“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.”

Areas we cover near Winchester
Our specialists regularly work throughout Winchester and the surrounding neighbourhoods.
Damp challenges in Winchester’s historic homes
With a large conservation area and many listed buildings, Winchester needs a careful, evidence-led approach to damp.
Breathable period walls
Flint, chalk and soft-brick walls built with lime mortar need to breathe. Cement repointing and gypsum plaster trap moisture and cause damp to spread.
River Itchen water table
Properties in the valley bottom, around the Weirs and St Cross, can sit on wetter ground, increasing the risk of rising and below-ground damp.
Cellars & lower floors
Many townhouses have cellars or semi-basements that need a properly designed waterproofing system to become usable, dry space.
Our approach to damp proofing in Winchester
1. Evidence-led survey
Moisture readings, salt analysis and an external inspection of pointing, gutters and ground levels identify the real source of damp.
2. The right treatment
From repointing and masonry water-repellent cream to a chemical DPC or membrane system — chosen to suit the building, not a one-size-fits-all fix.
3. Sympathetic finish
Specialist replastering, with lime-compatible materials on historic walls, leaves a sound, dry and decoratable surface.
