Damp and flood-recovery expertise for Leatherhead and the Mole valley.

Leatherhead sits on the River Mole, and any assessment of damp in the low-lying parts of the town has to consider the river. Properties in the flood plain may have experienced past inundation, and even where they have not, ground moisture levels close to the Mole are appreciably higher than on the surrounding downland.

Away from the river, Leatherhead has a substantial period core, extensive inter-war and post-war suburban development and a growing number of modern apartment schemes. We survey all of these, and where a property has a flood history we pay particular attention to sub-floor voids, wall bases and any hidden materials that never fully dried after the event.

Local property types

The old town retains timber-framed, brick and flint buildings with solid walls and shallow foundations. Surrounding roads are largely 20th-century semis and detached houses, with larger properties towards Fetcham and Ashtead. Riverside and low-lying areas include properties with suspended timber ground floors highly sensitive to sub-floor moisture, and some with historic flood-resilience measures.

Local knowledge

Common damp problems in Leatherhead

Flood plain residual moisture

Properties affected by past flooding often retain moisture in sub-floor voids, wall cavities and insulation that was never professionally dried.

Sub-floor damp and timber decay

High ground moisture combined with blocked airbricks produces wet rot in joist ends and persistent musty odours.

Solid-wall damp in the old town

Historic buildings suffer where hard cement render and modern plaster prevent walls from evaporating moisture naturally.

Condensation in converted commercial buildings

Office-to-residential conversions frequently have poor ventilation provision and high humidity in the first years of occupation.

Practical local advice

If your property has flooded before, have the sub-floor void inspected even if everything looks fine at floor level.
Keep airbricks well clear of the ground and consider periscope vents where levels are high.
Use lime plaster and breathable paints on old town properties — they tolerate moisture rather than trapping it.
