Compare Damp & Mould Risk
Compare Damp Risk Scores, Victorian solid-wall housing percentages, and energy performance ratings between any two UK postcode districts.
Outcode B13 has a 1 POINT LOWER damp risk score than M21
B13 benefits from a lower concentration of uninsulated solid-wall masonry (35.4% vs 39.8%) and lower rain exposure (Moderate vs Very Severe), reducing thermal dew-point condensation.
Housing Stock & Moisture Dynamics: B13 vs M21
When assessing property condition between B13 (Birmingham) and M21 (Manchester), the primary structural differentiator is the age profile of the residential building envelope.
In B13, 36.6% of properties are solid-wall Victorian or Edwardian construction, compared to 41.9% in M21. Solid brick masonry lacks the modern thermal break of a cavity wall, resulting in higher moisture permeation through mortar beds during prolonged wet weather.
Regarding energy efficiency, B13 records 25.1% of properties in EPC bands E through G, while M21 records 18.9%. Colder internal surface temperatures accelerate the condensation of ambient indoor moisture, substantially elevating the risk of black mould spore germination.
