Comprehensive structural assessments for Glasgow's tenements, Victorian villas, and properties with subsidence or movement concerns








Glasgow's property market faces unique structural challenges: over 30 coal mines operated within or close to the city boundaries during the early 20th century, and at least 77,000 homes date from before 1919, built using porous Carboniferous sandstone that suffers from weathering, delamination, and moisture-related decay. A 2019 Glasgow City Council study estimated that repairing the city's ageing tenement stock could cost up to £2.9 billion. If you are buying a property showing signs of structural movement — cracks in walls, uneven floors, sticking doors — or purchasing an older tenement on Glasgow's boulder clay subsoil, a dedicated Structural Survey provides the in-depth engineering assessment you need to understand the extent of any defects and the cost of repair before you commit.

Glasgow sits on the edge of the historic Lanarkshire coalfield, and documented mining activity beneath areas including Rutherglen, Cambuslang, Castlemilk, and parts of the city's southern and eastern fringes creates potential ground stability risks that manifest as structural movement decades or even centuries after mines closed. When underground coal seams were worked, ground water levels dropped due to pumping. Once mining ceased and pumps were switched off, water levels recovered, causing the ground to lift slightly — a process known as rebound uplift. This can crack foundations, distort door frames, and cause characteristic stepped cracking in masonry walls. Our structural assessment identifies movement patterns consistent with mining subsidence and recommends further specialist investigation where necessary, including Coal Authority searches and engineer assessments.
Separate from mining concerns, Glasgow's housing stock is dominated by sandstone tenements built between 1850 and 1914. The city's builders used locally quarried blonde Carboniferous sandstone from Giffnock and Bishopbriggs, along with red sandstone imported from Dumfriesshire. Both stone types are porous and absorb water, which leads to freeze-thaw damage during cold winters. Over the years, well-intentioned repairs using hard cement mortar have sealed the stone surface, trapping moisture inside and accelerating decay. This inspection examines sandstone facing for delamination — where the outer layers peel away in sheets — and identifies whether inappropriate cement pointing has created hidden structural damage behind the visible stonework. These defects can cost thousands of pounds per elevation to repair using traditional lime mortar and stone replacement.
Glasgow tenements also share structural vulnerabilities specific to their construction method. Floor joists bear into pockets in the external sandstone walls. If moisture penetrates the wall — from failed guttering, defective downpipes, or rising damp — the joist ends rot, reducing their load-bearing capacity. Over time, this causes the external wall to bulge outward, creating a dangerous structural defect that requires evacuation, temporary shoring, and expensive remedial work involving lifting floors and inserting new steel ties. Our surveyors inspect accessible joist bearing points, check for telltale bulging on external elevations, and assess whether shared building elements like roofs and gutters are contributing to moisture ingress. These detailed assessments go beyond the scope of a standard RICS Level 2 or Level 3 survey, providing engineering-level insight into structural integrity.

At least 30 coal mines operated within or on the edge of Glasgow during the early 20th century, including workings beneath Rutherglen, Cambuslang, Castlemilk, and other southern and eastern districts. A 2018 British Geological Survey study noted that while Glasgow was largely stable from satellite monitoring in the 1990s, much of the city's mining ended before 1950 — meaning ground water recovery and associated uplift occurred before satellite data became available. Local press reports document recent subsidence events causing cracks in buildings, and the majority of these incidents are associated with phenomena occurring over a short spatial scale. Specialist surveyors examine crack patterns, floor levels, and door alignment for signs of ground movement, and recommend Coal Authority searches and specialist geotechnical investigation where subsidence is suspected.

Prices based on a typical 2-3 bed Glasgow tenement flat. Structural Survey costs increase with property size, complexity, and extent of visible defects. Glasgow prices reflect Scottish market rates, which run below the national average.
The structural engineers and RICS surveyors we work with in Glasgow have direct experience assessing properties on the city's glacial boulder clay subsoil, identifying mining-related subsidence in areas bordering the Lanarkshire coalfield, and diagnosing the early stages of joist-end rot before tenement walls bulge dangerously. They understand the difference between normal settlement cracks and those caused by ground movement, recognise when cement repairs have trapped moisture behind sandstone, and can advise on whether structural defects require immediate remedial work or long-term monitoring. They are based locally across Glasgow and typically inspect properties within days of booking.

