The most thorough survey available for properties in this historic Northamptonshire village








Our team provides RICS Level 3 Building Surveys across Blakesley and the wider NN12 area. This comprehensive inspection is the gold standard for property assessments, giving you an in-depth understanding of any property's condition before you commit to purchase. looking at a charming period cottage on High Street or a modern family home in this picturesque South Northamptonshire village, our inspectors deliver thorough, unbiased reports that help you make informed decisions.
Blakesley is a distinctive village with a rich architectural heritage, featuring properties built from local marlstone and ironstone dating back several centuries. The village sits on geology that includes Upper Lias Clay, which presents specific challenges for property foundations. Our local surveyors understand these unique characteristics and tailor each inspection to address the particular construction methods and potential issues found in this area. With house prices averaging around £409,000, a detailed Level 3 survey protects your significant investment.
The village itself sits around 122 metres above sea level on the higher ridges where patches of Boulder Clay overlay the Upper Lias Clay beneath. This combination creates particular challenges for foundations, especially during periods of drought or heavy rainfall when the clay soils expand and contract. Our inspectors have extensive experience assessing properties in this part of South Northamptonshire and understand how the local geology affects buildings ranging from Georgian manor houses to the smaller cottages that line the village's historic lanes.

Blakesley's housing stock presents unique considerations that make a RICS Level 3 Survey particularly valuable. The village contains numerous properties constructed from traditional materials including warm orange oolitic marlstone, ironstone, and slate - materials that require specialist knowledge to assess properly. Many homes date from the 17th and 18th centuries, with some Georgian properties featuring characteristic architectural details such as sash windows, flagstone hallways, and oak panelling. These older properties, while full of character, often conceal hidden defects that only an experienced surveyor would detect. Properties along Collswell Lane and the High Street particularly showcase this traditional ironstone construction under slate roofing.
The local geology presents specific structural considerations that directly impact foundation performance. Properties in Blakesley sit atop Upper Lias Clay and Boulder Clay, which are known for their shrink-swell behaviour. This means foundations can move significantly in response to changes in soil moisture - a particular concern during periods of drought or heavy rainfall. Our inspectors are trained to identify signs of this type of movement, including characteristic crack patterns in walls, uneven floors, and doors or windows that no longer close properly. Understanding these local ground conditions is essential when assessing any property in the village, whether it's a modern house or a centuries-old cottage. The British Geological Survey identifies this area as having potential shrink-swell hazard.
The presence of numerous listed buildings in Blakesley adds another layer of complexity for prospective buyers. Properties such as the Church of St Mary (Grade II*), Priory Farmhouse (Grade II*), Barton House on the Green, and many Grade II listed buildings throughout the village require careful assessment. These historically significant properties often have special construction methods and materials that standard surveys may not adequately address. A Level 3 Building Survey provides the detailed analysis needed for these properties, examining both visible conditions and potential hidden issues that could affect structural integrity or require expensive remediation. Additionally, many properties in Blakesley fall within or near conservation area boundaries, which brings specific planning considerations that our surveyors can identify.
Common defects we find in Blakesley properties include damp issues arising from the age of many buildings and their traditional construction methods. Rising damp is frequently encountered where original damp-proof courses are absent or deteriorated, while penetrating damp can result from weathered pointing on the porous marlstone walls. We also regularly identify structural movement related to the reactive clay soils, with crack patterns ranging from vertical stress lines to more concerning stepped fractures that follow mortar joints. Roof problems are another significant finding, particularly on properties with older slate tiles where individual tiles may have slipped or the lead flashing around chimneys has deteriorated. Properties built before 1999 may contain asbestos in older soffits or flooring materials, while those built before 1970 might have lead pipes or lead-based paint in hidden locations.
Prices vary based on property size, age, and condition
Contact us online or by phone to arrange your RICS Level 3 Survey. We'll ask for the property address, approximate age, and size to provide an accurate quote. Once confirmed, we'll arrange a convenient inspection date, typically within 5-7 working days. For properties in Blakesley, we recommend booking as early as possible in your purchase process given the village's popularity and limited survey availability.
Our qualified RICS surveyor visits the Blakesley property to conduct a thorough visual inspection spanning 2-4 hours depending on size. For properties in this area, we pay particular attention to the stonework condition, foundations, roof structure, and any signs of movement related to the local clay geology. We inspect all accessible areas including the roof void, under-floor spaces where accessible, and outbuildings. Our inspector will also note any trees close to the property that might affect foundations through moisture extraction or root intrusion.
Within 5 working days of the inspection, you'll receive your comprehensive RICS Level 3 Building Survey report. This includes clear ratings for each element, photographs of any defects found, and practical recommendations for repairs and maintenance. We highlight any urgent issues requiring immediate attention and provide guidance on estimated costs for significant repairs. For listed buildings, we include specific advice on conservation requirements and any works that might require Listed Building Consent from West Northamptonshire Council.
Given Blakesley's geology with Upper Lias Clay and Boulder Clay, we strongly recommend a Level 3 Survey even for newer properties. The shrink-swell risk in this area can affect properties of any age, and early identification of foundation movement can save thousands in future repair costs. If the property has mature trees nearby or has undergone significant landscaping, this is particularly important. The drainage patterns across the parish, with streams feeding into the River Tove tributary, can also affect ground conditions in lower-lying areas.
Properties in Blakesley showcase various construction methods that reflect the village's long history. Georgian and earlier properties typically feature solid walls built with lime mortar rather than modern cement, which allows the building to 'breathe' - an important characteristic that surveyors must understand. These traditional buildings may have shallow foundations compared to modern standards, making them more susceptible to movement in the reactive clay soils found throughout the parish. Our inspectors assess how these traditional elements interact with the property's overall structural integrity and identify any inappropriate modern repairs that might compromise the building's breathability.
The roofing on Blakesley properties ranges from traditional slate to more modern tiles, with older properties potentially featuring stone or slate tiles that require specialist assessment. Many historic homes have open fireplaces and chimneys that may show signs of deterioration or require inspection for safe use. Properties along Old School Lane and the properties near the Bartholomew Arms pub particularly showcase these traditional features. The combination of age, traditional materials, and local environmental factors means each property requires an individual assessment approach. We bring local knowledge of how these buildings have performed over time and what common issues to expect in this specific area.
Modern developments in the wider NN12 area, including those in nearby Towcester such as The Watlings and The Furlongs, may feature different construction types including cavity wall builds and more recent methods. Even these newer properties benefit from Level 3 Survey assessment, as our inspectors can identify any construction defects, inadequate specifications, or issues arising from the local ground conditions. The thoroughness of a Building Survey provides whatever type of property you're considering purchasing in this area. With recent planning applications for developments in the surrounding area having been refused, Blakesley retains its village character with properties that predominantly date from before 1900.

