Heritage Building Restoration and Conservation Specialists
Expert Lime Plastering in Tettenhall
Characterized by the picturesque Tettenhall Green and the historic Tettenhall Rock, this affluent historic village features a stunning array of grand Victorian villas, Georgian properties, and older timber-framed structures. The long-term preservation of these prestigious solid-walled homes requires an uncompromising commitment to traditional building techniques and the exclusive use of highly breathable lime plasters.
Combating Trapped Moisture in Historic Villas
A frequent and heartbreaking sight in the grand older properties of Tettenhall is the gradual deterioration of interior walls, characterized by peeling paint, bubbling plaster, and a cold, damp atmosphere. This decay is rarely due to a failure of the original architecture. Instead, it is almost entirely caused by the misguided application of modern, impermeable materials like gypsum plaster and Portland cement during 20th-century refurbishments. Historic solid masonry was brilliantly engineered to 'breathe,' absorbing environmental moisture and releasing it harmlessly through natural evaporation. When a waterproof layer of gypsum is smeared across a solid brick or stone wall, it traps ground moisture and internal condensation deep inside the structure. The water cannot escape, leading to the rapid decay of the historic lime mortar, rotting of embedded structural timbers, and severe damp penetration. Longnor Heritage specializes in breaking this destructive cycle. We painstakingly remove these incompatible materials and reinstate highly breathable lime plaster, restoring the vital capillary action of the walls and allowing the trapped moisture to safely evaporate.
Mastering the Craft of Traditional Lath and Plaster
Working with traditional lime requires a highly specialized skillset, particularly when restoring the ornate interiors often found in Tettenhall’s period homes. Our master craftsmen do not rely on modern shortcuts; we manage the natural, slow carbonation process of authentic lime putty. For internal partitions and ceilings, we frequently employ traditional lath and plaster techniques. We secure hand-riven oak or chestnut laths and apply a bespoke mix of non-hydraulic lime putty, sharp sand, and natural animal hair. The hair provides critical tensile strength, allowing the plaster to flex seamlessly with the natural seasonal movements of the property’s timber framework without cracking. This scratch coat is followed by a carefully leveled float coat, and finally, a beautifully smooth skim coat that perfectly mimics the soft, undulating aesthetic of genuine historic interiors. This meticulous process ensures a finish that is both structurally sound and aesthetically perfect for a prestige
