RICS Level 3 Building Survey in Windsor and Maidenhead

A RICS Level 3 Building Survey is our most detailed visual inspection of all accessible parts of a home in SL4, SL6 and the surrounding borough. We look at the roof covering, chimneys, walls, floors, ceilings, windows, doors, loft spaces, visible timber, drainage clues, damp evidence and the general condition of the structure. The report explains how the home was built, what materials were used, what has gone wrong, what still needs attention, and what may become expensive if left alone. In a place with older stock around Peascod Street and the Royal Station complex, that level of diagnosis matters.

Our surveyors do not open up the fabric of the building, lift carpets, run drainage CCTV or test services as part of the inspection. If the home on Park Street has hidden movement, or a Clewer Waterside property has a damp patch that suggests a leak below the surface, the report will say so and recommend the right specialist follow-up. That can mean a structural engineer, a damp specialist, an electrician, a gas engineer or a drainage contractor, depending on what is seen on the day. The point is to give you the facts without guessing.

The report also sets out repair priorities in order. Some defects are urgent. Others can wait, but only if you know the consequence of delay. A cracked render panel on a stucco front in inner Windsor, a worn slate roof near Oakley Green, or timber decay in an older loft at Maidenhead Road can sit quietly for years before they become more serious. Our reports explain that chain of risk, so you can make a decision with your eyes open.

Local stock shapes the defects we expect. The borough sits on London Clay, so shrink-swell movement can show up as cracking, distortion or localised subsidence, especially where older foundations meet mature trees or altered ground levels. That matters in parts of Windsor, Old Windsor and Cookham, where homes can sit close to the River Thames and its tributaries. As of 21 May 2026 there are no flood warnings or alerts in Maidenhead or Windsor and Maidenhead, but the long-term risk from rivers, surface water and groundwater remains part of the picture.

The older streets tell their own story. Windsor has red brick, yellow brick in Park Street, coloured stucco in inner Windsor, and older Victorian villas with polychrome detailing, while some properties use slate or clay tile roofs that now need renewal or patching. In the borough there are 27 Conservation Areas and 956 Listed Buildings, so changes to windows, roof coverings, render and internal layouts are often part of the survey conversation. A home near the Royal Station complex may have different issues from a 1930s house with a projecting front gable in SL6, and our reports reflect that difference.

Water is another local factor. The River Thames, the Jubilee River relief channel and the wider drainage network shape how homes perform in wet periods, and surface water can be a problem even away from the main river. Maidenhead saw significant surface water flooding in September 2024, so a survey near Braywick Road, York Road or Clewer Waterside needs a sharp eye for high external ground levels, bridging damp, blocked gullies and signs of historic water ingress. Newer homes at Windsor Arch close to Oakley Green can still show snagging, poor detailing or minor weatherproofing faults, so age alone is not the answer.

• River Thames flood exposure
• Surface water and groundwater issues
• Victorian and Edwardian brickwork
• Render, stucco and slate roof wear
