Mould problems we see in York
Yorkshire housing stock is a mix of solid-wall terraces, post-war semis and newer airtight builds, and each fails differently. Older York properties tend to suffer cold external walls and mould behind furniture; newer ones trap moisture because they are sealed tight with weak extraction. We measure the room before we tell you which one you have.
Bathrooms and bedrooms make up most of our call-outs, followed by cold north-facing walls, window reveals and unheated box rooms. If it has already come back after a previous clean, that is a sign the cause was never dealt with.
Why mould is common around North Yorkshire
North Yorkshire's enormous variety of housing — from ancient Moors farmhouses to Victorian market town terraces and vale villages — is united by predominantly pre-1940 solid-wall construction with minimal insulation across a county where rainfall exceeds the national average in most locations. The specific mould cause varies considerably between elevated moorland properties, which face penetrating damp, and low-lying vale villages, where rising damp from clay soils and high water tables is the more common finding. The survey process is especially important in North Yorkshire, where making assumptions about cause based on location alone would often lead to incorrect diagnosis and ineffective treatment.

Who we help in York
Tenants and private landlords
Damp and mould complaints in rented York property. We inspect, clean the affected surfaces and set out in writing what is causing it and what will stop it returning, so repairs can be dealt with properly.
Victorian and stone solid-wall homes
Older York terraces and cottages have no cavity to insulate, so external walls stay cold all winter. We deal with the mould and advise on insulation, heating and airflow instead of just painting over it.
Modern and recently renovated homes
New windows, loft insulation and sealed-up draughts trap moisture inside. If extraction is weak or unused, mould appears in bathrooms, bedrooms and wardrobes. We test what the room is doing before recommending ventilation.
15+ years on Yorkshire property
We have worked on the same terraces, semis and rentals for years, so we know how they fail.
Our own technicians
The person who quotes is the person who does the work. Nothing is subcontracted out.
Professional biocides, no bleach
Safe treatments that kill the growth rather than bleaching the colour out of it.
Fixed written price first
You see the price and what is included before we start. No day-rate surprises.
Homes in York and why mould grows
York's historic brick and timber properties near the Ouse and Foss, and its many rentals, holiday lets and shared houses, often have limited airflow. Older buildings were designed to breathe, and modern sealing can trap moisture.
Non-breathable paints and sealed windows in older homes hold moisture in. The right fix is often better airflow rather than stronger chemicals.
