RICS Level 2 Survey in BR4 West Wickham

The bulk of West Wickham's residential streets were developed during the interwar period - the late 1920s through to 1939. Speculatively built by volume developers working outward from London's expanding tram and rail network, these properties were designed to be solid, family-friendly, and affordable. Ninety years on, they remain highly popular. They are also, in many cases, approaching the end of the lifespan of several original components.

Cavity walls became increasingly common in 1930s housebuilding across Greater London, but the wall ties embedded in those cavities were typically galvanised steel - a finish that was expected to last decades but is now, in the worst cases, corroded through. A corroded wall tie loses its structural function entirely, allowing the outer brick leaf to move independently of the inner leaf. The first signs of this are usually horizontal cracking in the mortar joints of the outer leaf, running at the level of the ties. Left unaddressed, the outer leaf can delaminate and eventually bow outward. Our inspectors check for this systematically in every 1930s property they survey in BR4.

The roof coverings of interwar West Wickham properties have typically been replaced at least once in their history, but the roof structure beneath - principal rafters, purlins, ceiling joists - is often original. Woodworm infestation in roof timbers is a common finding in this age of housing, particularly where the roofspace has been poorly ventilated. The insects target softwood structural members; severe infestations can compromise the structural integrity of the roof without any visible external sign. Every inspection includes a full roofspace assessment where access is available.

Lead water supply pipes are another feature of 1930s properties that buyers in BR4 should be aware of. Many properties in this era retain original lead pipework from the street connection to the internal stop valve. While the risk from lead in drinking water is primarily a concern for households with infants, the pipes themselves are also at increased risk of joint failure and pinhole leaks as they age. Our inspectors note visible lead pipework in every report and recommend a plumbing survey where concerns are identified.

The standard RICS Home Survey Level 2 format covers all accessible areas of the property in a thorough visual inspection. Each element is rated using the RICS Traffic Light condition system: Condition 1 (no repair needed), Condition 2 (repair required but not urgent), and Condition 3 (serious defect or further investigation urgently needed). The report is written in plain English and structured so that buyers, solicitors, and mortgage brokers can all extract what they need quickly.

• External inspection: roof coverings assessed from ground level using binoculars, chimneys, flashings, gutters, downpipes, walls including visual check for wall tie cracking, windows, doors, and external drainage
• Roof space: structure including rafters and purlins for woodworm damage, insulation, ventilation, and signs of moisture penetration or previous repair
• Ceilings, walls, and floors: visual inspection with moisture meter readings at regular intervals across all external walls and ground-floor areas
• Internal joinery: doors and windows checked for operation - sticking or binding can indicate structural movement or moisture swelling
• Services: boiler and heating controls, visible electrical consumer unit and wiring, visible plumbing including any lead pipework noted
• Outbuildings and garages: condition assessment included as standard
• Legal and other matters: items for your solicitor to investigate, including planning history for extensions and building regulations compliance

The executive summary at the front of every report gives a prioritised list of the most significant findings. Condition 3 items require immediate action - either specialist investigation, renegotiation, or reconsidering the purchase. Condition 2 items are maintenance issues to budget for. Condition 1 items require nothing from you immediately. This traffic light structure means you can act on the report quickly and decisively.

West Wickham has a small but significant stock of listed buildings, including Grade II listed properties that pre-date the 1930s estate development by centuries. One property known to be on the market in BR4 in recent years is listed as Grade II, dating from the 17th century. Properties of this age and designation require a specialist survey approach - a RICS Level 2 is appropriate for standard interwar housing, but a RICS Level 3 Building Survey is strongly recommended for any listed building.

Listed buildings present specific surveying challenges: original materials such as lime mortar, lath and plaster, and handmade brick behave very differently from modern equivalents. Any alterations made without Listed Building Consent can expose the buyer to a legal liability to reinstate the original fabric at their own cost. Our surveyors note any evidence of inappropriate past alterations and recommend that your solicitor obtains Listed Building Consent history from the local authority as part of due diligence.

Conservation areas, where they apply in West Wickham, impose restrictions on external alterations including window replacement, satellite dish installation, and the removal of trees with a trunk diameter above a certain threshold. If a property you are purchasing is within a conservation area, your solicitor should confirm the extent of the designation and what permitted development rights may have been removed. Our report notes where conservation area status may be relevant based on our knowledge of the local area.
