Detailed structural survey for older properties, listed buildings & unusual construction








A RICS Level 3 Building Survey (also known as a Full Structural Survey) is the most comprehensive inspection available for residential properties. If you are purchasing a period property in Ashburton, a building with unusual construction, or a home that shows signs of deterioration, this detailed assessment provides the clarity you need before committing to your purchase.
Our qualified surveyors serve Ashburton and the surrounding Teignbridge area, delivering thorough reports that cover every accessible element of the property. From the roof structure to the foundations, we examine the building's condition systematically, identifying defects, potential future problems, and the urgency of any repairs needed. With average property prices in Ashburton reaching £346,544, investing in a detailed survey protects your significant financial commitment.
We have extensive experience inspecting properties across the Dartmoor fringe, where traditional Devon construction methods combine with age-related deterioration to create specific challenges for buyers. Our team understands how older buildings in this area perform over time, what to look for in properties built with local stone and traditional lime mortar, and which issues most commonly affect homes in the Teignbridge district.

Conservation Area
Ashburton has a large stock of older period homes, and many sit within the town's Conservation Area, designated in 1971. These buildings were put together using methods and materials that are very different from modern practice, so a close inspection really matters. Our surveyors know the common issues that affect older Devon properties, from failing stonework and historic roof structures to the wear that decades of weather can leave on traditional buildings.
Detached property values in Ashburton average £449,365, with terraced homes at £328,143 and semi-detached houses at £312,938. With sums like that on the line, a RICS Level 3 Survey is a sensible safeguard, picking up defects that might otherwise stay hidden until repair bills start to mount. It is especially useful for homes that have been extended or altered over the years, as our inspectors can check whether earlier work meets current standards and whether it has created any structural concerns.
Prices in Ashburton have been moving strongly, rising by 9% over the past year and now sitting 3% above the 2023 peak. That sort of market activity can make buying competitive, so it pays to know exactly what you are taking on. A survey gives you room to negotiate if major defects turn up, which can save thousands in repair costs or give you the chance to ask the vendor to deal with issues before completion.
Because the town sits on the edge of Dartmoor, plenty of properties are on slopes or on older ground that behaves differently from modern building land. Our surveyors understand the way local topography affects a house, from drainage patterns to the stability of older foundations. We have inspected many properties in St. Lawrence Lane, North Street, and the streets around the town centre, so we know how buildings perform in different parts of Ashburton.

Drawing on our experience across the Teignbridge area, we see a handful of problems again and again in Ashburton homes. Stonework deterioration is probably the most frequent, especially in properties built from local limestone or granite. Over time the mortar can break down, leaving gaps, letting in water, and sometimes creating instability where repointing has been done with the wrong cement-based mortar that traps moisture.
Historic roof construction is another point we look at closely. Many older Ashburton properties still have traditional cut timber rafters, often with pegged joints rather than modern nail fixings. Those roofs may have been re-covered several times, sometimes with heavier modern tiles that put extra strain on the original structure. Our inspectors check roof timbers for rot, insect attack, and any stress that could affect the building's weathertightness.
We often come across issues with historic windows and doors in period homes as well. Original joinery in older Ashburton houses may have been altered over time, with secondary glazing fitted or the original sashes replaced by modern units. That can help with heat loss, but it can also bring damp problems if ventilation has been cut back. Our survey looks at every window and door, checking how it opens, how secure it is, and whether there are signs of rot or decay.
Damp and condensation are common in traditional buildings, particularly where solid walls have been used instead of modern cavity construction. In Ashburton, with its fairly high rainfall and close link to Dartmoor, moisture management matters. We look at the condition of any damp proof courses, where they are present, review ventilation provision, and note any signs of penetrating or rising damp that could affect the property's condition or the way you plan to use it.
Ashburton's houses reflect South Devon building traditions, and stone construction is widespread across the town. Many properties use local Devonian limestone or granite, often laid in random rubble courses with variable thickness and pointing quality. That gives the town plenty of character, but it also creates differences in construction quality that our surveyors know to examine carefully.
The older housing stock here usually relies on solid walls rather than modern cavity construction, and wall thicknesses often go beyond 400mm. Those thick walls bring good thermal mass, but they can make insulation and moisture control more difficult. It is important to understand how they perform in situ when judging condition and planning any renovation work.
Many Ashburton homes have historic extensions and alterations, some of them done decades, or even centuries, ago. These may take the form of rear wings, outbuildings converted into accommodation, or single-storey additions. Our Level 3 Survey looks closely at the join between original and later construction, checking for movement, water ingress, or poor ties between different elements. We also consider whether historic alterations needed, or should have needed, building regulation approval.
Ashburton's Conservation Area status means plenty of properties face extra planning controls. Our surveyors know the rules around conservation area consent and listed building consent, and we give clear advice on how those designations may affect your plans for the home. If you are thinking about replacing windows, changing rooflines, or extending the building, we can point out any consent requirements in our report.
Our surveyor visits your Ashburton property and carries out a detailed visual inspection of all accessible areas, including roofs, walls, floors, ceilings, and fixtures. We photograph and record any defects we find, looking at their cause, extent, and likely progression. The inspection normally takes 2-4 hours, depending on the property's size and complexity.
We look at the building's structural integrity, from load-bearing walls and beams to joists and foundations. Our report highlights any signs of movement, subsidence, or structural weakness that could affect stability or lead to expensive repairs. We pay close attention to any historic movement that may have settled down but still influences the condition of the building.
Within five working days of the inspection, you receive your RICS Level 3 report. It sets out clear ratings for each element, colour-coded photographs, technical drawings where relevant, and practical recommendations for any repairs or further investigations needed. The report is written in plain English, so it avoids unnecessary jargon without losing accuracy.
Questions after the report are welcome. Our team is on hand to talk through the findings and explain anything that is unclear. If you need quotes for remedial work, we can also suggest specialist contractors. That support carries on after the report lands, which helps you understand what the issues really mean in practice.
We strongly recommend a RICS Level 3 Survey for homes over 100 years old, properties with visible structural movement, listed buildings, houses that have been heavily altered, and any property where you plan major renovations after purchase. Ashburton's Conservation Area status means many local homes fit that description. If you are buying a period house in the town centre or one of the residential streets running away from the A38, a Level 3 Survey gives the depth of assessment needed to understand the building's true condition.
The RICS Level 3 Building Survey goes well beyond the basic checks of a Level 2 survey. Our report looks at the main structural parts of the property, including walls, floors, ceilings, and the roof structure. We assess doors and windows, inspect visible timbers for damp and rot, and review the condition of plasterwork and internal finishes.
It also covers key building services, such as plumbing, electrical installations, and heating systems, and flags any obvious safety concerns or matters that need professional attention. We examine the property's exposure to environmental risks, although our research did not identify specific local problems with mining subsidence, clay shrink-swell, or flooding in the Ashburton area.
For homes within Ashburton's Conservation Area, our surveyors give extra attention to architectural and historic features that may shape future renovation options. The report explains what work might need conservation area consent or listed building consent, so you understand the planning position before you proceed with the purchase. That level of detail is especially useful for period homes, where alterations can bring significant regulatory requirements.
We also consider the surrounding environment, from ground conditions and vegetation that could affect the building to nearby trees with root systems that may interact with foundations. Ashburton does not have a notable mining past, but we still look for signs of ground instability or unusual settlement patterns that could point to deeper problems.
Our approach to every RICS Level 3 Survey in Ashburton and the wider Teignbridge area is methodical. We combine what we see on site with our knowledge of local building traditions and the defects that often turn up in Devon properties. That local experience is especially useful when we are assessing older houses built using region-specific construction methods.
The survey follows a roof-to-foundations inspection. Where it is safe and accessible, we go into the roof space, check under-floor areas if we can, and examine all visible external elevations. Our inspectors are trained to notice the subtle signs of underlying problems, whether those relate to historic movement, water penetration, or the decay of traditional materials.
Buying in Ashburton often means taking on a home with character and history, but also maintenance responsibilities that are not the same as those found in modern buildings. Our report gives you a clear view of the property's condition, so you can make a confident decision about the purchase. We highlight both urgent repair work and longer-term maintenance, which helps you plan for life in a period property in this historic Devon town.

