It has been a little while since I last published a blog post, but for good reason. Over recent months, I have been exceptionally busy carrying out RICS Level 3 Building Surveys on traditionally built properties across North Yorkshire and the East Riding of Yorkshire, including projects in Scarborough, Whitby, Bridlington, Malton and Driffield.
There has been a noticeable rise in buyers looking to purchase historic properties, old farmhouses, and traditional rural homes with land and outbuildings. These buildings often offer enormous charm and character, but they also come with significant responsibilities. Many have been altered over decades using inappropriate modern materials, while long-term maintenance has frequently been delayed or overlooked entirely. As a result, understanding the true condition of these properties before purchase is absolutely essential.
One recent example involved a substantial mid-1800s sandstone farmhouse located in the rural village of Mickleby near Whitby. The property comprised a traditional stone-built farmhouse together with attached outbuildings, agricultural structures, and approximately 5.3 acres of land. From first impressions, it was easy to understand why the buyers were attracted to it. The setting was excellent, the views were impressive, and the property clearly had huge potential as a long-term renovation and lifestyle project. However, as is often the case with traditional rural buildings of this age, the defects extended far beyond cosmetic refurbishment.
The property was surveyed as part of a RICS Level 3 Building Survey, which is the most comprehensive survey format available for residential properties and particularly well suited to historic buildings, traditional construction, and properties requiring substantial refurbishment. During the inspection, it became clear that there were significant structural concerns affecting several parts of the building, particularly the gable walls, roof structure, chimneys, and internal floors. Due to the extent of visible movement and distortion, I recommended that the purchasers obtain a further structural appraisal from a Chartered Structural Engineer before making any final commitment to purchase. That recommendation ultimately proved extremely valuable, as the subsequent engineering report confirmed many of the issues identified during the survey and helped clarify the likely causes and scope of remedial works required.
Understanding Traditional Construction
The farmhouse itself was of traditional solid sandstone construction dating from approximately 1840 - 1860. Buildings of this era behave very differently from modern houses. The walls were formed from solid masonry roughly 450–470mm thick, with no cavity walls and no damp proof course. Construction methods relied heavily upon vapour permeable materials such as lime mortar, allowing moisture within the building fabric to evaporate naturally over time. These buildings were never intended to function as sealed modern structures, and problems often arise when inappropriate modern materials are introduced.
This is one of the main reasons why historic buildings frequently develop dampness and deterioration after inappropriate modernisation. Cement mortars, impermeable finishes, injected damp proof courses, and modern gypsum plasters can all interfere with how traditional structures manage moisture.
The Problems with Cement Pointing
One of the most significant issues affecting the farmhouse was the widespread use of cement-based pointing. This is something frequently encountered during Level 3 building surveys of historic properties throughout Whitby, Scarborough, Malton, and many surrounding rural areas. Cement mortar is considerably harder and less vapour permeable than traditional lime mortar.
Rather than allowing moisture to dissipate naturally through the joints, it traps moisture within the stone itself. Over time this can accelerate stone deterioration, increase frost damage, contribute to internal dampness, and create long-term decay within embedded structural timbers.
At this property, the cement pointing had already begun to fail in multiple areas. Joints were cracking, moisture was becoming trapped within the masonry, and sections of sandstone showed visible signs of weathering and deterioration. Internally, the effects were equally apparent, with high moisture levels, deteriorated plaster finishes, damp staining, and decayed joinery visible throughout various rooms.
The survey concluded that comprehensive repointing using suitable vapour-permeable lime mortar would ultimately be required across large areas of the property in order to restore the walls’ ability to manage moisture appropriately. Structural Movement to the Masonry Walls
Structural movement was another key theme throughout both the building survey and the structural engineer’s report. The external walls displayed various forms of distortion, including outward bulging, leaning masonry, cracking around openings, and movement associated with the chimney structures. One gable wall showed significant bulging at the lower level, together with concaving higher up, while attached stable walls displayed notable cracking and separation.
