Ventilation installation in Bolton
Describe the problem and we pass it to ventilation installers who cover Bolton.
Bolton backs onto the West Pennine Moors, and the weather that rolls off them keeps the town cool and damp for much of the year. Inside, that means walls and windows that stay cold enough for moisture to settle, especially in older terraces with solid walls.
Every household puts several litres of water vapour into the air each day from cooking, showers and drying washing. Ventilation's job is to get it out before it lands on a cold surface.

Start in the wet rooms
A kitchen fan that vents outside and a bathroom fan with an overrun timer or humidistat deal with most moisture at its source. Many older fans are undersized or blocked with dust; replacing them is a quick, cheap win.
Check that any existing bathroom fan actually ducts to the outside. Some only push damp air into the loft, where it causes new problems.
Whole-house options
Positive input ventilation draws air from the loft, filters it and pushes it gently into the landing. The slight pressure forces damp air out through gaps and vents. It suits Bolton's many two-storey semis and terraces with a usable loft.
MVHR (mechanical ventilation with heat recovery) extracts stale air from wet rooms and supplies fresh air to living rooms and bedrooms, recovering most of the heat. It works best in airtight homes, such as new builds or houses after a deep retrofit.
Help with the cost
The GMCA's Warm Homes: Local Grant mainly funds insulation and low-carbon heating in selected areas of Bolton. When insulation makes a home more airtight, installers have to make sure ventilation is adequate too, so it's worth asking about if you're offered work under the scheme.
Bolton homes and what they need
Mill-era brick and stone terraces
Single-storey back kitchens in older terraces often have no mechanical extraction. A through-wall fan above the cooker or sink takes a few hours to fit.
Interwar and post-war semis
A PIV unit fitted in the loft above the landing can dry out bedrooms that suffer from black mould around the windows every winter.
Newer estates on the edges of town
Newer homes in places like Horwich and Westhoughton are built airtight and depend on their fans and trickle vents. Keep vents open and clean fan grilles regularly.
Areas covered
Engineers who cover Bolton work across areas including Farnworth, Horwich, Westhoughton, Little Lever, Kearsley, Astley Bridge, Harwood, Breightmet, Bromley Cross and Egerton.
Questions people in Bolton ask
Will a PIV unit push my heating bills up?
It draws air from the loft, which is usually a little warmer than outside, and many models have a small heater for very cold days. Most households see little change, and a drier home is easier to heat.
Can I fit an extractor fan myself?
Swapping a like-for-like fan is simple, but new fans in bathrooms involve electrical zones that need a qualified electrician.
