Before buying a house or flat, a technical inspection helps compare its visible condition with the information available. In Madeira, coastal exposure, sloping sites and wind-driven rain warrant particular attention to façades, roofs, drainage and retaining walls.
Cracking, distortion and structural corrosion
Diagonal cracks around openings, distorted floors or spalling concrete with exposed reinforcement require technical interpretation. A crack may reflect shrinkage in a finish or structural movement: its width alone cannot establish the cause.
The inspection records the location, pattern and context of defects. Suspected settlement or significant corrosion may warrant monitoring, opening-up works or a dedicated structural assessment. A visual inspection cannot certify the safety of concealed elements.
Damp: identifying likely sources and extent
Staining, salt deposits, mould and blistering paint can indicate rainwater ingress, plumbing leaks or condensation. In a north-facing bedroom, mould may relate to cold surfaces and inadequate ventilation; near a roof, waterproofing, flashings and drainage need checking.
Moisture readings and thermal imaging can help locate anomalies, but results depend on environmental conditions and do not, by themselves, establish where water originates. Recent redecoration and a visit during dry weather can conceal significant evidence.
Building services and safe use
Accessible water, drainage and electrical components are examined alongside ventilation and hot water provision. Leaks, slow drainage, exposed wiring or improvised alterations justify specialist investigation.
Electrical testing, gas inspections and pressure or leak testing require appropriate procedures and qualified personnel. They should be commissioned where necessary: visual observations are not equivalent to certification of the installations.
Alterations and Portuguese planning requirements
The property should be checked against approved drawings, applicable planning and use authorisations, the land registry certificate and the property tax record. Enclosed balconies, extensions, converted lofts and changes of use deserve scrutiny. Neither registration nor tax records alone establish planning compliance.
Portugal’s RJUE, established by Decree-Law No. 555/99, as amended, governs development control. Assessment also depends on municipal rules and the regime applicable when work was undertaken. Exemption from presenting certain documents at completion of the sale does not legalise unauthorised work.
The report and the purchase decision
The report should identify inspected areas, access restrictions, photographs, defects and priorities. It should distinguish observations from possible explanations and specify further investigations. Repair estimates need explicit assumptions and are neither contractors’ quotations nor a property valuation.
Before entering a binding commitment, arrange access to critical areas and resolve documentary uncertainties. Use the findings to weigh up repairs, negotiate terms and decide whether further testing is needed before purchase.
