Comprehensive structural survey for Cornish properties - identify defects before you buy








A RICS Level 3 Survey is the most comprehensive property inspection available in the UK, and it's particularly valuable for buyers looking at properties in the TR17 0 area. Marazion, with its rich history as an ancient market town and stunning coastal position overlooking St Michael's Mount, boasts a diverse housing stock that includes period cottages, Victorian terraces, and modern developments. Given the age and character of many properties in this area, a detailed structural assessment can reveal issues that might not be apparent during a casual viewing.
Our team of RICS-registered surveyors in Cornwall understand the specific challenges that coastal properties face. From salt-related erosion to damp penetration in traditional stone-built homes, we know what to look for when inspecting properties in the Marazion area. The Level 3 survey provides you with a thorough analysis of the property's condition, helping you make an informed decision before committing to what is likely to be one of the largest purchases you will ever make.
Properties in Marazion present unique surveying challenges due to the town's historic character and coastal environment. Many homes in the area date back to the 18th and 19th centuries, constructed using traditional Cornish building methods that differ significantly from modern construction. The proximity to Mount's Bay means that properties are exposed to prevailing south-westerly winds and salt-laden air, which can accelerate the deterioration of external building elements. Our surveyors have inspected hundreds of properties throughout the TR17 area and understand how these local factors affect building condition.
Whether you are considering a cottage near The Square, a Victorian terrace along Fore Street, or a modern home in one of the newer developments, our Level 3 survey provides the detailed assessment you need. The comprehensive nature of this inspection makes it particularly suitable for the older properties that dominate the Marazion housing market, where hidden defects can otherwise catch unwary buyers out.

Marazion's unique position on the Cornwall coast means that properties here face specific challenges that our surveyors encounter regularly. The proximity to Mount's Bay brings exposure to salty sea air, which can accelerate weathering of external surfaces and cause corrosion of metal elements. Many properties in the area are constructed using traditional Cornish building methods, including granite and killas slate, which require expert knowledge to assess properly. A Level 3 survey goes beyond the surface-level inspection of a Level 2 survey, delving into the structural elements of the property to identify any underlying issues that could prove costly to rectify.
The housing stock in TR17 0 spans multiple eras, from historic cottages near The Square to more modern developments. Properties built before 1919 are particularly common in this ancient market town, and these older buildings often require more detailed assessment due to their construction methods and the likelihood of historic alterations. Our inspectors have extensive experience evaluating period properties across Cornwall and understand how to identify the tell-tale signs of structural movement, damp ingress, and timber deterioration that affect older buildings in coastal areas.
Recent market data shows significant price variation within TR17 0, with properties ranging from around £170,000 in some postcode sectors to over £500,000 for premium locations near the seafront. This variance reflects the diversity of the local housing stock, which includes everything from modest terraces to substantial detached homes. Regardless of the property value, a Level 3 survey provides essential insight into the true condition of the building, helping buyers budget accurately for any necessary repairs or improvements.
Cornwall's mining heritage also affects properties throughout the region, including those in the TR17 0 area. While Marazion itself is not in a high-risk mining zone, properties across Cornwall can be affected by historic mining activity, with potential for ground instability in some locations. Our surveyors are experienced in identifying signs of mining-related subsidence or movement, which is particularly important for buyers considering older properties that may have been affected by historic ground conditions.

We will ask you to complete a brief questionnaire about the property, including any known alterations, previous damp treatments, or structural works. This helps our surveyor focus on areas of particular concern during the inspection. Please also provide any previous survey reports or building regulation completion certificates if available, as these give valuable context about the property's history.
Our surveyor will systematically examine the external fabric of the property, including roofs, chimneys, walls, foundations, and drainage. In Marazion, particular attention is paid to the condition of slate roofing, stone pointing, and any signs of coastal weathering or salt damage. We will assess the condition of gutters and downpipes, examine any retaining walls or boundary structures, and note the general condition of the property's surroundings including any nearby trees or drainage systems.
The survey includes a thorough internal assessment covering all accessible areas. This includes checking walls for dampness, examining floor structures, assessing the condition of windows and doors, and evaluating the structural integrity of any extensions or alterations. Our surveyor will probe suspected decay in timber elements, assess the condition of any visible damp-proof courses, and check the operation of windows and doors. In older properties, we pay particular attention to any exposed timber frames, original floorboards, and feature fireplaces.
Within a few days of the survey, you will receive a comprehensive report detailing our findings. The report includes clear ratings for each element, photographic evidence of any defects, and practical recommendations for repairs and maintenance. We provide prioritised recommendations so you can understand which issues require immediate attention and which can be planned for over time. The report also includes an executive summary specifically written for conveyancing purposes.
Properties in Marazion face unique environmental challenges that our surveyors are trained to identify. The coastal location means that salt-laden air can cause accelerated deterioration of external renders, metal fixtures, and roof coverings. Our Level 3 survey specifically addresses these coastal factors, examining properties for signs of salt crystallisation in stonework, corrosion of lead or steel elements, and any erosion of mortar joints that could indicate ongoing weathering. We inspect roof pitches from ground level where safe access allows, looking for slipped or broken slates that are common in exposed coastal positions.
The flood risk associated with Mount's Bay is another important consideration for buyers. While properties in TR17 0 are not typically subject to severe flooding, the coastal position means that surface water drainage and the condition of any sea walls or retaining structures should be assessed. Our surveyors will evaluate the property's vulnerability to water ingress and provide guidance on any flood resilience measures that may be appropriate. We also assess the gradient of the surrounding land and the effectiveness of existing drainage systems, which is particularly important for properties on lower-lying ground near the bay.
Properties in elevated positions above Marazion benefit from views but may be exposed to stronger winds. Our surveyors assess the condition of roof coverings, chimneys, and any exposed timber elements that can be affected by wind-driven rain. The combination of exposure and age means that many properties in the area will have some degree of repair need identified during the survey, which is exactly why the detailed Level 3 assessment is so valuable for buyers in this area.

