Condensation and mould ventilation fixes in Leicestershire

In Leicestershire homes, black mould usually comes down to the same few causes: weak fans, loft-vented ducts and no background ventilation.

Every job in Leicestershire gets a written quote before it starts and a commissioning record when it finishes. We cover Coalville, Wigston Magna, Melton Mowbray, Market Harborough and Oadby and the villages around them.

What the work involves

Mould needs that damp surface to grow. Ventilation is usually the biggest part of the cure, but not the only part. Heating patterns, insulation gaps and cold bridges matter too, and some damp is not condensation at all: leaks, penetrating damp and rising damp need different trades.

Survey and findings

Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.

Fan upgrades

Weak or loft-vented fans replaced and ducted outside, with humidity control.

Whole-home ventilation

PIV, continuous extract or MVHR where moisture is spread through the house.

Questions about condensation and mould ventilation fixes in Leicestershire

Are prices different in Leicestershire?

Our guide prices are adjusted by region. In Leicestershire we use East Midlands rates, so new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £435 to £725 inc VAT per fan.

What is the main cause of condensation in a house?

The main cause is moisture from everyday living, such as showers, cooking and drying clothes, that is not being extracted, combined with cold surfaces where it condenses. Poor or failed extract fans are a very common cause.

Will a dehumidifier fix condensation?

A dehumidifier helps in one room but treats the symptom. Fixing the extract in the wet rooms, and adding whole-home ventilation where needed, removes moisture before it spreads.

Is the survey free in Leicestershire?

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.

Which rules apply to ventilation in Leicestershire?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.

We can log humidity in your Leicestershire home afterwards so you can see the improvement.
