Shade Holds the Water In
Life Under the Canopy
The Trees That Sold You the Street Are Slowly Eating Your Sills
Dunwoody's tree canopy is the whole point of the place — the oaks and hickories arching over The Branches and Wynterhall are why these streets feel the way they do. They're also why the north side of your house never truly dries. After an afternoon thunderstorm, a sunlit sill sheds its moisture by evening; a shaded one stays damp into the next day, and fungus only needs wood to stay wet. That's why Dunwoody rot has a signature address: the north-facing sills, the corner behind the hollies, the trim the irrigation head mists every morning at six. The original 1970s lumber in these houses is genuinely good wood — but fifty years means fifty seasons of paint seams opening a hair at a time, and every open seam is a straw.
-
Paint that lifts, checks or bubbles along the sill nose
-
A thumbnail sinks in → the decay is already established below
-
Shaded and north-facing elevations always go first — physics, not luck
-
The sprinkler-side sill: watered daily like a garden bed, and it rots like one
The Craft
The Rot Leaves the House. A Milled Copy of the Piece Takes Its Place
There's a fast version of this repair going door to door: push filler into the soft spot, sand, paint, cash the check. Twelve months later the bubble is back, because the fungus never left — it just got a roof. We work the opposite way. Probing tells us where sound wood actually begins; everything decayed comes out to clean, square cuts. Then our bench mills a replacement section from laminated lumber, reproducing the original 1970s profile — the sill nose, the wash slope, the drip kerf underneath — and splices it in with joinery tight enough to vanish under primer and paint. On a Williamsburg-colonial facade where every sill line shows from the street, that invisibility is the standard, not a bonus. And before we leave, we name what fed the rot — the sprinkler arc, the failed caulk joint, the clogged gutter — so the new wood doesn't inherit the old diet.

The Process
How Rotten Wood Repair Works in Dunwoody
Honest probing, per-piece pricing, bench-milled copies — carpentry that saves original houses.
01/Find the True Edge of the Damage
We probe past the paint into joints, sill horns and end grain to map exactly where decay stops and sound wood begins — before any number is quoted.
02/Put Every Piece on Paper
Window wood from $375, door-frame wood from $475, door sash from $575 — each damaged section is its own written line before a saw comes out.
03/Mill the Copy, Make the Splice
The replacement is fabricated in laminated lumber to the original profile and joined in so cleanly the seam disappears under finish.
04/Seal the Wood, Cut Off the Water
Primed on every face, painted, caulked watertight — with the moisture source corrected and a 5-year written workmanship warranty behind it all.

Eugene fabricated both screens and new half double-pane windows for my home. He was professional, dedicated, and experienced. He went above and beyond to ensure the job was done right and in a timely manner. I would highly recommend WowFix for work that meets all expectations!

I had a fantastic experience with WowFix. They repaired my existing windows by cutting out rotted sashes, fashioning new ones on-site, and splicing them in. They look and work absolutely good as new!

WowFix is a great company for repairs on doors and windows. I had two rotten double-door frames that they rebuilt. They communicate well and the pricing was fair.

Rotten Wood Repair in Dunwoody — FAQ
Look up: the back of the house is where the canopy is. Shaded wood can stay damp for a day or more after each storm while sunlit wood dries in hours, and rot fungus only works on wood that stays wet. It's the most common pattern we see in Dunwoody — pristine street side, soft canopy side. Each affected piece is rebuilt from $375, and the shade itself just means we spec the finish and caulk lines for slow-drying exposure.
Before We Arrive
How to Prepare for Your WowFix Window Repair Visit
- 1
Photograph each problem window in daylight
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.
- 2
Note what each window is doing wrong
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.
- 3
Clear about three feet in front of each window
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.
- 4
Find any window brand or paperwork
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.
- 5
Make sure we can reach the windows outside
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.
