RICS Level 2 Survey in Great and Little Hampden

The housing stock in Great and Little Hampden presents specific challenges that our surveyors encounter regularly. The predominant building materials in this area include brick and flint construction, timber-framed structures, and thatched roofs, all of which require experienced eyes to assess properly. Hampden House, a Grade I listed medieval manor, showcases the area's architectural heritage with parts dating back to the 14th century, featuring traditional clunch (chalk and mud) in its south wing. Many properties in the area were constructed using traditional solid wall methods rather than modern cavity wall construction, which presents unique assessment challenges that generic survey approaches may miss.

Properties in this area face several common defects that a RICS Level 2 survey identifies effectively. The local geology presents a shrink-swell risk due to the chalk plateau overlain with clay and flints, meaning foundations can be affected by moisture changes in the soil. This is particularly relevant for the clay-rich soils found on the higher ground around the parish. Our surveyors examine walls, foundations, and structural elements for signs of movement or subsidence that could indicate foundation problems. The clay subsoils in this area are known to contract during dry summer months and expand during wet periods, potentially causing subtle but significant structural movement in properties with shallow foundations.

The age of most properties in Great and Little Hampden means that dampness is a frequent concern. Rising damp, penetrating damp, and condensation affect many period properties that were built before modern damp-proof courses became standard. Our inspections thoroughly examine walls, floors, and ceilings for evidence of damp ingress, particularly in properties with solid wall construction where traditional methods of moisture management have sometimes been compromised by inappropriate modern materials. The prevalence of buildings dating from the 18th and 19th centuries in the Great Hampden Conservation Area means that many properties will have been subject to various alterations over their lifespan, some of which may have introduced damp-related issues.

The rural nature of Great and Little Hampden also means that properties may face issues not commonly found in urban areas. Our surveyors routinely check for problems related to septic tanks, private water supplies, and drainage systems that serve properties in this parish. Additionally, the proximity of the area to farmland means we pay particular attention to any potential issues with agricultural contamination or historical mining activity in the broader Chiltern Hills region. The combination of historic construction, challenging geology, and rural setting makes a thorough RICS Level 2 survey essential for any property purchase in this area.

• Brick and flint construction assessment
• Roof condition and thatch inspection
• Damp and timber decay analysis
• Foundation and subsidence evaluation
• Electrical and plumbing condition review
• Energy efficiency assessment

Our experience surveying properties throughout Great and Little Hampden and the surrounding HP16 postcode area has revealed several recurring issues. Roof deterioration is common in older properties, where traditional roofing materials have reached the end of their serviceable life. Thatched roofs, while beautiful, require specialized inspection for condition, fire safety compliance, and the presence of any rot or pest damage in the supporting structure. The thatch itself can hide deterioration in the underlying timber rafters and purlins, which our inspectors examine carefully during every survey of a thatched property in this area.

Timber decay and woodworm affect many period properties in the area. The timber-framed construction methods used historically can be vulnerable to fungal decay and insect infestation, particularly where moisture has entered the building. Our surveyors examine all accessible timber elements, including floor joists, roof timbers, and structural frames, for signs of active decay. The combination of traditional timber framing and the area's moisture-retentive soils means that properties in Great and Little Hampden can be particularly susceptible to rot issues if drainage has been compromised or if ventilation is inadequate.

Outdated electrical and plumbing systems are frequently identified in properties built before modern regulations. Original wiring may include vintage cable types that no longer meet current safety standards, while lead or galvanized steel pipes may still be in service. Our Level 2 survey includes a visual inspection of electrical and plumbing installations, with recommendations for further investigation by qualified contractors where necessary. Given the age of many properties in this area, dating from the 18th and 19th centuries, it is common to find that original electrical installations have been incrementally upgraded rather than fully rewired, leaving potentially dangerous combinations of old and new wiring.

Chimney stability is another area of concern in this area. Many properties feature prominent chimney stacks that have deteriorated over decades of exposure to weather. Our inspectors assess chimney breasts, stacks, and flashing for signs of movement, cracking, or water ingress that could indicate structural issues. Additionally, many chimneys in the area will have been capped or sealed at some point, which can lead to ventilation issues within the property. We also note the condition of any remaining chimney pots, as these can deteriorate and pose a safety risk if they become loose.

Some properties in the broader HP16 area may also be affected by radon emissions, a radioactive gas that occurs naturally in certain geological formations. While Great and Little Hampden is not in the highest risk category, the chalk geology of the Chiltern Hills means that certain properties may have elevated radon levels. Our surveyors can advise on whether a radon test is recommended based on the property's specific location and construction. This is particularly relevant for properties with cellars or ground-floor rooms, where radon can accumulate to higher concentrations.
