Damp, blown plaster and failing render are common complaints in Wrexham's older housing. Because so much of it is built from cob and clom in the west and exposed to some of the highest rainfall and wind-driven damp in Britain, the fix is nearly always breathable lime rather than another coat of cement. We deliver that work throughout Wrexham.
Damp in Wrexham 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 Wrexham 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.
In some of the highest rainfall and wind-driven damp in Britain, an impermeable render is a liability: water gets in at cracks and reveals and then cannot leave. Lime render on a Wrexham wall handles that water, releasing it back out through the surface instead of pushing it deeper into the structure.
You get a single point of contact from survey to final coat. We agree the specification for your Wrexham property in writing, prepare and apply the lime in the correct build-up, and advise on breathable decoration once the work has cured.
Every Wrexham property is surveyed individually, but these examples show the kind of Wrexham buildings and use-cases we are called to most often.
converted stone barn — Blown gypsum plaster and tide marks on the ground floor of a converted stone barn in Wrexham. 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.
chapel-era terrace — Consented repairs to a listed chapel-era terrace in Wrexham. 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.
slate-hung cottage — A slate-hung cottage in Wrexham 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.
Lime cures slowly by carbonation. Allow roughly a week per coat as a guide, and longer in some of the highest rainfall and wind-driven damp in Britain. We protect the work and control drying so the finish cures evenly rather than cracking or dusting.
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 Wrexham 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 Wrexham can be done year-round with adequate heating and ventilation.
