RICS Level 3 Building Survey in Mordon

Mordon’s medieval roots mean many homes here need a careful structural eye from surveyors who understand traditional building methods. Around the village, we see everything from farmhouses, cottages and farm buildings to 1950s local authority housing at Harrington View, plus later schemes from the post-1970s and post-1980s periods, including Midgeholme, Lealholme, Fairwinds and West View. That spread of ages and build styles brings different issues with it, depending on the property in front of us. A RICS Level 3 Building Survey is especially useful in Mordon because it picks up the risks tied to each era, from lime mortar construction in older buildings to the modern techniques used in newer developments.

The ground conditions around Mordon call for particular attention, and our surveyors look at that on every inspection. Mordon sits within the Stockton-on-Tees district, ranked 71st out of 413 districts in the UK for domestic subsidence risk, at around 1.55 times the UK average. The reason is the shrinkable clay soils in the area, which swell and contract as moisture levels change through the seasons, sometimes leading to structural movement over time. Trees and hedgerows close to a property can make matters worse by drawing moisture out of the ground, which can show up as cracking in walls and movement in foundations. We check for subsidence, heave and clay-related movement, and we note any cracking pattern or structural movement that suggests those problems.

Mordon also lies within the Durham Coalfield region, and that brings another set of risks for property owners. Historic mining can lead to collapse of underground workings, collapse of mine shafts, infiltration of mine gas and rising mine water, sometimes long after mining stopped. Not every home will be affected, of course, but a Level 3 survey gives our surveyors the chance to spot signs of mining-related subsidence or instability that could affect your purchase. We also strongly recommend a separate Coal Mining Search (CON29M), because it gives clear information on historic mining beneath individual properties, something a visual inspection cannot fully establish.

County Durham’s housing mix helps put Mordon’s properties into context. Across the region, 38.2% are semi-detached, 35.4% are terraced homes, 20.8% are detached properties, and flats make up around 4% of the stock. In Mordon itself, the village has grown through gradual infill, with local authority housing and detached homes creating a streetscape that reflects several periods of building activity. That means buyers here may come across anything from old farmhouses to more modern houses, and each needs a different kind of assessment.

Properties built before 1900, which includes many of Mordon’s original farmhouses and cottages, usually need the most detailed attention in a Level 3 survey. They often use traditional local stone, brick and timber, together with lime mortars, renders and plasters that behave differently from modern materials. Our surveyors know those traditional methods and can spot issues that a less detailed survey might miss, such as decaying timber frames, failing lime mortar pointing or movement in solid wall construction. Original features can also affect both condition ratings and future maintenance, because keeping the character often means using specialist repairs.

The 1950s local authority housing in Mordon, including homes along Harrington View, brings its own construction era and its own pattern of defects. These properties can have different issues from both older and newer homes, with possible concerns linked to the building practices and materials used at the time, such as concrete foundations, system-built elements or original fixtures reaching the end of their service life. Post-1970s and post-1980s homes, including Midgeholme, Lealholme, Fairwinds and West View, tend to reflect more modern standards, but they still benefit from a proper Level 3 inspection to pick up problems that may have built up over decades, from roof covering wear to early subsidence signs.

Mordon’s place in the County Durham housing market means a lot of properties here are bought as commuter homes for people travelling to Durham, Newcastle or Teesside. That demand, together with the village’s rural setting and Conservation Area status, creates a market where homes can fetch premium prices but also carry risks buyers need to understand. Our local knowledge means we can explain how those regional factors affect the properties we inspect, giving context that goes beyond the building’s physical condition.

Mordon is designated as a Conservation Area, so special planning controls apply to properties across the village. The aim is to preserve or improve the area’s architectural and historic character, protecting the features that give Mordon its distinctive rural feel. If you are thinking of buying here, it is important to understand those limits, because they can have a big effect on future alterations or improvements, and on the cost of owning and renovating the property.

Properties in a Conservation Area usually need planning permission for works that would be permitted development elsewhere. That includes roof alterations, dormer windows, replacing windows and doors, and changes to boundary walls. Some parts of County Durham, including areas near Sedgefield, have extra Article 4 Directions that tighten permitted development rights, and we cannot confirm whether that applies specifically to Mordon, but the Conservation Area controls are still wide-ranging. Our surveyors understand these conservation issues and can talk you through how they may affect your intended use of the property before you commit to buy.

For listed buildings, which are common throughout County Durham with over 3,000 listed structures in the county, there are further rules on top of Conservation Area restrictions. Listed building consent is needed for any alteration or extension that affects the building’s character, and demolition is rarely allowed in any circumstances. Our Level 3 survey report includes observations on historical and architectural significance, so you can understand both the property’s value and the responsibilities that come with owning a historic home. That matters in Mordon too, where Conservation Area designation points to properties of architectural or historic interest.
