Rotted Sill, Caught in Time
Decay cut out completely and rebuilt in real wood — no filler, no new window.
The double-hungs your Dunwoody colonial was built with are pushing fifty — and it shows in windows that drop shut, jam halfway, or won't lock. Every symptom is a worn part with a printed price: hardware from $115, balances $175. The original window stays; only the tired parts leave.

Many of Dunwoody's original double-hungs are still hanging after half a century, running on worn-out balances. Tap what your window is doing:
What is your window doing?
Diagnosis
The sealed glass unit
The seal around the edge of the glass opened. Moisture got in and filled the drying beads inside the unit like a bathtub. When the tub overflowed, the fog showed up on the inside of the glass, where no cloth can reach.
We swap just the glass unit in your frame, from $198.
How foggy glass gets fixed →Diagnosis
The pivot shoe, a small plastic part
Hidden springs in the sides of the frame hold the sash up through a plastic pivot shoe. Over the years the plastic dries out and its hook breaks off, so nothing holds the sash anymore. Sometimes a sash that was forced snaps its metal pivot pin instead.
New balances and shoes, $175 a window.
Why windows won't stay up →Diagnosis
The bottom of the sash and the sill
Paint is the only armor wood has. Once it cracks, rain soaks into the flat parts at the bottom and never dries, and a fungus turns the wood soft from the inside. The top of the window stays solid.
We cut out the rot and splice in new wood: a sash from $375, a sill from $475.
How rot starts and how we fix it →Diagnosis
The crank operator, a small gearbox
On a casement window, a little gearbox under the sash turns the handle into motion. Its teeth strip with age, or all at once when a stuck window gets cranked hard. The handle spins free and the window stays put.
A new operator bolts in, $275.
More on broken cranks →Diagnosis
The weatherstripping
The soft strip around the sash flattens with age and stops touching it, so air walks right through the gap. A worn latch that no longer pulls the sash tight makes it worse.
New weatherstripping, $115 a window (3 windows minimum).
How we seal drafty windows →Diagnosis
Just the glass
A stray ball, a stone from the mower, a hard knock. The glass broke; the frame and the sash didn't.
New glass in your frame: a single pane from $164, a double-pane unit from $198.
Glass repair, every type →Diagnosis
The screen: its mesh, or its frame
Sun slowly breaks down the coating on the mesh until the strands snap instead of flexing, and it tears. Press it gently with your thumb: springy mesh only needs a wash, stiff papery mesh is done. Then look at the frame.

Diagnosis
The sash lock
The lock on the middle rail pulls the two sashes together. When it wears out, or the sash settles a little low, the two halves no longer meet and the window won't lock.
A new lock, $115.
Window hardware we replace →A window that slams shut is the classic one here. It's the part that holds the sash, not the window. Keep the original and replace the part.

Not sure what it is?
The brick colonials of Dunwoody Club Estates, Redfield and The Branches went up in the 1970s and early '80s with honest wood double-hung windows — and a remarkable number of those originals are still in their openings today. What's quit isn't the window; it's the mechanism hidden inside the jamb. Spiral and block-and-tackle balances lose their spring tension after four or five decades, and the older rope-and-pulley sashes fray their cords — so the sash you lift comes crashing down the moment you let go. Homeowners call it the guillotine window, and around here it's practically a rite of passage. Add settled foundations that pull lock keepers out of line and paint layers that glue sashes into their tracks, and you get a house full of windows that technically work and practically don't.
Replacement crews look at a fifty-year-old wood window and see a tear-out ticket at $1,000+ per opening. We see a frame of real lumber — tighter grain than anything sold today — that needs maybe $175 worth of new balances and a $115 lock to run like it did under the first owner. Because the mechanism is a commodity part matched by measurement, not by brand, we service the originals no matter who milled them. And when the visit turns up something outside the hardware bench — fog trapped in a retrofit glass unit, a cracked pane, a soft sill on the shady side — it moves to the right specialist line on the same written sheet: sealed units from $198, glass from $198, wood rebuilds from $475. One scheduled visit, one quote, and the house keeps the windows it was designed around.
Every stuck, slamming, drafty window on one list — cleared in a single scheduled visit.
Falls shut, sticks halfway, won't lock, whistles — plain descriptions are all dispatch needs to map your house to catalog lines and load the truck right.
Dunwoody sits on our scheduled metro-Atlanta routes, so you get a real appointment date from dispatch — not a window of maybes.
Balances swapped, cords re-rigged, locks re-aligned, tracks freed and weatherstrip renewed — each item at its printed price on one written quote.
You watch every repaired sash glide, hold and lock before we leave, and the work carries a 5-year written workmanship warranty.

No stock footage, no actors — this is one of our actual jobs. Watch a rotted, fogged-out window brought back to flawless, like-new condition.
Snap a clear photo of every foggy, cracked or stuck window in natural light. Morning light shows fog between the panes best and lets us quote faster — often before we arrive.
Jot down the symptom per window — fog between the glass, won't open or stay up, draft, cracked pane, or rotted frame. It tells us whether it's a glass-only swap (from $198) or hardware/wood work.
Move furniture, blinds and décor back roughly three feet so our crew can measure and work safely. It keeps the visit quick and your things out of the way.
If you have the original window brand, a sticker in the frame, or install paperwork, set it aside. It's not required, but it helps us match glass and parts on the first trip.
Unlock gates, secure pets, and clear the exterior path to the windows. Most glass-unit work is done from both sides, so outside access keeps everything one visit.
Decay cut out completely and rebuilt in real wood — no filler, no new window.
We fabricate an exact-profile piece from laminated lumber and splice it in.
New glass built to the window's exact size — frame and trim untouched.
The pane is the part that failed — so the pane is the part we replace.
A failed seal, not a failed window: the sealed unit is swapped, the frame stays.
Rotted bottom rebuilt on-site — a fraction of the ~$10,000 a new door runs.
