Investigating defects. Diagnosing causes. Defining practical solutions.
Independent building surveyors specialising in building pathology, roof and building-envelope failures, moisture-related defects, traditional construction and complex defect investigation. We help clients understand why buildings fail before significant money is committed to repair.
Many surveyors identify defects. Many contractors recommend repairs. Strut focuses on understanding causes.
Our approach combines building surveying, practical construction knowledge and building pathology. We consider how materials, detailing, workmanship, moisture, ventilation, movement and previous alterations interact before forming a technical opinion.
A damp wall, leaking roof or cracked finish is rarely useful as a diagnosis in itself. The important questions are where the failure originated, why it occurred, what else may have been affected and what constitutes a proportionate repair.
This approach is particularly valuable for water ingress, roof failures, condensation, moisture movement, historic buildings, defective workmanship, failed repairs and technically complex refurbishment projects.
Where instructed, our involvement can continue beyond the initial report through repair strategy, specification writing, tendering, contractor procurement, contract administration and technical review of the completed works.
Clients appoint Strut when they require independent technical advice before committing to substantial expenditure or where previous attempts to resolve a building problem have not succeeded.

Evidence-led investigation into how and why buildings deteriorate, leak, move or fail.
Practical understanding of roofs, envelopes, refurbishment, repair and the way construction performs in service.
Technical recommendations based upon evidence, causation, proportionality and long-term building performance.
Building pathology is the systematic investigation of building defects and deterioration. It considers the relationship between construction methods, materials, workmanship, moisture, environmental exposure, building use and previous intervention.
At Strut Building Surveyors, this diagnostic approach sits at the centre of many instructions. Rather than simply recording the visible symptom, we consider the wider building and seek to establish the most credible mechanism of failure.
For example, an internal damp patch may originate from a roof defect, chimney saturation, failed pointing, defective rainwater goods, condensation, a plumbing leak or a moisture pathway some distance from where staining finally becomes visible.
Similarly, a leaking roof may not require wholesale replacement. A small number of failed junctions may be responsible. Equally, repeated local repairs can become poor value where the wider covering has reached the end of its serviceable life.
Our role is to distinguish between these circumstances and provide clients with a reasoned basis for deciding what to do next.
This methodology is particularly relevant to roof condition surveys, specific defect investigations and building-envelope surveys.
We gather evidence before forming conclusions. This can include visible defects, photographs, moisture patterns, material condition, construction details, previous repairs and information provided by the client.
We consider the construction and available evidence to establish the most credible cause or combination of causes. Where certainty is not possible without further investigation, that limitation is made clear.
We translate technical findings into clear written advice, identifying the defect, likely cause, significance, potential consequences and recommended next step.
Where required, we can help move from diagnosis to action through repair strategy, specifications, tendering, contractor engagement and project support.
Clear reporting is central to the Strut approach. Our reports are prepared using InstaSurv™, a structured digital reporting platform designed to organise inspection evidence, defects, photographs, conclusions and recommendations consistently.
The technology supports the reporting process, but professional judgement remains central. The purpose is not simply to produce more information; it is to make technical findings easier for clients and other professionals to understand and act upon.
Clients typically instruct Strut where the problem requires more than a generic condition report.
They may be dealing with a recurring roof leak, persistent dampness, unexplained condensation, cracking, defective workmanship, a failed refurbishment, a difficult acquisition or a historic building where standard repair advice may be inappropriate.
Many instructions arise after previous repair attempts have failed. In these circumstances, repeating another repair without revisiting the diagnosis can simply add cost without resolving the underlying problem.
Our role is to reduce uncertainty and provide clients with an evidence-led basis for deciding whether to repair, investigate further, monitor, redesign or replace.
Investigation of causation rather than simply recording visible symptoms, with recommendations proportionate to the evidence available.
Assessment of pitched and flat roofs, chimneys, leadwork, junctions, rainwater systems, external walls and other elements responsible for protecting the building from weather.
Investigation of water ingress, dampness, mould, ventilation, condensation and moisture movement within modern and traditional construction.
Independent assessment of workmanship, detailing and construction against the project requirements, relevant guidance and applicable technical standards where appropriate.
Advice informed by traditional construction, compatible materials, moisture behaviour and conservation principles.
Identification of defects, maintenance liabilities, areas requiring further investigation and potential future capital expenditure before acquisition.
Technical support from initial investigation through repair strategy, specification, tendering and project delivery where instructed.
Advice focused on the client’s interests rather than the sale of a particular remedial product or contracting solution.
Our reporting process is designed to move from observation through analysis to recommendation. Findings are supported by photographs and clear commentary so the reader can understand what has been observed, what it may indicate and why the issue matters.
Where causation can reasonably be established, we explain the likely mechanism of failure. Where uncertainty remains, we identify what further inspection, testing or specialist input may be required rather than offering unjustified certainty.
This is particularly important for roof failures, moisture ingress, defective workmanship and historic construction, where the visible symptom often represents only part of the wider problem.
A Strut report is intended to support decision-making beyond the date of inspection. Depending upon the instruction, findings may be used by property owners, contractors, solicitors, insurers, managing agents or other professional advisers.
Where further work is required, the diagnosis can form the basis of a repair scope, technical specification or tender package so that contractors are pricing a defined problem rather than interpreting a vague request to “fix the leak” or “resolve the damp”.
This continuity from investigation into repair strategy can reduce ambiguity, improve tender comparison and help ensure that the proposed work addresses the underlying defect.
Where appropriate, Strut can support a building problem beyond the initial survey and report. The scope is tailored to the instruction and may extend into repair design, procurement and project delivery.
Inspect the building, understand its construction and gather evidence about the defect, condition and surrounding circumstances.
Assess likely causation, considering detailing, materials, workmanship, moisture pathways, movement and previous interventions.
Translate the diagnosis into proportionate repair recommendations, schedules of work or technical specifications where required.
Assist clients in obtaining and comparing contractor proposals against a consistent scope of work.
Where appointed, provide contract administration, periodic inspection and technical review as remedial or refurbishment work progresses.
Review completed work, identify outstanding matters and advise on future maintenance or monitoring where appropriate.
Strut provides building surveying services across residential, commercial and historic property, with particular emphasis on instructions where detailed technical understanding and building pathology are required.
Many building failures cannot be properly understood through a standard checklist alone. The construction, materials, interfaces and history of the building need to be considered together.
Based in York, Strut Building Surveyors undertakes building pathology, defect investigation and building consultancy instructions throughout Yorkshire and, where the nature of the instruction justifies it, further afield.
Our work is particularly suited to situations where the cause of a defect is unclear, previous remedial work has failed, significant repair expenditure is being considered or the building requires a more specialist understanding of construction and material behaviour.
If you require independent advice on a roof failure, moisture problem, defective construction, commercial acquisition, listed building, refurbishment scheme or technically complex building defect, we can advise on the appropriate scope of investigation.
Request Building Pathology Advice
Buildings rarely fail for only one reason. Good surveying requires the construction, materials, environment, previous interventions and visible evidence to be considered together.
Strut Building Surveyors combines building surveying with practical construction knowledge and building pathology to help clients understand defects before deciding how to repair them.
From roof failures and moisture ingress to historic buildings, commercial acquisitions and refurbishment projects, our advice is independent, evidence-led and focused on proportionate solutions.
