Our RICS Level 3 Survey, also known as a Building Survey, is our most comprehensive inspection service. Unlike less detailed assessments, this survey examines the entire property in depth, including structural elements, finishes, and hidden defects that might not be immediately visible. Our inspectors will assess walls, floors, ceilings, roofs, stairs, and windows, providing you with a detailed report that highlights any issues requiring attention.
The survey report includes a thorough analysis of construction materials and methods, identification of any visible defects, and an assessment of the property's overall condition. We look specifically at signs of damp, timber decay, structural movement, and any issues arising from the local geology. Given that PO13 9 sits on clay deposits from the Bracklesham Group and London Clay Formation, our surveyors pay particular attention to potential shrink-swell behaviour that can affect foundations over time.
We also assess the risk from environmental factors specific to this coastal area. Properties in Lee-on-the-Solent can be affected by coastal flooding and tidal influences from Portsmouth Harbour and Fareham Creek. Our survey will identify any signs of previous flood damage and advise on the necessity of further specialist flood risk assessments for properties in vulnerable locations.
For properties near the waterfront or along Marine Parade, we pay special attention to tidal surge risks and the condition of sea defences. Properties in these locations may have specific insurance requirements or mortgage conditions related to flood risk, and our survey provides the detailed information you need to satisfy lenders and insurers.

Simply choose your property type and provide the address in PO13 9. We'll arrange a convenient appointment time for our surveyor to visit the property. Once you book, we'll send you confirmation details and any preparation instructions to ensure the inspection runs smoothly.
Our qualified RICS surveyor visits the property and conducts a thorough visual inspection of all accessible areas. The inspection typically takes between 2-4 hours depending on the property size and complexity. We examine the roof space, under-floor voids, and all accessible interior and exterior elements.
Within 3-5 working days of the inspection, you'll receive your comprehensive RICS Level 3 Survey report. This includes clear ratings for each element, photographs of any defects, and practical recommendations. The report uses traffic-light coding so you can quickly identify the most serious issues.
If you have any questions about the findings, our team is here to help you understand the report and what it means for your potential purchase. We can explain technical terms, discuss priority repairs, and advise on next steps whether that's negotiating the price or requesting further specialist investigations.
Given the clay geology underlying much of the PO13 9 area, we recommend a Level 3 Survey for any property with trees nearby or any visible signs of movement. The shrink-swell risk from London Clay can cause foundation issues that are not always apparent during a casual viewing. A detailed survey can identify these concerns before they become expensive problems.
The PO13 9 postcode covers Lee-on-the-Solent, a coastal area with a diverse mix of property types and ages. From inter-war semi-detached houses built in the 1920s and 1930s to modern developments, each property brings its own set of characteristics and potential issues. Our Level 3 Survey is designed to uncover the true condition of whatever property you are considering.
Older properties in the area, particularly those built before 1945, may have hidden issues such as outdated electrical wiring, original plumbing that has reached the end of its service life, or roof structures that have deteriorated over decades. Our surveyors have extensive experience with the traditional brick and render construction methods common in Gosport, and they know exactly what to look for when assessing these older homes.
Many properties in Lee-on-the-Solent were built during the inter-war period when building regulations were less stringent than today. These homes may have solid walls without cavity insulation, original single-glazed windows, and suspect electrical installations that would fail modern Part P regulations. Our detailed survey identifies these issues so you can budget for necessary upgrades.
The coastal environmentates wear on building materials. Salt-laden air from Portsmouth Harbour corrodes metal fixtures, degrades render finishes, and can penetrate into brickwork causing efflorescence and spalling. Our surveyors specifically assess the condition of external rendered finishes, metal, and rainwater goods that are most vulnerable to this type of deterioration.

