RICS Level 2 Survey in B93 Knowle and Dorridge

Knowle village centre contains some of the oldest housing stock in the B93 postcode, including properties with origins in the Victorian and Edwardian periods. The High Street and the roads surrounding St. John the Baptist Church feature a concentration of period properties that are architecturally significant and individually valued, but that also carry the maintenance demands associated with older construction.

The interwar period brought a substantial expansion of the residential streets between Knowle and Dorridge, producing the detached and semi-detached houses that define much of B93's mid-century character. These properties - typically built in brick with tiled roofs and original timber windows - are popular with buyers who appreciate the larger plot sizes and good internal proportions, but they benefit from careful inspection. Our surveyors frequently identify damp penetration in solid brick walls, deteriorated pointing, failed roof flashings, and the early stages of subsidence cracking in these interwar homes.

Post-war and 1970s-1990s properties, found particularly on the roads closest to Dorridge station, feature cavity wall construction. Our surveyors check for evidence of retrospective cavity wall insulation installation and assess whether any insulation present appears to be performing correctly or creating moisture problems.

Across B93's varied housing stock, our surveyors encounter a consistent set of defects in the properties they inspect. Knowing what is commonly found in Knowle and Dorridge helps buyers understand where the most significant risks lie and what to ask about during the purchase process.

• Damp penetration in solid brick walls of period properties in Knowle village
• Failed lead flashings to chimney stacks and valley gutters in pre-1970 homes
• Diagonal cracking at window openings indicating clay soil shrink-swell movement
• Original single-glazed timber windows with rot in lower rails and sills on interwar properties
• Flat roof extensions past their useful life - common on 1970s and 1980s rear additions
• Asbestos-containing materials in pre-1985 properties: artex ceilings, vinyl floor tiles, pipe lagging
• Outdated electrical consumer units with no RCD protection in older homes
• Tree root penetration into underground drainage runs - elevated risk with dense garden planting
• Poorly maintained guttering causing repeated dampness to upper external walls

Flat roofs deserve specific attention in B93. Many detached and semi-detached homes built in the 1960s and 1970s incorporated flat roof extensions to the rear or garage roof sections constructed with built-up felt. The expected service life of a standard built-up felt flat roof is twenty to twenty-five years. Flat roof covering condition is assessed carefully, with blistering, ponding, or covering deterioration noted, and a condition 3 rating assigned where replacement appears imminent or overdue.

Drainage problems are also more common in B93 than buyers might expect. The area's mature planting - large trees in back gardens, established hedgerows along boundaries - can result in tree root ingress into clay drain pipes, causing blockages or partial collapse. Our survey report flags any evidence of drainage problems observed during the inspection and recommends a CCTV drain survey where concerns are identified.

Our process is designed to cause minimal disruption to your purchase timeline. After you book and pay online, our team contacts the estate agent directly to arrange survey access, handling all the coordination so you can focus on other aspects of the transaction. In B93's competitive market, where good properties attract multiple offers, we work efficiently to arrange inspection as quickly as possible.

On the day of inspection, our RICS-qualified surveyor conducts a thorough assessment lasting two to four hours depending on the size and complexity of the property. They assess the roof from ground level using binoculars to examine ridge tiles, valley gutters, and lead flashings, and access the roof void through the loft hatch where safe. Damp meter readings are taken at regular intervals across all external-facing internal walls, and floor voids are inspected where access allows.

Your completed report is delivered digitally within three to five working days of the inspection. The report uses plain language supported by the condition rating system, with clear explanations of what each rating means in practical terms. Your surveyor is available by telephone after delivery for a detailed conversation about the findings - a call that many of our B93 clients tell us is the clearest part of their entire buying process.