The structural engineer concluded that much of this movement appeared to have occurred gradually over a long period of time rather than representing sudden or progressive collapse. Nevertheless, the level of distortion was significant enough to require substantial structural repair and stabilisation works.
Importantly, the movement did not appear to be attributable to a single isolated cause. Instead, it reflected the cumulative effects of long-term moisture penetration, roof spread, deterioration within chimney flues, historic alterations, and the natural ageing process associated with a building exposed to severe coastal weather conditions for well over a century.
Properties located along the North Yorkshire coastline are routinely exposed to harsh wind-driven rain and elevated moisture levels, and over time this exposure inevitably accelerates the deterioration of masonry, pointing, roofs, and chimneys if maintenance is not carefully managed.
Dampness and Moisture Penetration
Internally, the farmhouse showed very high levels of dampness throughout multiple areas of the property. Damp staining, peeling finishes, deteriorated decorations, and moisture-affected masonry were all evident during inspection. The loft spaces also displayed signs of long-term water ingress, particularly around the chimney areas and gable walls.
Importantly, the dampness affecting the property was not attributable to one isolated defect. Instead, it was the result of multiple interconnected issues acting together over many years. Defective rainwater goods, failed chimney flashings, cement pointing, poor ventilation, defective roof detailing, and long-term maintenance neglect had all contributed to elevated moisture levels throughout the building fabric.
This is extremely common within traditional farmhouses and rural cottages throughout North Yorkshire and the East Riding. Many owners understandably assume dampness requires chemical damp proof injection treatments, when in reality the underlying issue is often poor moisture management within the overall building fabric itself.
In buildings of this type, the correct solution is usually holistic repair using compatible traditional methods and vapour-permeable materials, rather than isolated modern damp-proofing systems.
Roof Structure Defects and Lateral Spread
The roof structure itself presented another significant area of concern. From external inspection, there was clear evidence of undulation to the roof slopes and distortion along the ridge line. Internally, the roof timbers showed signs of long-term deflection, particularly within the timber purlins, which were visibly struggling under load.
The structural engineer noted that the roof lacked adequate restraint at the eaves level, allowing lateral spread to occur over time. Water ingress was also evident within the loft space, particularly around the gable walls and chimney locations, where staining, dampness, and deteriorated mortar were all visible.
The engineering recommendations included strengthening works to improve restraint within the roof structure, together with the possible installation of new timber trusses and additional support arrangements. Steel tie rods between the gables were also suggested as a possible means of improving overall stability.
Importantly, the problems affecting the roof were not simply cosmetic or limited to the coverings themselves. The underlying structural arrangement had become inadequate over time and would require careful upgrading if the building was to remain stable in the long term.
Chimneys and Flue Deterioration
The chimneys also contributed heavily to the deterioration affecting the property. Defective mortar flashings, failed flaunching, poorly capped flues, and weathered masonry were allowing substantial moisture penetration into the structure. Internally, this manifested as damp chimney breasts, staining, and elevated moisture levels within adjacent masonry.
The structural engineer further identified bulging associated with the chimney flues themselves, likely caused by prolonged moisture penetration combined with sulphate attack within the flue construction. Recommended repairs included installation of new flue liners, masonry stitching repairs using stainless steel helical bars, repointing works, and replacement of defective flashings.
Defective chimneys are one of the most underestimated causes of dampness and structural deterioration within older stone properties. Once moisture begins entering redundant or defective flues, the resulting deterioration can continue unnoticed for many years.
Rotten Floors and Timber Decay
One of the most serious internal concerns involved the suspended timber floor within the lounge area. The floor had partially failed due to prolonged dampness and inadequate ventilation beneath the structure. In older properties of this type, timber joists are often built directly into solid masonry walls, making them highly vulnerable to decay where moisture levels remain persistently elevated.
