RICS Level 3 Building Survey in Gerrans

Gerrans has a character of its own, and that often means homes here need a closer look than newer properties elsewhere in the UK. Our surveyors regularly come across issues tied to Cornish coastal buildings, including damp penetration through older stone walls, mundic concrete in homes built between 1910 and 1970, and salt-laden air wearing away external finishes. We also take the local geology seriously. With slate formations along the coastline and hard slate cliffs, ground stability is a key part of how we survey in Gerrans. Cornwall's mining past was not centred on Gerrans itself, but old, disused mines elsewhere in the region can still contribute to ground instability.

Across Gerrans, many homes sit within large conservation areas, so extra planning controls can apply to demolition, small-scale development and tree protection. Some of these buildings date back centuries, including the 17th century, and they often rely on traditional construction methods that need informed assessment. We might be looking at the structural condition of a 17th-century cottage one day, then checking a Victorian terrace near the harbour the next. In both cases, our inspectors know the local building stock well enough to spot problems that a generic survey template could miss. The area's high number of second homes adds another layer, as vacant periods can leave maintenance issues unchecked.

Along Gerrans Bay, coastal erosion is becoming a more serious issue, and some seafront properties may face risk by 2105. Recent assessment of flood and erosion risk for Gerrans Bay found no flood risks, but it did identify meaningful erosion risk that could affect homes on North Parade, River Street and The Lugger. So while immediate flood concerns look limited, the longer-term stability of cliff-side properties deserves careful thought. That matters even more because the coastline is mostly hard slate cliff, but places such as Pendower, Porthcurnick and Portscatho have shown higher erosion rates. In our Level 3 survey, we inspect visible structural elements, foundations and signs of movement so you have clearer information before deciding to buy.

There are 56 listed buildings in Gerrans Parish, including the churches of St Gerrans and St Anthony, several farmsteads, and houses in smaller settlements, with some dating from the 17th century. Homes like these can hide defects behind unusual construction methods, which is why a Level 3 survey is often the sensible option. Listed building consent and planning controls may limit alterations or upgrades, even where works seem straightforward, so it helps to understand the building before you commit. Our report sets out the condition clearly, whether the issue turns out to be dry rot in period joinery or structural movement that needs urgent attention.

We see the same recurring defects across the Roseland Peninsula, and Gerrans is no different. Older homes built from local killas stone and granite can be attractive, but they are often prone to damp and mould, especially where damp proofing is poor, ventilation is limited and thermal insulation is lacking. Solid walls in period properties are particularly vulnerable to rising damp when original lime-based mortars have been replaced with cement render that traps moisture. During the survey, we look closely at the stonework, the pointing and any evidence of water getting in, because small signs of moisture can point to larger structural trouble later on.

Any property built between 1910 and 1970 needs a careful eye for mundic block construction, a distinctly Cornish problem that can affect both structural integrity and mortgageability. Mundic block is a form of concrete made with industrial waste products, and it can deteriorate over time. In some cases, specialist testing is needed to confirm whether a home is affected. Our surveyors will tell you if mundic sampling looks necessary from the age and type of construction, and we can arrange that specialist assessment as part of our service. In Gerrans, that matters because small estates developed in the mid-20th century now make up part of the local housing stock.

Roof defects come up time and again in our Gerrans surveys. We find leaks, structural concerns, poor waterproofing, the wrong fixings, and tiles that have slipped or gone missing. The coastal climate does not help, as salt-laden winds speed up the deterioration of tiles, flashings and mortar. Many older properties here have traditional slate roofs, sometimes original and sometimes replaced over the years, so judging how much life remains in them is an important part of what we do. We also check for timber decay, including dry rot and wet rot, both of which thrive in Cornwall's damp conditions and can do serious damage if left unnoticed.

In Gerrans period homes, outdated plumbing and electrics are a regular finding, and plenty still have wiring dating from the early to mid-20th century. Those systems may fall short of current safety standards and can struggle with modern demand, which creates both risk and expense for a buyer. Homes built before 1992 can also contain asbestos in insulation, floor tiles, roofing and other materials, so that needs specialist identification and careful management. Our Level 3 survey reviews these services as far as visible inspection allows and flags anything that should be followed up by a qualified electrician or plumber.

Each RICS Level 3 Building Survey we carry out in Gerrans follows the RICS methodology and covers all accessible parts of the property in detail. Our inspectors assess the walls, roof, floors, ceilings, doors and windows, and we check both the exterior and interior of the building. Where defects are found, we explain the cause and rate the significance as urgent, serious or minor. The result is a clearer picture before completion, whether the property is a small terraced house near the harbour or a large detached family home.

Our report does more than list problems. It gives specific repair and maintenance advice, estimated costs for major works, and guidance on what should happen before you complete the purchase. In Gerrans, where older homes are common, that could mean recommending re-pointing to traditional stonework, treatment for rising damp in solid walls, or attention to structural movement in a period building. We also look at outbuildings, garages and the wider plot, including boundaries that may be influenced by local geology or coastal erosion risk. Where a property sits in a conservation area, we note planning points that could affect future renovation.

A basic mortgage valuation is not the same thing. A Level 3 survey is prepared for you as the buyer, giving you the detail needed to renegotiate on price if serious defects come to light, or to budget properly for repairs later. In Gerrans, where homes can reach premium values, it is important to know exactly what that money is buying. The defect analysis and cost guidance help with practical decisions, from agreeing a fair figure to planning improvements after completion. Many clients have told us how useful that detail was, especially when unexpected repair costs surfaced before contracts were exchanged.

Cornish coastal property comes with a set of risks our surveyors know well. We watch for salt weathering on traditional stonework, problems linked to older construction methods, and the legacy of historic mining across Cornwall. Signs of subsidence get particular attention, whether the cause may be historical mining, clay shrink-swell soils or coastal erosion affecting foundations. If we think one of those issues may be in play, we recommend further specialist investigation so you can move forward with fuller information.
