RICS Level 3 Building Survey in Swanland

Swanland’s housing stock brings a few awkward issues to the surface, which is why a Level 3 Survey really matters. A good number of homes here date from before 1919, especially inside the designated Conservation Area covering Main Street and West End. Most were put together with solid brick walls, often nine inches or thicker, plus lime mortar and traditional timber elements. They have plenty of character, but they can also hide rising damp, timber rot and structural movement that only a trained eye will spot.

Underneath Swanland, and across the East Riding, the ground is made up of boulder clay deposits left by glacial periods, sitting above the chalk bedrock of the Wolds Chalk Formation. That mix brings a moderate to high shrink-swell risk, especially where mature trees pull moisture from the soil or when drought sets in. Homes close to the established trees along Swanland’s leafy lanes can show subsidence or heave, and those signs need specialist review. We know what to look for in this area, right down to the foundations and the usual markers of ground movement.

Roofing is another point we do not skim over. Many Swanland properties still have traditional slate or clay tile roofs, and these need a careful check for slipped tiles, defective flashings and tired ridge tiles. With an average of 142 defects found across comparable properties in similar East Riding villages, there is a real chance of finding work that needs doing. A Level 3 Survey gives you the detail you need if you want to renegotiate repairs or agree a different price with the seller.

Because Swanland is such a commuter-friendly village, plenty of homes have been modernised or extended over time. We pay close attention to changes that may have gone ahead without proper building regulations approval or planning permission, particularly in the Conservation Area, where any external alteration has to respect the character of the area. Historic homes such as Swanland Hall need especially careful handling, and other old houses do too, not least because East Riding of Yorkshire Council has its own rules to follow.

Several building periods are represented in Swanland, and each one brings its own pattern of defects. Pre-1919 homes in the Conservation Area were built with solid brick walls and lime mortar, which behaves very differently from modern cement-based mortar. Many of these buildings also have timber floor structures at ground level, and those can be vulnerable to damp if ventilation is poor or if the ground has been built up over the years. A proper grasp of traditional construction is essential if the assessment is going to be accurate.

Between 1919 and 1945, cavity wall construction started to appear, although many early examples still relied on traditional timber roof structures. After 1945, concrete tiles and suspended timber floors became more common, while homes from the 1980s onwards usually have modern cavity walls with insulation, trussed rafter roofs and uPVC windows. Each period has its own familiar faults, from mortar decay in older buildings to condensation in newer homes where ventilation is limited.

Swanland’s brickwork, usually red brick in keeping with regional building styles, is generally solid enough, but mortar condition still needs watching, especially on older houses where lime mortar may have broken down. Across the village, tiled roofs, whether slate or clay, need routine maintenance. During our inspections we often come across slipped tiles, damaged ridges and deteriorating lead flashings around chimneys.

Our work across Swanland and the HU14 area has turned up a few repeat offenders that buyers should keep in mind. Damp is one of the big ones, especially rising damp in solid-walled houses built before cavity wall construction became standard in the 1920s. Homes with poor ventilation can also suffer condensation, which may lead to black mould and respiratory problems for people living there. We use professional moisture meters to pick up damp problems that the untrained eye might miss.

Timber issues crop up regularly too, with woodworm affecting older timber members and wet or dry rot appearing where damp has taken hold. Traditional timber-framed windows and doors in period properties often show decay where paint has failed or water has found its way in. Across Swanland, tiled roofs need regular maintenance, and we often find slipped tiles, damaged ridges and deteriorating lead flashings around chimneys. We also see guttering and downpipe faults fairly often, especially where mature trees are close by.

Because of the local geology, foundation condition and ground movement get close scrutiny from us. Homes near the mature trees lining many of Swanland’s lanes can show subtle signs of foundation disturbance. Much of the area sits on boulder clay deposits that expand and contract as moisture levels change, so foundations can move over time. We check external brickwork for cracking patterns that may point to subsidence or structural movement, and where needed we recommend further investigation.

There can be compliance headaches in the Conservation Area, especially where a property has historic status. If alterations have been carried out without the right planning permission or listed building consent, future owners can inherit legal complications. We note features of historical or architectural significance and flag planning constraints that could affect later alterations or extensions. East Riding of Yorkshire Council has specific requirements for conservation areas, and we make sure those are clearly reflected in our reports.
