Understanding whether a building has been constructed correctly.
Independent investigation of defective workmanship, poor construction quality, failed repairs, non-compliant detailing and building defects. We help clients understand what has gone wrong, why it has occurred and what remedial action may be required.
Not every building defect is caused by age, weather or material deterioration. Many problems arise because work has simply not been carried out correctly.
Defective workmanship can affect new-build developments, refurbishment projects, roof replacements, extensions, heritage repairs and routine maintenance works.
At Strut Building Surveyors, we investigate whether defects arise from poor workmanship, inadequate detailing, inappropriate materials, failure to follow recognised standards or a combination of factors.
Our objective is to provide clear, evidence-based advice that helps clients understand the nature of the defect, the likely cause and the most appropriate route towards resolution.
Clients often instruct Strut when significant expenditure is involved, when previous repairs have failed or where responsibility for defects is disputed.

Understanding how construction defects develop and affect long-term building performance.
Assessment of workmanship affecting roofs, walls, rainwater systems and external fabric.
Independent investigation of poor roofing workmanship and failed repair works.
Defective workmanship occurs when construction, repair or maintenance work falls below the standard reasonably expected of a competent contractor.
This may involve poor installation, inadequate detailing, inappropriate materials, failure to follow manufacturer guidance, non-compliance with recognised standards or simple construction errors.
In some cases, defects become visible immediately. In others, problems may not emerge for months or even years after completion.
Many workmanship defects are discovered only after water ingress, material deterioration, cracking, movement or premature failure becomes apparent.
When significant defects arise, opinions often differ regarding responsibility, causation and appropriate remedial works.
An independent investigation helps establish what has occurred, whether workmanship is likely to be a contributing factor and what corrective action may be required.
Our role is not to advocate for a particular contractor or manufacturer but to provide impartial technical advice based upon evidence and professional judgement.
Incorrect installation of slates, tiles, leadwork, flashings, flat roofing systems, roof ventilation and rainwater goods.
Failures at junctions, parapets, abutments, openings and weathering details that allow moisture ingress.
Assessment of repairs that have not resolved the original issue or have introduced new defects.
Consideration of workmanship against relevant standards, guidance and accepted good practice.
Independent technical assessment where responsibility for defects is contested.
Investigation of hidden defects that only become apparent after a period of occupation or use.
Incorrect fixing, poor detailing, inadequate ventilation, defective flashings and premature roof failure.
Leaks, dampness, condensation-related issues and failed weatherproofing details.
Render defects, masonry deterioration, cladding failures and poor installation practices.
Unsuitable materials, inappropriate repair techniques and loss of historic building performance.
Defects arising during extensions, conversions, retrofit works and major refurbishment schemes.
Independent assessment of workmanship standards and overall quality of completed works.
