Why is lime mortar better than cement for old buildings?

Lime mortar is softer and more breathable than cement, allowing moisture to escape through the joints rather than being forced through the stone. This prevents the dampness, frost damage, and stone decay that cement repointing causes in traditional buildings.

How long does lime mortar repointing last?

Properly applied lime mortar repointing can last 80-100 years or more, similar to the original mortar. This longevity depends on the quality of materials, correct application technique, and appropriate aftercare during the initial curing period.

Can lime mortar be used for structural repairs?

Yes. Hydraulic lime mortars can be used for structural repairs including crack filling, bed joint reinforcement, and rebuilding. The choice of lime type depends on the structural requirements and exposure conditions.

How much does lime mortar repointing cost?

Lime mortar repointing typically costs £80-£150 per square metre in Penzance, depending on the masonry type, joint style, access requirements, and mortar specification. We provide detailed quotations after inspection.

Do I need lime mortar repointing for my listed building?

Almost certainly. Listed building consent conditions typically require the use of lime mortar for any repointing work. Using cement mortar on a listed building without consent is a criminal offence. We can advise on the correct mortar specification for your property.

Q: Why do properties in Penzance experience subsidence?

Penzance has specific ground conditions that contribute to subsidence risk. Penzance and the surrounding Penwith peninsula have a rich mining history, with tin and copper workings extending beneath many residential areas. The town's exposed position means buildings face severe weather, while abandoned mine shafts and adits present ongoing ground stability risks. These local factors mean that subsidence investigation and repair in Penzance requires specialists who understand the area's unique geology and building traditions.