Enter the property details — address, type, approximate age, and number of bedrooms. Mention any visible structural concerns such as cracks, uneven floors, or sticking doors. You'll receive a price straight away. If a Structural Survey is appropriate, you can book and pay online. We'll contact the seller or their agent within 24 hours to arrange access.
A qualified structural engineer or RICS surveyor visits the property. On a typical Glasgow tenement flat with visible defects, expect the inspection to take 4-6 hours. The surveyor examines crack patterns, checks floor levels for unevenness, inspects accessible foundation areas, assesses joist bearing points in external walls, and examines sandstone elevations for delamination and weathering. Larger properties — such as West End villas or four-storey townhouses — may take longer.
You receive a detailed structural report within 5-7 working days. It includes a technical assessment of defects identified, an explanation of likely causes (mining subsidence, settlement, moisture-related decay), recommendations for further specialist investigation if needed, and estimated repair costs where possible. Our team can arrange follow-up Coal Authority searches, geotechnical engineer inspections, or timber decay specialists based on the report findings.
Glasgow sits on glacial boulder clay deposited during the last ice age, forming the distinctive drumlin hills visible across the city — from the Necropolis to Queen's Park. This clay subsoil is prone to shrinkage when it dries out, particularly during prolonged dry periods or when mature trees draw moisture from the surrounding ground. Properties built on clay can experience foundation settlement, causing cracks in walls, uneven floors, and distortion of door and window openings. Detailed assessment of crack patterns and floor levels helps determine whether settlement is historic and stable or ongoing and progressive, helping you understand whether the property requires underpinning, tree management, or simply monitoring over time.
Glasgow's built environment was shaped by the city's rapid industrialisation in the 19th century. As workers flooded into the city to support shipbuilding, engineering, and manufacturing along the Clyde, developers constructed dense grids of sandstone tenements to house them. These buildings were erected quickly using local blonde Carboniferous sandstone from quarries at Giffnock, Bishopbriggs, and Overwood in Lanarkshire, along with red sandstone imported from Dumfriesshire for grander West End terraces. The variation in stone quality, construction standards, and subsequent maintenance means that two outwardly similar tenements on the same street can be in vastly different structural condition. Many tenements also incorporated embedded iron and steel fixings to support bay windows and decorative stonework — fixings that are now rusting due to Glasgow's wet climate, causing cracking and movement in the surrounding masonry.
Beneath the surface, Glasgow's industrial past created another structural concern: coal mining. The Lanarkshire coalfield extended into the city's southern and eastern boundaries, and at least 30 mines operated beneath or adjacent to residential areas during the late 19th and early 20th centuries. Mining lowered ground water levels through pumping, causing the ground surface to drop. When mining ceased and pumps were switched off, water levels recovered, and the ground rebounded upward. This process can cause foundation cracking, wall movement, and stepped cracking in brickwork or stonework — defects that appear decades after mining ended. Expert investigation examines these movement patterns and distinguishes between mining subsidence, settlement on boulder clay, and other structural defects, giving you a clear understanding of the property's condition and the likely repair costs involved.

Glasgow's average property price currently sits at £230,000, up 7.4% over the past year. At £470, the Structural Survey represents around 0.2% of that purchase price — a small fraction compared to the cost of structural repairs discovered after completion. Underpinning a tenement flat affected by mining subsidence typically costs £15,000-£25,000. Replacing rotten floor joists that have caused wall bulging can run to £10,000-£18,000 per flat. Re-pointing an entire tenement elevation with traditional lime mortar and replacing damaged sandstone can cost £8,000-£15,000. The survey identifies these issues before you buy, giving you the information to renegotiate the price, request that repairs are completed before settlement, or walk away entirely.
Glasgow's property transaction system requires sellers to provide a Home Report before marketing, which includes a single survey and valuation. However, the Home Report survey is conducted on behalf of the seller, not the buyer. If you have concerns about structural movement — cracks in walls, uneven floors, sticking doors — or you are buying an older tenement in an area with known mining activity, commissioning your own independent Structural Survey gives you a buyer-focused engineering assessment. This is especially relevant in Glasgow where the competitive offers-over system can pressure buyers into quick decisions without full knowledge of a property's structural condition.

