The most thorough survey available - ideal for older properties, conversions, and unusual constructions








Our RICS Level 3 Building Survey represents the most detailed inspection available for residential properties in the UK. Formerly known as a Full Structural Survey, this comprehensive assessment goes far beyond the basic visual check provided by standard surveys. Our qualified inspectors examine every accessible element of your property, from the roof structure down to the foundations, providing you with a detailed report that highlights defects, their causes, and recommended remedial actions.
In the SW16 2 postcode area of Streatham, with its mix of Victorian and Edwardian properties alongside modern developments, a Level 3 survey proves particularly valuable. The average property price in this area stands at £521,928, making the investment in a thorough survey a sensible decision for what is likely to be one of the largest purchases you will ever make. Our inspectors have extensive experience surveying properties across Streatham, Streatham Hill, and the surrounding areas, giving them particular insight into the common issues affecting local housing stock.
The area around St Peter's Church in Leigham Court Road saw significant residential development following the opening of Streatham Hill and West Norwood railway stations in 1856, meaning many properties here date from the late 19th and early 20th centuries. This older housing stock, while characterful, brings specific structural considerations that only an experienced local surveyor can fully assess.

A Level 3 Building Survey provides an exhaustive examination of a property's condition, going significantly beyond what you would receive from a Level 2 HomeBuyer Report. Our inspectors visually assess all accessible parts of the building, including roofs, walls, floors, doors, windows, chimneys, and garages. They identify defects, explain their implications, and provide advice on necessary repairs and maintenance. The report includes a thorough evaluation of the property's construction, materials, and overall condition, giving you a complete picture of what you are purchasing.
For properties in SW16 2, this comprehensive approach proves especially important given the age of much of the local housing stock. Many properties in Streatham date from the late 19th and early 20th centuries, meaning they were constructed using methods and materials that differ substantially from modern building practices. Our inspectors understand these older construction techniques and can identify issues that might be missed by a less experienced surveyor or a simpler survey product.
The Level 3 survey also includes a detailed assessment of environmental risks specific to the area. In SW16 2, this includes evaluating the potential for subsidence given the clay soils prevalent throughout London and the South East. The report will note any trees close to the property that might affect foundations, and identify signs of past or present movement that could indicate structural concerns requiring further investigation. Properties along streets such as Leigham Court Road have been specifically identified as having surface water flood risk, making drainage assessment an important part of our evaluation.
Additionally, our surveyors check for signs of sewer flooding risk, as Streatham is identified as being at greatest risk of sewer flooding according to the DG5 Register. This environmental factor, combined with projected increases in intense summer storms due to climate change, makes proper drainage assessment increasingly important for property buyers in this area.
Streatham's housing landscape presents unique challenges that make the comprehensive nature of a Level 3 survey particularly valuable. The area features a diverse mix of property types, from grand Victorian detached homes along tree-lined avenues like Leigham Court Road to smaller terraced houses and modern flats. Each construction type brings its own potential issues, and our inspectors approach each property type with the specific knowledge required to identify relevant defects.
The conservation areas within SW16 2, including properties along Clairview Road, often feature older properties that may have been subject to various alterations over the years. A Level 3 survey examines not only the current condition but also considers the impact of these modifications on the building's structural integrity. This thorough approach helps you understand not just what defects exist, but how they might affect the property's long-term performance and value.

On the arranged date, our qualified RICS surveyor visits your SW16 2 property for typically 2-4 hours, depending on size and complexity. They systematically examine all accessible areas, taking photographs and notes on every aspect of the building's condition. The surveyor will need access to all rooms, the roof space, and any outbuildings.
Within 5-7 working days of the inspection, you receive your comprehensive RICS Level 3 survey report. This detailed document includes our findings, defect classifications, their causes, and clear recommendations for remedial action. The report uses a traffic light system to clearly highlight urgent issues versus those requiring future monitoring.
After receiving your report, you have the opportunity to discuss any findings with your surveyor directly. We explain technical terms in plain English and help you understand what the results mean for your purchase decision. This follow-up service is included as part of your survey fee.
Given the clay soil conditions prevalent throughout SW16 2 and much of Streatham, we strongly recommend a Level 3 survey for any property with significant trees in the proximity or those showing signs of structural movement. The shrink-swell behavior of clay soils accounts for approximately 70% of all subsidence claims in the UK, making professional assessment essential for properties in this area. Properties along Leigham Court Road have been specifically identified as having surface water flood risk, and the London Borough of Lambeth faces risks from multiple flooding sources including groundwater and sewer surcharging.
Our experience surveying properties throughout Streatham and the SW16 2 area has revealed several recurring themes that buyers should be aware of. The older housing stock, particularly properties built before 1919 and during the interwar period, frequently exhibits signs of wear and tear that require attention. Roofing issues rank among the most common defects identified, with older clay tile roofs showing signs of deterioration, slipped tiles, and flashing failures that can lead to water ingress if left unaddressed.
Dampness represents another significant concern in this area's older properties. Rising damp affects many Victorian and Edwardian homes, while penetrating damp can result from degraded pointing, damaged gutters, or compromised roof coverings. Our Level 3 survey provides detailed assessments of damp levels using professional equipment and identifies the most appropriate remediation strategies. Condensation also proves prevalent in older properties that have had modern double-glazing installed without adequate ventilation, a particular issue in the flat conversions common throughout SW16 2.
Timber defects, including both wet and dry rot, frequently appear in properties with age-related building fabric issues. Floor joists, timber framed windows, and structural elements can all be affected, particularly in properties where damp conditions have developed over time. Our surveyors know exactly what to look for and can distinguish between superficial cosmetic issues and serious structural problems requiring immediate attention.
Given the clay geology underlying SW16 2, subsidence and foundation movement remain a critical concern for property buyers. The shrink-swell behavior of clay soils means properties with large trees nearby, particularly those planted within influencing distance of foundations, face heightened risk. The dry summers experienced in recent years have exacerbated this issue across London, and our surveyors pay particular attention to any signs of movement, cracking, or doors and windows that no longer close properly.
Every RICS Level 3 survey in SW16 2 is conducted by a fully qualified surveyor with extensive experience in the local property market. Our team understands the specific characteristics of Streatham's diverse housing stock, from the grand Victorian properties along Streatham Common to the more modest interwar semis that dominate certain streets. This local knowledge proves invaluable when assessing properties, as our surveyors can identify issues that generic surveyors might overlook.
All our surveyors are members of the Royal Institution of Chartered Surveyors (RICS), meaning you receive a report that meets the highest professional standards. They participate in regular continuing professional development to stay current with building regulations, construction techniques, and emerging defect patterns. When you book a Level 3 survey through Homemove, you can trust that your inspector has the expertise necessary to provide an accurate, comprehensive assessment of your potential new home.

