RICS Level 3 Building Survey Manchester

A RICS Level 3 Building Survey is the most detailed RICS home survey. Our surveyors inspect all accessible parts of the property, then comment on construction, materials, defects, condition and the repairs likely to be needed. On a Manchester terrace in M16 or a mill conversion in M4, that means looking beyond cosmetic points and judging how the building has been put together, where it is failing, and which issues need urgent attention.

The report does more than list faults. It explains the consequence of not repairing them, so you can decide whether a cracked bay, a tired roof covering or damp staining in a cellar is a small job or a warning sign. In south Manchester, where homes in M20 and M21 can sit on clay with shallow foundations, that detail matters because seasonal movement can be mistaken for something more serious.

A Level 3 survey also helps where the property has been altered. If the house in Chorlton has had a rear extension, a loft conversion or internal wall removal, our report considers how those changes sit with the original structure. It is a visual inspection only, though, so it does not include destructive opening-up, lifting carpets, drainage CCTV, or testing of gas, electrics and other services.

• Accessible loft and roof void inspection
• Sub-floor and visible floor structure review
• External walls, roof coverings and joinery checks
• Repair priorities, maintenance advice and likely consequences if defects are left alone

Manchester's older buildings are often red brick with buff stone dressings, timber sash windows and pitched blue-black slate roofs. In conservation areas such as Graver Lane, the original materials matter because repairs need to fit the age and style of the property, not just the shape of the opening. Our reports look at the fabric as a whole, which is why the same crack can mean very different things on a Victorian terrace and a later conversion.

South Manchester needs special care. Chorlton, Didsbury, Levenshulme and Fallowfield contain houses built on clay with shallow brick strip foundations, sometimes only 20cm deep, and that is why M20 and M21 have a well above national average risk of subsidence. Small stepped cracks, sloping floors and bay-window movement may just show seasonal change, but they can also point to ongoing ground movement that deserves a closer look.

Water is another theme. The River Irwell runs through the city centre, while the River Medlock, River Mersey, River Irk, River Tib and River Roch all affect how the ground and drains behave after heavy rain. Manchester also has surface-water exposure from the Ashton, Bridgewater and Rochdale canals, with research pointing to 163,000 dwellings at high risk from surface water and around 50,000 homes in Greater Manchester exposed to river flooding.

• Edwardian bay windows with cracking around shallow foundations
• 1930s solid floors with failed damp protection
• 1960s flat roofs reaching end of life
