Older homes in Worcester often have solid brick or stone walls, meaning they lack the cavity gap modern buildings rely on to prevent moisture transfer. While these walls are durable, they can easily become cold and trap moisture — creating the perfect environment for condensation and mould.
🌬️ Why Solid Walls Suffer from Condensation
Without a cavity, solid walls get colder on the inside during winter. When warm indoor air hits these cold surfaces, it cools rapidly and releases moisture as condensation. Over time, this can cause black mould, peeling paint, and damage to plasterwork.
🧩 Insulation and Ventilation – The Key Balance
The most effective way to prevent condensation is to balance insulation and ventilation:
-
Internal wall insulation: Using breathable, vapour-open systems prevents condensation build-up within the wall itself.
-
Ventilation upgrades: Installing DMEV or PIV units ensures stale, humid air is replaced with filtered, drier air — reducing condensation and improving indoor air quality.
-
Heating control: Keeping rooms consistently warm helps maintain stable surface temperatures and prevents dew-point formation.
🧱 Breathable Materials Matter
Non-breathable paints and plasters trap moisture in solid walls. That’s why Weather Wise Solutions uses breathable systems and products supplied by PAM Ties, ensuring moisture can evaporate safely rather than becoming trapped behind finishes.