Expect to pay from around £470 for a Structural Survey on a standard Glasgow tenement flat. Prices increase with property size, complexity, and the extent of visible structural defects. Larger properties such as a West End villa or a four-bedroom semi-detached house typically cost £600-£900. Properties showing significant structural movement or those in areas with documented mining subsidence may require additional specialist investigation, which is quoted separately. Glasgow prices tend to run below the national average (from £550) due to Scottish market rates.
The Home Report is a useful starting point, but it is commissioned by the seller and designed to facilitate the sale. It includes a single survey with condition ratings, but it does not provide the engineering-level structural analysis that a dedicated Structural Survey offers. For Glasgow properties showing signs of structural movement — such as cracks in walls, uneven floors, or sticking doors — or properties in areas with known mining activity beneath them, a buyer-commissioned Structural Survey gives you an independent assessment focused entirely on protecting your interests. This is especially relevant when the Home Report flags condition ratings of 2 or 3 on structural elements.
On a two- or three-bedroom Glasgow tenement flat with visible structural concerns, the on-site inspection takes 4-6 hours. The surveyor or structural engineer needs to examine crack patterns, check floor levels for unevenness, inspect accessible foundation areas, assess joist bearing points in external walls, and examine sandstone elevations for delamination and weathering. Larger or more complex properties — such as converted villas in Hyndland or townhouses in the Park district — may take 6-8 hours. The written structural report follows within 5-7 working days after the inspection.
Yes. At least 30 coal mines operated within or on the edge of Glasgow during the early 20th century, including workings beneath Rutherglen, Cambuslang, Castlemilk, and parts of the city's southern and eastern fringes. Our inspection examines crack patterns, floor levels, and structural alignment for signs of ground movement consistent with mining subsidence. Surveyors look for characteristic stepped cracking in masonry, distortion of door and window openings, and uneven floor levels. If mining subsidence is suspected, the report will recommend a Coal Authority search to confirm the location of historic mine workings, and may suggest further specialist geotechnical investigation to assess ground stability and recommend remedial measures.
Glasgow's tenements were built using blonde Carboniferous sandstone from local quarries at Giffnock and Bishopbriggs, along with red sandstone from Dumfriesshire. Both types are porous and absorb water, which causes problems over time. Specialist inspection checks for delamination — where the stone face peels away in layers — as well as cracking, erosion on exposed elevations, and damage caused by inappropriate cement repairs. Hard cement mortar used in past decades traps moisture inside the stone, leading to accelerated freeze-thaw decay that can be expensive to reverse. Surveyors also examine rusting embedded iron and steel fixings used to support bay windows, which can crack the surrounding stonework as they corrode.
Professional assessment covers accessible communal areas including the close (stairwell), shared roof void, external walls, and guttering where relevant to assessing structural condition. Under the Tenements (Scotland) Act 2004, repair costs for common parts are shared between flat owners, so the condition of these elements directly affects your financial obligations as an owner. Survey reports flag communal structural concerns — such as wall bulging, roof timber decay, or failed guttering causing moisture ingress — and give you an idea of what collective maintenance or remedial works may be required, helping you budget beyond just the purchase price of your individual flat.
Yes. Glasgow sits on glacial boulder clay deposited during the last ice age, forming the distinctive drumlin hills across the city. This clay subsoil can shrink when it dries out, particularly during prolonged dry periods or when mature trees draw moisture from the surrounding ground. Properties built on clay can experience foundation settlement, causing cracks in walls and uneven floors. Qualified engineers assess crack patterns and floor levels to determine whether settlement is historic and stable or ongoing and progressive. They can advise on whether the property requires underpinning, tree management, or simply long-term monitoring, and may recommend further geotechnical investigation if ground conditions are uncertain.
If significant structural defects are identified — such as progressive subsidence, wall bulging due to joist rot, or extensive sandstone delamination — the report will include recommendations for specialist follow-up investigations and estimated repair costs where possible. You can use this information to renegotiate the purchase price with the seller, request that repairs are completed before settlement, or withdraw from the purchase entirely. In Glasgow's tenement market, survey findings about shared building elements can also inform discussions with other flat owners about coordinating and funding communal structural repairs under the Tenements (Scotland) Act 2004.
