Tackling Damp: Tim’s Common-Sense Approach to Healthier Homes

At this week’s meeting, Tim from Butler Proctor shared his expertise on one of the most misunderstood issues in property maintenance—damp. With over 55 years of experience, Tim explained that many damp problems in older buildings stem from well-intentioned but misguided modern interventions, such as replacing breathable lime plaster with impermeable cement-based materials. These changes can trap moisture, leading to condensation and damage.

Tim highlighted that lifestyle changes also play a key role. Modern homes are built airtight, which, without adequate ventilation, can lead to moisture build-up. Everyday activities—like cooking, showering, and even drying clothes indoors—can produce up to 20 litres of moisture per day in a household. He emphasised that rather than immediately turning to costly damp-proofing treatments, we should first look holistically at how a home is used and maintained. Simple steps such as improving ventilation, unblocking chimneys, and using breathable materials can make a significant difference.

Tim also touched on the historical context of damp courses, explaining that they were originally introduced in the Victorian era when streets were awash with waste. However, modern surveys often rely on outdated assumptions, with some valuers mistaking condensation for rising damp. This can lead to unnecessary and costly work, which banks often demand before approving mortgages.

The takeaway? Addressing damp is about common sense: managing moisture, maintaining the property, and respecting its original design.
