Compare Damp & Mould Risk
Compare Damp Risk Scores, Victorian solid-wall housing percentages, and energy performance ratings between any two UK postcode districts.
Outcode B1 has a 6 POINT LOWER damp risk score than M1
B1 benefits from a lower concentration of uninsulated solid-wall masonry (6.4% vs 13.8%) and lower rain exposure (Moderate vs Very Severe), reducing thermal dew-point condensation.
Housing Stock & Moisture Dynamics: B1 vs M1
When assessing property condition between B1 (Birmingham) and M1 (Manchester), the primary structural differentiator is the age profile of the residential building envelope.
In B1, 1.7% 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, B1 records 3.8% 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.
