reason. Wind-borne debris requirements in the building code apply to hurricane-prone regions along the coast, where design wind speeds reach the thresholds that trigger them.
Patio Sliding Doors
A sliding patio door is the largest moving seal in a house, and on a Marietta ranch it usually sits on the rear wall facing a deck. Whatever the rest of your window package achieves, this one opening can undo a meaningful part of it.
French Doors
The usual rule is that hinged doors seal better than sliding ones, because a hinge and a latch can compress a gasket in a way a roller never will. On a single hinged door that rule holds.
Entry Doors
An entry door is judged on three things: the slab, the frame it hangs in, and the sweep at the bottom. Homeowners shop the first one.
Window Screens
Every spring somebody calls this office and asks whether tighter screens will keep the pollen out. The answer is no, and it is worth explaining properly rather than selling you something that will not work.
Glass Repair & Sealed Units
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.
Commercial Storefront Glass
Commercial glazing in this market runs from the shopfronts around the square to the low-rise office product along Powers Ferry Road and the flex and light-industrial space near Franklin Gateway. Three different building types, three different sets of problems, one framing system underneath most of them.
What Marietta Customers Say
They measured our bedroom windows and told us an insert would put the escape opening under code, which nobody else had mentioned. We paid more for full-frame on two openings and kept inserts everywhere else. The quote showed both numbers side by side and the crew cleaned up properly.
Called about fogged glass and braced myself for a whole-house pitch. What I got instead was six sealed units reglazed with warm-edge spacers, at a fraction of the other estimate. Took two visits because the glass had to be ordered, which they told us up front.
Our 1974 ranch had the original aluminum sliders in every room. They replaced the whole back of the house with casements and left the front as sliders so it still looks right from the street. The difference in the summer power bill was obvious by the second month.
I asked for hurricane windows because a salesman had scared me about storms. They explained why Cobb County is nowhere near a wind-borne debris zone and quoted laminated glass only on the two rear openings where security actually mattered. Saved me several thousand dollars and told me why.
Marietta Window Replacement installs replacement windows, patio sliding doors and entry doors throughout Marietta and Cobb County, Georgia. We fit vinyl and pultruded fiberglass frames, clad wood where the sightline matters and thermally broken aluminum where the span does, in double-hung, casement, awning, slider, picture, bay and bow configurations, and we replace failed insulating glass units in sash that are still sound.
Every bid we write leads with the air-leakage rating, because in this county that is the number that pays twice. U-factor mostly buys you a mild winter and solar heat gain coefficient mostly buys you a long summer, while the leak rate at the gasket works for you in both. Compression seals, welded corners and interlocking meeting stiles are where that number comes from.
The work reflects the housing. Close to a quarter of Marietta's homes were built between 1960 and 1979, which means wide, short openings, brick veneer to flash behind and original single-glazed aluminum sliders to remove. We do full-frame and insert replacement, egress openings in daylight basements, patio and entry door replacement, screen work and commercial storefront glazing. Smyrna, Kennesaw, Acworth, Powder Springs, Mableton, Woodstock and the rest of the northwest metro are all inside our normal service radius.
About Marietta Window Replacement in Marietta, GA
Marietta Window Replacement works the northwest side of metro Atlanta: Cobb County first, then the Cherokee, Paulding, Bartow, Douglas, north Fulton and DeKalb suburbs around it. Most of what we do is residential replacement in houses built between 1955 and 2000, plus storefront and office glazing for commercial tenants around the square and along the Powers Ferry corridor.
We are opinionated about two things. First, that the air-leakage rating belongs at the top of a bid rather than buried under a glass package, because a climate with a short winter and a long humid summer punishes leaks in both directions. Second, that the installation matters more than the brand, since a well-installed mid-range window will outperform a premium unit set crooked in an unflashed opening.
There is work we turn down. If your sash are sound and only the sealed units have fogged, we will reglaze instead of replacing and the invoice will be much smaller. If you want impact glazing for hurricane protection in Cobb County, we will explain why that is the wrong purchase here. And if your budget will only stretch to premium frames by cutting the flashing detail, we will tell you to buy the cheaper frame.

