Damp, mould & leak services in Eltham

Eltham's housing stock spans Edwardian terraces, interwar LCC cottage estates, 1960s council blocks and modern infill developments. This varied mix creates distinct vulnerability to damp, as older solid-walled properties lack cavity insulation, while post-war flat conversions often suffer from failed pointing, blocked gutters and inadequate ventilation that accelerates mould growth.

Common damp problems in Eltham homes

Rising and Penetrating Damp in Eltham's Interwar Terraces

The substantial interwar terraced streets around Well Hall and Horn Park were built with solid brick construction and basic damp-proof courses that have often deteriorated or bridged over decades. Render applied during later refurbishments can trap moisture against the original brickwork, allowing penetrating damp to migrate inward, causing persistent staining, plaster failure and mould along ground-floor walls and bay window reveals.

Condensation Mould in Post-War Flat Conversions

Converted flats within Eltham's 1950s and 1960s housing blocks, particularly around Coldharbour and Kidbrooke fringes, frequently suffer from condensation-driven mould. Poorly upgraded windows, absent mechanical ventilation and thermal bridging at concrete floor and ceiling junctions create cold surfaces where moisture-laden air readily condenses, producing black mould growth in bedroom corners, bathroom ceilings and around window frames.

Hidden Roof and Gutter Leaks in Shooters Hill Properties

Larger Edwardian and Victorian semi-detached properties on Shooters Hill and along the Falconwood borders often feature complex rooflines with multiple valleys and parapet walls. These junctions are prone to mortar deterioration and lead flashing failure, allowing water ingress that tracks through roof timbers undetected for long periods, only becoming visible as ceiling staining or loft mould after significant structural saturation has already occurred.

What our customers say

★★★★★

Service was excellent! Explained the whole process thoroughly, arrived on time when carrying out the survey. The survey was detailed and exactly what I needed for my insurance. They returned to carry out the treatment the following week. 10/10 would highly recommend.

★★★★★

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

Tip: If a damp patch keeps coming back after redecorating, it is almost always a symptom, not the problem. A survey that finds the source first saves paying for the same repair twice.
