What Actually Failed
What's Actually Rotting: the Window Sill
When someone in Gastonia says "rotted sill," it's worth knowing which sill they mean. A window sill is the sloped piece of wood under the window, outside. A sill plate is framing on top of the foundation. We rebuild window sills. Sill plates are framing work for a contractor. Here's where the window sill sits:
Why a window sill rots. It catches every drop that runs down the glass. While the paint holds, water runs off. When the paint cracks, rain soaks in and the nearly flat sill stays wet longer than anything else on the window. The fungus moves in and turns the wood soft from the inside.
How to check yours. Press a screwdriver into the sill, near the ends. Solid, healthy wood stops it. Rot lets it sink in. Peeling or bubbling paint on the sill is usually the first sign.
What we do. Cut the rot out to solid wood, mill a new piece to the original profile, splice it in, prime it, and close the gap that was letting water in. A sill from $475, a sash from $375. The rest of the window stays.

The Right Trade for the Rot
Sills, Answered Fully
Window Sills vs Sill Plates — Which One Is Rotting on You?
Gastonia asks us about 'rotted sill plates', and the honest answer starts with a distinction. The sill under your WINDOW — the sloped wood shelf that sheds rain — is our trade: cut out and rebuilt from $475. The structural SILL PLATE — the framing timber sitting on your foundation — is a framing contractor's job, and we'll tell you so on sight rather than practice on your house. Most of what Gastonia calls sill rot is the first kind, and it fixes beautifully.

Mill-Town Wood
Houses Built to Be Repaired Deserve Repairs Built to Last
The mill villages built Gastonia out of solid, straight-grained lumber and simple, serviceable joinery — houses designed for a century of maintenance, not a 30-year teardown cycle. Our rebuild honors the design: decay cut to solid, healthy wood, a laminated piece milled to the original profile, spliced, sealed, painted. The filler-and-paint shortcut breaks that century contract; we don't.
-
Profiles milled to match the original

Laminated lumber — no appetite for water

“I had a good experience with WowFix when they came out to provide an estimate for my front door. He was very nice, took the time to discuss the issue with me, and provided an estimate without pressuring me to make a decision on the spot. He was understanding and gave me time to think things over before moving forward. I appreciate his time and professionalism!”

“Wanted to wait until I had the door painted. Eugene did a fantastic job tearing out the entire frame down to the brick mold due to wood rot. He basically rebuilt the entire thing along with the wood rot on the door itself. He does work some unconventional hours but the craftsmanship was worth it.”

“Excellent service. Eugene was super helpful, and found out the replacement rollers for our 20 year old patio glass door ( the original company has discontinued the product). The door works fine. He also helped me in adjust the screen door.”

Rotten Wood Repair in Gastonia — FAQ
Depends which sill: the wood shelf under your window — that's us, cut out and rebuilt from $475. The structural timber sitting on your foundation — that's a framing contractor, and we'll say so at the door instead of improvising. One free look sorts it; most calls turn out to be the window kind.
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.
