Rotten Wood Repair in Cypress, TX
A soft sill on a fifteen-year-old house isn't a verdict on the house. The rotten section gets sawn out to healthy wood, an exact real-lumber duplicate gets milled, and the splice vanishes under paint — from $375. Filler and epoxy over rot? Never — that's the shortcut we exist to undo.

What Actually Failed
Young Houses Rot Too
It surprises people to find rot on a house that's only a few years old. In Cypress it's often the landscaping: sprinklers that hit the windows every morning.
How it happens. Paint is the only protection. When it cracks on the sill or the bottom of the sash, water soaks in. Daily spray keeps the wood wet, and a fungus turns it soft from the inside.
Aluminum-clad windows too. If your windows are clad in aluminum, the cladding is sealed to the glass with silicone. When the silicone lets go, water gets behind it and fills the pocket like a bathtub.
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 on a Timer Beats Wood
The Landscaping Trap
Young Houses Rot Too — When the Sprinklers Water the Windows Every Dawn
Cypress homeowners assume rot is an old-house disease — then find a thumbnail sinking into a sill on a house built in 2010. The culprit is usually standing in the flower bed. HOA-grade irrigation runs before sunrise, and a misaligned head mists the same sill and brickmould every single morning; mulch beds get topped off each spring until the pile bridges the weep gap and holds moisture directly against the trim; and between waterings, Gulf humidity makes sure the fiber never truly dries. Fiber-cement siding on these homes hides the fact that the window frames, door jambs and brickmould behind it are still wood. Decay fungus asks only for sustained moisture, and a Cypress landscape package delivers it on a timer — north walls, fence-shaded corners and bed-facing sills going first.
-
Paint bubbling or checking along the bottom edge of sills
-
Wood a thumbnail dents like cork — decay is already inside
-
Sprinkler-sprayed sills and mulch piled against brickmould
-
Shaded north walls and fence-line corners that never dry
The Craft
Rot Doesn't Get Patched Here — It Gets Removed and the Piece Rebuilt
Every spongy sill in Cypress eventually meets a tub of wood filler — pressed into the mush, sanded, painted, photographed. And underneath, the fungus keeps eating, because the patch never removed the infected wood. We work by a rule with no exceptions: probe until the boundary of genuinely healthy lumber is found, saw out everything soft on clean square lines, then mill a duplicate of the missing section from laminated stock — original profile, slope and drip kerf reproduced — and splice it home until primer and paint hide the joint. Laminated lumber stands up to Gulf moisture by its very construction; the assessment also fingers the water source — that sprinkler head, that mulch pile — so the corner never fails twice; and the written 5-year warranty covers it all. Window wood starts at $375, while a brand-new wood window for that same opening is roughly $2,000 installed.

The Process
How Rotten Wood Repair Works in Cypress
Probe honestly, quote in writing, fabricate exactly, splice cleanly — carpentry, not cosmetics.
01/Probe the True Extent
Decay gets traced to where it truly stops — beneath paint, inside joints, down the sill horns — before we quote, since rot always runs wider than the soft spot you can see.
02/Price Every Piece in Writing
Window pieces from $375, door frame lumber from $475, door sashes from $575 — every item its own written line before a saw touches the house.
03/Mill the Exact Duplicate
The stand-in piece is milled from laminated stock to match the original's profile precisely — a duplicate of what's coming out, never a generic board caulked in.
04/Splice, Finish & Warranty
Tight joints, seams sanded to nothing, then primer, paint and watertight sealing — the whole rebuild under the written 5-year 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 Cypress — FAQ
Check what's happening below that window at 5 a.m. In most young-house cases we trace the rot to a sprinkler head misting the sill on a daily schedule, or a mulch bed topped off each spring until it holds moisture against the brickmould around the clock. Wood age barely matters when water arrives on a timer and Gulf humidity blocks the drying in between. We rebuild the piece in real wood from $375 — and point out exactly which head or bed to fix so the new wood doesn't inherit the problem.
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.
