Heritage Restoration: Respecting Character While Upgrading Performance
Conservation Principles
Minimum intervention, like‑for‑like repairs, and reversibility guide decisions. Documentation preserves provenance and supports approvals.
Material Compatibility
Match vapour permeability and strength: lime mortars with soft brick and sandstone; avoid hard, impermeable repairs that trap salts and moisture.
Common Defects
Salt attack, delamination, failed pointing, corroded fixings and water ingress from poor flashings. Gentle cleaning methods (e.g., nebulous spray) prevent surface loss.
Structural & Aesthetic Balance
Pinning and stitching stabilise cracks; discreet anchors and ties improve safety without altering appearance.
Modern Protection
Breathable water repellents and targeted membranes manage moisture while allowing the building to dry.
Outcome
Sympathetic restoration protects heritage value and extends service life with dignity.