The Level 3 survey provides a comprehensive inspection of all accessible parts of the property including the roof space, walls, floors, foundations, chimneys, and any outbuildings. Our surveyor examines the construction and condition of each element, identifies defects, explains their causes, and advises on necessary repairs. In SW16 2 properties, particular attention is given to roofing (especially clay tile roofs on period properties), dampness issues common in older buildings, and any signs of structural movement that might relate to the clay soil conditions in the area.
The duration of a Level 3 survey depends on the size and complexity of your property. For a typical three-bedroom house in SW16 2, you should expect the inspection to take between 2 and 3 hours. Larger properties, detached houses, or those with unusual construction may require 4 hours or more. Our surveyor needs sufficient time to examine all accessible areas thoroughly, so please ensure we have appropriate access to all parts of the property including the roof void and any outbuildings. Properties in the SW16 2 area range from compact flats to substantial Victorian detacheds, so timing will vary accordingly.
While flats may be eligible for a Level 2 HomeBuyer Report, a Level 3 survey is often recommended for flats in SW16 2, particularly those in converted period buildings. The comprehensive assessment can identify issues with the building's common parts, structural concerns affecting the whole building, and specific defects within your flat. Given that many flats in Streatham occupy Victorian or Edwardian buildings with potential shared structural issues, the detailed analysis provided by a Level 3 survey proves particularly valuable for informed decision-making. This is especially relevant for properties in conversions where the original structure may have been modified significantly.
If our Level 3 survey identifies significant defects, your report will provide detailed information about the issue, its likely cause, and recommended remedial action. This might range from minor repairs you can address after purchase to major structural concerns that require immediate attention. Your survey report gives you leverage to renegotiate the purchase price, request that the seller carries out repairs before completion, or in some cases, reconsider the purchase entirely if the issues are too severe. Your surveyor can also recommend specialist contractors if you need further investigation of any identified problems. In the SW16 2 area, where properties command high prices, this negotiating power can represent significant financial value.
Pricing for Level 3 surveys in SW16 2 typically starts from around £600 for smaller properties such as one-bedroom flats, with costs increasing based on property size, value, and complexity. Larger detached houses in the area, which can command prices over £800,000, will naturally require more comprehensive inspections and thus higher fees. We provide transparent pricing with no hidden charges, and you can obtain a specific quote by using our online booking system or calling our team directly. The investment is minimal compared to the property values in this area, where even a small percentage adjustment to the purchase price represents thousands of pounds.
We actively encourage buyers to attend the survey inspection at their SW16 2 property. Being present gives you the opportunity to see any issues firsthand and ask questions as they are identified. Our surveyors are happy to explain their findings in plain English and point out areas of concern as they conduct the inspection. This direct interaction often proves invaluable for understanding the true condition of the property and any implications for your purchase decision. For period properties in particular, seeing the defects explained on site helps you prioritise the remedial work needed.
The clay soils prevalent throughout SW16 2 and the wider London area present specific challenges for property owners. Clay shrinks during dry periods and swells when wet, a cycle that can cause foundation movement and subsidence. This risk is heightened when properties have large trees nearby, as tree roots extract moisture from the soil, accelerating the shrink-swell cycle. Our Level 3 survey includes detailed assessment of trees within influencing distance of the property and evaluates any signs of past or present movement. Properties along Leigham Court Road and other tree-lined streets in SW16 2 receive particular attention in this regard, as the combination of mature vegetation and clay soils creates ongoing potential for structural movement.
Flood risk assessment forms part of our environmental evaluation for properties in SW16 2. The London Borough of Lambeth faces multiple flood risks including surface water runoff, groundwater seepage, and sewer surcharging. Streatham has been identified as having particular vulnerability to sewer flooding according to the DG5 Register. Climate change projections indicate this risk may increase with more intense summer storms. Our surveyors check drainage systems, consider the property's location relative to known flood risk areas, and advise on any remedial measures that might be needed. Properties in lower-lying areas or those with history of drainage issues receive enhanced scrutiny.
