Westminster's stone facades represent some of London's finest architectural heritage, from Portland stone civic buildings to Bath stone terraces and carved ornamental elevations. Our facade investigation team brings specialist expertise in natural stone deterioration, identifying the mechanisms that cause spalling, erosion, fracturing and biological growth on Westminster's most important facades.
Stone facades in Westminster are subject to a range of deterioration mechanisms: salt crystallisation, frost damage, pollution soiling, sulphate crust formation and structural movement cracking. Each mechanism requires a different remedial approach, making accurate diagnosis essential before any repair work commences.
We provide detailed facade investigations that combine visual assessment, material sampling and laboratory analysis where necessary to identify the specific deterioration mechanisms at work. Our repair specifications are designed to satisfy English Heritage and Westminster conservation requirements.
Systematic visual survey of all external elevations, supplemented by close-up inspection using binoculars, drone photography or rope access where required. We map defects by type, location and severity to establish the overall condition of the facade.
Identification of facade materials, construction methods and original specification through visual assessment, percussion testing and, where necessary, targeted opening-up and laboratory analysis. Understanding the material composition is essential to accurate defect diagnosis.
Systematic investigation of water ingress pathways using moisture profiling, thermal imaging, hose testing and targeted opening-up. We trace water from point of entry to point of appearance, identifying the specific failure that is allowing moisture penetration.
Detailed repair specifications that contractors can price directly. We specify materials, methods, access requirements and performance standards for all remedial works, and can administer repair contracts through to completion and sign-off.

View ServiceA facade investigation is a systematic assessment of an external wall to identify defects, diagnose their causes and recommend remedial action. This typically involves visual survey, percussion testing of render and cladding, moisture profiling, targeted opening-up and, where necessary, material sampling for laboratory analysis.
Fees for facade investigations in Westminster depend on the size and complexity of the building. A focused investigation of a single elevation typically starts from around £1,500, while a comprehensive survey of a large mansion block or multi-storey building may range from £4,000 to £12,000 depending on access requirements and the extent of opening-up.
Yes. Every facade investigation report includes a detailed repair specification that contractors can price directly. We specify materials, methods and performance standards, and can administer repair contracts through to completion if required.
We can typically arrange an initial facade inspection in Westminster within 5 to 10 working days. Where rope access or MEWP hire is required, lead times may be slightly longer depending on access arrangements and third-party availability.
