“Excellent service from start to finish. The survey was thorough and professional, with honest, evidence-based advice rather than trying to sell unnecessary work. I came away with complete peace of mind.”

“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

Why Winchester homes get damp
Chalk, flint, rivers and a lot of listed buildings. These are the damp problems we see most in Winchester.
Wet ground in the Itchen valley
Homes close to the river and water meadows face higher ground moisture, which old or bridged damp proof courses cannot always stop.
Breathable walls sealed in
Flint, brick and lime walls need to breathe. Cement pointing, gypsum plaster and modern paints trap moisture and cause damp patches.
Condensation in terraces
Victorian terraces in Fulflood and Hyde often have cold solid walls, small rooms and little ventilation, a recipe for black mould.

Your local damp, mould & timber team in Winchester
Winchester is built on chalk in the valley of the River Itchen, and its older buildings use flint, brick and lime. The city centre and streets around the Cathedral have medieval, Georgian and Victorian homes, while Fulflood, Hyde and St Cross have rows of Victorian and Edwardian terraces. Homes near the Itchen and its water meadows sit on wetter ground. Stanmore has inter-war houses, and Badger Farm and Oliver's Battery are more modern. In historic homes the biggest risk is often the wrong repair: cement renders, gypsum plaster and plastic paints that stop solid walls drying out. That is why our surveys follow PCA guidance and we only recommend what your home genuinely needs. If you already know you need damp proofing, see our dedicated Winchester damp proofing page.
