What Actually Failed
Why Wooded Lots Rot Window Wood
The hardwoods that sell a Sandy Springs lot keep the house shaded and damp. That's great in July and hard on window wood.
How it happens. Paint keeps the rain out. When it cracks on a sill or the bottom of a sash, water soaks in. Under heavy shade the wood doesn't dry between storms, and a fungus moves in and turns it soft from the inside. Leaves that pile up on sills hold water against the wood, too.
Aluminum-clad windows hide it. The cladding is sealed to the glass with silicone. When that silicone lets go, water gets behind the aluminum and fills the pocket like a bathtub, and the wood sits in it.
Why aluminum-clad wood windows rot where you can't see it Three cross-sections of the bottom of an aluminum-clad wood sash. The aluminum clad covers the outside of the wood and is sealed to the glass with silicone. One: the silicone lets go and rain runs in between the glass and the aluminum. Two: the water collects in the pocket between the aluminum and the wood and fills it up like a bathtub, the same way the desiccant fills in a sealed glass unit; the wood next to it starts to darken. Three: the tub is full, the wood sits in water, never dries and rots, while the aluminum outside still looks perfect.
What we do. We cut the rot out to solid, healthy wood, mill a new piece to the original profile, splice it in, seal it, and fix the spot where the water was getting in. A sash from $375, a sill from $475.

Water Always Wins — Unless
The Canopy Tax
The Trees That Sell Sandy Springs Lots Are the Same Trees That Rot Them
Buyers pay a premium for the mature oaks and hickories shading a Riverside or Huntcliff lot — then discover the fine print. Under that canopy, a north-facing sill can stay damp for days after each of Georgia's fifty annual inches of rain, and along the Chattahoochee corridor the river's morning humidity slows the drying further. The '60s and '70s ranches and split-levels here carry original wood windows — genuinely good lumber, milled in profiles no supplier stocks anymore — but sixty years of wet-dry cycling finds every hairline in the paint film. Water slips into the joint, the shade holds it there, and the sill goes soft from the inside while the surface still photographs fine.

Paint lifting or checking along the sill's outer edge

Wood a thumbnail sinks into — decay already inside

North walls and deep-shade corners always fail first

Irrigation heads soaking trim — the rot owners water themselves
The Craft
We Don't Patch Rot — We Remove It and Rebuild the Piece
The shortcut everyone gets offered is a knife of wood filler pressed into the soft spot and paint rolled over the scar. Twelve months later it's soft again, because the fungus never stopped working under the patch. Our method is the opposite of cosmetic: probe until the true edge of solid, healthy wood is found, saw the decay out with clean square cuts, then mill a replacement piece from laminated lumber that reproduces the original profile — every ogee, bevel and drip kerf — and splice it in so tightly that primer and paint erase the joint. A renovated '70s ranch keeps its original window lines; the repair outlasts the wood it replaced.

The Process
How Rotten Wood Repair Works in Sandy Springs
Probe, price, mill, splice — the discipline that keeps sixty-year-old houses out of the replacement funnel.
01/Probe to Solid, Healthy Wood
We chart the real extent of decay — under paint, through joints, along sill horns — before quoting a single number.
02/Written Price by Piece
Window wood from $375, door wood from $475 — every piece itemized on the written quote before a saw touches the house.
03/Mill & Splice
The replacement is milled from laminated lumber to the original profile and spliced in with joints tight enough to vanish under finish.
04/Finish & Warranty
Sanded, primed, painted and sealed against the weather — with a 5-year written workmanship warranty behind it.

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 Sandy Springs — FAQ
That's precisely the work our bench exists for. Mid-century Sandy Springs windows were milled from lumber and profiles better than anything on a big-box shelf, and a renovation that keeps them keeps the house's face. We cut the decayed sections out to solid, healthy wood, mill exact-profile replacements from laminated stock, and splice them in — from $375 per window piece — so the finished line matches the 1965 original.
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.
