RICS Level 3 Building Survey in Linkinhorne

Linkinhorne’s housing stock is unusual, and that makes a RICS Level 3 Survey especially worthwhile for buyers here. Across the parish, traditional buildings tend to use granite in grey and cream, with purple and brown slate stones and the striking dark blue and silver Delabole roofing slate. Render also crops up a lot, from roughcast through to wood-float finishes. Beautiful, yes, but these older forms of construction can bring damp penetration, structural movement and age-related wear that a standard survey may miss. Solid walls behave very differently from modern cavity-wall homes in bad weather, and our inspectors know how to read those traditional building fabrics properly.

More than 40 listed structures sit within Linkinhorne Parish, among them the Grade I listed Church of St Melor from the 15th century and the Grade II* listed St Mellor's Well. Henwood, Minions and large parts of Rilla Mill fall within Conservation Areas, while Linkinhorne village is protected too because much of its character remains unspoilt. Buying a listed building, or one in a Conservation Area, brings its own set of issues, and our surveyors are used to judging historic construction methods and spotting work that may need listed building consent. The Linkinhorne Neighbourhood Development Plan puts a clear emphasis on protecting the parish’s character, so any major alterations need to be considered carefully alongside the local planning authority.

The western parish is shaped by granite and killas, the metamorphic rock that comes with it, and the old tin and copper mines add another layer of concern. Linkinhorne was once a major mining district, part of the Cornwall and West Devon Mining Landscape World Heritage Site, and the underground workings can still affect properties now. Marke Valley Mine, a scheduled monument, is noted to be in a precarious state. A detailed Level 3 survey is strongly recommended here, because signs of ground movement or mining-related subsidence are not always obvious in a basic inspection.

We also come across non-traditional homes in the parish, including the pre-cast sectional reinforced concrete buildings known as Cornish Units. Those construction types can suffer from specific problems, for example carbonation of concrete that leads to corrosion of reinforcing steel, and they need the kind of close assessment only a Level 3 Survey provides. From a granite cottage to a 19th-century worker's terrace in Upton Cross, or a modernised farmhouse, our surveyors bring local knowledge to the job and know which issues matter most in this part of Cornwall.

• Properties over 50 years old
• Listed buildings of any age
• Properties with visible defects or alterations
• Non-standard construction (e.g., Cornish Units)
• Properties in flood risk areas
• Converted barns and period cottages

From surveying across Linkinhorne, we’ve seen a handful of issues come up again and again. Damp, both rising and penetrating, is especially common in traditional solid-walled homes built from granite and stone. Where render has degraded, it can trap moisture and trigger internal damp problems that affect the structure and the people living in it. We use moisture meters and thermal imaging to pick up affected areas that a casual viewing would miss. In a parish with solid walls and Cornwall’s wet climate, that sort of check matters a great deal.

Older homes on the granite and killas ground here can move, crack and settle, so structural concerns are never far away. The recent closure of Linkinhorne Parish Hall, after serious structural damage from a water leak that affected floor joists, is a good reminder of what water ingress and timber decay can do to local buildings. Our inspectors look closely at timber condition, including floor joists, roof rafters and any exposed frames, for rot or insect attack. Many properties are old enough that original timbers are nearing the end of their serviceable life, which is exactly why a detailed inspection is so useful.

Lower-lying parts of the parish, especially around Rilla Mill, also have flood risk to think about because of the River Lynher. Parsons Meadow sits within the flood plain and saw significant flooding in December 2020, when the river reached its highest levels in 60 years. Our surveyors check drainage, look for evidence of past water damage and give flood resilience advice where it is relevant. We assess how surface water is managed, examine the drainage systems and note any signs of previous flooding that could affect a purchase decision.

Another issue we often find is poor ventilation, usually caused by well-meant energy upgrades in older houses that have not been thought through properly. If traditional buildings are sealed up without an adequate alternative airflow route, condensation, mould growth and faster timber decay can follow. Our surveyors look at the ventilation strategy and point out where changes may be needed, so the building stays healthy while energy performance improves. That balance matters more and more in historic homes, where warmth and air circulation both need attention.

• Rising and penetrating damp
• Structural cracking and movement
• Roof damage and slate deterioration
• Timber decay in joists and rafters
• Inadequate ventilation
• Drainage and flood risk issues
• Mining subsidence effects

Commissioning a RICS Level 3 Survey for a Linkinhorne property means choosing the most detailed inspection available under the RICS framework. It goes well beyond a basic visual check, with a close look at construction, condition and any defects that could affect value or lead to future spending. We access all accessible areas, including the roof space, sub-floor areas where applicable, and any outbuildings or extensions.

For Linkinhorne’s housing stock, the survey puts particular weight on the condition of granite walls, traditional slate roofs and any signs of movement or deterioration in the structure. Many homes in the parish have been altered over the years, so we also identify changes that may have been made without proper planning or building regulation approval. That is especially important in Conservation Areas, where external alterations are tightly controlled.

The report we provide sets out the property’s condition in a way that is clear and practical. We do not just list defects, we explain what they mean and set out the priority and urgency of any repairs that may be needed. Estimated repair costs are included too, so budgeting after purchase is easier. For older properties, where the scale of the work may not be obvious at first glance, that level of detail is particularly valuable.

Our help does not stop with the survey. Buying a property, especially an older or listed one, often brings questions both during the process and afterwards. Our team can talk through any part of the report, explain technical terms and guide you on next steps if serious defects come to light. Need advice on specialist contractors, or on how to raise concerns with the seller? We can help with that as well.
