Does Scaffolding Damage Walls? The Facts Explained

Many homeowners worry that scaffolding could leave marks, cracks, or other damage to brickwork or render.
It’s a common concern — especially when planning roof repairs, painting, or extensions where access is tight.

The good news is that properly installed scaffolding should never damage your property.
At B-MAT Scaffolding, we take extensive measures to protect walls, roofs, and garden areas during every installation across London, Essex and Hertfordshire.

Here’s what really causes damage, how we prevent it, and what to look out for when choosing a scaffolding company.

Why People Worry About Wall Damage

Scaffolding looks heavy — and it is. But the weight is evenly distributed through carefully placed base plates, sole boards, and standards.
Problems usually only occur when:

  • The structure is erected too close to delicate surfaces

  • Ties are drilled incorrectly into brickwork or mortar

  • Poor protection is used against rubbing or abrasion

  • Scaffolding is dismantled carelessly

When installed by trained professionals, none of these issues should arise.

How Professional Scaffolders Protect Your Walls

At B-MAT Scaffolding, every setup is designed with building protection in mind:

  1. Correct spacing from the wall – We maintain safe clearance gaps to prevent poles or boards from rubbing.

  2. Use of non-marking ties – Only approved scaffold anchor systems are used, installed in mortar joints wherever possible, not into fragile brick faces.

  3. Protective padding and sheeting – Foam or plastic coverings are added where there’s potential for contact.

  4. Base plates and timber sole boards – These spread the load to prevent sinking or cracking at ground level.

  5. Careful dismantling – Our teams take time to remove ties and fittings cleanly, filling any tie holes neatly if agreed with the client.

These steps eliminate the risk of damage to masonry, render, or paintwork.

What About Rendered or Painted Walls?

Rendered and freshly painted walls are more vulnerable to scuffs or pressure marks.
If you’re having work done on a newly finished surface, tell your scaffolder — we’ll:

  • Increase the distance between scaffold and wall

  • Use foam-covered transoms and non-abrasive protection

  • Avoid fixing through new render wherever possible

For fragile façades (like older Victorian stucco), we can design freestanding scaffolds or cantilever systems that avoid direct tie-ins.

When Wall Damage Can Happen — And How to Avoid It

Occasionally, damage does occur when scaffolds are:

  • Erected by unqualified workers without TG20:21 guidance

  • Built directly against the wall with no clearance

  • Installed on unstable ground causing slight movement

  • Tied in incorrectly, damaging bricks or mortar

To avoid these problems:

  • Always choose a CISRS-qualified scaffolding company

  • Ask for public liability insurance confirmation

  • Request that any wall ties are installed through mortar joints only

What Happens to Tie Holes After Scaffolding?

When scaffold ties are drilled, they leave small round holes (typically 12–14 mm).
A professional scaffolder will:

  • Remove all ties on dismantle

  • Fill each hole neatly with matching mortar or sealant

  • Leave the surface clean and weather-tight

At B-MAT, we routinely patch and tidy all tie points as part of our dismantling process.

Alternative Scaffold Designs for Sensitive Walls

If you have delicate walls, listed buildings, or fragile finishes, we can design access solutions that avoid contact:

  • Cantilever scaffolds projecting from secure anchor points

  • Freestanding towers with counterweights

  • Roof scaffolds using ridge hooks or beams to keep contact off the façade

These options ensure safety and protection for heritage and decorative surfaces alike.
