RICS Level 3 Building Survey in Wycliffe with Thorpe

Wycliffe with Thorpe is a striking rural parish on the south bank of the River Tees, around 5 miles east-southeast of Barnard Castle. It takes in the hamlets of Wycliffe and Thorpe, across 1,019 hectares of mixed ground shaped by fertile farmland and classic North Pennine scenery. The 2021 census records just 204 residents, so it remains one of the more sparsely populated parts of County Durham, yet it also has an unusually rich run of historic buildings that call for experienced surveying attention.

Housing here is quite unlike what we see in towns and cities. Thorpe Hall, a country house dating from about 1740 with earlier fabric built in, is a good example of the complicated construction history our surveyors often deal with. This Grade II* listed building, with its ashlar front, rubble stone elsewhere and graduated Lakeland slate roofs, shows the traditional materials used across the parish. Wycliffe Hall and a number of old farmhouses add to a stock that is dominated by pre-1919 homes built from local stone and finished with traditional slate roofing.

Because these buildings are old and of a particular type, our inspectors keep finding the same kinds of defects. Damp, especially rising and penetrating damp, crops up often in solid-walled stone properties where the original lime mortar pointing has broken down. Timber problems, including rot and woodworm activity, also affect floor joists, roof timbers and window frames in homes of this age. Roof deterioration involving slate, leadwork and the timber beneath needs a close look, as does any structural movement that may have built up over centuries of settlement.

The parish includes several notable listed buildings, and they need a careful hand when surveyed. The Grade I Church of St Mary the Virgin, a 14th-century structure, is one of the oldest buildings in the area, while the Grade II listed Whorlton Bridge is an important piece of 19th-century engineering heritage. Our surveyors know how to assess properties within this historic setting, with an eye on both their importance and the maintenance issues they bring.

• Stone wall construction and lime mortar deterioration
• Historic timber frame elements
• Traditional slate roofing systems
• Drainage and service installations
• River Tees flood risk considerations
• Listed building compliance requirements

Our RICS Level 3 Survey report goes well beyond a standard HomeBuyer Report. We inspect the property condition across nine specific areas, and we rate each defect by urgency and severity. Instead of a traffic light system, our Level 3 reports give full narrative descriptions of every issue we find, setting out the cause, the implications and the recommended remedial action.

For properties in Wycliffe with Thorpe, we pay close attention to the challenges that come with historic stone construction. We look at the condition of pointing and mortar joints, check for any movement in load-bearing walls, and assess the effectiveness of existing damp proof courses, or the absence of them in older homes. Where we spot something that needs further investigation, such as suspected subsidence or serious timber decay, we clearly recommend the right specialists before you commit to the purchase.

The report also includes a property valuation and a reinstatement cost assessment for insurance purposes. With premium values in this area, detached properties regularly passing £600,000 and exceptional homes reaching over £1 million, that valuation element helps keep building insurance at the right level. Our reinstatement figures reflect the particular cost of repairing traditional stone buildings, which often comes in above standard modern construction estimates.

When we surveyed South Thorpe, a detached property that sold for £1,050,000 in July 2024, our report had to reflect the high rebuild costs of a substantial period home in this area. In the same way, when we assess homes like the Old Dairy House, which sold for £625,000 in February 2023, we make sure our valuation and reinstatement figures match what it would really cost to rebuild or repair these traditional buildings with the right materials and skilled labour.

Wycliffe with Thorpe sits on the south bank of the River Tees, so flood risk is a real point for property purchasers in the area. The parish has an attractive riverside setting that has drawn residents for centuries, but homes in lower-lying spots may be exposed during periods of heavy rainfall or snowmelt from the Pennines.

During a Level 3 Survey, our inspectors look for visible signs of past water ingress, check the condition of drainage systems and assess the site’s topography in relation to water courses. Where we identify concerns, we recommend the appropriate investigations and may suggest checking the Environment Agency flood maps for the Tees area. That matters especially for properties in the lower parts of the parish or those with large gardens stretching towards the river corridor.

Homes with a record of flooding may need remedial work such as damp proof course installation, tanking of lower floor walls, or better drainage. Our survey reports set out any such requirements clearly, so you can build remediation costs into your purchase decision or negotiate suitable adjustments with the vendor before completion. We have seen similar Teesdale properties where flood resilience measures have already been put in place, and we can advise on what to look for and what those measures may involve.

Properties in Wycliffe with Thorpe mainly use traditional North Pennine construction methods that are very different from modern building techniques. The larger historic buildings in the area were usually built with locally sourced stone, often rubble or roughly-coursed squared stone for the main walls, with more refined ashlar reserved for the most prominent facades. That variation in build quality within one property reflects the old habit of putting more money into the elevation most likely to be seen.

Lime mortar was the traditional binding agent for these stone buildings, and its deterioration is one of the most common issues our surveyors pick up. Unlike modern cement mortar, lime mortar lets moisture evaporate from within the wall structure, but it needs regular maintenance and repointing. Where cement-based mortars have been used in later repairs, moisture can be trapped behind them, which speeds up decay in the stone and mortar beneath. Our inspection looks carefully at the condition and type of pointing throughout the property.

The graduated Lakeland slate roofs seen on properties like Thorpe Hall are another defining feature of the area. These roofs were made with slates of varying thickness, thicker at the bottom and gradually thinner towards the ridge. It is a handsome traditional approach, but it needs an experienced assessment as the fixings and battens age. Leadwork around chimneys, valleys and rooflights is especially prone to deterioration and is a common source of water ingress in period properties throughout Teesdale.
