RICS Level 3 Building Survey in Isle of Sheppey

A Level 3 is the most detailed RICS Home Survey we offer. Our surveyors inspect all accessible parts of the property, then set out what we can see about construction, materials, defects, maintenance and repair priorities. On the Isle of Sheppey, that matters in places like Sheerness Dockyard and Minster-on-Sea, where older fabric, later alterations and coastal exposure can all sit in one house.

The report goes beyond a tick-box condition note. It explains what a defect means, why it matters, and what can happen if the work is left alone. That is useful where a roof covering is tired near Warden Bay, where a bay window has moved in a terrace off the High Street, or where the sub-floor space in an older property shows damp or timber decay.

A Level 3 survey is still a visual inspection. We do not lift carpets, open up walls, remove fixed floor finishes, run drainage CCTV or test electrical, gas or plumbing systems. If we see something that needs specialist eyes, our report says so plainly, and the next step sits outside the survey itself.

• Roof coverings, chimneys and leadwork
• Loft timbers, insulation and ventilation
• Floors, walls and signs of movement
• Rainwater goods, joinery and accessible services

Much of the island sits on London Clay, and that brings shrink-swell risk into the picture. In practice, that means cracks, distorted openings and movement around older foundations can show up in places such as Sheerness, Queenborough and Minster-on-Sea, especially where the building has been patched, extended or lightly founded. We do not diagnose movement from one crack alone, but we do read the pattern carefully.

Coastal exposure is another part of the story. Flood alerts have affected low-lying land and roads around Sheerness, Minster, Queenborough and Leysdown-on-Sea, while Scrapsgate Drain and Warden Bay Drain are both part of the local flood picture. Salt air and wind-driven rain can age roof coverings, metal fixings and external joinery faster than you may expect, and that matters most on homes close to the seafront or promenades.

Sheerness Dockyard is a conservation area, with Mile Town and Marine Town added later, and the island also has a dense spread of listed buildings. The Sheerness Boat Store is Grade I listed, the Old Boat House is Grade II listed and Rose St Cottage is a Kentish clap-boarded building, so older materials and repair methods matter here. Lime mortar, timber decay, failed paint systems and hidden alterations are all the kind of issues a Level 3 survey is built to spot.

• Cracks linked to clay movement
• Flat roofs reaching the end of their life in holiday homes and later extensions
• Damp around low-lying masonry and older cellars
• Corrosion to exposed metalwork near the port and coast
