RICS Level 3 Building Survey in Campton and Chicksands

Campton and Chicksands has an unusually mixed housing stock, from 13th-century churches and 16th-century manor houses through to modern residential developments. For anyone buying here, that creates a more complicated picture, because old and new buildings bring very different risks. Around 40% of homes are Ministry of Defence housing for military personnel, with the rest made up of historic cottages, farmhouses and newer builds. A RICS Level 3 Survey gives us the scope to set out those property-specific issues in proper detail.

Ground conditions matter here. Much of the parish sits on Gault Clay, a soil well known for shrink-swell behaviour. In dry spells it contracts, which can leave foundations settling unevenly, and in wetter periods it expands and pushes upward instead. That movement can produce structural cracking, especially in older homes built before modern foundation designs became standard. During our inspections, we pay close attention to walls, ceilings and foundations for signs of subsidence or heave.

Flooding has also been a real issue locally, including during Storm Henk in January 2024 and again in late 2024. Homes close to the River Hit or Campton Brook are exposed to particular risk, so a Level 3 Survey looks carefully at flood damage, damp penetration and how well the current drainage arrangements are working. That way, we can give a clear view of the property's condition before a purchase goes ahead.

Because we survey across Central Bedfordshire, we already know how these local conditions tend to play out in different buildings. Some older cottages are more vulnerable to foundations shifting in clay, some modern schemes were constructed with deeper piled foundations, and some homes fall within flood zones where a closer inspection is sensible. That local understanding feeds directly into the report we provide.

The geology under Campton and Chicksands needs careful attention in any building survey. Gault Clay extends across most of the parish, while Lower Greensand appears in the northern areas. That clay geology creates the shrink-swell conditions that can trouble foundations, and our inspectors know what to look for. Cracks in walls, sticking doors and uneven floors can all point to movement, and a Level 3 Survey investigates those signs properly.

Flood risk is another major point we cover. The River Hit, also known as Campton Brook, runs eastward through the parish towards the River Ivel, and homes along that route have been hit by repeated flooding in recent years. Where a property sits in a flood-risk zone, we look closely at flood damage, the state of ground-floor finishes and any damp-proofing measures in place. We also assess how water appears to have affected the building before, and what protection may still be needed.

On inspections in this area, we have seen homes affected by flooding during Storm Henk and later events. Months on, the evidence is not always obvious. We check for watermarks on walls, altered electrical sockets at low level, fresh plaster that may conceal earlier water damage, and changes to the building that suggest a past flood problem. It is a thorough process, and it helps us spot issues that might otherwise stay hidden until after completion.

• Ordinary watercourse proximity

Across the properties we survey here, certain defects come up again and again. The most serious is often structural movement linked to clay soil. Buildings on Gault Clay may suffer subsidence in dry periods and heave in wet ones. A common pattern is diagonal cracking from the corners of doors and windows, or cracks that are wider at the top than at the bottom. Our surveyors measure and assess those cracks so we can judge whether the movement is active or historic.

Damp is another recurring issue, especially in the older period homes that form a large part of Campton and Chicksands. Many historic cottages were built without modern damp-proof courses, and even where some damp-proofing exists it can fail or be bridged by raised external ground levels or later internal alterations. We take moisture readings at different heights on the walls to distinguish between rising damp and penetrating damp, including moisture entering through damaged roofs, cracked render or defective rainwater goods.

Timber decay can affect both structural and decorative elements in older buildings. In the roof space, we inspect rafters, purlins and joists for signs of wet rot or dry rot. At ground-floor level, we examine timber floorboards and any structural beams, even where they sit beneath more modern finishes. Homes that have been neglected, or have stayed damp for long periods, are especially exposed to this sort of deterioration, and a Level 3 Survey helps us identify the problem before repair costs escalate.

Roof defects are another regular finding in our surveys of older local properties. Slipped or missing tiles, worn lead flashing around chimneys and poor insulation all come up frequently. Because many homes in Campton and Chicksands are of some age, the roof may include traditional materials such as clay tiles or slates, which often need specialist repair methods. Our surveyors record the roof's condition carefully and set out any work needed to keep the building weather-tight.

• Diagonal wall cracking from foundation movement
• Rising damp in solid-wall construction
• Wet and dry rot in timber elements
• Roof tile deterioration and flashing defects
• Condensation in poorly ventilated properties
• Defective rainwater goods and drainage

Campton and Chicksands has a strong historic legacy, with homes and landmarks spanning several centuries of English architecture. Chicksands Priory is a Grade I listed building from the medieval period, while Campton Manor is Grade II*. The centre of Campton is also designated as an Archaeological Notification Area, so groundworks or major alterations may need consultation with Bedfordshire's archaeology service. Those designations can add prestige, but they also bring obligations for owners.

Where we survey listed buildings or homes in conservation areas, we pay close attention to how defects may affect heritage value. Traditional materials and older construction methods need specialist understanding, and our surveyors are used to assessing historic property of this kind. We identify works that may need listed building consent and can advise where specialist contractors are likely to be required.

The Neighbourhood Plan for Campton and Chicksands places clear weight on protecting historic character while still allowing suitable development. That means major renovations or extensions to older properties need to respect conservation area guidance, and a detailed Level 3 Survey gives us the baseline information needed to plan works sensibly. It is especially relevant while development continues at Greenway, where new homes are being built alongside the historic village centre.

We know that buying a listed building brings extra considerations that do not arise with standard residential property. Repair bills can be higher because traditional materials and specialist craftspeople are often needed. Our report highlights issues that may affect plans for the building and gives guidance on the likely cost of getting it into a good state of repair without losing its heritage value.