If the property you are purchasing is a listed building or located within a Marazion conservation area, a Level 3 survey is strongly recommended. These properties often have specific planning constraints and may require specialist assessment of historic building elements. Our surveyors understand the requirements for traditional buildings and can identify issues that could affect your ability to make alterations in the future. Many properties in Marazion's historic core will be either listed or within conservation areas, so always check with your conveyancer before proceeding with any purchase.
Based on our experience surveying properties throughout the TR17 area, several recurring issues affect local homes. Dampness is perhaps the most common problem, particularly in older properties with solid walls that lack modern damp-proof courses. The coastal climate can exacerbate damp problems, as driving rain penetrates porous stonework and renders. Our surveyors use specialist equipment to assess moisture levels and identify the source of any dampness, distinguishing between penetrating damp, rising damp, and condensation. This distinction is crucial, as each type requires different remediation approaches.
Timber defects are another significant concern in the area. Traditional Cornish properties often feature timber-framed construction, original wooden floorboards, and exposed beams. These elements can be affected by woodworm infestation, wet rot, or dry rot, particularly in areas where dampness is present. Our Level 3 survey includes thorough assessment of all accessible timber elements, with recommendations for any necessary treatment or repair. We inspect floor voids where accessible and examine any exposed timber in roof spaces, looking for signs of active infestation or historical damage.
Roofing issues frequently feature in our survey reports for Marazion properties. The traditional slate roofs found on many period homes can suffer from cracked or slipped slates, deteriorated leadwork, and problems with ridge tiles. Our surveyors inspect roofs from both inside and outside where accessible, assessing the overall condition and identifying any immediate repairs that may be required. Chimney stacks are also carefully examined, as these are particularly vulnerable to weathering in exposed coastal locations. Many chimneys in the area will have been repointed or had lead flashing renewed, but our surveyors can identify where these repairs are showing signs of age or failure.
Structural movement is occasionally identified in properties throughout the TR17 0 area, particularly in older buildings that have settled over many decades. While some minor movement is normal in period properties, our surveyors can identify concerning patterns that may indicate ongoing subsidence or structural weakness. We examine walls for cracking, assess the alignment of doors and windows, and look for signs of movement in the property's foundations. Properties built on the slopes above Marazion may have specific considerations related to ground stability that our surveyors are experienced in assessing.
A Level 3 survey provides a much more detailed assessment of the property's structure and condition. While a Level 2 survey gives a visual overview of accessible areas, the Level 3 includes in-depth analysis of structural elements, identification of underlying causes of defects, and specific recommendations for repairs. The report is typically two to three times longer and includes guidance on priority of works needed. For properties in Marazion with their age and coastal exposure, this deeper analysis is particularly valuable as it can identify hidden defects that a basic survey might miss.
For properties in the Marazion area, a RICS Level 3 survey typically starts from around £900 for smaller properties. For larger homes or those with complex construction, prices can range up to £1,500 or more. The exact cost depends on factors such as property size, age, and construction type. Given the average property prices in TR17 0, this represents a small percentage of the purchase price but provides invaluable insight. For properties valued over £500,000, which are common near the seafront in Marazion, we recommend budgeting toward the higher end of this range to ensure a thorough inspection.
While modern properties may be adequately covered by a Level 2 survey, a Level 3 is still recommended if the property is particularly large, has been extensively modified, or shows any signs of structural movement or defects. Many buyers in TR17 0 opt for the Level 3 survey for added reassurance, given that even newer properties in the area may have been built with traditional materials that require expert assessment. Additionally, some modern developments in the area may have been built on sites with challenging ground conditions that warrant the deeper investigation that a Level 3 provides.
The duration of a Level 3 survey depends on the size and complexity of the property. For a typical three-bedroom house in the Marazion area, you should expect the inspection to take between two and four hours. Larger properties or those with complex layouts may require additional time. Our surveyor will spend sufficient time to conduct a thorough assessment, examining all accessible areas and elements of the property. We never rush inspections, particularly for older properties where the additional time can reveal issues that would otherwise be missed.
Yes, we actively encourage buyers to attend the survey where possible. This provides an opportunity to point out any specific concerns you may have noticed and to see any issues firsthand as they are identified. Your surveyor can explain their findings in real-time and answer any questions you may have about the property's condition. Walking around the property with our surveyor gives you a much better understanding of the issues identified and the recommended next steps. For buyers who are unable to attend, we can arrange a video call during the survey so you can still see any issues as they are discovered.
If significant issues are identified, the survey report will provide detailed information about the defect, its likely cause, and recommended next steps. This may include obtaining specialist reports for issues such as subsidence or timber infestation. In many cases, you can use the survey results to renegotiate the purchase price with the seller to reflect the cost of necessary repairs. Our report is written in clear language that you can share with your solicitor and any contractors you may subsequently engage, making it easier to understand exactly what work is required and why.
