Neath property owners come to us when a modern finish has failed. Cement render and gypsum plaster trap moisture inside local rubble stone and slate, and in some of the highest rainfall and wind-driven damp in Britain that shows up as damp patches, salt blooming and rotting timbers. We put it right with breathable lime across West Glamorgan.
Exposure matters as much as material. Neath sits in some of the highest rainfall and wind-driven damp in Britain, which means external work has to shed water and then dry out again quickly. That is exactly what a correctly built lime render does, and exactly what a sealed cement skin prevents.
Around Neath you will find stone longhouses alongside later Victorian chapel-era terraces. Both were built with lime, and both suffer when a modern impermeable finish is applied over the top — the moisture has to go somewhere, and it goes into the masonry and the timbers.
Lime is flexible, breathable and self-healing. On Neath properties built from local rubble stone and slate, it moves with the building instead of cracking away from it, and it protects the masonry rather than the other way round.
Every Neath job begins with diagnosis: identifying where moisture is entering before any plaster goes on. We then remove failed material, prepare the local rubble stone and slate, and build the lime up in coats, allowing each one to cure before the next.
Because thick random rubble walls with earth cores must be able to breathe, Neath throws up a particular set of problems. These are representative examples of how we resolve them in lime.
chapel-era terrace — A commercial chapel-era terrace on a Neath high street within a conservation area. Decayed render and mouldings were reinstated in lime, run in situ to the original profiles, and finished to match neighbouring frontages.
clom-walled smallholding — Eroding masonry faces on a clom-walled smallholding in Neath caused by hard cement pointing. We raked out by hand to the correct depth and repointed in a soft lime mortar matched to the original aggregate and colour of the local rubble stone and slate.
stone longhouse — Blown gypsum plaster and tide marks on the ground floor of a stone longhouse in West Glamorgan. 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.
We do. Neath is one of our core areas and we travel throughout West Glamorgan and the surrounding parts of Wales for lime plastering, lime render, lime pointing and heritage repair.
Yes. We take samples of the surviving mortar or plaster from the local rubble stone and slate first, then match aggregate, colour and texture so the repair blends into the original rather than patching over it.
Every property is different, so we do not publish fixed prices. Cost depends on the substrate, the number of coats, access and whether failed cement has to be removed first. We survey the property in Neath and provide a written, no-obligation quote.
Where damp is caused by trapped moisture in a solid wall — very common in older Neath 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.
Yes. We regularly work on listed and conservation-area properties across West Glamorgan and can supply mix specifications and sample panels for Neath conservation officers where consent is required.