Properties in PO13 9 are predominantly constructed using traditional methods common throughout the Gosport peninsula. The majority of homes feature solid brick walls with rendered finishes, typically in red or yellow brick, topped with tiled roofs. Properties built after the 1930s generally feature cavity wall construction, while earlier homes may have solid walls that require different assessment criteria for insulation and damp resistance.
The local geology presents specific considerations for property owners and buyers. The combination of Head deposits (comprising clay, silt, sand, and gravel) overlying the Bracklesham Group and London Clay Formation means that properties in this area face a moderate to high risk of clay shrink-swell behaviour. This occurs when clay soils expand during wet periods and contract during dry spells, potentially affecting foundations. Our surveyors will look for signs of this type of movement, including cracking patterns and door alignment issues.
Coastal proximity is another significant factor for properties in PO13 9. While Lee-on-the-Solent is not typically subject to severe erosion in the same way as some other parts of the Hampshire coast, properties near the waterfront or in low-lying areas do face potential flood risks from tidal sources and surface water accumulation. Properties with sea views or those located close to Fareham Creek should receive particularly careful assessment.
The Gosport peninsula has a military heritage, and some properties in the area may have been built using Ministry of Defence (MOD) standard construction methods or may have been subject to previous MOD ownership. These properties can sometimes have non-standard construction details that require specialist assessment. Our surveyors are familiar with the various construction types found throughout the PO13 9 area and will identify any unusual features in your property.
Our experience surveying properties across Lee-on-the-Solent and the wider PO13 9 area has given us insight into the typical issues affecting homes here. Older properties, particularly those constructed before the Second World War, frequently exhibit signs of rising damp, especially where original damp-proof courses have failed or were never installed. Timber defects are also common, with woodworm and wet rot affecting roof structures and window frames that have been exposed to decades of coastal weather.
Properties of all ages in this area can suffer from issues related to the local environmental conditions. The proximity to the coast means that salt-laden air can accelerate the deterioration of external metalwork and render finishes. Additionally, the clay soils can cause foundation movement, particularly in properties with inadequate foundations or those that have been affected by changes in nearby vegetation or drainage. Our Level 3 Survey is specifically designed to identify these issues and provide you with the information needed to make an informed decision.
One issue we frequently encounter in PO13 9 is render failure on external walls. The combination of age, coastal exposure, and previous poor maintenance means many properties have cracked or blown render that allows water penetration. This can lead to internal damp problems and damage to internal plasterwork. Our survey identifies the extent of render issues and advises on appropriate remediation.
Roof defects are another common finding, particularly on older properties with original clay tiles. After decades of exposure to wind, rain, and salt air, tile bedding mortar deteriorates, leading to slipped tiles and potential water ingress. Our surveyors access roof spaces where safe to do so and assess the condition of tiles, flashing, and roof structure.

A Level 2 Survey provides a good general overview suitable for modern properties in reasonable condition, while a Level 3 Survey offers a much more detailed assessment. The Level 3 is recommended for older properties, those with visible defects, unusual construction, or if you simply want the most comprehensive information available about the property's condition. In PO13 9, where much of the housing stock dates from the inter-war period, a Level 3 Survey is often the more appropriate choice to uncover the specific issues that affect older brick and render construction in this coastal area.
Prices for Level 3 Surveys in the PO13 9 area typically start from around £600 for smaller properties, with larger or more complex homes costing significantly more. The final price depends on factors such as property size, age, and construction type. Detached properties with extensive roof space and multiple storeys will cost more than a small flat. For a typical three-bedroom semi-detached house in Lee-on-the-Solent, you can expect to pay between £600-£800, while larger detached properties may cost £1,000 or more.
While new build properties may have fewer obvious defects, a Level 3 Survey can still identify issues with construction quality, snagging items, or problems that may not be apparent to an untrained eye. Our surveyors check for defects in workmanship, missing components, and issues that might not be covered by the new home warranty. If the property is a new development in the Gosport area, you might also consider our snagging inspection service which focuses specifically on finishing defects.
The RICS Level 3 Survey focuses primarily on the condition of the property rather than its market value. However, we can provide a valuation as an additional service if you require it for mortgage purposes or to confirm your offer is appropriate for the property's condition. Given the recent market data showing a -0.6% change in average property prices in PO13 9 over the last 12 months, having accurate valuation information is valuable for negotiation purposes.
The on-site inspection typically takes between 2-4 hours, depending on the size and complexity of the property. A large detached house with multiple outbuildings will take longer than a small terraced property. You'll receive your written report within 3-5 working days. For larger properties or those with complex structural issues, we may need additional time to complete a thorough assessment.
Yes, we actively encourage buyers to attend the survey. This gives you the opportunity to see any issues firsthand and ask questions as the inspection progresses. Your surveyor can explain their findings in real-time and point out areas of concern that may require future maintenance. For properties in PO13 9, we particularly recommend attending so you can see first-hand any issues related to the coastal environment or foundation movement.
Our surveyors pay particular attention to several area-specific issues in PO13 9. These include signs of coastal flood damage, foundation movement caused by clay shrink-swell, render degradation from salt air exposure, timber decay in roof structures from prolonged moisture exposure, and corrosion of metal elements. We also check for evidence of previous flooding from Fareham Creek or surface water accumulation in lower-lying streets.
While specific concentrations of listed buildings within PO13 9 require verification with Gosport Borough Council, there are heritage properties in the wider Lee-on-the-Solent area including some listed buildings. If your property is listed or within a conservation area, our survey will note any specific maintenance requirements or restrictions that may apply. We can also advise on whether a more detailed heritage assessment would be appropriate.
