Damp, blown plaster and failing render are common complaints in Cambridge's older housing. Because so much of it is built from soft red brick and exposed to the dry, cold easterly exposure of the eastern counties, the fix is nearly always breathable lime rather than another coat of cement. We deliver that work throughout Cambridgeshire.
Damp in Cambridge homes is usually caused by the wrong material rather than a faulty building. Where cement render has been applied over soft red brick, stripping it back and re-rendering in lime normally resolves the damp within a single drying season.
The older parts of Cambridge are dominated by timber-framed and pargetted cottages, flint churches and barns, Georgian merchant houses. These are solid-wall constructions — there is no cavity, no damp-proof membrane and no vapour barrier — so the wall relies on evaporation through the plaster and render to stay dry.
Using lime in Cambridge is a conservation requirement as often as a technical one. It keeps the property eligible for heritage consent, preserves original detailing, and gives a soft, hand-finished surface no modern board can replicate.
You get a single point of contact from survey to final coat. We agree the specification for your Cambridge property in writing, prepare and apply the lime in the correct build-up, and advise on breathable decoration once the work has cured.
Every Cambridge property is surveyed individually, but these examples show the kind of Cambridgeshire buildings and use-cases we are called to most often.
flint barn conversion — A flint barn conversion in Cambridge where a cement plinth was holding water in the base of the wall. We removed the plinth, lowered adjacent ground levels, and re-rendered the base in a sacrificial lime coat designed to be renewed periodically.
estate farmworker's cottage — Weather-facing walls of an estate farmworker's cottage taking the full force of the dry, cold easterly exposure of the eastern counties. We specified lime putty with local pit sand, often finished with traditional pargetting, built the render up in generous coats and protected the work while it carbonated to avoid shrinkage cracking.
clay lump cottage — Owners of a clay lump cottage in Cambridgeshire wanted warmer rooms without sealing the walls. We installed a woodfibre or cork-lime background and finished in lime plaster, improving comfort while keeping the wall vapour-open.
Yes. We regularly work on listed and conservation-area properties across Cambridgeshire and can supply mix specifications and sample panels for Cambridge conservation officers where consent is required.
We do. Cambridge is one of our core areas and we travel throughout Cambridgeshire and the surrounding parts of East of England for lime plastering, lime render, lime pointing and heritage repair.
Yes — stripping failed cement render and replacing it with a breathable lime render is one of the most common jobs we carry out in Cambridge. It is usually the fastest way to resolve persistent damp in a solid-wall building.
We do. Lime repointing is a large part of our Cambridge workload — raking out hard cement pointing and replacing it with a softer, sacrificial lime mortar that protects the masonry face instead of eroding it.
Lime cures slowly by carbonation. Allow roughly a week per coat as a guide, and longer in the dry, cold easterly exposure of the eastern counties. We protect the work and control drying so the finish cures evenly rather than cracking or dusting.
