Get a Fixed-Price Quote >A typical residential structural inspection in Guildford ranges between £350 and £600. For full calculation packages (e.g., for loft conversions or extensions), fees typically range from £800 to £1,500 depending on the complexity of the property. Properties on London Clay may require additional foundation analysis.
Guildford is largely built on the London Clay formation. This highly shrinkable soil poses significant risks for foundations, particularly in areas like Merrow and Burpham. We specialise in deep-fill foundation design and anti-heave precautions to satisfy Guildford Borough Council Building Control.
Surrey’s mature oak and willow trees extract moisture from clay soil, causing differential settlement. We calculate safe building distances using NHBC Chapter 4.2 guidelines and design foundations that account for both current and future root growth patterns.
Guildford’s historic town centre contains many Grade II listed and conservation area properties. We design sympathetic structural solutions—hidden steelwork, lime-based repairs—that satisfy both Building Control and the Conservation Officer.
