Damp in Potters Bar Homes
Potters Bar was a small settlement on the edge of Enfield Chase until the Great Northern Railway arrived in 1850 and turned it into a commuter town. Most of its housing went up in the 20th century as the population grew, cavity-walled semis and detached homes, with more added after the war and again once the M25 opened nearby. In those houses the problem is rarely classic rising damp. Far more often it is penetrating damp through bays, render and bridged cavities, or condensation and black mould once newer windows have cut the ventilation right down.
The older Potters Bar runs along the line of the Great North Road. Around Barnet Road, the High Street and Hatfield Road there are Victorian villas and rows of artisan cottages, the Edwardian Royds Estate, and just beyond the town the period homes of South Mimms and Bentley Heath. Solid-walled property like this, especially anything listed or in a conservation area, can suffer genuine rising damp and needs a breathable approach, not the cement renders that trap moisture in old fabric.
Underneath sits heavy London clay, which drains poorly and shifts with the seasons, cracking walls so water tracks in, with alluvial sands and gravels in the lower river valleys where ground damp is more likely. With that range of property and ground, the only reliable starting point is a proper survey.
