Our Stonemasonry Services in Helensburgh

Lime Pointing

Our lime pointing specialists replace hard, cracked, or cement-based mortar with breathable lime mortar that works in harmony with your sandstone. This prevents dampness, salt crystallisation, and frost damage, common issues in Helensburgh’s coastal climate.

Benefits include:

• Improved breathability and moisture control
• Reduced internal damp and salt damage
• Enhanced appearance and structural integrity

Perfect for: sandstone houses, chimneys, boundary walls, and period facades.

Sandstone Restoration

We carefully restore and replace damaged sandstone to match the original profile and colour of your property. Each new stone is hand dressed by our skilled masons, ensuring a seamless finish that enhances the character of your home.

Our work includes:

• Indents and patch repairs
• Replacement of lintels, sills, mullions, and cornices
• Ashlar and string course restoration

Stone Repairs & Conservation

For minor damage, we use lime based stone repair mortars and crack stitch repair to stabilise the existing stonework without full replacement. This approach is cost effective and retains as much of the historic fabric as possible.

Common repairs include:

• Crack stitching and joint consolidation
• Re-bedding loose stones
• Pinning and dowelling fractured sections

Masonry Cleaning

Our low-pressure steam cleaning in Helensburgh safely removes dirt, revealing the actual colour and character of the sandstone without damaging the surface.

Chimney, Coping & Parapet Repairs

We also repair and rebuild chimneys, copes, and parapets that have been affected by wind exposure or water ingress. Using lime based mortars and correct lead detailing, we make sure these exposed areas remain safe and weatherproof.

Frequently Asked Questions

What’s better, lime or cement pointing?

Lime mortar is flexible and breathable, allowing stone to release moisture naturally. Cement traps moisture, which can lead to cracking and damage over time.

Can you match the colour of my existing stonework?

We source the best available matching stone for your property.

Do you work on listed buildings?

Yes, we have extensive experience with heritage and listed properties, following conservation best practices.

Is cleaning safe for sandstone?

Yes, cleaning will remove years of build up and surface dirt. However, it will not remove black carbon staining or alter the historic fabric.
