Why Leeds homes get damp
Leeds has one of the largest stocks of Victorian back-to-back and through terraces in the country, plus dense student rentals around Headingley and Hyde Park. Solid brick walls stay cold, and busy shared houses produce a lot of moisture from cooking, showers and drying clothes indoors.
Rising damp and chemical injection in Leeds
True rising damp shows as a tide mark up to about a metre high, salts on the plaster and skirting that rots from behind. Where the damp course has failed, we inject a chemical damp-proof course at the base of the wall, then replaster with a salt-resistant render where the old plaster is contaminated. Where the cause is a bridged damp course — raised paths, rendered plinths or debris in cavities — we fix that first so you are not paying for injection you don't need.
Penetrating damp treatments
Damp patches that grow after rain come from water getting through the wall: porous brickwork, leaking gutters and downpipes, or failed window seals. We trace the entry point, fix the source and treat the wall — including breathable water-repellent masonry creams that stop rain soaking in while letting the wall dry out. Where cracked or blown render is the problem and the wall needs re-rendering, we recommend the team at Leeds Renderers and we treat the damp once the render is sound.
Condensation that looks like damp
Most damp calls in Leeds are condensation. Black mould on cold walls, wet windows and damp behind wardrobes point to humidity, which ventilation fixes rather than damp proofing. PIV units & ventilation →
