Best Glazing Points for Sash Windows: 2025 Expert Review
DR Joinery
Expert Joiner & Bespoke Fittings Specialist
Re-glazing a sash window involves skill and patience. If the glazing points are too loose, the pane rattles in the wind; if they are driven too tight or hammered incorrectly, the glass cracks instantly. It is a delicate balance.
Many DIY enthusiasts attempt this task using panel pins and a hammer. In my experience, this is a recipe for disaster, especially on older, brittle timber or when using expensive restoration glass. Proper glazing points and the correct push tools are essential for a lasting, professional finish.
In this review, I'll compare three options I've evaluated: a basic budget pack for quick repairs, a professional-grade set with a dedicated tool for precision, and a problem-solving kit designed to save your fingers during larger projects.

Specs vs. The Real World
The Spec: "Rust Resistance (Zinc Coated)"
"Manufacturers claim zinc coating prevents rust indefinitely, making them suitable for all environments."
In York's damp climate, condensation on single glazing is inevitable. Even zinc-coated steel will eventually corrode if left exposed. You must ensure the points are fully encased in linseed oil putty or a high-quality glazing compound to prevent rust bleeding into the paintwork.
The Spec: "Hammer Usage"
"Some listings suggest you can gently hammer these points in."
Never use a hammer directly on glazing points next to glass. The shock alone can crack a pane. Always use a proper push tool or the flat side of a broad chisel to apply steady pressure without impact.
My Top 3 Recommendations
Three options to cover different needs and budgets
Glazing Push Points Steel Glazier's Push Points (Pack of 50)
SISI UK
This is a straightforward pack of 50 steel glazing points. At this price, it represents excellent value for a homeowner who only needs to repair a single pane. They are standard triangular points that sit well in most rebates.
The Good
- Very affordable for small repairs
- Zinc coating provides reasonable corrosion resistance
- Simple, traditional design fits tight rebates
The Bad
- No tool included - requires skill to install without scratching glass
- Can be fiddly to hold in position
Installer Tip:
Since there is no tool included, use a wide woodworking chisel to install these. Place the chisel's flat side against the glass and use it to push the point into the timber. If the wood is very hard (like old oak), pre-ease the grain with a bradawl slightly below where the point will go.

SISI UK / Fletcher Terry
Fletcher Terry is a name we recognise and respect in the trade. This set includes a 'Push Mate' tool, which is critical for controlling force. It allows you to drive the point flat against the glass without the risk of the tool slipping and scratching the pane.
The Good
- Includes the proper push tool for safe installation
- Stainless steel options available for superior rust resistance
- Significant reduction in glass breakage risk
The Bad
- Higher upfront cost if just replacing one pane
- Tool can be stiff to use initially
Installer Tip:
The Push Mate tool is designed to slide along the glass surface. Don't lift the back of the tool up; keep it parallel to the pane. This ensures the point goes in straight and doesn't create a pressure point that could crack the glass later when the timber expands.

Check Price on AmazonGlazier Point Driver Tool with 120 Glazing Push Points & Finger Cots
KWJEIULSOQ
This kit solves the problem of sore fingers and lost points. With 120 points and a dedicated driver handle, it is ideal for larger restoration batches, such as a full bay window refurbishment. The included finger guards are a thoughtful touch for DIYers handling sharp glass.
The Good
- Excellent volume of consumables (120 points)
- Ergonomic handle reduces hand fatigue
- Includes finger protection
The Bad
- The tool is a generic make, potentially less durable than Fletcher models
- Points may be softer metal than premium brands
Installer Tip:
Whilst the finger cots are useful for handling the points, they won't protect you from a shard of glass if a pane breaks. Always wear proper cut-resistant glazing gloves when handling the glass itself, especially when removing old, stubborn putty.
