Finchley's 1930s housing stock is reaching an age where specific inter-war construction defects become increasingly common. Our building pathology service investigates cavity wall tie failure, concrete deterioration, subsidence and damp in these properties.
We investigate complex defects in inter-war semi-detached and detached houses across Finchley, using specialist testing to identify root causes and recommend cost-effective remediation.
Investigation of cavity wall tie corrosion and failure in inter-war houses, including endoscopic inspection and tie testing.
Assessment of concrete lintel, bay support and other concrete component deterioration common in 1930s construction.
Investigation of structural movement and subsidence on London Clay subsoil, including crack monitoring and drainage assessment.
Accurate diagnosis of damp sources in cavity wall and solid wall construction, avoiding unnecessary remedial treatments.
Original wall ties in 1930s houses corrode over time, causing horizontal cracking and bulging of the outer leaf. We investigate and specify appropriate tie replacement.
Yes, concrete lintels in inter-war houses can deteriorate through carbonation and reinforcement corrosion, causing cracking above windows and doors. We diagnose the extent and specify appropriate repairs.
Yes, parts of Finchley sit on London Clay which is susceptible to seasonal shrinkage, particularly near trees. We investigate structural movement to determine cause and severity.
Yes, cavity wall construction can suffer from cavity bridging, failed cavity trays, penetrating damp through porous render and rising damp through solid ground floors. We diagnose the specific mechanism.
