Port Talbot property owners come to us when a modern finish has failed. Cement render and gypsum plaster trap moisture inside cob and clom in the west, 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.
Port Talbot's building stock reflects the history of Wales, and thick random rubble walls with earth cores must be able to breathe. Applying gypsum or cement to these walls traps moisture; lime lets it evaporate freely, protecting the fabric of the building for decades.
Around Port Talbot 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.
Solid-wall buildings in Port Talbot were designed to absorb and release moisture. Lime keeps that cycle working; cement seals it in. That single difference explains why so many West Glamorgan homes develop damp after a modern refurbishment.
Every Port Talbot job begins with diagnosis: identifying where moisture is entering before any plaster goes on. We then remove failed material, prepare the cob and clom in the west, 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, Port Talbot throws up a particular set of problems. These are representative examples of how we resolve them in lime.
converted stone barn — Blown gypsum plaster and tide marks on the ground floor of a converted stone barn 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.
chapel-era terrace — Eroding masonry faces on a chapel-era terrace in Port Talbot 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.
clom-walled smallholding — Peeling modern masonry paint on a clom-walled smallholding in West Glamorgan. The impermeable coating was removed, minor render defects were patched in lime, and the elevations were finished in several thin coats of limewash.
Yes. We regularly work on listed and conservation-area properties across West Glamorgan and can supply mix specifications and sample panels for Port Talbot conservation officers where consent is required.
Where damp is caused by trapped moisture in a solid wall — very common in older Port Talbot 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 — stripping failed cement render and replacing it with a breathable lime render is one of the most common jobs we carry out in Port Talbot. It is usually the fastest way to resolve persistent damp in a solid-wall building.
