Water Always Wins — Unless
The Gulf Never Dries
Houston Wood Lives Wet — From Heights Bungalows to Harvey's Flipped Houses
Houston's air comes off the Gulf already loaded, and between the downpours the humidity never gives wood a real chance to dry. That climate hunts two very different victims. In the Heights and Montrose, early-1900s craftsman bungalows carry sills and casings milled in profiles no lumberyard stocks today — irreplaceable woodwork that drinks water at every hairline in the paint. Down in Meyerland and Braeswood, the enemy wears fresh paint: after Harvey put those streets underwater in 2017, a wave of quick flips sanded, caulked and painted over waterlogged frames instead of removing them. That's rot in a costume. A thumbnail test tells the truth — sound wood resists, decayed wood dents like cork no matter how new the paint looks.

Paint that bubbles, lifts or checks along sill edges

Wood a thumbnail sinks into — decay is already inside
-
Freshly-painted flood-zone flips hiding saturated frames

Shaded elevations and sprinkler-sprayed corners rot fastest
The Craft
We Don't Patch Rot — We Remove It and Rebuild the Piece Exactly
The quick fix Houston gets offered everywhere is a tub of wood filler or epoxy troweled into the soft spot and painted smooth. It photographs well and fails fast, because the decay keeps chewing the wood underneath the patch — the same trick those post-Harvey flips pulled, on a smaller scale. Our method is carpentry with a hard rule: probe to the honest boundary of sound wood, cut everything soft out with clean square edges, then fabricate a duplicate of the missing piece from laminated lumber — milled to the original profile, ogees and drip kerfs included — and splice it in until primer and paint erase the seam. The bungalow keeps its hundred-year-old face; the flipped house finally gets the honest repair it was sold as having.

The Process
How Rotten Wood Repair Works in Houston
Probe honestly, price in writing, fabricate exactly, splice cleanly — the sequence that saves good houses.
01/Probe the True Extent
We chase the decay to its real boundary — under paint, into joints, along sill horns — before quoting, because rot hidden under a flip's paint job is bigger than it looks.
02/Price Every Piece in Writing
Window wood from $375, door frames from $475, door sash from $575 — each item its own line on the written sheet before any cutting starts.
03/Fabricate the Exact Copy
The replacement is milled from laminated lumber to the original profile — a precise duplicate of the piece being removed, not a generic board.
04/Splice, Finish & Warranty
Clean joints, seams faired until they vanish, primed, painted and sealed watertight — carried 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 Houston — FAQ
Matching dead profiles is the core of the craft. We take the dimensions off the original piece, mill the duplicate from laminated lumber — coves, ogees, drip kerfs, all of it — and splice it in so the seam disappears under primer and paint. A century-old Heights facade keeps its face; nothing off a big-box shelf touches the house. Window wood rebuilds run from $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.
