Dunwoody Seal-Rated Window & Door Replacement — Licensed & Insured

Dunwoody sits in DeKalb County with a population of roughly 51,683 at the 2020 census, close enough to Marietta that crews move between the two constantly. Local landmarks and corridors residents know well include Perimeter Mall, the Dunwoody Nature Center.

Local knowledge is not a marketing line here. Dunwoody properties share soil, weather, permit rules and construction eras with the rest of DeKalb County, and a window contractor who works the area weekly already knows what fails locally and what holds up. That is the difference between a bid and an accurate bid.

Call (844) 511-2320 or send the form and we schedule a site visit in Dunwoody, usually within a couple of days. You get a written, itemized free estimate with materials and scope spelled out — no verbal ballpark, no pressure, and no charge whether you hire us or not.

We also serve Chamblee, GA and the rest of Cobb County and northwest metro Atlanta. Everything starts at the Marietta Window Replacement homepage.

Marietta Window Replacement covers the same range of work in Dunwoody that we do in Marietta — nothing is carved out because the address is a few miles up the road:

• 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.
