Condensation and mould ventilation fixes in Middlesbrough
We find why the house is wet and fix the ventilation, rather than painting over mould. Covering Middlesbrough and TS1, TS2 and TS4.
- From £420 inc VAT per fan
- Free survey

In Middlesbrough homes, black mould usually comes down to the same few causes: weak fans, loft-vented ducts and no background ventilation.
We cover Middlesbrough and the surrounding TS1, TS2 and TS4 postcodes as part of our work across North Yorkshire. Surveys for new installations are free on the UK mainland, with a written quote afterwards.

Questions from Middlesbrough
Is the survey free in Middlesbrough?
For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
Is black mould dangerous?
Damp and mould can affect health, particularly for people with asthma, allergies, weak immune systems, children and older people, according to NHS and government guidance. It should be dealt with rather than lived with.
Is PIV or MVHR better for condensation?
For most existing homes with general condensation, PIV plus good extract fans is the most cost-effective fix. MVHR suits airtight, well-insulated homes and full renovations.
