RICS Level 3 Survey in St Germans

The village of St Germans presents unique challenges for prospective buyers that make a comprehensive RICS Level 3 Survey particularly valuable. The settlement sits on the River Tiddy, which flows into the tidal Lynher estuary, creating flood risk for properties in low-lying areas adjacent to the watercourse. Our inspectors assess flood risk as part of every survey, examining the property's position relative to the river, the condition of any existing flood defences, and the history of flooding in the area. Properties in designated flood zones receive particular attention, with our surveyors documenting any evidence of previous flood damage, water staining, or remedial works that may indicate past incidents.

The geological conditions around St Germans add another layer of consideration for structural surveys. The underlying Devonian slates and shales of the Looe Basin Formation are generally stable, but superficial deposits can include clay-rich head deposits in certain areas. Where clay soils are present, our inspectors look for evidence of shrink-swell movement, particularly near mature trees where root systems can exacerbate ground movement. While St Germans does not sit within a primary tin mining area like Camborne or Redruth, our surveyors still note any signs of unusual settlement that might indicate localized ground instability.

Many properties in St Germans fall within the designated Conservation Area, particularly around the historic Port Eliot Estate, St German's Priory, and the village centre. A significant proportion of homes are Listed Buildings, ranging from the Grade I listed Priory to numerous Grade II listed residential properties, walls, and agricultural structures. These designations bring specific constraints that our Level 3 Survey addresses, highlighting any works that may require Listed Building Consent and advising on the maintenance requirements that apply to historic properties. If you are purchasing a listed building, our survey provides essential guidance on the repair and alteration restrictions that will affect your ownership.

The construction materials common to St Germans demand specialist knowledge during inspection. Local stone, typically grey or brown slate or shale or granite, forms the walls of many older properties, often finished with traditional Cornish roughcast render. Our inspectors understand how these materials perform in the local climate, recognising the particular vulnerabilities of solid wall construction to penetrating damp and the importance of maintaining traditional lime-based renders rather than applying modern cement mixes that can trap moisture and cause structural damage. The village has seen various phases of development from the medieval period through to the present day, meaning properties may date from multiple periods and exhibit different construction characteristics.

• Properties in flood risk zones
• Pre-1919 traditional constructions
• Listed Buildings and Conservation Area properties
• Properties with visible defects or structural movement
• Large or complex residential buildings

Properties in St Germans reflect the village's long history, with construction methods varying significantly depending on the age of the building. Medieval and early modern properties typically feature thick solid stone walls, often constructed from local slate or granite quarried from nearby deposits. These walls, typically 400-600mm thick, were built without modern damp proof courses, meaning our surveyors pay particular attention to the condition of ground floor walls and any signs of rising damp. Pointing between stone blocks was traditionally achieved using lime mortar, which allows the building to breathe but requires ongoing maintenance to prevent deterioration.

The Georgian and Victorian periods brought more refined construction to parts of St Germans, with properties featuring more regular room layouts and taller ceiling heights. Our inspectors see evidence of these periods in bay windows, sash windows with box frames, and decorative stucco or render finishes. Roof structures from these periods typically use traditional cut timber with principal rafters, purlins, and often decorative ridge details. Understanding these construction types helps us identify where alterations may have been carried out and whether structural elements have been properly maintained.

Properties from the inter-war and post-war periods, though less common in the historic core of St Germans, do exist on the village outskirts. These properties often use more modern materials including brick, concrete blockwork, and cavity wall construction. Our surveyors assess the condition of these properties with reference to their construction era, identifying common defects associated with building practices of those periods, from the use of calcium silicate bricks prone to sulphate attack to the potential for cavity wall insulation issues in more recent developments.

The external walls receive thorough inspection, with our surveyors examining the condition of stonework, pointing, and render. We identify cracks that might indicate structural movement, areas of damp penetration, and defects in rainwater goods that could be causing water ingress. In older properties without modern damp proof courses, we assess the effectiveness of any existing damp proofing and recommend appropriate remedial measures. The inspection extends to porches, extensions, and any outbuildings, ensuring you have a complete picture of the property's condition.

We inspect the internal fabric of the property, including floors, walls, and ceilings, looking for signs of movement, damp, or structural defects. Our surveyors examine the condition of joinery, fixtures, and fittings, and assess the functionality of windows and doors. We also inspect the electrical, gas, and plumbing installations, though we always recommend that you verify these are tested and certified by relevant specialists before completion. The survey concludes with an overall assessment of the property's condition and a clear rating that helps you understand the extent of any issues discovered.

Our experience surveying properties throughout the St Germans area has revealed several recurring issues that prospective buyers should be aware of. Damp problems feature prominently in our surveys, particularly penetrating damp caused by the property's exposed position, defective rainwater goods, or deteriorating pointing in stone walls. Rising damp affects many older properties built without modern damp proof courses, and condensation is common in properties with inadequate ventilation, particularly in bedrooms and bathrooms where moisture generation is highest. The coastal-influenced climate of Cornwall means properties can experience damp issues more severely than in more inland locations.

Timber defects represent another significant category of findings in St Germans properties. Wet rot and dry rot affect timber elements throughout older buildings, with particular prevalence in areas of poor ventilation such as roof spaces, under-floor areas, and poorly ventilated bathrooms. Woodworm infestation is frequently identified in structural timbers, requiring assessment of the extent of damage and recommendations for treatment. Our Level 3 Survey examines all accessible timber elements and identifies any areas requiring specialist treatment or structural repair. The presence of wet rot is often indicated by soft, spongy timber or visible fungal growth, particularly around windows and door frames where water penetration is common.

Roofing issues consistently feature in our St Germans surveys. The natural slate roofing common to the area, while durable, suffers from deterioration over time, with slipped, cracked, or missing tiles a regular finding. Leadwork around chimneys and valleys can deteriorate, causing water penetration into the roof structure and interior spaces. Chimney stacks, particularly those on older properties, often show signs of weathering, damaged flaunching, or deteriorated pointing that may require repointing or even partial rebuilding. Our inspectors assess the condition of all roof penetrations and identify where immediate repairs may be needed to prevent water ingress.

Structural movement, though usually minor in St Germans properties, does occur and requires careful assessment. Properties built on clay soils may show evidence of shrink-swell movement, particularly where mature trees are present. Our surveyors examine walls for cracks that might indicate differential settlement or more serious structural issues, assessing the nature and cause of any movement and whether it represents a current or historic problem. We identify where lintel failure or inadequate support may be causing cracking or distortion in openings. The pattern and width of cracks help us determine whether movement is active and what remedial action may be appropriate.
