Solid-brick Victorian, Edwardian and interwar homes were built without a cavity or damp course, and they rely on the walls being able to release moisture through the surface. Coat one of those walls in a modern sealed cement or acrylic render and the moisture has nowhere to go — it moves into the brick, carries salts to the face, and starts spalling the masonry behind a coat that still looks fine from the street.
Lime render solves that. It is soft, breathable and sacrificial: it lets vapour pass, and when something has to fail it is the render rather than the brick. It is also more forgiving of the slight movement old buildings have, which is why lime work holds up on walls where cement has crazed.
Heritage work is slower. Lime coats are built up thin and allowed to carbonate, mixes are matched to the original sand colour and grade, and detailing — mouldings, string courses, parapets — is rebuilt rather than simplified. We work to heritage overlay requirements where a permit is involved.
Best suited to
- Solid-brick Victorian, Edwardian and interwar homes
- Properties in heritage overlays and conservation areas
- Walls with existing salt damp or spalling brick
- Restoring mouldings, parapets and rendered detailing
When we'd steer you elsewhere
- Modern cavity-brick or blockwork — acrylic is the better system
- Clients wanting the hardest, most impact-resistant finish
How we do it
The lime & heritage process
Assess the masonry
We check for salt damp, spalling and previous cement patching that is trapping moisture.
Strip incompatible coatings
Old cement render and sealed paint carefully removed without damaging the brick face.
Match the mix
Lime, sand grade and colour matched to surviving original render.
Build up in coats
Thin coats applied and allowed to carbonate between passes, protected from fast drying.
Detailing
Mouldings, bands and parapet detail rebuilt to the original profile.
Common questions
Lime & heritage questions
Why can't I use cement render on a period home?
Solid-brick walls need to breathe. Cement and acrylic seal the surface, so moisture that used to evaporate out gets driven into the brick, bringing salts with it. The render survives; the masonry behind it spalls.
Do you work in heritage overlay areas?
Yes. We work to the finish and profile requirements that come with heritage overlays and can match original mixes and mouldings where the permit calls for like-for-like.
Is lime render less durable?
It is softer by design — that is the point. It wears sacrificially and is easy to repair, whereas a hard render on soft brick transfers the damage to the wall itself.
Other systems we apply
Acrylic Rendering
Pre-coloured, polymer-modified render that flexes with the building instead of fighting it.
Sand & Cement Rendering
The traditional mix, built up in stages, keyed properly and floated dead flat.
Texture Coating & Stucco
Rollcoat, sponge, fine sand and rough cast — matched off an existing wall so the join disappears.
Render Repairs & Recoating
Drummy sections cut out, cracks raked and bridged, patches colour-matched — often a fraction of a full re-render.
Hebel, Foam & Lightweight Cladding Render
Render systems specified for Hebel, polystyrene and lightweight cladding substrates — where the coating is part of the wall system, not a finish on top of it.
