Specialist Repair and Maintenance of Portland Stone Facades

Published 3 February 2026

Portland Stone Façades

Portland stone is one of Britain’s most significant architectural materials, central to the unified streetscapes of Georgian and Regency London. It’s disciplined use is closely associated with John Nash, particularly along Regent Street, where stone façades imposed architectural coherence across buildings of differing age and structure.

While many façades conceal brickwork or later structural frames, the Portland stone elevations remain the defining historic fabric. Their long-term performance depends on informed repair, compatible materials, and carefully controlled cleaning.

At Pavehall, we provide specialist repair and maintenance of Portland stone façades, combining accredited professional competence with in-house heritage craftsmanship.

In-house repair masons
Our architecturally trained masons carry out like-for-like repairs using traditional lime mortars and in situ stone repair techniques, in line with conservation best practice and SPAB principles.

DOFF cleaning and façade maintenance
We undertake DOFF superheated steam cleaning as part of a carefully specified maintenance strategy, allowing controlled removal of soiling and biological growth without damaging the stone or restricting breathability.
