RICS Level 3 Survey Alkham

Alkham’s housing stock brings a few particular headaches, which is why a Level 3 Survey is so useful here. Around 30% of properties pre-date 1919, and a fair number sit within the Conservation Area, so many homes benefit from the deeper look that only a full structural survey gives. Add the village’s position in the Alkham Valley, plus chalk geology and patches of clay-rich superficial deposits, and some properties can be vulnerable to ground movement, especially where mature trees are nearby.

We often inspect houses built with traditional solid wall construction, usually with lime mortar instead of modern cement. Those older methods need specialist knowledge to judge properly. Our checks cover the things we expect to find in older Kentish properties, from original timber frames to the condition of damp-proof courses, or the complete absence of them, and traditional roofs finished in clay tiles or natural slate.

Flood risk in parts of the Alkham Valley also matters. Homes close to the Alkham Stream, or in spots affected by surface water flooding, may have a history of water damage that has left its mark on foundations, damp proofing and structural integrity. We look closely for signs of earlier flooding, such as water marks, damaged plasterwork and deterioration in ground-floor timbers.

• Properties in the Alkham Conservation Area
• Grade II listed buildings needing detailed inspection
• Homes near the Alkham Stream with flood risk
• Properties on clay-rich ground near mature trees

From surveying properties across Alkham, we have seen a few recurring problems that buyers should keep in mind. Damp is especially common in older homes, particularly those with solid walls that lack proper damp-proof courses or have been insulated badly. Rising damp and penetrating damp can affect walls, floors and timbers, and that can lead to plasterwork deterioration as well as possible health concerns.

Timber defects turn up regularly in Alkham’s older housing stock too. Woodworm infestation and rot can affect structural timbers, including floor joists, roof rafters and load-bearing elements. Poor ventilation or persistent damp often sits behind these problems. Our surveyors check all accessible timber elements carefully and record any signs of active infestation or decay.

Roofs with traditional tile or slate coverings are another common source of findings. Wear and tear, slipped tiles, damaged lead flashing and defective gutters all appear often in our reports for the area. With so much of Alkham’s housing stock being old, many roofs will already have gone beyond their expected lifespan and need regular maintenance or replacement.

• Rising damp and penetrating damp in solid wall properties
• Woodworm and wet rot in structural timbers
• Defective rainwater goods and gutter systems
• Slipped or damaged roof tiles and slates
• Issues with traditional lime mortar pointing
• Surface water flooding affecting ground floor elements

The geology of the Alkham Valley brings its own issues, which our surveyors factor in when assessing properties. The area is mainly underlain by chalk bedrock from the North Downs, and that usually means stable ground conditions. Even so, superficial deposits including Head deposits, made up of clay, silt, sand and gravel, can sit above the chalk, especially in lower-lying parts of the valley. Homes built on these clay-rich deposits may be vulnerable to shrink-swell movement, particularly where mature trees draw moisture from the soil.

Flood risk is a real consideration for homes in the Alkham Valley. The Alkham Stream runs through the village, and although river flooding risk is generally low, surface water flooding during heavy rainfall events is a known concern. Properties in valley locations, and those with poor drainage, may see water pooling and later damage to foundations and ground-floor elements. Our surveyors look for signs of earlier flooding and assess how well the drainage systems work.

Alkham’s closeness to major transport links, including the A2, M20, Port of Dover and Eurotunnel, makes it appealing to commuters. Demand has pushed property prices up, with detached properties averaging £700,000. That premium, driven by the rural setting and strong connections, means a thorough survey is a sensible step to protect such a substantial purchase.
