What Is Window Glazing (And Why It’s Failing)
4
Glazing is the putty that:
- Holds the glass in place
- Seals out water and air
- Protects the wood frame
Over time, it dries out and fails.
👉 Once it starts cracking and falling out, everything else follows:
- Water intrusion
- Wood damage
- Paint failure
- Loose glass
⚠️ The Hidden Issue: Lead Paint
If your home or building was built before 1978…
👉 There’s a very good chance lead paint is present.
That means:
- You can’t just scrape Old Window Glazing Repair and go
- You need containment
- You need proper cleanup
- You need trained (and ideally certified) workers
This is where DIY turns risky—fast.

- Plastic laid below work areas
- Full containment of debris
