Three Parts, One Warm Room
Where Drafts Come From
Three Small Parts Cause Almost Every Window Draft
Cold air needs a gap, and windows offer exactly three. Weatherstripping flattens with age and stops touching the sash — the biggest culprit. A worn latch stops pulling the sash snug against what seal remains. A tired balancer lets the sash settle a hair low, cracking a sliver at the meeting rail. All three are catalog parts; none is a window problem. The hand test on a cold evening finds them in minutes.
-
Flattened weatherstripping — renewed for $115 per window
-
Latch not clamping — $115 · balancer sag — $175
-
The hand test: a bare palm around the sash edges
-
3-window minimum on strips — stated plainly, no surprises
The Sealing Math
Seal What You Own Before Buying What You Don't Need
The replacement pitch prices a drafty house at $1,000+ per opening. The sealing math reads differently: $115 a window closes the gaps that actually leak, and when the glass itself is the weak point, a Low-E insulated unit swaps into the same frame from $198 — most of a new window's comfort at a tenth of its bill. Professional strips are profile-matched to the sash channel and seat mechanically; the hardware-store foam roll is a one-season apology.

The Process
How Drafty Window Repair Works
A leak hunt with a per-opening price sheet at the end.
01/The Leak Hunt
Every window and exterior door checked by hand — seals, latches and sash height all tell.
02/Per-Opening Sheet
Each leaky opening its own line — strip $115, latch $115, balancer $175 — you pick the rooms.
03/Seal & Snug
Strips seated, latches set to clamp, sashes returned to height — sealing finishes same-day.
04/Re-Check & Warranty
The hand test repeated on every serviced opening — written 5-year 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.

Drafty Windows — FAQ
Often, and there's a free test: run the back of your hand slowly around each window's edges on a cold evening. A thin stream of cool air means seals, latch or sash height — $115–$175 fixes. If the hand test finds nothing, we'll say so honestly instead of selling you sealing you don't need.
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.
