RICS Level 3 Survey in Coulsdon (CR5)

For buyers looking at property in CR5, a RICS Level 3 Survey, often called a full structural survey, is the most detailed residential inspection we offer. Our surveyors are usually on site for several hours, checking far more than surface presentation and focusing on the structural integrity of walls, floors, roofs and foundations. That depth is especially useful here because the local stock ranges from older homes, including several listed properties, to newer builds from different phases of development. In Coulsdon, and especially in Old Coulsdon near the Church of St John the Evangelist, we regularly see features associated with Victorian and Edwardian construction that call for experienced assessment.

We usually suggest a Level 3 survey for properties over 70 years old, homes showing signs of structural movement, buildings of non-standard construction, and any purchase where significant renovations are planned. Around Coulsdon there are many period buildings, including Grade I and Grade II listed properties, and a fuller structural survey can bring out defects that would never show up in a casual viewing. The report sets out clear ratings for each issue we find, from urgent defects needing immediate action through to items for future maintenance. In conservation areas, construction details can be unusual, so our surveyors approach those homes with the added care they often need.

A mortgage valuation is mainly for the lender's security, but a Level 3 survey is there for you as the buyer. We set out practical guidance on condition, likely repair costs and the points worth raising with the seller in light of what we find. That can make a real difference when you are discussing the purchase price or asking for works to be done before completion. Across CR5, we have seen buyers renegotiate successfully after reading our findings, often avoiding thousands of pounds in unexpected repair costs.

In the CR5 area, several kinds of property are particularly well suited to a Level 3 Survey. Victorian and Edwardian homes, common in Old Coulsdon and on the main roads, can hide defects linked to age and traditional construction. New-build houses and conversions, including homes at Cane Hill and Netherne-on-the-Hill, are not automatically free from issues and may still need defects put right by the builder. Listed buildings and homes in conservation areas need more specialist knowledge because of their historic importance and legal protections. The same goes for any property where visible defects or alterations suggest there may be more going on beneath the surface.

• New-build homes and conversions
• Listed buildings and conservation area homes
• Properties with visible defects or alterations

Homebuyers who want the fullest picture of a property's condition usually opt for the RICS Level 3 Survey. We inspect the main structural parts of the building, including walls, floors, ceilings, roofs and foundations, and we also look at damp-proof courses, insulation and ventilation. Visible services such as plumbing, electrical wiring and heating systems are covered in the report as well. Every accessible area is checked thoroughly, with notes on the state of fixtures, fittings and finishes throughout.

Across CR5, certain recurring issues come up often enough that we look for them very deliberately. Dampness is one, particularly in older homes with solid walls rather than modern cavity wall construction. Roofs on period properties also need close attention, especially traditional slate coverings where slipped tiles, damaged flashings and worn felt underlay are not unusual. We also watch for signs of structural movement that might point to foundation problems, something that can matter in places with clay soils prone to shrink-swell movement.

Newer homes need proper scrutiny too. At Cane Hill, Netherne-on-the-Hill and Iron Railway Close, we check build quality closely and note defects that may have appeared since construction. Problems can include Windows and doors that do not seal properly, poor plaster finishing, or mechanical systems that were not fitted correctly. Our approach is just as thorough with recent homes as it is with older ones, so you have a clear view of the property whatever its age.

Part of our job is spotting potentially hazardous materials, including asbestos-containing materials that may be present in homes built before 2000. Where we suspect asbestos, we record the location and explain how it should be managed. We also look for timber decay, woodworm infestation and other defects that can gradually affect a property's structural integrity.

CR5 covers a wide mix of housing, and each type brings its own points for buyers to think about. In Coulsdon, that means sizeable Victorian and Edwardian semi-detached houses, especially around Old Coulsdon, sitting alongside post-war terraces and more recent schemes. Because construction methods vary so much between these homes, our surveyors adjust their focus to the areas most likely to matter. We have surveyed extensively across CR5, so we know the sorts of challenges these different properties can present.

Ground conditions matter in this part of south London. Areas of London Clay are found here, and that can create challenges for foundations. In CR5, some properties may be vulnerable to clay shrink-swell movement, especially during drought and then heavy rainfall. Our surveyors know what to look for, including cracking to walls and doors or windows that have become hard to open or close. Not every property in CR5 will be affected, but for older buildings it remains an important issue, so we look for both existing movement and anything that could increase the risk of future problems.

There are several new-build developments in CR5, including Cane Hill and Netherne-on-the-Hill. Modern regulations and construction methods are a benefit, of course, but they do not prevent defects altogether. We apply the same careful inspection process to these homes, checking workmanship and materials for issues that may not be obvious to an untrained buyer. Having surveyed many properties in these developments, we are familiar with the defects that can show up in recently built homes.

Some CR5 homes sit within, or close to, conservation areas, and that is particularly relevant in Old Coulsdon where many listed buildings are grouped. This can affect any future changes you may want to make, because works to listed buildings need listed building consent as well as planning permission. We can point out issues tied to conservation status and explain what that may mean in practice once you own the property. We also flag alterations that appear to have been carried out without the right consents, as those can cause difficulties later when you come to sell.

• Check for signs of subsidence or structural movement
• Assess roof condition and flashings
• Identify any asbestos-containing materials
• Evaluate damp-proofing and ventilation

From our survey work across CR5, a few defect patterns come up time and again. Dampness is one of the most common, especially in older houses with solid walls finished in original lime-based mortars and plasters. Lime behaves very differently from modern cement-based materials because it lets walls breathe, and where unsuitable modern finishes have been added, moisture can become trapped and create serious damp problems. To assess this properly, we use moisture meters alongside our practical experience to judge both the likely cause and the extent of what we find.

Roof defects are a frequent issue on period homes in the Coulsdon area. Traditional slate roofs can last well, but we still see slipped or broken tiles, failing lead flashings and decay in timber sarking boards. Many CR5 properties are now old enough that original roof materials may be nearing the end of their serviceable life. We inspect the roof space thoroughly, including any flat roof areas that may be vulnerable to ponding and early failure. Chimneys are checked carefully as well, because they are a regular source of trouble on Victorian and Edwardian houses.

Not every home in CR5 shows structural movement, but we do encounter it in some cases, particularly on clay soils affected by seasonal changes in moisture. The signs can include cracking to walls, doors and windows that no longer shut properly, or more obvious distortion in the structure. Our surveyors assess whether the movement appears historic and stable or whether it may still be active and worth referring on to a structural engineer. We explain the significance of any signs clearly and set out sensible next steps.

Older properties often have electrical and plumbing systems that need bringing up to current standards. During the inspection, we look at visible wiring, note the type of consumer unit, consider whether the installation appears modern or dated, and record any obvious safety concerns. With plumbing, we check visible pipework, the materials used and the state of sanitary fittings. If anything gives us cause for concern, we mark it clearly in the report and recommend further investigation by the relevant qualified specialist.
