RICS Level 2 Survey in Sennen

Properties in Sennen present unique surveying challenges that differ significantly from inland UK locations. The village's position on the Cornwall coast means buildings are exposed to harsh maritime weather, including strong winds from the Atlantic, salt-laden air that accelerates corrosion, and occasional storm damage during winter months. Many homes here are constructed from traditional granite, a durable material but one that requires specific knowledge to assess properly. Our surveyors understand how coastal conditions affect different construction types and can identify issues that a generic survey might miss. The granite geology beneath Sennen is part of the ancient Cornubian batholith, and properties built on this bedrock face different considerations than those on clay soils further east in Britain.

Sennen also contains numerous historic properties, including several Listed Buildings and properties within the Sennen Cove Conservation Area. These older homes often feature traditional construction methods using local stone, slate roofing, and in some cases cob walls. While charming, these properties can harbor hidden issues such as damp penetration, outdated electrical systems, or structural movement related to age and exposure. The village has properties dating back centuries, and our surveyors understand the particular challenges of assessing buildings constructed with traditional Cornish methods that predate modern building regulations. We check for appropriate ventilation in roof spaces, ensure solid walls aren't being trapped by inappropriate modern materials, and verify that any past alterations preserve the building's structural integrity.

The granite geology that defines Sennen's landscape also brings specific considerations for property condition. While shrink-swell soil risk is low due to the underlying rock, properties in this area may face challenges related to historic mining activity, coastal erosion, and drainage issues common in Cornish coastal villages. Cornwall has a rich history of metalliferous mining, and undocumented mine features can lead to collapse or subsidence. Our surveyors are familiar with these regional factors and include them in their assessment, giving you a complete picture of the property's condition. We also note that Sennen is part of the West Penwith International Dark Sky Park designated in 2021, which tells you something about the low light pollution in this area but also about the exposure properties face.

Modern developments in Sennen, such as the Atlantic Watch eco-homes on Sunny Corner Lane, bring their own considerations. These high-specification properties feature contemporary construction methods including structural steel, sustainable timber, and modern insulation systems. While newer construction typically has fewer defects, our surveyors still check for issues specific to modern building techniques, including proper installation of bi-fold doors, balcony waterproofing, and the effectiveness of mechanical ventilation systems. buying a traditional granite cottage or a contemporary new build, we provide the detailed assessment you need.

Our experience surveying properties across Sennen and the West Penwith area has revealed several recurring issues that buyers should be aware of. Damp and condensation problems are particularly common in older properties, especially those with solid walls rather than cavity wall construction. The use of inappropriate modern materials on traditional granite or cob walls can trap moisture and cause significant damage over time. Many older Sennen cottages were built with solid stone walls that breathe naturally, but modern owners sometimes apply cement-based renders or waterproof membranes that trap moisture inside the wall structure. Our surveyors check for signs of damp throughout the property and identify any factors that might be contributing to moisture problems, including inadequate ventilation in roof spaces and ground floor areas.

Roof conditions are another significant concern in this coastal area. Properties exposed to prevailing winds and salt air experience accelerated deterioration of roofing materials. Slate roofs, while traditional and attractive, can become brittle with age and may suffer from slipped or missing tiles after winter storms. The coastline around Sennen Cove experiences high-energy wave action, and properties closest to the sea can suffer direct wave damage during storms. Our inspection includes a close assessment of the roof structure, coverings, and any signs of leaks or water damage that could lead to more serious problems if left unaddressed. We also check flashings around chimneys and roof windows, as these are common failure points.

Electrical and plumbing systems in older Sennen properties may not meet current standards. Properties built before the 1970s often have outdated fuse boards, rubber-insulated wiring, and galvanised plumbing pipes that are prone to corrosion and leaks. While not always immediately obvious, these issues can represent significant repair costs and safety risks. Our survey includes assessment of visible electrical and plumbing installations, with recommendations for professional inspections where needed. In particular, we note whether the consumer unit meets current regulations and whether visible wiring shows signs of deterioration or DIY modifications.

One specific concern for Cornwall buyers is mundic concrete, a type of concrete blockwork used in properties built between approximately 1910 and 1970 that can deteriorate and lose structural integrity. While not present in all properties, a Level 2 survey includes visual assessment of the property's construction and can identify signs that may indicate potential mundic concerns. If our surveyor identifies any signs suggesting possible mundic blockwork, we will recommend a specialist mundic test before you proceed with your purchase. Properties with concrete blockwork foundations or external walls should be treated with particular caution until testing confirms the concrete is sound.
