Looking for lime plastering in Cwmbran? We are traditional lime specialists covering Gwent and the rest of Wales. Our work here ranges from stone longhouses to listed buildings and conservation-area homes, and every mix is chosen for the cob and clom in the west we find behind the existing finish.
Damp in Cwmbran homes is usually caused by the wrong material rather than a faulty building. Where cement render has been applied over cob and clom in the west, stripping it back and re-rendering in lime normally resolves the damp within a single drying season.
The older parts of Cwmbran are dominated by stone longhouses, slate-hung cottages, Victorian chapel-era terraces. 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.
Lime is flexible, breathable and self-healing. On Cwmbran properties built from cob and clom in the west, it moves with the building instead of cracking away from it, and it protects the masonry rather than the other way round.
You get a single point of contact from survey to final coat. We agree the specification for your Cwmbran property in writing, prepare and apply the lime in the correct build-up, and advise on breathable decoration once the work has cured.
Every Cwmbran property is surveyed individually, but these examples show the kind of Gwent buildings and use-cases we are called to most often.
converted stone barn — Peeling modern masonry paint on a converted stone barn in Gwent. The impermeable coating was removed, minor render defects were patched in lime, and the elevations were finished in several thin coats of limewash.
slate-hung cottage — Consented repairs to a listed slate-hung cottage in Gwent. Sample panels were prepared for the conservation officer, mortar analysis informed the mix, and the historic surface was conserved and patched rather than replaced wholesale.
stone longhouse — Blown gypsum plaster and tide marks on the ground floor of a stone longhouse in Gwent. We hacked off the gypsum, applied a haired lime base coat and a lime putty finish, and specified clay paint so the wall could keep drying.
Yes. We regularly work on listed and conservation-area properties across Gwent and can supply mix specifications and sample panels for Cwmbran conservation officers where consent is required.
Yes, but it must be finished with a breathable product such as limewash, clay paint or mineral silicate paint. We advise on suitable finishes for each Cwmbran project so breathability is not lost at the final coat.
External lime work is best carried out between spring and early autumn so it can carbonate before the first frosts. Internal lime plastering in Cwmbran can be done year-round with adequate heating and ventilation.
Where damp is caused by trapped moisture in a solid wall — very common in older Cwmbran properties — replacing cement or gypsum with lime allows the wall to dry out. We always identify the source of moisture during the survey before recommending work.
