The Method
Cut, Mill, Splice, Seal — Why Our Rot Repairs Don't Come Back
Rot is a living process: fungus eating damp wood outward from a water source. Smearing filler over it entombs the disease — the handyman fix that fails within a year. Our method removes the disease entirely: probe to the sound-wood boundary, cut the decay out with clean square edges, mill a replacement piece from laminated lumber copied to the original profile — every slope and drip edge — splice it in, then seal the water path that started it all. Under paint the repair disappears; under weather it outlasts the original.
-
Probe first — the boundary decides everything
-
Clean square cuts — no ragged gouging, no guesswork
-
Laminated lumber — engineered to shrug off water
-
The water source corrected, not just the symptom
Where Epoxy Fits
Epoxy Is a Tool, Not a Method — Here's the Honest Line
Structural epoxy consolidation earns its keep on small, early, honestly-probed spots — hardening sound-adjacent fibers where cutting would take more than it saves. That's the whole legitimate territory. Deep rot, the kind inspectors flag and sills crumble from, gets the full cut-and-splice. On-site, the probe decides which case yours is; wishful thinking doesn't get a vote, and neither does the invoice.
-
Early shallow spots — epoxy consolidation, honestly judged
-
Established rot — cut out and rebuilt, no shortcuts
-
Windows from $375 · door frames from $475 · door sash $575
-
Versus ~$2,000 for one new wood window

The Process
How Rotten Wood Repair Works
The same four moves on every rot job, every era of house.
01/Probe to Sound Wood
The decay mapped to its true edges — you see exactly what's spent and what survives.
02/Written Price by Piece
Each section its own line: sills, sashes, jambs, thresholds — before a saw moves.
03/Cut, Mill, Splice
Decay out with clean edges; laminated replacements milled to profile and spliced in.
04/Seal & Warranty
Primed, painted, water path corrected — written 5-year warranty on the rebuild.
Transparent Pricing
How Much Does Rotten Wood Repair Cost?

- For scale — a new wood window runs ~$2,000

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.

No stock footage, no actors — this is one of our actual jobs. Watch a rotted, fogged-out window brought back to flawless, like-new glass.
Rotten Wood Repair — FAQ
The screwdriver test: press gently. Sound wood pushes back; rot gives like cork. Bubbling or flaking paint, dark stains after rain and a dull knock are the early postcards. If it gives — call while the soft spot is measured in inches, not feet.
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.
