Grays property owners come to us when a modern finish has failed. Cement render and gypsum plaster trap moisture inside clay lump and cob, and in the dry, cold easterly exposure of the eastern counties that shows up as damp patches, salt blooming and rotting timbers. We put it right with breathable lime across Essex.
Exposure matters as much as material. Grays sits in the dry, cold easterly exposure of the eastern counties, 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 Grays you will find timber-framed and pargetted cottages alongside later Georgian merchant houses. 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 Grays properties built from clay lump and cob, it moves with the building instead of cracking away from it, and it protects the masonry rather than the other way round.
Every Grays job begins with diagnosis: identifying where moisture is entering before any plaster goes on. We then remove failed material, prepare the clay lump and cob, and build the lime up in coats, allowing each one to cure before the next.
Because clay lump, flint and timber frame are common and intolerant of cement, Grays throws up a particular set of problems. These are representative examples of how we resolve them in lime.
clay lump cottage — Blown gypsum plaster and tide marks on the ground floor of a clay lump cottage in Essex. 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.
Georgian merchant's house — Eroding masonry faces on a Georgian merchant's house in Grays 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 clay lump and cob.
flint barn conversion — Sagging original ceilings in a flint barn conversion near the centre of Grays. Sound laths were retained and re-keyed, missing sections re-lathed in riven timber, and the ceiling made good with haired lime plaster to match the surviving profile.
Yes — stripping failed cement render and replacing it with a breathable lime render is one of the most common jobs we carry out in Grays. It is usually the fastest way to resolve persistent damp in a solid-wall building.
We do. Lime repointing is a large part of our Grays workload — raking out hard cement pointing and replacing it with a softer, sacrificial lime mortar that protects the masonry face instead of eroding it.
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 Grays project so breathability is not lost at the final coat.
