RICS Level 3 Building Survey in Cobham

A Level 3 survey is the most detailed visual inspection we provide under the RICS Home Survey Standard. Our surveyors look at all accessible parts of the property, including roof spaces, internal floors, external walls, chimneys, drainage clues, joinery and visible services, then explain what the defects mean in plain English. On a Cobham house near Cobham Park or one of the listed buildings around Church Cobham, that often means checking the age of the roof covering, the condition of mortar joints and the way later alterations meet older fabric.

The report does not stop at naming problems. It explains the likely cause, the urgency, the repairs needed, and what could happen if you leave the issue alone, which matters on a property where a small patch of cracked render might be masking damp or failed flashing. If the surveyor sees signs that suggest movement, rotten timbers, failing roof structure or a concealed defect, our report flags the issue and recommends the right specialist follow-up, usually a structural engineer, damp specialist or roofer.

What we do not do is just as important. A Level 3 survey is a non-destructive inspection, so we do not lift carpets, open up floors, drill into walls, carry out drainage CCTV, or test gas, electrics or plumbing systems. Those are specialist jobs, and on an older Cobham property with an annexe, a converted outbuilding or a significant extension, it is normal for the report to point you towards separate inspections where the visible evidence justifies it.

• Accessible loft inspection
• Sub-floor review where entry is safe
• Visible roof, wall and chimney assessment
• Clear repair priorities and risk ratings

Cobham is not a generic new-build market. It has been a conservation area since 1970, and Gravesham Borough Council recognises four separate conservation areas here, Church Cobham, Downside Village, The Tilt and Plough Corner. With 4 Grade I listed buildings, 3 Grade II* buildings and 38 Grade II listings, the village contains a lot of fabric that rewards careful inspection rather than quick assumptions.

That matters because older village stock rarely behaves like a modern estate house. Around Cobham Hall, the Darnley Mausoleum and the listed homes at Owletts and Meadow House, our surveyors would expect to see signs of age, previous repair and occasional inconsistency in materials, especially where later extensions meet older walls. In that sort of setting we pay close attention to roof coverings, chimney stacks, junctions between old and new work, and any patch repairs that may have been done in a hurry.

For buyers, the important point is not that a listed house is automatically bad news. It is that small faults can become expensive if they are ignored, and the wrong repair can create another problem later, especially on homes where breathable traditional materials have been covered with modern cement or hard plaster. If a wall has been repointed badly, or a roof has reached the end of its life, the report should say so plainly and explain what that means for the purchase, the budget and the repair sequence.

KT11 relates to a different Cobham in Surrey. For Cobham in Gravesham, the stronger local facts are the conservation area status, the listed building count and the historic core around Cobham Hall and the Darnley Mausoleum. Those are the details that matter when you are choosing between a Level 2 and a Level 3 survey.

• Roof junctions and flashing
• Timber decay in roof and joinery
• Cracked render or failing mortar
• Damp symptoms around older walls and cellars

A Level 3 report is the start of the decision process, not the end of it. If we find movement, the next step is often a structural engineer, because a building surveyor does not produce an engineer's calculations or design drawings. If the issue is damp, rotten timber or roofing wear, we may point you towards a specialist who can test the problem properly and quote for the right fix.

The report can also help with negotiation. If the survey finds a failed roof covering on a house near the Cobham conservation area, a defective lintel or a serious damp route around a later extension, you can ask the seller to reduce the price or carry out agreed works before exchange. Some buyers use the report to set a repair allowance, others ask for vendor action on a specific item, but the key is to use the wording of the report, not guesswork.

Where access is limited, we may suggest extra inspections rather than assume the worst. That can include a drone roof survey, drainage CCTV, an electrician for wiring concerns, a gas engineer for boiler or appliance issues, or a damp specialist where moisture readings and visible staining do not tell the full story. On a property in DA12 or DA13 with several phases of alteration, that layered approach is often cheaper than trying to discover everything from a standard viewing.
