Why Repointing Matters in Romsey
Romsey is a market town with a striking mix of building ages and styles. The town centre contains Georgian townhouses and Victorian terraces with soft lime mortar pointing that dates back a century or more. Further out, 1990s and 2000s brick-built estates in areas like Cupernham and Woodley are now reaching the age where mortar begins to deteriorate — cracking, receding, or pulling away from the brickwork. In both cases, leaving failing joints unattended leads to water ingress, internal damp, and over time, structural damage that costs considerably more to fix than a timely repoint.
Lime Mortar vs Cement: The Critical Choice for Romsey's Older Properties
One of the most common and costly mistakes in repointing older Romsey properties is using modern cement mortar on brickwork that was originally built with lime. Pre-1920s construction — which covers much of the town's historic core — used a soft, flexible lime mortar designed to accommodate the natural movement of old buildings. When hard OPC (ordinary Portland cement) mortar is applied over this type of masonry, it becomes stronger than the surrounding bricks. The result is that instead of the mortar joints absorbing movement, the bricks themselves crack. Remedying this kind of damage is expensive and can compromise the wall's structural integrity.
Moore & Son assess the original mortar specification before recommending any mix. For properties built before the 1920s, we use an appropriate natural hydraulic lime (NHL) mortar matched in colour and consistency to the original pointing. For post-war and modern homes across SO51, a suitable cement-based mix delivers a durable, weathertight finish.
Signs Your Romsey Property Needs Repointing
Deteriorating mortar is not always obvious from ground level. After heavy rain, look for dark staining along the joints — water tracking into the wall face rather than running off it cleanly. Press a finger into the joints on a dry day; mortar that crumbles or flexes needs replacing. Visible gaps between brick and joint, along with internal damp patches on external walls, are more advanced warning signs. Frost damage in winter can accelerate the problem significantly, with repeated freeze-thaw cycles dislodging weakened mortar and widening cracks.
Our Repointing Process
We rake out deteriorated mortar to a minimum depth of 15mm using angle grinders and hand chisels. Hammers alone are avoided as they risk loosening adjacent bricks. Joints are vacuumed clean before mortar is applied in two stages: a backing coat for depth and adhesion, then a finishing coat tooled to the correct profile. For period lime work, we follow SPAB guidance on mix ratios and curing times. For modern properties, we use a weather-resistant cement mix in a colour matched to the existing pointing.
Most two-storey Romsey properties can be completed in one to two days. Scaffolding requirements depend on the property, and we advise on this during our free site visit. If you're concerned about the condition of the pointing on your home, contact Moore & Son to arrange a no-obligation assessment.
