Water Always Wins — Unless
Salt Air Never Sleeps
A Few Miles from the Bay, Wood Never Gets a Dry Day
Decay fungus asks for one thing: wood that stays damp. League City delivers it by geography. Air moving in off Galveston Bay and Clear Lake arrives pre-loaded with moisture and a trace of salt — and salt is hygroscopic, so the film it leaves on sills and casings actively pulls water out of the air and holds it against the grain between rains. Add the town's signature shade: the heritage live oaks around League Park and the old center keep the blocks beneath them beautiful and permanently damp, while out in South Shore Harbour and Newport, thirty-plus years of that marine cycle have been chewing at builder trim since the '80s. The oldest houses in the historic district carry sills and casings milled when Galveston County lumber came rough off the wagon — profiles no supplier stocks today, drinking water through every hairline in their paint.

The Craft
Soft Wood Comes Out Entirely — an Exact Copy Goes Back In
There are two ways to treat rot, and only one of them is a repair. The shortcut — troweling filler or epoxy into the soft spot and painting it by dinner — leaves the fungus dining underneath the cosmetic shell, and in bay-side humidity it re-emerges within a couple of seasons, larger. Our way is carpentry under one absolute rule: probe until we find the honest boundary of sound wood, cut away everything soft with clean square edges, then mill a duplicate of the missing piece from laminated lumber — the original's coves, bevels and drip kerfs reproduced — and splice it in until primer and paint erase the joint. A century-old casing by League Park keeps the face it was built with; a 1988 South Shore Harbour sill gets stock that resists marine moisture better than what the builder used. And before the truck leaves, the water's route in — failed caulk, checked paint, a gutter overflowing onto the same corner — gets named so it doesn't happen twice.

The Process
How Rotten Wood Repair Works in League City
Probe to the truth, price on paper, mill the duplicate, splice it clean — how bay-side houses stay out of the replacement funnel.
01/Find the Honest Boundary
We chase the softness to its real edge — under paint, along sill horns, into joints — because marine-fed rot always runs wider than the visible stain suggests.
02/Put Every Piece in Writing
Window pieces start at $375, door-frame wood at $475, door sash at $575 — each rebuild gets its own line on the written sheet before a saw touches the house.
03/Mill the Duplicate
The replacement piece comes off our mill in laminated lumber, shaped to the original profile — a true copy of what's being removed, never a generic board.
04/Splice, Seal & Warranty
Tight joints, seams faired to invisibility, primed, painted and sealed against the bay air — carried by a 5-year written workmanship warranty.

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 League City — FAQ
Matching retired profiles is the heart of this trade. We lift the dimensions off the original piece and mill its duplicate from laminated lumber — coves, ogees, drip kerfs, every line of it — then splice it in so the joint disappears beneath primer and paint. The house keeps the face it has worn for a century; nothing off a big-box shelf gets near it. Window wood rebuilds start at $375 per piece.
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.
