Northampton property owners come to us when a modern finish has failed. Cement render and gypsum plaster trap moisture inside ironstone and limestone rubble, and in the moderate but frost-prone Midlands winters that shows up as damp patches, salt blooming and rotting timbers. We put it right with breathable lime across Northamptonshire.
Northampton's building stock reflects the history of East Midlands, and banded limestone and ironstone walling needs a soft, sacrificial mortar. Applying gypsum or cement to these walls traps moisture; lime lets it evaporate freely, protecting the fabric of the building for decades.
Around Northampton you will find limestone cottages alongside later Victorian brick 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 Northampton were designed to absorb and release moisture. Lime keeps that cycle working; cement seals it in. That single difference explains why so many Northamptonshire homes develop damp after a modern refurbishment.
Every Northampton job begins with diagnosis: identifying where moisture is entering before any plaster goes on. We then remove failed material, prepare the ironstone and limestone rubble, and build the lime up in coats, allowing each one to cure before the next.
Because banded limestone and ironstone walling needs a soft, sacrificial mortar, Northampton throws up a particular set of problems. These are representative examples of how we resolve them in lime.
mud-and-stud cottage — A mud-and-stud cottage being brought back into use outside Northampton. Because banded limestone and ironstone walling needs a soft, sacrificial mortar, we plastered internally in lime over a breathable insulating background and left the external stonework repointed rather than sealed.
converted stone barn — Sagging original ceilings in a converted stone barn near the centre of Northampton. 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.
ironstone farmhouse — Cracked and cement-patched panels on an ironstone farmhouse in Northamptonshire. Failed infill was cut out, laths and staves renewed where rotten, and the panels made good in haired lime so the frame can move without splitting the finish.
Yes — stripping failed cement render and replacing it with a breathable lime render is one of the most common jobs we carry out in Northampton. 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 Northampton and provide a written, no-obligation quote.
External lime work is best carried out between spring and early autumn so it can carbonate before the first frosts. Internal lime plastering in Northampton can be done year-round with adequate heating and ventilation.

Yes. We take samples of the surviving mortar or plaster from the ironstone and limestone rubble first, then match aggregate, colour and texture so the repair blends into the original rather than patching over it.
