Water Always Wins — Unless
Fifty Inches a Year
Marietta Rot Has Two Favorite Victims — and Your House Is One of Them
Metro Atlanta takes roughly fifty inches of rain a year, and the humidity between storms never lets the wood truly dry. That climate feeds on two kinds of Marietta houses. Around the Square and Whitlock, century-old sills and sashes carry profiles nobody mills anymore — beautiful wood that soaks at every failed paint line. Out in the '80s and '90s East Cobb subdivisions it's the opposite problem: finger-jointed builder trim that was primed once at the factory and never stood a chance under a Georgia sprinkler system. Different wood, same physics — water finds a seam, shade keeps it wet, and the rot works inward season by season.
-
Paint bubbling or flaking at the sill's front edge
-
Wood that dents under a thumbnail — already past saving
-
North walls and shaded corners under mature pines rot first
-
Sprinkler overspray: the self-inflicted rot nobody suspects
The Craft
Filler Over Rot Is the Handyman Lie — We Cut It Out and Rebuild
The cheap fix you'll be offered is a trowel of wood filler over the soft spot and a coat of paint over the filler. It fails within a year, because the decay keeps eating underneath. Our repair is carpentry, not cosmetics: we probe to the honest boundary of sound wood, cut the rot out with clean square edges, fabricate a replacement piece from laminated lumber milled to the original profile — ogees, bevels, drip kerfs and all — and splice it in until the seam disappears under primer and paint. The historic houses keep their faces. The subdivision trim comes back stronger than the builder ever made it.

The Process
How Rotten Wood Repair Works in Marietta
Probe, price, fabricate, splice — the sequence that keeps good houses out of the replacement funnel.
01/Probe to Sound Wood
We map the honest boundary of the decay — behind paint, into joints, along the sill horns — before promising anything.
02/Written Price by Piece
Window wood from $375, door wood from $475 — each piece on its own line of the written quote before the saw comes out.
03/Fabricate & Splice
The replacement piece is milled from laminated lumber to the original profile, spliced in with clean joints, and fitted until the seam vanishes.
04/Finish & Warranty
Sanded, primed, painted, sealed watertight — and backed by a 5-year written workmanship warranty.

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 Marietta — FAQ
That's the entire craft: the replacement piece is milled to copy the original — ogees, bevels, drip kerfs — then spliced in and finished until the repair disappears under paint. Older Marietta wood usually deserves saving; the profiles are better than anything in a big-box aisle, and matching them is exactly what our bench does.
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.
