RICS Level 3 Building Survey in BS28

The BS28 area presents several specific challenges that make a RICS Level 3 Survey particularly important. The underlying geology consists of Mercia Mudstone Group, a reddish-brown mudstone that has moderate to high shrink-swell potential, particularly where clay content is significant. This means properties in the area can be susceptible to ground movement, with potential consequences for foundations and structural stability. Our inspectors are trained to identify the signs of such movement and can advise on whether further specialist investigation is needed.

Additionally, parts of BS28 lie near the River Severn estuary, where flood risk from rivers and the sea is a genuine concern for property owners. Surface water flooding also affects low-lying areas during heavy rainfall. A Level 3 Survey will assess any visible evidence of previous flood damage, check flood resilience measures, and highlight potential risks that might not be apparent during a casual viewing. We examine exterior ground levels, drainage patterns, and the condition of any flood defence features that may have been installed.

The local housing stock reflects various eras of construction, from the 10% of properties built before 1919 to modern new builds. Each period brings its own typical defects. Pre-1919 properties may have solid wall construction that lacks modern damp proofing, while post-war homes might have concrete systems that have reached the end of their design life. Our inspectors understand these construction methods and can identify problems specific to each era, whether that's rusting wall ties in cavity wall constructions from the 1970s or deteriorating render on Edwardian villas in Wedmore village centre.

Properties in Northwick, particularly those in newer developments, present their own considerations. While generally built to modern standards, these homes may still have construction defects arising from fast-paced building programmes, and our detailed inspection will identify any snagging issues that need addressing before you complete your purchase. We have surveyed numerous properties in both The Laurels and Northwick Park developments, giving us specific insight into common issues affecting these newer homes.

• Clay shrink-swell ground movement
• Flood risk assessment
• Period property defects
• Drainage issues
• Roofing deterioration
• Timber decay

Based on our experience surveying properties throughout the BS28 area, several recurring issues come to light. Given the Mercia Mudstone geology, subsidence and heave are genuine concerns, particularly for properties with mature trees nearby whose root systems draw moisture from the clay soil, causing it to contract. Our inspectors look for diagonal cracks around windows and doors, doors that stick or don't close properly, and uneven floor levels that might indicate ground movement. We also examine the condition of foundations, particularly where properties have been extended or altered over time.

Damp problems are also frequently identified, particularly in the older housing stock. Rising damp affects properties lacking a proper damp proof course, while penetrating damp results from defective gutters, damaged render, or failed flashing. Poor ventilation in some properties leads to condensation issues, especially in bathrooms and kitchens. Our Level 3 Survey will identify the type and extent of any dampness and recommend appropriate remediation. In period properties in Wedmore village, we often find damp issues related to solid wall construction that lacks the cavity wall insulation found in newer properties.

Timber defects remain a common finding, with wet rot, dry rot, and woodworm affecting both traditional timber-framed buildings and modern homes where timber elements have been exposed to moisture. The roof space is a key area of investigation, where our inspectors examine rafters, joists, and purlins for signs of decay or insect activity. Defective roof tiles and deteriorated flashings are also frequently noted, given the age profile of much of the local housing stock. In properties near the River Severn estuary, we also check for any signs of flooding damage or water ingress that may have occurred in previous years.

Drainage issues are particularly relevant in the BS28 area due to the clay soil conditions. Clay ground can put significant pressure on drainage pipes, leading to cracks, displaced joints, and eventual failure. Our inspection includes visual assessment of above-ground drainage elements, and we note any signs of subsidence that might indicate problems with underground drains. We also check the condition of septic tanks and soakaways at properties that are not connected to mains drainage, which is more common in rural parts of the BS28 postcode.

• Subsidence and heave cracks
• Rising and penetrating damp
• Wet and dry rot
• Woodworm infestation
• Roof tile defects
• Drainage failures

While any property purchase can benefit from a comprehensive survey, certain properties in the BS28 area absolutely require the detailed assessment that a Level 3 Survey provides. Properties built before 1900, which make up around 10% of the local housing stock, often have solid wall construction, outdated drainage systems, and may contain hidden timber decay that needs expert assessment. These older buildings frequently have character features that can be easily damaged by inappropriate repairs, and our survey will highlight the importance of using sympathetic materials and techniques. In Wedmore, many of these historic properties have been subject to various modifications over the decades, and our survey will identify any works that may have compromised structural integrity.

Listed buildings in the BS28 area, particularly around Wedmore where there are numerous Grade I and Grade II listed properties, require specialist knowledge that our RICS surveyors can provide. We understand the constraints placed on listed building owners and can identify defects that might require listed building consent to repair. Our report will advise on the regulatory requirements and help you understand the long-term maintenance commitments involved. Properties like the Church of St Mary in Wedmore demonstrate the type of historic architecture our surveyors are experienced in assessing, and we apply this expertise to residential listed buildings throughout the area.

Properties in flood risk zones, which affect parts of BS28 near the River Severn estuary, should always receive a Level 3 Survey. Our inspectors can assess flood resilience measures, identify signs of previous water damage, and evaluate whether the property has been properly dried and restored following any past flooding events. This information is crucial for making an informed decision and budgeting for any necessary works. We also provide practical advice on flood resilience improvements that could reduce future flood damage.

Large detached properties, which represent 35% of the housing stock in BS28 with average values of £400,000, particularly benefit from Level 3 Surveys due to their complexity. These homes often have multiple roof structures, complex extensions, and sophisticated systems that require detailed assessment. The investment in a comprehensive survey is particularly worthwhile given the higher purchase prices involved, where even minor defects can represent significant repair costs.

• Pre-1900 period properties
• Listed buildings
• Properties in flood zones
• Large detached homes
• Properties with extensions
• Non-standard construction
