RICS Level 3 Building Survey in Streat

Properties in Streat present specific surveying considerations that differ significantly from modern homes. The village is renowned for its collection of historic buildings constructed using traditional Sussex materials, including knapped flint walls, Horsham slab roofing, and long and short ashlar quoins. Many of these properties, including listed buildings such as Streat Place and the 11th-century parish church, date back several centuries and require an experienced eye to identify potential structural issues that might concern a mortgage lender or insurance provider.

Our Level 3 surveys examine every accessible element of the property, from the roof structure down to the foundations. We pay particular attention to the condition of flint walling, which can suffer from mortar degradation over time, and the state of Horsham slab roofs, which are a distinctive feature of properties in this area. The geological setting of Streat on the Greensand Ridge also means our surveyors are alert to any signs of ground movement or drainage issues that might affect the structural integrity of older foundations.

Given that house prices in Streat have experienced a 32% adjustment from the 2013 peak of £1,935,000, with some postcode areas seeing 6% decreases since July 2022, a thorough survey provides essential protection for what remains a significant financial investment. Our detailed reports help you understand exactly what you are purchasing and any remedial work that may be required.

The South Downs National Park designation means that many properties in Streat are subject to strict planning controls, and our surveyors understand how these restrictions can affect future renovation plans. Whether you are considering extending a period cottage or replacing windows in a listed building, our reports flag any Conservation Area or listed building considerations that could impact your intentions.

• Thorough inspection of all accessible walls, floors, and ceilings
• Detailed assessment of roof condition and structure
• Evaluation of flint wall integrity and mortar condition
• Identification of damp, rot, and timber decay
• Checking of all windows, doors, and joinery
• Assessment of plumbing, electrical, and heating systems
• Evaluation of any extensions or alterations
• Photographic evidence of all significant defects

The distinctive character of Streat comes from its architecture, which reflects centuries of building tradition in this part of East Sussex. Properties in the village commonly feature knapped flint walls, a construction method that involves carefully shaped flints set in mortar to create durable exterior walls. This traditional technique requires specific expertise to assess properly, as the condition of both the flints and the mortar between them can deteriorate over time, particularly in areas exposed to persistent wet weather.

Horsham slab roofing is another defining feature of properties in and around Streat. These heavy stone tiles, traditionally quarried locally, provide excellent weather protection but can become brittle with age and may suffer from slipped or damaged sections. Our surveyors examine roof coverings closely, assessing not only the visible tiles but also the underlying battens, rafters, and any signs of past or present leaks that might have caused damage to internal ceilings or structural timbers.

The presence of Wadhurst Clay in the local geology means our surveyors pay particular attention to foundation conditions and signs of ground movement. While Streat itself does not sit within designated flood risk areas, the Bevern Stream that flows through the area and the underlying clay conditions mean that drainage and subsurface conditions are important factors in our assessment. Properties with original shallow foundations, common in period buildings, may show signs of settlement or movement that require further investigation.

Long and short ashlar quoins - the alternating projected corner stones seen on many historic buildings in Streat - are another feature our surveyors examine carefully. While primarily decorative, these elements can provide clues about the overall structural condition of a building and any past movement that might have occurred since construction.

• Horsham slab roof inspection
• Foundation and ground condition evaluation
• Drainage system assessment
• Listed building considerations
• Conservation Area requirements
• Quoin condition inspection
• Structural movement assessment

Based on our extensive experience surveying properties throughout the Streat area, we have identified several defect patterns that appear regularly in our reports. Understanding these common issues helps you know what to expect when you receive your survey results and allows you to plan for potential remediation costs.

Flint wall deterioration is perhaps the most frequently encountered issue in Streat properties. The mortar between knapped flints can wash out over decades of exposure to rain and frost, leaving gaps that allow water penetration and accelerate further decay. Our surveyors probe mortar joints carefully to assess their condition and identify areas where repointing may be necessary to prevent more serious moisture-related problems.

Horsham slab roofs on older properties often show signs of deterioration that may not be visible from ground level. Slipped tiles, broken fixings, and degradation of ridge sections are common findings that can lead to water ingress if not addressed. Our surveyors access roof spaces wherever possible to examine the underside of roof coverings and assess the condition of supporting timbers.

Drainage issues around period properties in Streat deserve particular attention. With properties often sitting on clay-heavy ground and the Bevern Stream running nearby, effective surface and subsurface drainage is essential. We inspect gullies, soakaways, and ground levels around properties to identify any areas where water might be accumulating near foundations - a particular concern given the shrink-swell potential of clay soils.

• Mortar degradation in flint walls
• Slippage and damage to Horsham slab tiles
• Roof void timber decay
• Rising damp in solid walls
• Inadequate existing drainage
• Foundation movement signs
• Window and door frame rot
• Chimney stack deterioration
