RICS Level 3 Building Survey in BS28

BS28 brings a few specific issues that make a RICS Level 3 Survey especially useful. Underneath the area sits the Mercia Mudstone Group, a reddish-brown mudstone with moderate to high shrink-swell potential, particularly where clay content is significant. That can leave homes vulnerable to ground movement, with knock-on effects for foundations and structural stability. Our inspectors are trained to spot the signs and can advise if further specialist investigation is needed.

Close to the River Severn estuary, parts of BS28 face a real risk of flooding from both rivers and the sea. Low-lying spots can also suffer surface water flooding after heavy rain. A Level 3 Survey looks for visible evidence of past flood damage, checks flood resilience measures, and flags risks that are easy to miss on a casual viewing. We examine external ground levels, drainage patterns, and the condition of any flood defence features that may have been installed.

Across BS28, the housing stock spans many periods, from the 10% of properties built before 1919 to modern new builds. Each era tends to bring its own familiar defects. Pre-1919 homes may have solid walls without modern damp proofing, while post-war properties can include concrete systems that are now beyond their design life. Our inspectors know these construction methods well, and can pick out issues specific to each one, from rusting wall ties in cavity wall constructions from the 1970s to deteriorating render on Edwardian villas in Wedmore village centre.

Northwick properties, especially in newer developments, come with their own set of points to check. They are usually built to modern standards, but fast-paced building programmes can still leave construction defects behind, and our detailed inspection will pick up snagging issues that need sorting before completion. We have surveyed many homes in both The Laurels and Northwick Park developments, so we have a clear sense of the common issues affecting these newer properties.

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

From surveying homes across BS28, we keep seeing the same issues crop up. Because of the Mercia Mudstone geology, subsidence and heave are genuine concerns, especially where mature trees stand nearby and their roots draw moisture from the clay soil, causing it to contract. Our inspectors look for diagonal cracks around windows and doors, sticking doors that do not close properly, and uneven floor levels that may point to ground movement. We also check foundations carefully, particularly where homes have been extended or altered over time.

Damp is another regular finding, especially in the older housing stock. Rising damp affects properties without a proper damp proof course, while penetrating damp often comes from defective gutters, damaged render, or failed flashing. In some homes, poor ventilation leads to condensation, particularly in bathrooms and kitchens. Our Level 3 Survey will identify the type and extent of any dampness and recommend suitable remediation. In period properties in Wedmore village, we often come across damp linked to solid wall construction that does not have the cavity wall insulation found in newer homes.

Timber defects also come up often, with wet rot, dry rot, and woodworm affecting both traditional timber-framed buildings and modern homes where timber parts have been exposed to moisture. The roof space is a key part of the inspection, and our surveyors check 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. Near the River Severn estuary, we also look for signs of flooding damage or water ingress from previous years.

Drainage deserves close attention in BS28 because of the clay soil conditions. Clay ground can place a lot of pressure on drainage pipes, which can lead to cracks, displaced joints, and eventual failure. Our inspection includes a visual check of above-ground drainage elements, and we note any signs of subsidence that could point to underground drain problems. We also check septic tanks and soakaways at homes 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

Any property purchase can benefit from a full survey, but some homes in BS28 really do need 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 hidden timber decay that needs expert attention. These older buildings often include character features that can be damaged by unsuitable repairs, so our survey highlights the need for sympathetic materials and techniques. In Wedmore, many of these historic properties have been altered over the decades, and our survey will identify works that may have affected structural integrity.

Listed buildings in BS28, especially around Wedmore where there are numerous Grade I and Grade II listed properties, call for specialist knowledge that our RICS surveyors can provide. We understand the constraints on listed building owners and can point out defects that may need listed building consent to repair. Our report sets out the regulatory requirements and helps you understand the long-term maintenance commitments involved. Properties such as the Church of St Mary in Wedmore show the kind of historic architecture our surveyors are used to assessing, and we bring that experience to residential listed buildings across the area.

Homes in flood risk zones, which affect parts of BS28 near the River Severn estuary, should always have a Level 3 Survey. Our inspectors can assess flood resilience measures, identify signs of previous water damage, and judge whether the property has been properly dried and restored after any earlier flooding events. That sort of information is vital for making an informed decision and budgeting for any work that may be needed. We also give practical advice on flood resilience improvements that could help reduce future flood damage.

Large detached homes, which make up 35% of the housing stock in BS28 with average values of £400,000, are especially well suited to Level 3 Surveys because of their complexity. These properties often have multiple roof structures, complex extensions, and sophisticated systems that need a detailed assessment. Given the higher purchase prices involved, the outlay on a comprehensive survey is often well worth it, because even minor defects can turn into significant repair costs.

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