Expert Lime Plastering in Walsall

Condensation and the Sealed Urban Home

Many of the beautiful, solid-walled period properties in Walsall suffer from severe condensation and persistent damp problems. Homeowners often spend thousands on modern chemical damp-proofing treatments that completely fail to solve the issue. The reality is that these solid-walled buildings were never designed to be waterproofed; they were engineered to be vapour permeable. When modern renovations introduce impermeable materials—such as cement-based renders, waterproof tanking slurries, or internal gypsum plaster—the building's ability to 'breathe' is completely blocked. Normal household activities in a modern urban home generate significant airborne moisture, which condenses rapidly on the cold, sealed walls, leading to black mould and peeling decorations. Furthermore, natural ground moisture becomes trapped in the brickwork, accelerating structural decay. Longnor Heritage resolves this by carefully removing the incompatible modern materials and reinstating traditional lime plaster. Lime is highly porous, allowing moisture to pass through it as a vapour and evaporate harmlessly, completely transforming the internal climate of your historic home.

The Authentic Float and Skim Process

Working with traditional lime requires patience, precision, and an in-depth understanding of how historic buildings function. Our highly skilled plasterers do not use modern, gypsum-based shortcuts. We use authentic lime putty, carefully graded sharp sands, and natural animal hair binders to recreate the original plaster matrix of your home. We follow the historic three-coat method to ensure the plaster achieves a full carbonation set. The initial scratch coat provides a strong, flexible key that bonds intimately with the historic brickwork. The subsequent float coat is applied to level the wall while intentionally preserving the charming, uneven character typical of Walsall’s older properties—we never force a sterile, modern flatness onto a historic wall. Finally, a smooth skim coat of fine lime putty is applied, creating a beautiful, breathable finish. Because lime hardens by slowly absorbing carbon dioxide from the air, our team meticulously controls the curing environment, ensuring the plaster dries without shrinking or cracking.
