RICS Level 3 Building Survey in Oswestry

Our RICS Level 3 Building Survey provides a thorough inspection of all accessible areas of the property. We examine the walls, roof, floors, foundations, and structural elements, producing a detailed report that identifies defects, explains their causes, and recommends appropriate remedial action. The survey goes far beyond the basic visual inspection of a Level 2 report, providing comprehensive analysis of construction materials, build quality, and potential future maintenance requirements.

For Oswestry properties, this level of detail is particularly valuable given the range of construction types found in the area. From the 25.4% of homes built pre-1919 using solid brick or stone walls with lime mortar, through the cavity brick construction popular from 1900-1945, to the post-war developments and more recent new builds, our inspectors have the expertise to assess each property type accurately. The report includes specific guidance on the property's construction method and how this affects its performance and maintenance needs.

The Level 3 survey is strongly recommended for properties in Oswestry's Conservation Area, which covers the historic town centre and includes numerous listed buildings. These properties often have unique construction features and may require specialist knowledge of traditional building methods. Our inspectors understand the planning constraints affecting properties in conservation areas and can advise on issues that might impact future renovation or repair plans. Properties in the Conservation Area and listed buildings are subject to specific planning controls where any external alterations, extensions, or demolition typically require Conservation Area Consent or Listed Building Consent in addition to standard planning permission.

The local geology around Oswestry also plays a significant role in our survey approach. The area includes varied bedrock types from the Silurian and Carboniferous periods, including mudstones, sandstones, and limestones, overlain by superficial deposits of till (boulder clay) and alluvium. Properties built on the boulder clay deposits common in parts of Oswestry face a moderate to high shrink-swell risk, where foundation movement occurs as the clay expands and contracts with moisture changes. Our inspectors are trained to identify the signs of this type of movement and can provide specific guidance on appropriate remedial measures.

Our inspectors regularly identify several recurring defect patterns in Oswestry's housing stock. Damp issues are particularly common in the older properties that make up 25.4% of the local housing stock. Rising damp, penetrating damp, and condensation are frequently found in pre-1919 properties, often due to inadequate ventilation, failed damp-proof courses, or the use of solid walls without modern damp-proofing. These issues can be expensive to remedy and may indicate more significant underlying problems with the property's construction. The solid brick and stone walls common in Victorian and Edwardian properties, while durable, were not built with the moisture management systems found in modern construction.

Timber defects are another major finding in our Oswestry surveys. Woodworm infestation and both wet and dry rot are prevalent in older homes, particularly where damp is present. The combination of timber floors, roof structures, and external timber elements found in Victorian and Edwardian properties creates ideal conditions for these issues. Our Level 3 survey provides detailed assessment of all timber elements and identifies the extent of any infestation or decay, including specific recommendations for treatment and repair.

Roofing problems feature regularly in our Oswestry reports. The slate and clay tile roofs common on older properties show wear and tear over time, with broken tiles, failed lead flashing, and deteriorating ridge tiles being frequent findings. Guttering and drainage issues are also common, and these can lead to water penetration that causes damage to walls and foundations over time. Given Oswestry's flood risk areas near the River Morda and its tributaries, proper drainage is particularly important. We also inspect flat roof areas, which are more common on extensions and outbuildings, for signs of ponding or membrane failure.

Structural movement and cracking are concerns that our inspectors take particularly seriously in the Oswestry area. The combination of shrinkable clay soils, potential mining activity, and the age of much of the housing stock means we frequently identify varying degrees of movement. While minor settlement cracking is common in older buildings and often not structurally significant, our survey can distinguish between this and more serious ongoing movement that may require structural engineer involvement.

• Rising damp and penetrating damp
• Woodworm and timber rot
• Slate and tile roof deterioration
• Subsidence and foundation movement
• Structural cracking
• Guttering and drainage defects

A RICS Level 3 Building Survey is strongly recommended for certain property types and situations in the Oswestry area. If you're purchasing a property built before 1900, which accounts for over a quarter of the local housing stock, the Level 3 survey provides the detailed assessment needed to understand traditional construction methods and their associated maintenance requirements. The solid brick and stone walls, timber floors, and lime mortar used in these properties behave differently from modern construction and require specialist knowledge to assess accurately. The 25.4% of Oswestry homes built pre-1919 represents a significant proportion of the housing stock that benefits from this level of inspection.

Properties showing any signs of structural movement should always be surveyed with a Level 3 inspection. This includes properties with visible cracking in walls, doors and windows that stick or don't close properly, or signs of settlement. Our inspectors can assess whether the movement is ongoing, what may be causing it, and whether remedial works are required. Given the clay soils present in parts of Oswestry and the potential for mining subsidence, this level of detail is essential for properties in at-risk areas. We can advise on whether monitoring or immediate structural intervention is appropriate.

Listed buildings and properties within Oswestry's Conservation Area absolutely require a Level 3 survey before purchase. These properties are subject to strict planning controls, and any future renovation or repair work will need to adhere to specific guidelines regarding materials and methods. The Conservation Area covers the historic town centre, which contains numerous listed buildings representing various periods of Oswestry's development. Our detailed report provides the information needed to understand both the current condition of the property and the constraints that may affect future maintenance and improvement works.

New builds at developments such as Maes-Y-Clawdd (Primesave Properties), Brogyntyn Park (Bellway), and The Coppice (Castle Green Homes) may seem like they wouldn't need a Level 3 survey, but these properties can still benefit from detailed assessment. While less likely to have significant structural issues, a Level 3 survey can identify building defects and construction quality issues that may not be apparent to the untrained eye. Self-build properties or those that have been significantly altered after construction definitely warrant the additional detail that a Level 3 provides.
