Structural Survey in Bognor Regis

Bognor Regis has a ground profile that deserves respect. The London Clay Formation beneath parts of the town has shrink-swell potential, while the historic core also sits on sands, silts and clays of brickearth. Along the foreshore, the Bognor Sand Member is exposed, and the drift geology includes clays, sands and gravels from tidal flat deposits with flanking raised beach deposits. That combination can produce differential movement, especially where older houses were built on shallow foundations or where extensions sit on different ground types.

Coastal flooding is another factor that changes the structural picture. Large areas are below high tide level, and coastal areas including Felpham, South Bersted, North Bersted and Shripney are listed as Flood Warning Areas. Arun District Council and the Environment Agency manage 2.3 miles of backshore defences, with timber groynes and rock groynes helping to control winter storms, yet surface water flooding has still hit places such as the Tesco superstore car park on Shripney Road. When ground stays saturated for long periods, boundary walls, retaining walls, pavements and shallow footings can all respond badly.

The housing stock adds another layer. The town centre includes Victorian seaside properties and Regency-styled terraces, while Aldwick and Aldwick Bay have grand 1920s and 1930s homes with traditional brick and timber construction. Bognor Regis Town Hall, designed in 1929, uses yellow Flemish bond brickwork with brown brick and stone dressings and a hipped pantiled roof, which shows the sort of masonry detailing common in local civic buildings of the period. Four conservation areas also sit across the town, including Aldwick Road, Bognor Regis Railway Station, Steyne and Waterloo Square, and Upper Bognor Road, so any alteration close to listed fabric needs careful structural review.

Crack size alone does not tell the full story. Hairline cracks in plaster can be linked to drying shrinkage or minor thermal movement, while moderate cracks in brickwork may need closer checking if they are diagonal, stepped or follow the mortar joints through more than one storey. Severe cracking, especially where a wall has shifted, a corner has opened or a lintel has bowed, needs an engineer on site rather than a remote opinion. Homes in Steyne, Aldwick Bay and the old town often show a mix of old settlement and newer movement, so the pattern matters as much as the width.

Seasonal movement is common on clay soils, and Bognor Regis has enough London Clay influence to make that worth checking carefully. Trees, drains and changes in moisture content can cause minor movement in summer and winter, then the cracks close or open again as the seasons change. Progressive subsidence behaves differently because the movement keeps going, often with doors, skirting and windows showing repeat distortion over time. If the evidence is uncertain, monitoring over 12 months is usually the right route before anyone starts major remediation or submits a subsidence claim.

Thermal expansion and shrinkage also affect long elevations, flat roofs and extensions. A crack near a rear addition in North Bersted may be a movement joint issue, while a horizontal crack or bulging wall in an older brick front on Upper Bognor Road can point to a structural problem that needs immediate action. We recommend urgent inspection where cracking is wide, worsening or linked to slumping floors, because waiting can turn a localised repair into a larger support scheme. Small cracks in render are not all alarming, but the sequence of change tells the truth.

Our structural survey prices start from £500, with the final fee shaped by the property size, access needs and how serious the defect appears to be. A compact flat near the railway station or a simple terrace in the town centre is usually quicker to inspect than a large Aldwick house with extensions, roof voids and hard-to-reach sub-floor spaces. The more complex the movement pattern, the more time we spend checking levels, load paths and crack history. That time protects the quality of the diagnosis.

Report detail also affects value. A basic visual opinion is not the same as an engineer-led report with calculations, repair recommendations and, where needed, specifications for remedial works. In Bognor Regis, that matters because a crack in a Victorian brick wall near Steyne may need a different answer from a movement issue in a 1930s semi in North Bersted or a new-build detail in Bersted. We write the report so it can be used by solicitors, builders, lenders and insurers without further interpretation.

Turnaround is usually 5-10 working days after the visit, although urgent cases can move faster if a purchase deadline or claim timetable is pressing. homedata.co.uk records show that local values changed sharply between 2021 and 2022, with the average property price in Bognor Regis rising by 18.9%, the third biggest increase in the southeast. Against that backdrop, a survey on a home priced at £319,999 at Regis Park or a resale house near £462,146 on the 2021 sold data can be the difference between proceeding with confidence and buying a structural problem.
