RICS Level 3 Survey in St Germans

St Germans gives buyers a few very local issues to think about, which is why a RICS Level 3 Survey is often the right fit here. The village sits on the River Tiddy, where it meets the tidal Lynher estuary, so homes in lower-lying spots near the watercourse can carry flood risk. We look at that in every survey, checking the property's position in relation to the river, the state of any flood defences already in place, and any known history of flooding nearby. Where a home falls within designated flood zones, our surveyors look especially closely for signs such as past flood damage, water staining, or remedial works that could point to earlier incidents.

Ground conditions are another part of the picture in St Germans. Beneath the area, the Devonian slates and shales of the Looe Basin Formation are usually stable, but in some places the superficial deposits include clay-rich head deposits. If clay soils are present, our inspectors check for shrink-swell movement, especially close to mature trees where root systems can make movement worse. St Germans is not in a primary tin mining district like Camborne or Redruth, but we still record any unusual settlement that could suggest localised ground instability.

Quite a few St Germans homes sit inside the designated Conservation Area, especially around the historic Port Eliot Estate, St German's Priory, and the village centre. There is also a notable number of Listed Buildings here, from the Grade I listed Priory to many Grade II listed houses, walls, and agricultural buildings. Our Level 3 Survey deals directly with those constraints, flagging work that may need Listed Building Consent and outlining the maintenance obligations that come with historic property. For anyone buying a listed building, we set out the repair and alteration limits that will shape ownership from day 1.

St Germans calls for a careful eye on building materials. Many of the older properties are built in local stone, usually grey or brown slate or shale or granite, and they are often finished with traditional Cornish roughcast render. We understand how those materials behave in the local climate. That matters, because solid wall construction can be vulnerable to penetrating damp, and replacing lime-based renders with modern cement mixes can trap moisture and lead to structural damage. Building dates in the village range from the medieval period to the present day, so construction details can vary sharply from one property to the next.

• 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

The way a property in St Germans was built often depends heavily on its age. Medieval and early modern buildings usually have thick solid stone walls made from local slate or granite from nearby deposits. Those walls are often 400-600mm thick and were constructed without modern damp proof courses, so our surveyors pay close attention to ground floor walls and any evidence of rising damp. Traditional pointing was normally done in lime mortar, which helps the building breathe, but it does need regular maintenance if deterioration is to be kept in check.

By the Georgian and Victorian periods, parts of St Germans saw a more formal style of construction. Homes from those eras often have more regular room plans and higher ceilings, and our inspectors frequently spot features such as bay windows, sash windows with box frames, and decorative stucco or render. Roof structures from the same periods commonly use traditional cut timber, with principal rafters, purlins, and sometimes decorative ridge details. Knowing how these buildings were put together helps us judge later alterations and whether key structural elements have been looked after properly.

On the edges of St Germans, rather than in the historic core, there are also homes from the inter-war and post-war years. These tend to use later materials such as brick, concrete blockwork, and cavity wall construction. We assess them in the context of their construction era and the defects that often go with it, from calcium silicate bricks that can be vulnerable to sulphate attack to cavity wall insulation problems in newer schemes. Different age, different risks.

We give the outside of the building a proper going-over. That means checking stonework, pointing, and render, while also looking for cracks that may suggest movement, signs of damp getting through, and faults in rainwater goods that could be letting water in. In older homes with no modern damp proof courses, we assess how any existing damp proofing is performing and suggest suitable remedial action where needed. Our inspection also takes in porches, extensions, and outbuildings, so you get a rounded view of the property's condition.

Inside the property, we inspect floors, walls, and ceilings for movement, damp, and other structural concerns. Our surveyors also look over joinery, fixtures, and fittings, and check how well windows and doors are operating. We review the electrical, gas, and plumbing installations too, although we always advise that specialist testing and certification should be obtained before completion. At the end, we give an overall view of condition along with a clear rating so you can see the scale of any issues found.

From our work across St Germans, some issues come up time and again. Damp is high on the list, especially penetrating damp linked to exposed positions, defective rainwater goods, or failing pointing in stone walls. Rising damp is common in older buildings that were built without modern damp proof courses, while condensation often shows up in homes with poor ventilation, particularly in bedrooms and bathrooms where moisture levels are highest. Cornwall's coastal-influenced climate can make all of this more pronounced than it would be in more inland places.

Timber defects are another regular finding in St Germans. In older buildings, wet rot and dry rot can affect timber in all sorts of locations, but we see them most often in badly ventilated areas such as roof spaces, under-floor voids, and bathrooms with limited airflow. Woodworm in structural timbers also turns up frequently, so we assess how far any damage extends and set out recommendations for treatment where needed. Our Level 3 Survey reviews all accessible timber elements and identifies places where specialist treatment or structural repair may be necessary. Soft, spongy timber and visible fungal growth, especially around windows and door frames, are often clues to wet rot where water penetration has been occurring.

Roof defects appear consistently in our St Germans surveys. Natural slate roofs, although long-lasting, do deteriorate with age, and slipped, cracked, or missing tiles are a regular issue. Leadwork at chimneys and valleys can also break down, allowing water into the roof structure and then into the rooms below. On older properties, chimney stacks commonly show weathering, damaged flaunching, or deteriorated pointing, sometimes to the point where repointing or partial rebuilding is needed. We check all roof penetrations and highlight anything that may call for prompt repair to stop water ingress.

Movement in St Germans properties is usually limited, but it does need proper assessment when it appears. Homes built on clay soils can show shrink-swell movement, particularly if mature trees are close by. Our surveyors inspect walls for cracking that may indicate differential settlement or a more serious structural problem, and we consider both the cause and whether the movement is historic or ongoing. We also note cases where lintel failure or poor support is behind cracking or distortion around openings. Crack pattern and width tell us a lot about whether movement is active and what sort of remedial work may be suitable.