The Level 3 survey provides a far more detailed structural assessment, examining the property's construction and condition in depth. It looks at any visible or suspected structural movement, reviews the roof structure including hidden elements, assesses extensions or alterations, and gives specific advice on renovation options and conservation considerations for period homes. The Level 3 also sets out much fuller guidance on maintenance needs and likely future costs, which matters a great deal for older properties in Ashburton's Conservation Area where ongoing upkeep is likely to be a major factor.
RICS Level 3 Surveys in the Ashburton area usually start from around £450 for properties under £200,000, with most surveys coming in between £562 and £945. For larger or more complex homes valued over £600,000, fees can reach £1,436 or more. The exact cost depends on the property's size, age, and condition. We give fixed-price quotes based on the individual property, so you know exactly what you will pay before booking. The outlay is modest when set against the value of the home, especially since average prices in Ashburton are above £346,000.
Although it is not a legal requirement, a Level 3 Survey is strongly recommended for homes in Ashburton's Conservation Area. These properties are often older and may have particular restoration needs. The survey sets out what work might need consent and helps you understand any limits that could affect future changes. Many homes in the conservation area retain original features such as stone windows, traditional roofing materials, or historic joinery that need specialist care, and a Level 3 Survey identifies their condition and any problems they may be causing.
On site, the inspection usually takes between 2-4 hours, depending on the property's size and complexity. Bigger detached houses or those with extensive alterations will take longer, while smaller terraced homes can be done more quickly. You normally receive the written report within five working days of the inspection, although we can often move faster if a transaction is on a tight timetable. We know that buying in a competitive market can come with pressure, and we will always try to help with urgent requests where we can.
The survey is a detailed visual inspection of all accessible areas. It cannot see behind walls or under the ground, but it can pick up signs of potential issues that may need further investigation. If we find anything that calls for specialist input, such as possible subsidence or significant structural movement, we will recommend a structural engineer before you proceed. Our experience with properties across the Teignbridge area means we know when symptoms point to a deeper problem, and we always set out the right next steps in the report.
Most mortgage lenders ask for a survey as part of their lending criteria, although they do not set the level you must choose. A RICS Level 3 Survey offers the most detailed assessment, giving your lender added confidence in the property's value and condition. Some lenders may even reduce their valuation requirements when they receive a detailed Level 3 report. Because the survey is so detailed, issues are picked up early, which gives time to sort out concerns before they affect your mortgage offer or the transaction timeline.
If our survey uncovers significant defects, there are several routes open to you depending on the type and seriousness of the issue. You may be able to renegotiate the price to reflect repair costs, ask the vendor to complete specified repairs before completion, or, in some cases, withdraw from the purchase without losing your deposit. We give clear guidance on urgency and approximate cost implications for any problems found, so you can decide how to move forward with confidence.
Any property built before 1900 in Ashburton really ought to be surveyed using the Level 3 format, as these buildings often use construction methods that differ sharply from modern standards and may have picked up several alterations over their lifetime. Listed buildings in the area absolutely need Level 3 assessment because of the specific demands of preserving historic fabric. Properties that have been heavily extended or modified, those showing signs of structural movement, and homes where you plan major renovations after purchase are all strong candidates for this detailed Level 3 inspection.
