RICS Level 2 Survey in TW20 (Egham & Englefield Green)

The TW20 postcode covers a diverse range of properties, from period homes in conservation areas to contemporary new-builds. Understanding the local geology and construction methods is essential when assessing these properties. The area is predominantly built on London Clay, which has a moderate to high shrink-swell potential. This means the ground can expand when wet and contract during dry periods, potentially causing subsidence or heave in properties with inadequate foundations. Our inspectors are experienced in identifying the signs of such movement, including cracking patterns and door or window misalignment that may indicate structural concerns.

Many properties in Egham and Englefield Green date from the Victorian and Edwardian periods, meaning they are now well over 100 years old. These older homes often feature solid wall construction, traditional timber sash windows, and original plumbing and electrical systems that may not meet current standards. A RICS Level 2 survey will identify outdated electrics, particularly those installed before the 1980s, which may require complete rewiring, as well as any asbestos-containing materials that were commonly used in properties built before 2000. The area also contains significant post-war housing stock from the 1940s through to the 1970s, which brings its own set of common issues including concrete construction defects and original wiring that may be reaching the end of its lifespan.

The area also includes properties in flood-risk zones, particularly those close to the River Thames and the River Bourne. Surface water flooding can be a concern during heavy rainfall due to the underlying clay soils and urbanisation. Our surveyors will assess the property's vulnerability to flooding and provide recommendations for mitigation measures if necessary. With approximately 100 properties selling in the TW20 area in the past 12 months, the market remains active, making it essential to understand exactly what you are buying before you commit. The average property price in TW20 stands at around £678,000, representing a significant investment that deserves thorough due diligence.

Properties in TW20 are typically constructed from red or yellow stock brick, with some rendered or pebble-dashed finishes particularly in mid-20th century homes. Traditional slate or tile roofs are common on period properties, while newer developments may feature concrete tiles or modern roofing materials. Timber sash windows are a characteristic feature of Victorian and Edwardian homes in the area, many of which have now been upgraded to double glazing though some retain their original single-glazed windows. Our surveyors understand these construction methods and can identify issues specific to each building type found throughout Egham and Englefield Green.

• London Clay subsidence risk
• Victorian and Edwardian construction issues
• Flood risk near waterways
• Outdated electrical systems
• Asbestos in pre-2000 properties
• Roof and timber defects

Our experience surveying properties throughout Egham and Englefield Green has identified several recurring issues that buyers should be aware of. Damp is perhaps the most common problem, particularly in Victorian and Edwardian properties where original damp-proof courses may have failed or were never installed. Rising damp, penetrating damp, and condensation are all frequently identified, especially in properties with inadequate ventilation or that have been modernised without proper consideration for breathability. The solid wall construction common in pre-1919 properties makes them particularly susceptible to damp issues, especially where internal solid floors have been replaced with concrete without proper damp-proofing.

Roof defects are another major finding in TW20 surveys. Older properties often feature traditional slate or tile roofs that may have slipped tiles, degraded felt, or issues with lead flashing. These problems can lead to water penetration and significant damage to internal ceilings and timber structures if not addressed promptly. Our surveyors inspect all accessible roof areas and flag any concerns that require immediate attention or further investigation by a roofing specialist. Properties with large mature trees nearby, such as those often found in the tree-lined streets of Englefield Green, may also have root-related issues affecting foundations or drainage.

Timber defects, including woodworm, dry rot, and wet rot, affect many older properties in the area. These issues are often related to damp problems or poor ventilation in areas such as roof spaces, under-floor areas, and outbuildings. Properties with large trees nearby are particularly susceptible to root-induced subsidence, which is why our surveyors carefully assess the surrounding grounds and any trees within influencing distance of the property's foundations. The proximity to Windsor Great Park and other wooded areas means that trees are a common feature in TW20 gardens, making this assessment particularly important.

Outdated electrical installations are frequently identified in properties built before the 1980s. Original fuse boards with rewireable fuses, lack of earthing, and inadequate socket counts are common issues that our surveyors flag. These electrical systems pose safety risks and will typically require upgrading to meet current regulations before the property can be considered safe. Similarly, lead pipes may still be present in the oldest properties, and original galvanized steel plumbing is common in inter-war housing, both of which may need replacement due to deterioration and water quality concerns.

• Rising and penetrating damp
• Roof tile slippage and felt degradation
• Subsidence from clay soil movement
• Woodworm and timber decay
• Outdated electrical wiring
• Asbestos-containing materials

Your RICS Level 2 survey report uses a clear traffic light system to rate the condition of different elements of the property. Red indicates a serious issue that requires urgent attention, such as significant structural defects or extensive damp penetration. Amber highlights matters that need attention but are not immediately critical, while green indicates that no action is required for that particular element. This system makes it easy to prioritise repairs and budget accordingly. Each element of the property, from the roof and walls to the windows and doors, receives its own rating so you can see exactly where issues lie.

The report also includes a clear summary of the surveyor's overall opinion of the property and advice on any further investigations that may be necessary. If we identify issues such as suspected subsidence, asbestos, or outdated electrical installations, we will recommend that you consult with appropriate specialists before completing your purchase. This advice is designed to protect you from unexpected repair costs and ensure you have full knowledge of the property's condition. For properties in TW20, common recommendations might include a structural engineer's inspection for suspected movement, a damp survey for properties with significant damp issues, or an electrical inspection certificate for properties with outdated wiring.

In TW20, where property prices are currently averaging over £670,000, understanding the true condition of your investment is essential. A RICS Level 2 survey provides you with the information you need to negotiate with the vendor if significant defects are found, either by requesting repairs before completion or by adjusting the purchase price to reflect the cost of necessary works. Given the significant investment involved in purchasing property in this area, the cost of a survey is minimal relative to the potential savings from identifying defects early or negotiating a better deal. Our surveyors have helped hundreds of buyers in Egham and Englefield Green make informed decisions about their property purchases.