Storefront, office and multifamily glazing across Cobb County
Our commercial side covers aluminum storefront, entrance doors, insulated glass replacement and emergency board-up for retail, office and light-industrial tenants in Marietta and the surrounding suburbs.
We work on the two-inch framing that most of this market is built from, whether that means reglazing a sixty-year-old shopfront, swapping tempered lites after a break-in, or specifying thermally broken framing where a bare aluminum frame has been condensing onto the floor inside the entrance every August.
Work is scheduled outside trading hours as standard, and we quote against the tested air infiltration number rather than a description.
- ✓Aluminum storefront reglazing in quarter-inch tempered or one-inch insulated units, matched to your existing framing
- ✓Same-day board-up after a break-in, with dimensions taken off the framing rather than the broken glass
- ✓Thermally broken framing specified where conditioned space is condensing on bare interior aluminum faces
- ✓Air infiltration written to the ASTM E283 test number rather than to a general promise of tightness
- ✓Entrance door repair, closer adjustment, pivot and threshold work on doors that a fire marshal has approved
- ✓Laminated lower panels for tenants who have been broken into more than once at the same address
- ✓Gasket and wet-seal assessment on older storefront, where water reaches the sill flashing before anyone feels a draft
- ✓Night and early-morning scheduling so a ladder is never across a retail doorway during trading hours
Frequently Asked Questions
Do I need a licensed window contractor in Georgia?
Georgia does not license glaziers or window installers as a trade. The state licenses residential and general contractors through the Secretary of State's board, and it separately licenses electrical, plumbing, conditioned air, low-voltage and utility work, but window replacement is not one of the regulated trades. That puts the burden on you.
Ask for a certificate of general liability and workers compensation insurance issued directly by the carrier, ask who is actually doing the install, and ask what the written workmanship warranty covers.
Are triple-pane windows worth it in Marietta?
In our opinion, no. Atlanta's 1991-2020 normals run 2,531 heating degree days, which is a genuinely short heating season, and the extra lite of glass is priced for climates with twice that. You also carry the cost in sash weight, which works the hardware and the balances harder over time. We would rather put the same money into a lower air-leakage rating, better hardware and a properly flashed installation, all of which help in July as well as January.
Will new windows stop pollen getting into my house?
They will reduce it, but they will not stop it, and anyone promising otherwise is overselling. Windows that close against a compression gasket leak far less air than sliding-seal windows, and less air means less of what is in it. Screens do nothing at all here, because insect mesh openings are around a millimeter and oak pollen grains are roughly twenty micrometers. Real reductions come from a MERV 13 filter, sealed return ducts and air sealing at the attic plane.
Insert replacement or full-frame, and how do I know which I need?
An insert sets a new unit inside your existing frame and is faster, cheaper and less disruptive. It also costs you roughly two inches of glass in each direction. On most windows that does not matter. On a bedroom in a 1960s ranch, where the opening is already short, it can drop the clear opening below the twenty-four inch code minimum. It is also the wrong choice over a corroded aluminum frame or where the flashing has failed.
Do I need impact or hurricane windows in Cobb County?
No. Wind-borne debris requirements apply to hurricane-prone coastal regions where design wind speeds reach the code thresholds, and Cobb County sits far inland and well below them. No inspector here will ask for a missile-impact rating. Laminated glass is still a good product in Marietta, but for security, ultraviolet protection and safety glazing rather than for storms. We will quote it on the openings where those reasons apply and standard insulated glass everywhere else.
There is condensation trapped inside my double panes. Is that a whole new window?
Usually not. Fogging tells you the sealed unit's perimeter has let moisture past and the desiccant inside the spacer is spent. Provided the sash still operates, the frame is square and the hardware works, we measure the sight-line dimensions and swap that unit alone for a fraction of a full replacement. It is worth upgrading to a warm-edge spacer and a modern low-E coating while the sash is open. Whole-window replacement for fogging alone is rarely justified.
