How to Troubleshoot Decorative Mirror Installation Issues at Home

Quick answer (read this first)

• Check for loose fittings.
• Verify wall type for proper anchoring.
• Ensure mirror is level.
• Re-secure mounting hardware.

Safety first

• Wear gloves and eye protection.
• Have a helper for large mirrors.
• Do not overtighten screws.
• Avoid working near electrical wires.
• Clear the area below the mirror.

Tools you may need

• Screwdriver set
• Drill (if re-drilling)
• Level
• Pencil
• Measuring tape
• Wall plugs/anchors (appropriate for wall type)
• Stud finder (if applicable)
• Cleaning cloth

Step-by-step

Step 1

Safely Assess the Issue: Carefully observe the mirror for any visible cracks, wobbling, or misalignment. Have a helper steady it if there’s any instability.

Step 2

Inspect Mounting Hardware: Examine all screws, clips, hooks, or Z-bars. Confirm they are fully engaged and not loose on both the wall and the mirror.

Step 3

Confirm Wall Type and Anchors: Identify your wall material (e.g., brick, concrete, plasterboard) and verify if the installed wall plugs or anchors are correctly rated for the mirror’s weight and wall type.

Step 4

Check and Adjust Level: Place a spirit level across the top and sides of the mirror. Mark any necessary adjustments to mounting points for perfect horizontal and vertical alignment.

Step 5

Remove (If Needed) and Re-mount: If significant adjustment or anchor replacement is required, carefully remove the mirror with assistance. Clean the wall and mirror backing, then re-position and secure, tightening all connections firmly but avoid overtightening.

Step 6

Final Stability Check: Once re-secured, gently push on the mirror’s corners and edges to confirm it is stable, flush against the wall, and free from any movement or wobble.

Common mistakes

• Using wrong wall anchors for wall type.
• Not using a level for alignment.
• Overtightening screws, leading to damage.
• Attempting to lift heavy mirrors alone.
• Ignoring minor wobbles, which can worsen.

When to call a professional

• Mirror is cracked or severely damaged.
• You suspect structural damage to the wall.
• Mounting hardware is stripped or broken beyond repair.
• The mirror is too heavy or large to handle safely alone.
• You are unsure about electrical wiring behind the wall.
