RICS Level 3 Building Survey in Coleby

Coleby, in the North Kesteven district of Lincolnshire (LN5), asks rather more of a buyer than many villages. Most homes here are built from local limestone, a traditional material that needs the right sort of inspection. Stone-built properties rarely have modern damp-proof courses, and they depend on lime mortar to let the walls breathe. Our inspectors know these construction methods well, and we spot problems that a less specialist survey can easily miss. We have seen how the wrong modern repair can speed up decay in these historic buildings.

Many homes in Coleby are listed, so buyers have a few extra things to think about. English Heritage and Historic England statistics show that Lincolnshire has over 7,000 listed buildings, with a notable concentration in rural villages such as Coleby. A Level 3 Survey looks at the condition of historic features, picks up earlier unsuitable repairs, such as cement pointing on lime mortar walls, and flags any structural movement that may need further investigation. We also check against Historic England guidance and explain what listing means for future maintenance and alterations.

Limestone bedrock sits beneath Coleby, and while that is usually stable, there can still be localised problems, including subsidence risk where there has been former mining activity or natural solution features. Surface water flooding also needs checking on the Environment Agency flood map for each property, especially those near lower-lying land or old water features that are not always obvious at first glance. We always suggest checking the specific flood risk for the property being considered, particularly if it is close to the village’s historic watercourses.

Coleby’s Conservation Area brings its own planning rules, so a detailed survey matters. Alterations, extensions, and even repairs to external parts may need planning permission from North Kesteven District Council. Our Level 3 Survey gives a clear picture of the property’s condition, helping with budgeting for maintenance and renovation while keeping the extra costs and permissions linked to historic homes in mind. Any works that may trigger conservation area requirements are highlighted in the report.

Our work across North Kesteven and the surrounding Lincolnshire villages has shown a few issues that come up again and again in Coleby. Damp and moisture penetration are among the most common defects in older stone properties. This often comes from the lack of a proper damp-proof course, or from modern repairs that trap moisture in solid walls. Our inspectors are trained to identify both the symptoms and the causes. We use professional moisture meters and thermal imaging equipment to find hidden damp problems that the untrained eye may not pick up.

Roofing problems are another major concern locally. Many period homes still have original roof structures with clay tile or slate coverings that have faced decades of Lincolnshire weather. Common faults include slipped or broken tiles, failed lead flashings around chimneys and valleys, and timber decay in rafters and purlins. With Coleby’s housing stock, roof coverings are often close to, or already beyond, their expected lifespan, so a close look is important. Where safe, we access roof spaces and report on all roofing elements in detail.

Structural movement, while often historic and stable, still needs professional assessment so it can be separated from active subsidence. Properties on limestone geology can move because of clay sub-soils, tree root activity, or historic mining. Our Level 3 Survey looks closely at crack patterns, wall deflection, and the building’s age to decide whether movement is worrying or simply part of a house settling over many decades. We measure crack widths and track patterns to see whether movement is still going on or has settled.

Chimney stacks are a particular issue in Coleby properties, as many period homes have substantial chimneys that have spent years exposed to the elements. We check them for spalling brickwork, unstable pargetting, and worn flashings. Because these structures can be dangerous if they become unstable, we give clear assessments of chimney condition and any remedial work needed. A number of homes in the village also have redundant chimneys, which call for specific advice on maintenance or removal.

Drainage and guttering in older homes often need attention too. Traditional cast iron gutters and underground drainage runs can corrode or become damaged, leading to water penetration. We inspect all rainwater goods and comment on the condition of drainage systems, including any links to the main sewer. Poor drainage can damage stone walls over time, so this is an important part of our assessment.
