RICS Level 3 Building Survey Trowbridge

A RICS Level 3 Survey is the most detailed visual inspection in the RICS home survey range. We look at all accessible parts of the building and comment on construction, materials, defects, condition, repairs and maintenance priorities, then explain what may happen if a fault is left alone. On a stone terrace near the town centre or a brick house off Elizabeth Way, that depth matters because older repairs often hide under newer finishes. It is a visual survey, so we do not open up the fabric, lift carpets, carry out drainage CCTV or test services.

The report is written for a buyer who needs the facts, not reassurance. If we find slipped tiles, failing flashing, uneven floors or signs of damp in a house near the River Biss, we set out what the issue is, what caused it and what type of follow-up may be needed. That can point you towards a roofer, a damp specialist, a structural engineer or a gas engineer. It also tells you whether the matter is urgent or something to monitor after completion, which is the sort of detail a mortgage valuation will never give you.

Trowbridge's housing mix makes that style of reporting useful. Detached homes make up 21.0% of the stock, semi-detached homes 34.2%, terraced homes 27.6% and flats 16.6%, so the town combines later estate houses with narrow older plots and altered semis. Around Drynham Lane, West Ashton Road and the older streets feeding into the Town Centre Conservation Area, one building can have a new extension, an older roof and a patched boundary wall. A Level 3 survey is built for that sort of variety.

• Roof coverings and flashings
• External walls, render and pointing
• Loft timbers and visible roof voids
• Sub-floor areas where accessible
• Rainwater goods, windows and other visible external joinery

Trowbridge sits on a mix of Oxford Clay Formation, Kellaways Formation and Cornbrash Formation, with alluvium and river terrace deposits in places. That matters because shrink-swell clay can move as it gets wet and then dries out, which is one reason cracks and distorted openings deserve close attention on plots near the River Biss or on clay-heavy ground around BA14. Surface water flooding is also part of the local picture, so low-lying homes and gardens need a proper look at drainage, levels and any signs of repeated damp.

The older core tells its own story. Around the Town Centre Conservation Area, The Down and St Stephen's Place, you see stone and brick walls, slate or clay tile roofs, lime-based mortar and timber floors, with some interiors still carrying lath-and-plaster finishes. The usual defects are familiar: penetrating damp, tired pointing, chimney movement, wet rot in roof timbers and woodworm in neglected timber. A Level 3 survey helps separate ordinary wear from more serious movement, especially where a house has been altered and the patchwork of repairs hides the age of the building beneath.

Later stock brings different risks. Post-1945 homes on roads such as West Ashton Road and estates around Elizabeth Way often have cavity walls, concrete tile roofs and shallow details that can fail where gutters leak or ground levels have been raised too high. New-build schemes such as Highfield Gardens, Platinum Place, Ashton Park and Elm Grove still need a close eye on snagging, ventilation, roof detailing and thermal bridges, even if the walls look modern. Older electrics and plumbing can also linger in pre-1980s homes, so cracks, staining or a low reading on the heating system often lead us towards a specialist follow-up.

• Stepped cracking around bay windows
• Damp staining near chimney breasts
• Slipped or aging roof tiles
• Failed gutters and rainwater goods
• Uneven floors on clay-sensitive ground