The structural engineer warned that the ends of embedded floor joists and roof timbers were likely to be in poor condition and would require further investigation during refurbishment works.
This type of defect is particularly common within neglected old farmhouses and traditional cottages throughout North Yorkshire and the East Riding. Many owners understandably focus on visible cosmetic improvements while underlying structural moisture problems continue unnoticed for years. By the time floors begin to noticeably slope or fail, deterioration is often already extensive.
A Long-Term Refurbishment Project
Another important aspect of this project was helping the buyers understand the overall scale and nature of the refurbishment they were considering. It became very clear during the survey process that this was not a simple cosmetic renovation. The property represented a substantial long-term project that would require careful budgeting, phased repairs, and realistic expectations regarding timescales and costs.
While the building undoubtedly possessed enormous character and long-term potential, significant investment would be required simply to stabilise and weatherproof the structure before modernisation works could properly begin.
However, despite the extensive defects identified, properties like this can still become exceptional homes when repaired appropriately using compatible traditional methods and materials. In many ways, this is exactly why detailed Level 3 Building Surveys are so valuable. They allow purchasers to make informed decisions based on a realistic understanding of the building’s condition, likely repair requirements, and long-term maintenance obligations.
Projects such as this are rarely straightforward, and buyers can often feel overwhelmed once the scale of repairs becomes clear. At Skyline Property Surveys, we recognise that purchasing and renovating a historic farmhouse is not simply a transaction or a construction project. It is a major life decision and, for many people, the fulfilment of a long-held ambition. Because of that, we aim to support our clients throughout the entire journey, from the initial pre-purchase Level 3 Building Survey through to the eventual renovation and long-term improvement of the property.
Whether that involves helping clients understand structural reports, discussing traditional repair approaches, advising on prioritising works, or simply providing reassurance and guidance during what can sometimes feel like an intimidating process, we are always happy to assist wherever possible. For us, it is genuinely a privilege to play a small part in helping people create a home, restore a historic building, and ultimately build something special for their family’s future.
Why Structural Engineers and Building Surveyors Work Together
This case also highlights the importance of collaboration between Building Surveyors and Structural Engineers when dealing with complex historic buildings. As surveyors, our role is to identify defects, understand likely causes, assess levels of risk, and recognise when additional specialist input is required.
In this instance, the structural engineer’s appraisal provided valuable confirmation regarding the nature of the movement and helped guide the likely stabilisation strategy moving forward.
Having both the Level 3 Building Survey and the structural appraisal allowed the purchasers to proceed with a far clearer understanding of the risks, likely repair costs, and overall scale of the project.
Client Feedback
Following completion of the survey process, the clients kindly left the following review:
“We cannot recommend Rick from Skyline Property Surveys enough, he has gone above and beyond, like a big brother looking out for us every step of the way. He carried out numerous visits to the property with the Level 3 survey we had, and guided us throughout the whole process. Outstanding in his knowledge and support, you will not be disappointed in the service received.”
Reviews like this genuinely mean a great deal, particularly on complex projects involving historic properties where buyers are often navigating unfamiliar structural and maintenance issues for the first time.
RICS Level 3 Building Surveys Across North Yorkshire and East Yorkshire
At Skyline Property Surveys, a significant proportion of our work involves carrying out RICS Level 3 Building Surveys on historic properties, traditional masonry buildings, rural cottages, old farmhouses, smallholdings, and coastal properties throughout Whitby, Scarborough, Bridlington, Malton and Driffield, together with the wider North Yorkshire Moors and East Riding areas.
Traditional buildings require a different approach. Understanding how older structures manage moisture, movement, and weather exposure is essential if repairs are to be successful over the long term. Obtaining the correct professional advice before exchange of contracts can make an enormous difference, particularly where substantial structural repairs or refurbishment works are anticipated.
This case study is based on findings within a RICS Level 3 Building Survey and subsequent structural appraisal relating to a traditional sandstone farmhouse in Mickleby near Whitby.
