Compare Damp & Mould Risk
Compare Damp Risk Scores, Victorian solid-wall housing percentages, and energy performance ratings between any two UK postcode districts.
Outcode M1 has a 33 POINT LOWER damp risk score than B11
M1 benefits from a lower concentration of uninsulated solid-wall masonry (13.8% vs 58.6%) and lower rain exposure (Very Severe vs Severe), reducing thermal dew-point condensation.
Housing Stock & Moisture Dynamics: B11 vs M1
When assessing property condition between B11 (Birmingham) and M1 (Manchester), the primary structural differentiator is the age profile of the residential building envelope.
In B11, 64.6% of properties are solid-wall Victorian or Edwardian construction, compared to 10.6% in M1. 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, B11 records 32.7% of properties in EPC bands E through G, while M1 records 5.2%. Colder internal surface temperatures accelerate the condensation of ambient indoor moisture, substantially elevating the risk of black mould spore germination.
