RICS Level 3 Building Survey in West Thurrock & Purfleet (RM20)

The RM20 postcode covers a diverse range of properties, from Victorian and Edwardian houses in established parts of Purfleet and West Thurrock to brand new apartments and houses in developments like St. Clements Lakes and The Shipyard. Each property type brings its own set of potential issues, and our inspectors understand the specific challenges faced by homes in this area. The underlying London Clay geology creates a particular risk for subsidence and heave, especially in properties with mature trees or shallow foundations, and this is something our surveyors specifically look for during every inspection.

Many properties in RM20 were built during the post-war expansion of the 1950s and 1960s, meaning they are now approaching or exceeding 60 years of age. These homes often feature cavity brick construction with concrete tiled roofs, but the passing decades can bring issues such as deteriorating damp-proof courses, worn roof coverings, and the effects of thermal movement on the structure. Our Level 3 Surveys examine all accessible areas of the property, including the roof space, underfloor areas, and outbuildings, providing you with a complete picture of its condition.

The area also includes several new-build developments, and while these properties may be newer, they are not immune to defects. Modern construction methods can sometimes result in different issues than those found in older properties, such as problems with cladding, insulation, or mechanical ventilation systems. Our surveyors are experienced in assessing properties of all ages and construction types, ensuring you receive accurate, relevant advice regardless of the property you are purchasing.

Properties in the Purfleet Conservation Area present additional considerations due to their historical significance and the specific planning constraints that apply. Several listed buildings, including elements of the former Purfleet Garrison and St Clement's Church, are located within this area, and our surveyors are familiar with the special considerations that apply to historic properties. We will note any relevant conservation or listed building considerations in our report, helping you understand any future works or restrictions that may apply to the property.

RM20 is largely situated on London Clay, which is a high plasticity clay with significant shrink-swell potential. This geological composition means the ground can expand substantially during wet periods and contract during dry spells, putting considerable stress on foundations and structural elements. Our surveyors specifically assess signs of movement, cracking, and foundation condition in every property we inspect in this area, paying particular attention to properties with mature trees nearby, which can accelerate moisture changes in the soil.

The superficial deposits of River Terrace Deposits (sand and gravel) can also be found in some areas, particularly closer to the Thames. These different soil conditions can affect how a property performs over time, and our inspectors take account of the specific ground conditions when assessing any visible defects. Properties built on filled ground, which is not uncommon in areas of former industrial use around West Thurrock and Purfleet, may have different foundation requirements and potential issues that we will investigate.

We have found that properties in certain parts of RM20, particularly those with older shallow foundations, are more susceptible to movement related to clay shrinkage. This can manifest as cracking in walls (particularly diagonal cracks around door and window openings), doors and windows that stick or do not close properly, and visible gaps between walls and ceilings. Our detailed report will identify any such signs of movement and advise on whether further structural investigation is recommended.

Properties in RM20 face several area-specific environmental risks that our surveyors take into account during every inspection. The proximity to the River Thames means that parts of Purfleet-on-Thames and West Thurrock are at risk of both fluvial and tidal flooding, particularly in low-lying areas near the riverbank. Surface water flooding can also be an issue due to the relatively flat topography and areas of impermeable surfaces. Our Level 3 Surveys include an assessment of flood risk and any visible evidence of previous flood damage or water ingress.

The industrial heritage of the area, particularly around West Thurrock and Purfleet, means that some properties may be built on previously developed land. While this is often addressed during new development, older properties on brownfield sites could potentially be affected by ground contamination. Our surveyors are aware of these local factors and will note any concerns in their report. Additionally, the ongoing Purfleet Centre Regeneration project is transforming the area with new housing and commercial development, including the new film and television studio complex, which may affect property values and the local environment.

The presence of Conservation Areas in Purfleet, where several listed buildings are located, also means that some properties may be subject to specific planning constraints. If you are purchasing a property in a Conservation Area or a listed building, our surveyors will note any relevant considerations in their report. Understanding these local factors is crucial for making an informed decision about your property purchase in RM20.

The Purfleet Centre Regeneration project is one of the largest ongoing developments in Thurrock, covering approximately 140 acres and transforming the former garrison area into a new mixed-use neighborhood. This development includes the new film and television studio complex, which is expected to create around 2,700 new jobs and significantly impact the local housing market. If you are purchasing a property near this development, our surveyors can provide insight into how it may affect your property in terms of noise, traffic, and future value.

Understanding the construction methods used in properties across RM20 helps our surveyors identify potential issues more effectively. Properties built before 1900 typically feature solid brick walls, timber floors and roofs, slate or clay tile roofs, and lime mortar. These older properties often have significant character but may have accumulated various defects over more than a century of use. Our inspectors are experienced in assessing these traditional construction methods and understanding how they perform in the local conditions.

Properties constructed between 1900 and 1945 saw the introduction of cavity brick walls becoming more common, though many still feature timber floors and roofs with clay tile or slate roofs. The use of cement mortar rather than lime mortar during this period can affect how the property handles moisture. From 1945 onwards, the post-war housing boom brought predominantly cavity brick construction with concrete tiled roofs, and many of these properties in RM20 are now reaching an age where issues such as failing damp-proof courses and deteriorating roof coverings are commonly encountered.

New build properties, particularly those at St. Clements Lakes and The Shipyard developments, use modern timber frame or steel frame construction with brick and render cladding. While these properties benefit from modern building regulations, they can still suffer from defects related to workmanship, material quality, or design. Common issues we find in newer properties include inadequate ventilation leading to condensation, problems with window and door installations, and issues with flat roof coverings.

• Subsidence related to clay shrinkage
• Rising damp and failed damp-proof courses
• Roof tile deterioration and slipped tiles
• Timber rot and woodworm infestation
• Cracking from thermal movement or settlement
• Asbestos in pre-2000 properties
• Surface water drainage issues
• Condensation in poorly ventilated properties
