RICS Level 2 Survey in DA8 2 Erith

The geological conditions in DA8 2 present specific challenges that our surveyors know to look for. The area sits primarily on London Clay, overlaying Thanet Sands and Chalk. This clay soil has shrink-swell potential, meaning it expands when wet and contracts during dry periods. Properties with shallower foundations, particularly those built before 1980, can experience subsidence or heave movements. Our Level 2 survey includes a visual assessment of the building's structural integrity, checking for signs of movement, cracking, or distortion that may indicate foundation issues. During our inspections, we pay particular attention to properties with mature trees nearby, as tree roots can draw moisture from the clay, accelerating shrink-swell cycles.

Given that approximately 80% of properties in DA8 2 were built before 1980, the prevalence of aging construction presents numerous potential defects. Properties from the 1945-1980 period, which accounts for 40% of the housing stock, often feature original wiring, plumbing, and damp-proof courses that may be deteriorating. Our surveyors inspect electrical consumer units, test a sample of sockets, and note any visible wiring that does not meet current regulations. We also check for signs of damp penetration through walls, particularly in brick properties where mortar joints may have weathered. In our experience, properties along roads like Walnut Tree Road and Colyers Lane frequently show signs of aging damp-proof courses.

The flood risk in DA8 2 deserves particular attention. While the Thames forms the northern boundary of the postcode area and provides some protection through flood defences, properties close to the riverfront face residual tidal flooding risks. More widely, surface water flooding affects low-lying areas where drainage systems become overwhelmed during heavy rainfall. Our survey includes assessment of flood risk factors and notes any signs of previous water damage or damp conditions that might indicate vulnerability. Properties in the lower-lying sections near the river, particularly those on ground floors, receive extra attention during our damp inspections.

The housing composition in DA8 2 reveals why certain defects predominate. With 35% terraced houses and 30% semi-detached properties, the area features substantial mid-20th century construction using brick cavity wall techniques. These properties commonly exhibit penetrating damp where external render has cracked or deteriorated, particularly on north-facing walls that receive less sun exposure. Our surveyors use moisture meters to identify affected areas and assess the extent of any damp penetration. The clay tile roofs common on 1930s and 1940s properties also require careful inspection, as many will be reaching the end of their service life after nearly a century of exposure to British weather.

• Subsidence risk from London Clay
• Damp and condensation issues
• Roof deterioration
• Outdated electrical systems
• Asbestos in pre-2000 properties
• Surface water flood risk

The prevalence of mid-20th century construction in DA8 2 means our surveyors frequently encounter specific defect patterns. Properties built between 1919 and 1945, comprising 25% of the housing stock, often feature older roof coverings including slate and clay tiles that may be reaching the end of their service life. We inspect roof slopes, flashings, gutters, and chimneys for signs of wear, damage, or deterioration. Lead flashings around chimneys are particularly prone to theft or corrosion in older properties, and we note any areas where water ingress may be occurring. Many Victorian and Edwardian properties in the area still have their original clay tiles, which while durable, can suffer from frost damage over decades.

The prevalence of pre-2000 construction means asbestos remains a consideration in DA8 2 properties. Textured ceiling coatings, some types of floor tiles, insulation materials, and certain roofing products may contain asbestos. Our Level 2 survey includes a visual inspection for suspected asbestos-containing materials and provides recommendations for sampling or removal by licensed contractors where necessary. We do not disturb materials but flag areas where asbestos might be present so you can arrange proper testing before any renovation work. In properties built before 1990, we are particularly vigilant for asbestos in Artex coatings and bitumen-based damp-proof courses.

Electrical and plumbing defects feature regularly in our DA8 2 surveys. The properties built during the mid-20th century often have older fuse boards with rewireable fuses rather than modern circuit breakers, and rubber-insulated wiring that may be approaching the end of its safe lifespan. We cannot test behind walls, but we visually assess the consumer unit, exposed wiring, and socket outlets. For plumbing, we look for galvanized steel pipes that may be corroded internally, lead joints, and old tank systems that could be contaminated. These issues are particularly common in the terraced properties along streets like Boundary Road and Lensbury Way.

Damp remains the most frequently identified defect in our DA8 2 surveys. Rising damp affects many properties where the original damp-proof course has failed or was never installed, particularly in solid brick walls. Penetrating damp occurs where external rendering has cracked or where roof details have deteriorated. We use moisture meters to quantify damp levels and can distinguish between rising damp, condensation, and penetrating damp based on patterns and locations. Properties with solid walls are particularly prone to condensation issues, especially in bedrooms and bathrooms where ventilation may be limited. Our reports explain the likely cause and recommend appropriate remediation.
