RICS Level 3 Structural Survey in Chichester

Chichester's unique housing stock makes a RICS Level 3 Survey particularly valuable for prospective buyers. The city boasts a remarkable concentration of historic properties, with the entire city centre designated as a Conservation Area and numerous Listed Buildings scattered throughout the historic core. Properties within the city walls, particularly those along streets like North Street, South Street, and the areas surrounding the Cathedral, were constructed using traditional methods that differ significantly from modern construction. These buildings often feature solid walls made from flint, brick, or a combination of both, lime mortar pointing, and timber-framed elements that require specialist knowledge to assess accurately.

The geology beneath Chichester presents specific challenges that our surveyors understand intimately. While the chalk formations of the South Downs dominate the northern areas, the city centre and southern areas sit on deposits of Head Deposits and Alluvium, which contain significant clay content. This clay can shrink and swell with moisture changes, potentially causing subsidence or heave issues, particularly for properties with shallow foundations or those affected by tree root growth. Properties in areas like Stockbridge, Whyke, and near the River Lavant floodplain may face additional environmental risks that warrant thorough investigation.

The local climate also plays a role in property condition. Chichester experiences moderate rainfall throughout the year, and properties with compromised gutters, damaged flashings, or inadequate damp proof courses can suffer from penetrating damp or rising damp. Our surveyors frequently identify damp issues in older properties that appear structurally sound but have hidden defects in their moisture protection systems. Similarly, timber elements such as floor joists, roof rafters, and window frames can be affected by wet rot or woodworm, especially in properties where ventilation is poor or maintenance has been neglected.

Beyond the historic core, Chichester has expanded significantly since World War II, with large residential estates built during the post-war period and new developments continuing to the present day. Properties from the 1950s through to the 1980s often feature cavity wall construction, concrete floors, and trussed rafter roofs, each with their own characteristic defects. Our surveyors understand these construction types and can identify the specific issues that commonly affect properties from each era, whether it be corrosion of reinforcement in concrete elements or deterioration of bitumen felt on flat roofs.

Understanding the construction methods used in Chichester properties is essential for identifying potential defects. The city's historic properties, particularly those built before 1900, typically feature solid wall construction without the cavity that modern buildings use for moisture protection. These walls, often constructed from local flint gathered from the surrounding countryside or red/yellow brick, were pointed with lime mortar which allows the building to breathe. When modern cement-based mortars or renders are applied to these historic buildings, moisture can become trapped, leading to damp problems and deterioration of the original fabric. Our surveyors are experienced in assessing these traditional buildings and can identify where inappropriate modern materials may be causing damage.

Properties built between 1919 and 1945 often represent a transitional period in construction methods. Many of these inter-war properties were built with cavity walls, but the cavity was often narrower than modern standards and may not contain effective insulation. Roofs during this period were typically constructed with cut rafters (rather than trusses) and covered with slate or clay tiles. Our inspection process carefully examines these elements, looking for signs of deterioration, past repairs, or structural movement that might indicate underlying issues with the property's integrity.

Post-war construction from 1945 to 1980 dominates many of the residential areas surrounding the historic city centre. These properties were often built quickly to address housing shortages, and while they introduced cavity wall construction as standard, the materials and workmanship varied considerably. Concrete lintels, which can corrode over time, were commonly used, and flat roofs on extensions and garage conversions from this period are frequent sources of leaks. Our detailed survey examines all these elements, providing you with a comprehensive understanding of the property's condition regardless of its age or construction type.

Our surveyors regularly encounter several recurring issues when inspecting properties across Chichester. Damp problems are perhaps the most common defect identified, particularly in the city's older housing stock. Rising damp occurs when moisture from the ground rises through porous brickwork or stonework, often due to a missing or failed damp proof course. Penetrating damp results from water ingress through defective roof coverings, damaged render, or compromised guttering. In properties with solid walls, which are prevalent in the historic centre, traditional plaster and paint can mask underlying damp issues that only become apparent when decorations are disturbed.

Timber defects represent another significant category of problems found in Chichester properties. Wet rot and dry rot affect timber elements throughout properties of all ages, but particularly in older buildings where original timber may have been in place for over a century. Our surveyors pay particular attention to window frames, door frames, floor joists, and roof timbers, looking for signs of fungal decay, insect infestation, or structural weakness. In properties with original timber floors, deterioration can sometimes be extensive but hidden beneath floor coverings. We use probes and moisture meters to assess the extent of any timber decay identified during the inspection.

Structural movement and cracking are also frequently identified in Chichester. While some minor cracking is normal in older properties due to thermal movement and seasonal changes, more significant cracking can indicate foundation problems, particularly in areas with shrink-swell clay. Properties near mature trees, or those with old drainage systems, may be susceptible to ground movement that manifests as diagonal cracking around door and window openings, or bulging walls. Our surveyors assess the nature, extent, and cause of any cracking found, and advise whether further specialist investigation is required. We can also identify issues with lintels, including corrosion of steel lintels that can cause cracking in the masonry above.

Flood risk is a particular concern for certain areas of Chichester that our surveyors take into account. Properties in the Stockbridge area and near the River Lavant can be affected by fluvial flooding during periods of heavy rainfall. Surface water flooding is also a concern in several locations across the city, particularly where drainage systems may be overwhelmed. Our surveyors will note any signs of previous flooding, such as tide marks, warped floorboards, or water staining, and advise on the flood risk specific to the property location. If you are purchasing a property in a flood risk area, we can provide advice on what to look for and any recommended investigations.

• Rising damp and penetrating damp
• Wet rot and dry rot
• Woodworm infestation
• Structural cracking
• Roof tile defects
• Guttering and drainage issues
• Flood damage indicators
• Lintel corrosion

Chichester faces several environmental risks that prospective buyers should be aware of, and our surveyors assess these factors during every inspection. The River Lavant, which flows through the city from the South Downs to Chichester Harbour, is prone to flooding during periods of heavy rainfall. Properties in the Stockbridge area and near the river channel have historically been affected by fluvial flooding, and the Environment Agency maintains flood warnings for these areas. Surface water flooding is also a significant concern, with several areas across the city prone to flash flooding during intense storms.

For properties closer to Chichester Harbour, including areas like Fishbourne, Bosham, and Dell Quay, tidal flooding represents an additional risk factor. While the city centre itself is located at a higher elevation, the surrounding low-lying areas can be affected by coastal flooding during high tides and storm surges. Our surveyors will check the property for any signs of previous flooding and assess the general flood risk based on the location and surrounding topography. We can also advise on what questions to ask about the property's flood history and any flood mitigation measures that may be in place.

The underlying geology of Chichester also presents specific considerations for property buyers. While the chalk geology of the South Downs provides good foundations in the northern areas, the clay deposits in the city centre and southern areas can cause problems for properties with shallow foundations. The shrink-swell potential of these clays means that properties may be affected by ground movement during periods of dry weather or heavy rainfall. Trees located near properties can exacerbate this issue by extracting moisture from the soil, causing the clay to contract and potentially leading to subsidence. Our surveyors carefully assess the foundations, looking for signs of movement or cracking that may indicate ground instability issues.
