Lime Plastering & Pointing

Traditional materials, applied correctly — the only way to treat a Peak District stone building.

Why Lime Matters

The stone buildings of the Peak District were built to breathe. The lime mortars and plasters used in their original construction allowed moisture to move through the fabric of the building — in and out, naturally, without becoming trapped. It’s why so many of these buildings have stood for centuries in one of England’s most weather-exposed landscapes.

When cement-based mortars and renders are applied to older stone buildings — as has happened widely over the past fifty years — the result is often damp, decay, and long-term damage. Cement is impermeable. It traps moisture, accelerates the deterioration of the stone behind it, and, once removed, often takes the face of the stone with it.

InSpaceConstruction specialise in lime-based plastering, rendering, and pointing — using the correct materials and methods for traditional stone construction. It’s careful, skilled work. And for older buildings, it’s the only approach worth considering.

Lime Plastering & Render

Internal lime plaster and external lime render are the appropriate finish for traditional stone and brick buildings. Breathable, flexible, and able to accommodate the natural movement of old buildings, lime outperforms modern plaster systems in these contexts in every respect that matters.

Lime Pointing & Repointing

The mortar between the stones of a building does an important job — but it’s designed to be the sacrificial element of the wall. Soft lime mortar weathers over time, allowing moisture to escape. When it needs replacing, it should be replaced with the same material.

We assess the existing mortar before any repointing work begins, identifying the appropriate lime mix for the specific building and its exposure. Raking out and repointing is done carefully and thoroughly, ensuring good coverage and the right finish to match the existing character of the wall.

FAQ

How do I know if my building needs repointing?

Signs include mortar that is soft, crumbling, or missing entirely between stones; damp patches on internal walls adjacent to external stonework; and visible erosion of the mortar joint face. We’re happy to carry out a free assessment and advise on the urgency and scope of any work required.

Can I use ordinary cement mortar on a stone building?

We’d strongly advise against it. Cement mortar is harder than the stone in most traditional buildings and will trap moisture, leading to damp and spalling of the stone face. For any building over sixty to seventy years old, lime mortar is almost always the correct choice.

Is lime plastering suitable for modern buildings too?

Lime can be used in modern construction, particularly where a natural or traditional aesthetic is desired, or where breathability is important. We’re happy to discuss the options for any project.
