Plymouth property owners come to us when a modern finish has failed. Cement render and gypsum plaster trap moisture inside local limestone and sandstone, 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 Devon.
Damp in Plymouth homes is usually caused by the wrong material rather than a faulty building. Where cement render has been applied over local limestone and sandstone, stripping it back and re-rendering in lime normally resolves the damp within a single drying season.
Around Plymouth 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.
Lime is flexible, breathable and self-healing. On Plymouth properties built from local limestone and sandstone, it moves with the building instead of cracking away from it, and it protects the masonry rather than the other way round.
Every Plymouth job begins with diagnosis: identifying where moisture is entering before any plaster goes on. We then remove failed material, prepare the local limestone and sandstone, 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, Plymouth throws up a particular set of problems. These are representative examples of how we resolve them in lime.
cob and thatch cottage — A cob and thatch cottage in Plymouth 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.
Regency terrace — Peeling modern masonry paint on a Regency terrace in Devon. The impermeable coating was removed, minor render defects were patched in lime, and the elevations were finished in several thin coats of limewash.
stone-built chapel conversion — Eroding masonry faces on a stone-built chapel conversion in Plymouth 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.
Yes. We regularly work on listed and conservation-area properties across Devon and can supply mix specifications and sample panels for Plymouth conservation officers where consent is required.
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 Plymouth and provide a written, no-obligation quote.
We do. Lime repointing is a large part of our Plymouth workload — raking out hard cement pointing and replacing it with a softer, sacrificial lime mortar that protects the masonry face instead of eroding it.
Where damp is caused by trapped moisture in a solid wall — very common in older Plymouth 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.
