RICS Level 3 Building Survey in Croydon

A RICS Level 3 Survey is a detailed inspection of all accessible parts of the property. Our inspectors visually check the roof structure, including tiles, flashing, chimneys and parapet walls, looking for deterioration, missing materials or structural movement. We examine walls externally and internally where we can, watching for cracks, bulging, damp penetration, and the condition of pointing and render. Foundations get close attention too, with our surveyors assessing the property for signs of subsidence, settlement or heave, which matters especially in Croydon where London Clay underlies much of the borough. The survey also looks at floors, ceilings, stairs, doors and windows, and how well they are holding up and operating.

We also inspect the property's services, including electrical installations, plumbing, heating systems and drainage. We do not test these systems, but we do visually consider their condition, age and apparent compliance with current regulations where that can be seen. Our inspectors look at outbuildings, garages, boundaries and the surrounding environment too. There is also a section on legal matters that may affect the property, such as planning permissions, building regulations compliance and any issues that local authority searches might reveal. That broader approach gives you a clear picture of the property's condition before you commit to the purchase.

In Croydon's Conservation Areas, such as those in Park Hill, Central Croydon or parts of Purley, our surveyors pay close attention to features of architectural and historical interest. We note any alterations that may need Listed Building Consent, or that could go against Conservation Area requirements. Croydon has 30 Conservation Areas and over 300 listed buildings across the borough, so this is a particularly important check for buyers in established residential streets. Those restrictions matter if you have renovation plans, because a breach can lead to enforcement action and serious financial consequences. Our report sets out those points clearly, so you know both the current condition and any obligations that may come with ownership.

Croydon's construction methods change quite a bit from one era to another, and that shapes what we look for during the survey. Victorian and Edwardian properties built before 1919, common in places like South Norwood and Thornton Heath, usually have solid brick walls using London stock brick, timber suspended floors, slate roofs and shallow brick footings. That means we check for age-related defects such as failed damp-proof courses and structural movement. Inter-war homes from 1919-1945 often have cavity brick walls and bay windows, while post-war buildings from 1945-1980 may include rendered finishes, concrete elements and, in some cases, system-built construction. Our inspectors know these types well, and they know what to look for in each one.

Across Croydon, our inspectors regularly come across the same few issues. Subsidence and heave are especially common in homes built on London Clay, which dominates the north and west of the borough. Properties with shallow foundations and mature trees nearby are particularly exposed to ground movement, and that often shows itself through diagonal cracks in walls, sticking doors and uneven floors. The chalk geology in the southern areas around Purley and Coulsdon creates different issues, although the subsidence risk is usually lower there. Our surveyors know the difference between minor settlement cracks and more serious structural movement that may need a structural engineer.

Older homes in Croydon often show damp-related problems. Victorian and Edwardian properties, which form a large part of the terraced housing in areas like South Norwood and Thornton Heath, commonly suffer from rising damp where the damp-proof course has failed or was never installed. Penetrating damp can come from defective rainwater goods, missing roof tiles or damaged render, and our inspectors assess those elements closely. We also often find wet and dry rot in timber, including floor joists, roof timbers and window frames, particularly where ventilation has been poor or there has been a history of damp. Woodworm is another regular discovery in older houses with original timber elements, and our surveyors will identify any active infestation that needs treatment.

Roofing problems are another frequent finding in Croydon's housing stock. With slate roofs on older homes and tile roofs on mid-century properties, our inspectors often see worn tiles, cracked flashing, defective leadwork and blocked gutters during surveys. Those defects can let water in and lead to internal damage and timber decay. Many homes also keep original sash windows that need attention, with rotten frames, failed seals in double-glazed units and poor operation common in period properties. The post-war stock, including some system-built homes and concrete-framed blocks, brings its own problems linked to the construction methods and materials used at the time.

New-build properties in Croydon's developing areas bring a different set of issues, and our surveyors pick those up as well. Recent schemes such as Morello Quarter in CR0 6BA, Queen's Quarter at St Matthew's Parade and properties on Brighton Road in Purley may show defects in newly installed elements. Newer homes generally need less repair than older ones, but our Level 3 Survey can still identify snagging issues, check building regulations compliance and confirm that things have been installed to acceptable standards. We also note visible asbestos in properties built before 2000, including textured coatings, floor tiles or insulation materials.
