Nothing's more annoying than hearing a crash and finding your picture on the floor with a chunk of plaster. Here's why it happens and how to prevent it.
Why Hooks Fail
1. Wrong Hook for the Weight
The problem: Tiny hook, heavy frame.
Standard picture hooks are rated for weight. A single-pin hook might hold 5kg. Your heavy mirror weighs 15kg.
The fix: Check the weight rating. If in doubt, go heavier. A hook rated for 10kg won't mind holding 5kg.
2. Wrong Fixing for the Wall
The problem: Hook for plaster, wall is hollow plasterboard.
The hook may be fine, but it's only as good as what it's attached to.
Wall types:
- Solid plaster on brick: Standard picture hooks work
- Plasterboard on studs: Need plasterboard fixings or hit a stud
- Solid stone: Need masonry fixings
- Crumbly old plaster: Need longer fixings into brick behind
3. Single Point for Large Items
The problem: One hook, large frame.
Big frames swing and pivot on single hooks. This works the fixing back and forth until it fails.
The fix: Two hooks, spaced apart. Distributes weight and prevents swing.
4. Into Soft or Damaged Material
The problem: Wall is crumbly, previously drilled, or just soft.
Old properties in Exeter often have soft lime plaster. Some walls have been drilled so many times they're like Swiss cheese.
Signs:
- Hook goes in too easily
- Plaster crumbles when you drill
- Previous holes visible nearby
5. Insufficient Depth
The problem: Hook isn't deep enough into solid material.
Especially with plasterboard, the hook might be in the wall but not gripping anything structural.
The fix: Longer fixings, proper plugs, or hit a stud.
Matching Hook to Wall
| Wall Type | Light (under 3kg) | Medium (3-10kg) | Heavy (10kg+) |
|---|---|---|---|
| Solid plaster/brick | Single pin hook | Double pin or hardwall | Screw + plug |
| Plasterboard | Self-drive or stud | Plasterboard anchor | Toggle or stud |
| Stone | Hardwall hook | Screw + plug | Heavy masonry fixing |
| Hollow door | Avoid hanging | Small plasterboard hook | Don't |
Types of Picture Hook
Standard Pin Hooks
Best for: Light to medium items on solid walls. How they work: Angled pin driven into plaster/brick. Weight: Single: 5kg. Double/triple: 10kg+.
Hardwall Hooks
Best for: Very hard walls (concrete, stone). How they work: Special hardened pins designed for masonry. Weight: Various sizes, typically 5-30kg.
Self-Adhesive Hooks
Best for: Lightweight items where drilling isn't possible. How they work: Strong adhesive backing (like Command strips). Weight: Usually under 3kg per hook. Caution: Can fail in damp or hot conditions. Can pull paint off when removed.
Plasterboard Fixings
Self-drive: Twist into plasterboard, no pre-drilling. Toggle/anchor: Spread behind the board for grip. Best for: Hollow walls where you can't hit a stud.
Screws with Plugs
Best for: Heavier items, any wall type. How they work: Drill hole, insert plug, screw expands plug. Weight: Depends on plug size - can hold very heavy items.
How to Hang Properly
Light Items (Under 3kg)
- Choose appropriate hook
- Hold item, mark position with pencil
- Measure from wire/bracket to frame top
- Mark hook position
- Insert hook at 45° angle
- Tap in firmly
- Test before walking away
Medium Items (3-10kg)
- Consider two hooks for stability
- Find studs if plasterboard (stud finder or tap test)
- Use appropriate wall plug if drilling
- Check hook rating exceeds weight
- Test by gently pulling down after hanging
Heavy Items (10kg+)
- Use proper wall fixings, not just hooks
- Find studs or use suitable plasterboard anchors
- Two fixings minimum
- Consider professional help
- Never guess with very heavy items
Fixing Failed Holes
The Toothpick/Matchstick Method
For small holes that have pulled out:
- Pack hole with wooden toothpicks or matchsticks
- Add wood glue
- Let dry
- Cut flush
- Re-drill pilot hole if needed
- Insert new fixing
For Larger Damage
- Fill with appropriate filler (Polyfilla for plaster)
- Let dry completely
- Re-drill into fresh filler
- Use slightly larger fixing
For Repeated Failures
Move to a new spot. Some walls are just compromised from previous use.
Pro Tips
Finding the Right Height
For pictures: Centre at eye level (roughly 150cm from floor to centre of artwork).
For above furniture: 15-20cm above the furniture top.
For groups: Lay out on floor first, measure gaps, then mark walls.
The Paper Template Trick
- Trace frame on paper
- Mark fixing points on paper
- Tape paper to wall
- Adjust position easily
- Mark through paper
- Remove paper, install fixings
The Two-Hook Advantage
For anything over 40cm wide:
- Two hooks provide stability
- Less swing means less wall damage
- If one fails, the other catches it
Wire vs D-Rings
Wire: More flexible positioning, slightly harder to level. D-rings: More secure, need accurate hook placement.
When to Get Help
DIY is fine:
- Light to medium items
- Solid walls
- Single items
Consider help for:
- Very heavy mirrors
- Large TVs
- Multiple items requiring layout
- Unusual wall types
