Groundwater, a faulty drain, surface runoff, a lightwell that cannot drain, a failed earlier repair and condensation can each leave a basement damp. Note when the damp first shows, whether it comes after rain and which walls or floor areas are affected.

BS 8102 is the British Standard for protecting below-ground structures against water. It recognises three approaches: a barrier on the structure, watertight construction and a drained cavity. The right approach depends on the use and the house. Historic England cautions that sealing or tanking can suit modern but not traditional construction.

Internal waterproofing is usually a different planning question from excavating, but lightwells, external changes and listed or conservation status need checking. For a new or extended basement, Camden requires a Basement Impact Assessment, and its Article 4 direction means excavation needs planning permission. The exact address decides which applies.

The programme depends on the survey, any required approvals and material lead times. We confirm availability and written terms after reviewing your Hampstead enquiry, before an appointment is agreed.
