RICS Level 3 Survey in Costessey

A RICS Level 3 Survey, also known as a Building Survey, is the most comprehensive inspection product available for residential properties in England. While a Level 2 survey provides a general overview suitable for modern properties in good condition, the Level 3 Survey is specifically designed to address the complexities found in older properties, unusual constructions, and homes where you suspect there may be significant defects. In Costessey, where we see properties ranging from pre-1919 solid brick constructions in Old Costessey through to modern cavity-wall developments, the Level 3 Survey provides the detailed assessment necessary to identify issues that might otherwise remain hidden until they become costly problems. The local housing stock represents a fascinating mix of construction eras, from Victorian through to contemporary new builds, each with their own characteristic defect patterns that our experienced surveyors know well.

The inspection covers all accessible areas of the property, including the roof space (where safe access is possible), under-floor voids, the exterior walls, windows, doors, and all internal fixtures and fittings. Our inspectors do not just look at the surface condition; they assess the construction methods, identify materials used, and evaluate how these might perform over time. In properties near the River Wensum or in areas with a history of surface water flooding, our survey will specifically assess any signs of previous water damage or flood resilience measures that may or may not be in place. We examine the interaction between different building elements and how they work together as a system, identifying where deterioration may be occurring even if not yet visible on surfaces.

For properties in Costessey's Conservation Area, particularly those around Old Costessey near Costessey Hall and the Church of St Edmund, a Level 3 Survey is often advisable given the age and historical significance of many buildings. These properties may have non-standard construction methods, previous alterations that require understanding, or specific maintenance requirements that only a detailed survey can uncover. The report provides a clear, jargon-free assessment of all defects found, their cause, and recommended remedial actions, along with an indication of the urgency with which any repairs should be addressed. Properties in conservation areas often have restrictions on future alterations, and understanding these constraints before purchase helps you plan appropriately for any renovation work you may have in mind.

The geology beneath Costessey presents specific considerations for structural assessment. The underlying chalk bedrock, overlain by glacial deposits including sands, gravels, and in some areas clay deposits, can influence foundation performance. Where clay is present, shrink-swell movement can affect foundations and walls, particularly where mature trees are present. Our surveyors are experienced in identifying the signs of such ground movement and can recommend appropriate specialist investigation if needed. This local knowledge is invaluable when assessing properties in areas like the lower-lying parts of Costessey near the river valley, where ground conditions may be more challenging.

• Evaluation of any historic alterations or extensions

Our experience surveying properties throughout Costessey has identified several recurring issues that buyers should be aware of. Damp problems are particularly common in older properties, including rising damp, penetrating damp from defective roof coverings or damaged pointing, and condensation issues in properties with inadequate ventilation. The solid brick construction typical of pre-1919 properties in Costessey lacks the cavity wall construction found in newer homes, making them more susceptible to damp penetration, especially where the external brickwork has suffered from frost damage or where render has failed. Properties with solid walls may benefit from specific damp-proofing considerations, and our survey will identify where remedial action may be required.

Timber defects are another significant finding in Costessey's older housing stock. Woodworm activity can be present in structural timbers, particularly in properties with a history of roof or floor repairs. Wet rot and dry rot can affect timber elements where moisture has been allowed to penetrate, whether from defective plumbing, leaking roofs, or inadequate ventilation. Our inspectors will thoroughly examine all accessible timber elements, including roof trusses, ceiling joists, floor joists, and window frames, to identify any active timber defects that may require treatment or repair. In some older properties, previous timber repairs may have been carried out using inappropriate methods that we can identify and comment on.

The local geology presents specific considerations for properties in certain parts of Costessey. The underlying clay deposits in some areas can cause foundation movement through shrink-swell activity, particularly where trees are present near the property. This ground movement can manifest as cracking in walls, doors and windows sticking, or uneven floors. Our survey will specifically look for signs of such movement and may recommend a geotechnical investigation or monitoring if concerns are identified. In properties built on or near the floodplains of the River Wensum, we also assess the history of flooding and any existing flood mitigation measures that may or may not be adequate. Surface water flooding is also a concern in some areas of Costessey, particularly during periods of heavy rainfall.

Roofing issues are frequently identified in our Costessey surveys, particularly in properties with older tiled roofs. Slipped or broken tiles, damaged or missing ridge tiles, and deteriorated flashing around chimneys and roof windows all allow water penetration that can lead to internal damage. Our inspectors will access the roof where safe to do so and assess the overall condition, identifying any repairs that may be required urgently. For properties with flat or low-pitched roofs, we pay particular attention to the condition of the covering and any signs of ponding or membrane failure that could lead to leaks.

Understanding the construction of your Costessey property is key to appreciating why a Level 3 Survey can be particularly valuable. According to census data, the housing stock in Costessey comprises approximately 35.8% detached properties, 32.7% semi-detached, 17.5% terraced, and 13.5% flats or maisonettes. This mix reflects both the historical development of the village and the significant new build activity in recent decades. The diversity of property types means that each survey requires a tailored approach, with our surveyors understanding the typical defects associated with different construction methods and ages of property.

Pre-1919 properties in Costessey, particularly those in the Old Costessey area, typically feature solid brick walls with lime-based mortars that allow the building to breathe. These properties often have traditional timber-framed roofs with slate or clay tiles, and timber floor structures that may include hidden voids perfect for inspecting structural timbers. The solid brick construction, while durable, can be more susceptible to damp penetration than modern cavity wall construction, and our surveyors know exactly what to look for when assessing these historic properties.

Properties built between 1919 and 1980 generally feature cavity wall construction, where two leaves of brickwork are separated by an air gap. This construction method provides better thermal performance and moisture resistance than solid walls. However, these properties may have specific issues related to their era, such as the use of systemic calcium chloride in concrete that can cause staining, or the presence of asbestos-containing materials in Artex coatings, floor tiles, or pipe insulation. Our inspectors are trained to identify these period-specific issues.

Modern properties built since the 1980s, including those in new developments like Round House Park, East Hills Meadow, and Clover Gardens on Longdell Road, typically feature modern cavity wall construction with brick and blockwork. While these properties are generally in good condition, they are not immune to defects. Our Level 3 Survey can identify any construction defects, issues with building control compliance, or problems that may have emerged in the relatively short period since construction. New build properties may also have warranty defects that become apparent only after careful inspection.
