RICS Level 3 Building Survey Folkestone

A Level 3 survey is the most detailed visual inspection in the RICS home survey range. Our surveyor checks all accessible parts of the property, including the roof space, visible structure, walls, floors, ceilings, openings, drainage points that can be inspected from the surface, and any areas under floors or in lofts that can be safely reached. In Folkestone, that often means a careful read of a Victorian bay front in Clifton Gardens, a later rear extension in CT20, or a mixed-age house near Shorncliffe Road where old and new fabric meet.

The report comments on construction, materials, condition and defects, then explains the likely consequences if repairs are left undone. That could mean damp spreading through plaster, roof coverings failing after winter weather, timber decay moving into floor joists, or cracking that needs a closer look because the ground under the building is clay. We do not lift carpets, open up walls, carry out intrusive sampling, test services, or send cameras through the drains as part of the survey itself. Those are specialist jobs, and our report tells you when they are worth arranging.

Folkestone's older housing stock makes that detail useful. A pre-1919 terrace in the West End may show ageing lime mortar, shallow footings and tired rainwater goods, while a 1930s semi in CT19 can still have hidden defects in flat roof additions, lintels or solid ground floors. We write plainly about repair priority, not just fault-finding, so you can see what needs attention soon, what can wait, and what should be priced into the purchase.

• Roof coverings, chimneys and leadwork
• Walls, openings and visible cracking
• Floors, lofts and sub-floor timbers
• Damp, decay and signs of movement

Folkestone's housing mix tells you a lot about what to expect inside the walls. Many older homes use red brick with slate or clay tile roofs, timber sash windows and rendered fronts, especially in The Bayle, the West End and Clifton Gardens. Those are the places where we often see ageing mortar, failing flashings, timber decay and damp tracking in through tired rainwater goods. The geology matters too. Much of the town sits on Gault Clay, which has moderate to high shrink-swell potential and can move when soils dry out or become saturated.

That clay risk shows up as cracking, sticking doors, sloping floors or movement around bay windows and extensions. In a Victorian terrace close to the harbour, the issue may be shallow foundations combined with weathering from salt-laden air. In an inter-war semi off Shorncliffe Road, the problem could be a later flat roof, failed felt, corroded metal lintels or old drainage that has never been properly checked. Surface water flooding is also worth bearing in mind in built-up parts of town, while the lower reaches near the River Pent and the seafront can face coastal or tidal pressure in bad weather.

Conservation areas add another layer of risk and cost. The Bayle Conservation Area, Clifton Gardens Conservation Area, West End Conservation Area and Folkestone Harbour Conservation Area all contain a high concentration of listed and older buildings, so repairs may need more careful detailing than a standard modern house in CT19. We see plenty of properties where a repair done years ago no longer matches the original fabric, such as hard cement pointing on soft brick, replacement windows that trap moisture, or patched roofs that look fine from the street but are near the end of service life.

• Victorian and Edwardian homes may show subsidence, roof spread, rotten lintels and damp around bays
• Inter-war homes can hide cavity wall issues, concrete lintel corrosion and worn flat roof add-ons
• Coastal properties may suffer accelerated decay to metal, render and paintwork
• Older drains and service runs may need specialist follow-up before exchange
