Water Always Wins — Unless
The Sprinkler Problem
In Katy, the Rot Is Often on Payroll — Your Irrigation System's
The manicured lawns that make the master-plans beautiful come with a hidden tax. Irrigation heads across Cinco Ranch, Grand Lakes and Seven Meadows run on their HOA-tidy schedules, and the ones set a little wrong mist the same window sills and door casings every morning at dawn — then the Gulf's humidity spends the rest of the day making sure nothing dries. Wood that never dries is wood that rots. The second route in is overhead: on the shadeless west elevations, the prairie sun cooks paint film until it checks and hairlines, and every crack becomes a straw feeding water into the builder trim behind it — much of it finger-jointed stock primed once at the factory and never again. The test is simple and honest: press a thumbnail into the suspect spot. Sound wood pushes back. Decayed wood dents like cork, no matter how recent the paint job on top of it.
-
Sprinkler overspray wetting the same sill on a daily schedule
-
Sun-checked paint on west faces funneling water into the trim
-
A thumbnail that sinks in means the fungus is already deep
-
Shaded north corners that stay damp for days after each storm
The Craft
Rot Doesn't Get Patched Here — It Gets Removed and the Piece Rebuilt
Every handyman flyer in the area pitches the same shortcut: press some wood filler or epoxy into the soft spot, paint it smooth by dinner. It photographs beautifully and fails on schedule, because the fungus keeps eating the wood underneath the cosmetic shell — in this humidity, usually within a year or two. Our repair is carpentry with one non-negotiable rule: probe to the honest boundary of sound wood, cut out everything soft with clean square edges, then fabricate a duplicate of the missing piece from laminated lumber — milled to the original profile, bevels and drip kerfs included — and splice it in until primer and paint erase the seam. Laminated stock resists Gulf moisture by its very construction, which makes the rebuild stronger than the builder trim it replaces. And before we leave, the water source gets named — the misaimed sprinkler head, the failed caulk line, the checked paint — so the same corner never calls us twice.

The Process
How Rotten Wood Repair Works in Katy
Honest probing, written pricing, exact fabrication, clean splicing — how good houses stay out of the replacement funnel.
01/Map the Real Damage
Probing runs beneath the paint, through the joints, out along the sill horns — decay always reaches farther than the soft spot you can see.
02/Price by the Piece, in Writing
Each piece gets its own written line — window wood at $375+, door frames at $475+, door sash at $575+ — before any saw starts.
03/Mill the Duplicate
Laminated lumber gets milled into a true copy of the doomed piece's shape — never a generic board forced to fit.
04/Splice, Finish & Warranty
Joints faired invisible, then primer, paint and watertight sealing — the whole rebuild 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 Katy — FAQ
Look at your irrigation coverage. Heads tucked into beds along the foundation routinely throw mist onto the bottom foot of the wall — the same sill, the same casing, every scheduled morning — and Gulf humidity keeps the wood from drying between cycles. That's a rot farm. We rebuild the damaged pieces in real wood from $375, and part of the assessment is flagging exactly which heads need re-aiming so the new wood doesn't inherit the old shower.
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.
