Properties in Lewes
Lewes is the county town of East Sussex, a historic market town built on a steep hillside above the River Ouse. The housing stock is exceptionally varied and includes medieval timber-framed buildings, Georgian townhouses, Victorian terraces, and flint-built cottages. Many properties in the High Street and the narrow twittens are Grade I or II listed. The Cliffe area and South Street contain rows of Georgian and Victorian houses, while the surrounding streets have a mix of period and more modern housing.
Common Damp Issues in Lewes
Lewes's position on the River Ouse means that flooding and water damage are significant concerns for properties in the lower-lying areas — the severe floods of 2000 and more recently have affected many homes in the Cliffe area and along the riverbank. We provide flood damage repair and preventive waterproofing for at-risk properties.
Rising damp is extremely common in the older properties, many of which pre-date the concept of a damp-proof course. The flint-built walls found throughout Lewes are particularly vulnerable to penetrating damp when lime mortar joints deteriorate. Timber decay — both wet rot and dry rot — is a significant issue in the oldest buildings, where structural timbers may have been absorbing moisture for decades or centuries.
Our Experience in Lewes
Lewes has a rich architectural heritage and many of its buildings are protected. We have extensive experience working on listed buildings and properties within the Lewes conservation areas, using appropriate traditional materials and methods. The town's famous Bonfire Night celebrations, castle, and independent shops draw visitors year-round, and maintaining the historic building stock is important to both residents and the wider community.

We had a terrible condensation and mould problem in our Victorian terrace. The team identified the ventilation issues, installed a PIV unit and new extractor fans, and the mould has not returned since. Really knowledgeable and professional throughout.
Had a full damp survey done before purchasing a period property. The report was incredibly detailed and saved us from a very costly mistake — the property had serious dry rot that the vendor's surveyor had missed entirely. Worth every penny.
Brighton Damp Proofers treated woodworm in our roof timbers and replaced two decayed joists in the ground floor. The work was done efficiently with minimal disruption. The 30-year guarantee gives us real peace of mind.
