We provide heritage and artisan finishes to traditional and listed buildings, having worked on projects with CADW, English Heritage and Historic England, as well as private clients.

With 30plus years experience of working with lime mortars, lime plasters, lime renders and lime pointing, along with clay plasters, natural paints, hemp and woodfibre retrofit insulations and insulated lime renders.

We reinstate traditional moisture-open buildings to their original moisture-open state. We also undertake cosmetic repairs, and restore stone and brick facades to their former glory.

Over recent years we have focused our attention on traditional Victorian and Edwardian housing, using natural permeable materials, applying our knowledge and craftsmanship to restore their natural beauty and sympathetically bring them up to modern day living standards.

Traditional properties were originally constructed from natural permeable materials and designed to be moisture-open. Unfortunately cement based pointing and renders, along with synthetic renders are moisture-closed - they stop the building working as it should. Natural moisture-open materials, such as lime and clay, respect the original building, and can create a healthy indoor environment.

Based in Cardiff, we work throughout South Wales and surrounding areas.

Complete overhaul of front facade of an early Victorian property: paint removed, cleaned, stone consolidated and repointed with lime mortar.

Rear abutment wall with cementitious materials causing internal damp. Their removal, followed by repair of stonework and repointing with lime mortar has resulted in a damp free interior.

Impermeable cement mortar sets harder than natural stone, over time this can cause premature erosion and spalling. 

To address this, lime mortar with aggregates to match the stone, is brought flush to the face of the stonework to consolidate the façade and prevent staining from leaching pigments. 

This property had bad damp issues even though it had allegedly received modern damp treatments. We removed all the impermeable cementitious materials, repointed with lime mortar and finished with a lime parge and clay paint which has rectified the damp problem.
