Damp, blown plaster and failing render are common complaints in Dartford's older housing. Because so much of it is built from flint and knapped flintwork and exposed to the drier but wind-driven weather of the South East coast and Downs, the fix is nearly always breathable lime rather than another coat of cement. We deliver that work throughout Kent.
Exposure matters as much as material. Dartford sits in the drier but wind-driven weather of the South East coast and Downs, 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.
The older parts of Dartford are dominated by timber-framed hall houses, Georgian townhouses, flint-and-brick cottages. These are solid-wall constructions — there is no cavity, no damp-proof membrane and no vapour barrier — so the wall relies on evaporation through the plaster and render to stay dry.
Softness is the point. Traditional Kent walling of flint and knapped flintwork is weaker than modern cement, so a hard mortar concentrates stress and moisture into the masonry face. Lime is deliberately the weaker material, and that is what makes it correct for Dartford's older homes.
You get a single point of contact from survey to final coat. We agree the specification for your Dartford property in writing, prepare and apply the lime in the correct build-up, and advise on breathable decoration once the work has cured.
Every Dartford property is surveyed individually, but these examples show the kind of Kent buildings and use-cases we are called to most often.
timber-framed hall house — A commercial timber-framed hall house on a Dartford 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.
Georgian townhouse — Persistent ground-floor damp in a Georgian townhouse in Dartford 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.
flint-and-brick cottage — Consented repairs to a listed flint-and-brick cottage in Kent. Sample panels were prepared for the conservation officer, mortar analysis informed the mix, and the historic surface was conserved and patched rather than replaced wholesale.
Lime cures slowly by carbonation. Allow roughly a week per coat as a guide, and longer in the drier but wind-driven weather of the South East coast and Downs. We protect the work and control drying so the finish cures evenly rather than cracking or dusting.
Where damp is caused by trapped moisture in a solid wall — very common in older Dartford 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.
External lime work is best carried out between spring and early autumn so it can carbonate before the first frosts. Internal lime plastering in Dartford can be done year-round with adequate heating and ventilation.
Yes. We take samples of the surviving mortar or plaster from the soft red brick first, then match aggregate, colour and texture so the repair blends into the original rather than patching over it.
Yes — stripping failed cement render and replacing it with a breathable lime render is one of the most common jobs we carry out in Dartford. It is usually the fastest way to resolve persistent damp in a solid-wall building.