A Level 3 Survey provides a comprehensive assessment of all accessible parts of the property. In Blakesley, this includes detailed inspection of the marlstone or ironstone walls, foundations (particularly important given the local clay geology), roof structure, floors, walls, ceilings, doors, windows, chimneys, and bathrooms. The report provides specific ratings for each element, identifies defects, explains their implications, and recommends appropriate repairs or further investigations. We also assess any outbuildings, boundaries, and the overall site drainage that might be affected by the local geology.
Prices for RICS Level 3 Surveys in Blakesley typically start from around £900 for a smaller property, rising to £1,200-£1,500 for standard family homes, and £1,500 or more for larger period properties or those with complex structural issues. The exact cost depends on the property's size, age, and condition. Given the age of housing stock in Blakesley with many properties dating from the 17th and 18th centuries, most properties will fall into the higher price brackets. The presence of local marlstone and ironstone construction also requires specialist assessment expertise.
If you're purchasing a listed building in Blakesley - and there are over 12 listed properties including several Grade II* buildings such as the Church of St Mary and Priory Farmhouse - a Level 3 Survey is strongly recommended. These properties have special architectural and historic interest that requires detailed assessment beyond what a standard survey provides. The survey will identify works required to maintain the building properly and highlight any alterations that might affect its listed status. We also provide guidance on what works might require Listed Building Consent from West Northamptonshire Council, which is essential given the stricter planning controls in place for historic properties.
Yes, our surveyors are trained to identify signs of subsidence and ground movement, which is particularly relevant in Blakesley due to the local Upper Lias Clay and Boulder Clay geology. The survey will look for characteristic crack patterns, check if doors and windows operate properly, assess the condition of foundations where visible, and evaluate external factors such as trees or drainage that might affect ground stability. We specifically examine the relationship between nearby trees and the property, as tree roots can extract moisture from clay soils causing seasonal movement. Where concerns are identified, we recommend appropriate specialist investigation such as a structural engineer's report or ground investigation.
A Level 3 Survey in Blakesley typically takes between 2-4 hours depending on the property size and complexity. Smaller cottages on the High Street may take closer to 2 hours, while larger period properties with extensive outbuildings or complex histories may require longer inspection times. We'll advise you of the expected duration when booking. You'll receive your detailed report within 5 working days of the inspection, with urgent issues flagged immediately upon completion of the site visit.
If our survey identifies significant issues, the report will clearly explain the problem, its cause, and recommended actions. This might range from obtaining specialist quotes for repairs to negotiating with the seller to reduce the purchase price or have them address specific issues before completion. For properties with foundation movement related to the clay soils, we can recommend structural engineers who specialize in this type of work in the Northamptonshire area. The detailed nature of the Level 3 report gives you strong leverage in these negotiations and helps you budget appropriately for any remedial work needed after purchase.
While Blakesley is not located directly on a main river, the parish is drained by several streams that join an east-flowing tributary of the River Tove on the southern boundary. Properties in lower-lying areas or those near watercourses may have some surface water flood risk, particularly during periods of heavy rainfall. Our surveyors note the position of watercourses relative to the property and assess any existing drainage systems. We can advise on whether the property has any history of flooding and whether appropriate flood resilience measures might be worth considering.
Period properties in Blakesley commonly face several specific issues we identify during surveys. The traditional lime mortar pointing on marlstone and ironstone walls often deteriorates over time, allowing moisture penetration. Many properties have original single-glazed sash windows that may be rotten or inefficient. The solid floor constructions in older cottages can lack proper damp-proof membranes, leading to damp issues. We also commonly find outdated electrical wiring and plumbing that doesn't meet current standards, which may require updating for modern living while respecting the property's character. The presence of asbestos in older materials and potential lead paint in pre-1970s properties is also assessed.
