Weymouth property owners come to us when a modern finish has failed. Cement render and gypsum plaster trap moisture inside granite and killas rubble, and in the wet, wind-driven rain typical of the South West that shows up as damp patches, salt blooming and rotting timbers. We put it right with breathable lime across Dorset.
Damp in Weymouth homes is usually caused by the wrong material rather than a faulty building. Where cement render has been applied over granite and killas rubble, stripping it back and re-rendering in lime normally resolves the damp within a single drying season.
Around Weymouth you will find cob and thatch cottages alongside later Georgian and Regency 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.
In the wet, wind-driven rain typical of the South West, an impermeable render is a liability: water gets in at cracks and reveals and then cannot leave. Lime render on a Weymouth wall handles that water, releasing it back out through the surface instead of pushing it deeper into the structure.
Every Weymouth job begins with diagnosis: identifying where moisture is entering before any plaster goes on. We then remove failed material, prepare the granite and killas rubble, and build the lime up in coats, allowing each one to cure before the next.
Because cob, rubble stone and granite make breathability non-negotiable, Weymouth throws up a particular set of problems. These are representative examples of how we resolve them in lime.
cob and thatch cottage — Persistent ground-floor damp in a cob and thatch cottage in Weymouth previously treated with injected DPC and waterproof render. Once the real moisture path was identified, the walls were replastered in lime and the damp resolved without chemical treatment.
Regency terrace — Eroding masonry faces on a Regency terrace in Weymouth 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 cob.
harbourside fisherman's cottage — Blown gypsum plaster and tide marks on the ground floor of a harbourside fisherman's cottage in Dorset. 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 — stripping failed cement render and replacing it with a breathable lime render is one of the most common jobs we carry out in Weymouth. It is usually the fastest way to resolve persistent damp in a solid-wall building.
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 Weymouth and provide a written, no-obligation quote.
Where damp is caused by trapped moisture in a solid wall — very common in older Weymouth 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, 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 Weymouth project so breathability is not lost at the final coat.
