Water Always Wins — Unless
A Mill Town's Wood
Roswell Has Been Fighting Wood Rot Since 1839 — Your House Just Joined the War
This town was built by a mill on Vickery Creek, and the wood around Canton Street and the old mill village has been trading punches with Georgia weather for over a century — hand-milled sills and sashes in profiles no lumberyard has stocked in generations. Down toward the Chattahoochee, the '70s and '80s subdivisions fight a different battle: factory-primed builder trim installed with raw end grain, kept permanently damp by sprinkler arcs and the deep shade of a mature canopy that never lets a north wall dry. Fifty-plus inches of annual rain feeds both fronts. The wood is different; the biology is identical — moisture finds an unsealed seam and digests inward until someone cuts it out.
-
Paint lifting or blistering along the sill nose
-
A thumbnail that sinks in — that wood is already lost
-
Shaded, river-facing and north-side wood decays first
-
Sprinkler spray: the rot homeowners water twice a week
The Craft
Preservation-Grade Carpentry: Cut It Out, Mill It Back, Make It Vanish
A tub of wood filler smeared over soft wood is decoration on top of decay — the fungus keeps chewing underneath and the 'repair' pops within a year. Our bench works the way a mill town's should: probe until we hit honestly sound wood, saw the rot out with clean square shoulders, then mill a replacement piece from laminated lumber that reproduces the original profile — every ogee, bevel and drip kerf — and splice it in until primer and paint erase the seam. On a Canton Street sill that means the house keeps its 19th-century face. On a Martins Landing brickmould run it means wood measurably better than what the builder nailed up in 1978. Either way, the water source gets named and fixed too.

The Process
How Rotten Wood Repair Works in Roswell
Probe, quote, mill, splice — honest carpentry that keeps good houses off the replacement treadmill.
01/Probe the True Boundary
We chase the decay to its honest edge — under paint film, into joinery, along sill horns — so the quote covers reality, not the visible tip.
02/Price Every Piece in Writing
Window wood from $375, door wood from $475 — itemized line by line on a written quote before a single cut is made.
03/Mill & Splice
The replacement is milled from laminated lumber to duplicate the original profile, then spliced in with tight, clean joinery until the repair reads as original.
04/Seal, Paint & Warranty
Sanded fair, primed, painted and sealed against the weather — with a written 5-year workmanship warranty behind it.

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 Roswell — FAQ
Reproducing them is the whole discipline. We take the surviving profile — the ogees, the bevels, the drip kerf under the sill nose — and mill the replacement piece to duplicate it exactly, then splice it in so the seam vanishes under primer and paint. Roswell's 19th-century millwork is better wood, better shaped, than anything on a store shelf today; a house from the mill era should keep its face, and this repair lets it.
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.
