Traditional building care

Why Lime Mortar?

Understanding how compatible mortar can help older stone buildings manage moisture.

A considered approach

Let the wall manage moisture naturally

Many traditional stone buildings were constructed using lime mortar. Unlike some hard cement mixes, suitable lime mortars can allow moisture to move and evaporate through the joints.

In older, softer stonework, overly hard cement pointing may contribute to trapped moisture, flaking stone faces or frost damage. Not every cement joint needs removal: we assess the wall before recommending work.

Why the right mortar matters

Compatibility

Mortar should be suitable for the stone and exposure conditions.

Moisture

Traditional walls often rely on breathable materials to manage moisture.

Appearance

Correct joint profiles and mortar colour help preserve character.

Careful removal

Removing hard mortar can damage stone if undertaken incorrectly.
