RICS Level 3 Building Survey in Durham

On a Durham purchase, the survey starts with what can be seen and what that suggests about the rest of the building. In County Durham, terraced homes make up 42.4% of sales and semi-detached homes 32.6%, so our surveyors spend time on party walls, roof coverings, chimney stacks, rear returns and the junctions where later work has been stitched into the original house. A Level 3 report does not just say "defect found". It explains what is wrong, how serious it appears, what maintenance is needed and what happens if the problem is left. That matters on an older Durham terrace as much as it does on a newer DH1 plot with a later alteration.

We inspect all accessible parts of the property, including the loft, sub-floor voids where available, external walls, drains visible at ground level, joinery, rainwater goods, internal floors and visible services. Our surveyors follow the RICS Home Survey Standard and record the construction, materials and visible defects in plain English, not boilerplate. If the building has a cellar, an extension, a loft conversion or unusual roof geometry, the report gives that extra work the attention it needs. For homes near Bent House Lane, Old Durham Gate or Sniperley Park, that often means checking whether the visible alterations match the age and style of the structure.

A Level 3 survey is still a visual inspection. We do not lift carpets, open up floors, break back plaster, run drainage CCTV or test the full electrical and gas systems as part of the standard instruction. Those are separate specialist jobs where the report flags a concern. If the surveyor sees movement, serious damp, failed roof coverings or timber decay, the report will say so clearly and point you towards the right follow-up. It is a report for decision making, not guesswork.

• Roof coverings, flashings and chimneys
• walls, pointing, render and cracking
• floors, joists and visible timber condition
• windows, doors, rainwater goods and ventilation
• loft space, sub-floor areas and any accessible cellar
• visible services, consumer unit and obvious safety concerns

County Durham sales data shows terraced homes at 42.4% of sales, semi-detached homes at 32.6%, detached homes at 20.7% and flats at 4.3%, so the local stock is not one-size-fits-all. On older Durham terraces, our surveyors tend to look hard at roof coverings, chimney stacks, pointing, rainwater goods and rear extensions, because that is where deferred maintenance often shows first. On semis, we pay close attention to side walls, bay windows and the junction between original house and later additions. The point is simple: the defect patterns follow the build type, not the postcode label.

DH1 has a different problem set. Bellway's DH1 5RA homes, Sniperley Park and The Green at DH1 bring air source heat pumps, PV solar panels and modern fabric into the local mix, which means the inspection has to check roof penetrations, condensate routes, ventilation and whether the visible finish matches the paperwork. A new home can still have defects, especially if the site has had phased handovers or later changes. The fact that it is modern does not switch off the need for a proper look.

County Durham's new-build market also tells a useful story, with 415 newly built properties sold between April 2025 and March 2026 at an average price of £257,000. The busiest bands were £150k to £200k at 21.7% and £300k to £400k at 19.3%, which fits the spread seen across the county. That matters for Durham buyers because a fresh build can sit next to an older property on the same search, but the risks are different. One may need snagging and service checks, the other may need a roof, damp and movement conversation.

We do not guess at flood risk, geology or mining impact for this exact boundary when the public data is not clear. Instead, our surveyors read the building itself, the site levels, the external drainage routes, visible cracking and the state of the timber and masonry. If something points towards movement, the report will say so and recommend a structural engineer rather than pretending a visual survey can settle the matter. That is especially important in a county where buyers can hear old assumptions about ground conditions long before they see the evidence.

• Older terraces, roof and chimney repairs, party wall cracking and rear additions
• semis, bay windows, side walls and junctions between old and new work
• new-build DH1 homes, roof penetrations, ventilation and commissioning paperwork
• visible signs of damp, timber decay, movement and poor patch repairs
• external levels, rainwater disposal and obvious drainage issues
