RICS Level 3 Building Survey BN16

Our inspectors conduct a thorough examination of all accessible parts of the property, going far beyond the basic visual inspection of a Level 2 survey. We assess the overall structural integrity of the building, examining walls, floors, ceilings, roofs, and foundations. In BN16, where properties range from historic cottages with solid brick and flint walls to modern new builds at developments like Kingfisher Grange, our surveyors have the local knowledge to identify issues specific to each construction era and style.

The survey includes detailed assessments of damp levels, timber conditions, and roofing. Our inspectors use professional moisture meters and probes to identify rising damp, penetrating damp, and condensation issues that may not be visible to the untrained eye. Given the coastal location of parts of BN16, we pay particular attention to signs of salt ingress and accelerated weathering, which can significantly affect the longevity of building materials in properties near East Preston and Kingston Gorse.

We also evaluate the property's insulation and energy efficiency aspects, highlighting areas where improvements could be made. Our report includes a clear traffic light rating system showing the condition of each element, from critical defects requiring immediate attention to recommendations for future maintenance. Every survey we undertake in BN16 is tailored to reflect the specific characteristics of the local housing stock, whether it's a 1930s semi-detached house in Angmering or a contemporary new-build property.

• Structural walls and foundations
• Roof structure and covering
• Damp and timber condition
• Plumbing and electrical overview
• Insulation and energy efficiency
• Boundaries and external areas

For properties in BN16, a Level 3 survey is particularly valuable given the diverse range of housing stock in the area. With 15% of properties built before 1919 using traditional solid brick or flint construction methods, and 35% constructed between 1945 and 1980, the potential for hidden defects varies significantly across the local housing stock. Our detailed surveys uncover issues that standard mortgage valuation surveys simply won't identify, giving you the information needed to make an informed decision or renegotiate your offer.

The BN16 area presents unique challenges that our inspectors are familiar with. The underlying chalk geology of the South Downs, overlain by superficial deposits including clay-rich Head deposits in some areas, can create shrink-swell risks for foundations. Properties with mature trees or those in areas with significant clay content may be susceptible to subsidence or heave, particularly during extreme weather conditions. Our Level 3 survey specifically investigates these ground conditions and their potential impact on the property's stability.

We also examine properties for flood risk awareness. The River Arun located to the west of BN16, combined with coastal flooding risks in East Preston and surface water flooding during heavy rainfall, means understanding a property's vulnerability to water ingress is crucial. Our surveyors identify historical flood damage, assess drainage systems, and evaluate the potential for future flooding based on the property's specific location and topography.

Our experience surveying properties across BN16 has identified several recurring issues that buyers should be aware of. Damp problems are particularly common in older properties, especially those with inadequate damp-proof courses or poorly maintained external rendering. The traditional brick construction found in many Angmering cottages, combined with the coastal climate, can lead to penetrating damp if external walls are not properly maintained. Our inspectors use specialist equipment to detect damp levels and identify the source of any moisture ingress.

Timber defects, including woodworm infestation and both wet and dry rot, are frequently discovered in properties with poor ventilation or existing damp issues. The timber-framed elements common in older BN16 properties, particularly those built before 1900, can be vulnerable if hidden damp has been present over extended periods. Our surveyors thoroughly examine all accessible timber, including floor joists, roof timbers, and window frames, providing you with a clear picture of any treatment requirements.

Roofing issues rank among the most common defects we find in BN16 surveys. Worn or damaged roof coverings, defective flashings, and blocked gutters can lead to water ingress, particularly given the exposure some properties face from coastal weather conditions. Properties in East Preston and those near the cliff edges may show accelerated weathering of roof materials due to salt-laden winds. Our inspectors assess the entire roof structure, including any visible signs of movement or past repairs.

Foundation movement is another concern we identify in BN16. Properties built on clay-rich soils, particularly those with mature trees nearby, can experience subsidence or heave as the ground swells and shrinks with moisture changes. This is especially relevant during periods of drought or prolonged rainfall. Our surveyors examine walls for cracking patterns, check doors and windows for sticking, and assess the overall stability of the foundation structure.

• Rising and penetrating damp
• Woodworm and rot in timber elements
• Roof tile/slate damage and leaks
• Foundation movement and subsidence
• Rendering and brickwork deterioration
• Coastal weathering and salt ingress

Understanding the construction methods used in BN16 properties helps our inspectors provide more accurate assessments. The area's housing stock reflects its West Sussex coastal plain location, with properties built using materials suited to the local environment. Pre-1919 properties in Angmering and East Preston typically feature solid brick or flint walls with lime mortar, timber floors, and slate or clay tile roofs. These traditional construction methods require specific expertise to assess properly, which our Level 3 survey provides.

The period between 1919 and 1945 saw the introduction of cavity wall construction in the area, though many BN16 properties from this era still retain traditional features. Properties built between 1945 and 1980 account for approximately 35% of the local housing stock, predominantly using standard cavity brick construction with concrete tiled roofs. These post-war homes often represent good value in the BN16 market but can have their own specific issues related to construction quality and material choices of the era.

The newer developments in BN16, including properties at The Hedgerows, Willow Gardens, and Highdown View, represent modern construction methods including timber frame and blockwork techniques. While these newer properties typically require less extensive investigation, a Level 3 survey can still identify any construction defects, snagging issues, or areas where the build quality may not meet expected standards. Our inspectors are familiar with all construction eras found across the BN16 postcode.

Rendered finishes are particularly common throughout BN16, both on newer properties and as a renovation choice on older cottages. While render can improve weather resistance, it can also hide underlying defects in the brickwork or substrate. Our inspectors know how to identify potential problems behind render finishes, particularly where moisture might be trapped and cause deterioration over time.

Certain properties in BN16 particularly benefit from the detailed assessment that a Level 3 survey provides. Pre-1900 properties in Angmering village, with their solid brick and flint walls and original lime mortar pointing, often hide defects that only a thorough investigation can uncover. These historic homes may have undergone various alterations over the decades, and understanding the current structural condition is essential before committing to purchase.

Listed buildings within BN16 require specialist attention due to their historical significance and protected status. Any structural issues or proposed alterations must be assessed with careful consideration of both building regulations and heritage conservation requirements. Our inspectors understand the additional complexities involved with listed properties and can identify issues that might affect future renovation plans or listed building consent applications.

Properties showing visible signs of distress, such as cracking walls, bulging brickwork, or doors and windows that no longer close properly, definitely warrant a Level 3 survey. These symptoms can indicate underlying structural problems that need detailed investigation. Similarly, properties that have been extended or significantly altered over the years may have structural connections that need professional assessment.

New build properties at developments like Kingfisher Grange and Willow Gardens, while generally in good condition, can still benefit from a Level 3 survey to identify snagging issues and any construction defects that may not be apparent to the untrained buyer. Even brand new properties can have issues ranging from minor defects to more serious structural problems that require attention before completion.
