RICS Level 3 Building Survey in Croft-on-Tees

Croft-on-Tees is a historic village set on the alluvial floodplain of the River Tees, and that geology shapes the buildings here more than many buyers realise. Our surveyors know the ground conditions well. The alluvial deposits in the soil can make foundations tricky, especially in older homes where the original build may not have been designed with local movement in mind. A Level 3 survey gets into those structural issues properly, checking foundation depth, wall construction, and any sign of differential settlement that could point to ongoing ground movement.

For anyone buying in this Tees-side village, flood risk is not a box-ticking exercise, it is a real issue. The Environment Agency has classed Croft-on-Tees as a Flood Warning Area, and properties near Monk End Farm and Spa Cottage are especially exposed. We look beyond the current condition of the house and assess how vulnerable it is to flood damage, from drainage and ground floor levels to any sign of previous flooding that may be hidden at first glance. Homes close to the river need careful attention to floor levels, basement or cellar spaces, and the materials used at ground-floor level.

Brick and stone buildings are common in Croft-on-Tees, and many of them date back to the village’s earliest days as a settlement beside the Tees. They have plenty of charm, but they also ask for a more exacting inspection. Solid walls, old roof coverings, and lime-based mortars need an experienced eye. That is where our Level 3 survey comes in. We examine every accessible part of the property in detail, and we know how traditional materials age, whether the house is fifty, a hundred, or even two hundred years old.

Much of the housing in Croft-on-Tees reflects its roots as a North Yorkshire village, with homes built using methods common in the nineteenth and early twentieth centuries. Solid-wall construction is typical, and external walls are often local brick or stone finished with lime-based plaster. Unlike modern cavity walls, these solid walls depend on mass and breathability to deal with moisture, so they need a different approach to inspection than newer buildings. Our inspectors are used to these older methods and can spot when they are working well, or when damp-proof courses have been bridged or modern alterations have gone wrong.

Across the village, roof types change a good deal from one age of property to another. Victorian and Edwardian houses usually have slate roofs, while older cottages may have clay tile, and in some cases thatch. Ground floors can be just as varied, with stone-flagged or slate floors that are prone to dampness, especially where outside ground levels have risen over time in relation to the inside floor. Our surveyors examine these features closely, not just for present condition but for remaining lifespan and any maintenance that may soon be needed after purchase.

Many properties in the village still have traditional lime mortar pointing, and that deserves careful scrutiny during an inspection. If modern cement-based mortar is used on historic buildings in the wrong way, it can lock moisture into the wall and speed up the decay of brick or stone beneath it. We watch for unsuitable repairs, such as cement pointing on lime-built walls, because the damage may not show itself to an untrained eye for years. Original joinery also gets attention, including timber windows and doors, which often add real character but may need restoration or regular care.

Damp comes up often in our survey findings for homes across the village. Much of the housing stock is old enough for rising damp to affect period properties, while penetrating damp is common in solid-wall buildings that never had cavity wall insulation. Our inspectors use calibrated moisture meters and trace the source of moisture ingress, whether that comes from defective rainwater goods, damaged roof coverings, or poor wall ventilation. In solid-wall properties, we also look carefully at any damp-proof course and check whether it has been bridged by raised ground levels outside or unsuitable internal insulation.

Roofing defects are another regular feature in this area. Missing tiles, worn flashing, and sagging roof structures appear often in our reports on older properties. The traditional materials used on period homes, including slate and clay tiles, do not last forever, and many roofs in the village will already have outlived their expected service life. We inspect roof slopes from the loft where access allows, and externally where it is safe to do so, looking for water ingress, tired felt underlay, and the condition of rafters and battens. Flat roof sections, where they exist, get extra attention because they are a frequent source of leaks in older homes.

Given the local geology, structural movement needs careful thought. The alluvial deposits beneath Croft-on-Tees can lead to differential settlement, especially where ground conditions change across the footprint of a property. Our surveyors look for movement such as diagonal cracks in brickwork around openings, doors and windows that stick or will not close properly, and floors that are not level. We judge whether movement appears active and what that means for the building. Where extensions have been added, we pay close attention to the junction between old and new construction, because that is often where movement and water penetration show themselves.

Older homes in the village can also suffer from timber decay, both in the structure and the finishes. Wet rot, dry rot, and wood-boring insect infestation all turn up in period housing here. Our inspectors probe timber elements to see how they are holding up, looking for fungal growth, insect activity, and water staining that points to ongoing moisture problems. Floor joists, ceiling joists, and roof timbers are checked carefully, especially where roof leaks or faulty plumbing may have introduced moisture over time.
