Ventilation installation in Wolverhampton

How to tell if you need more ventilation

Windows that stream every morning, a musty smell in bedrooms and black spots in the corners of ceilings are the classic signs. A cheap hygrometer helps: indoor humidity that sits above about 60% for long periods in winter usually means moisture isn't getting out.

Before buying a system, check the basics. Are trickle vents open, do fans work, and is washing dried indoors without a window open? Fixing those costs little.

Positive input ventilation in semis

With almost half of Wolverhampton households in a semi, PIV is one of the most useful fixes here. A unit in the loft feeds filtered air into the landing, raising air pressure slightly and pushing damp air out through vents and gaps.

It works best alongside working extractor fans in the kitchen and bathroom.

Extractor fans to Part F

In Wolverhampton homes, kitchens and bathrooms need fans that meet the extract rates in Approved Document F. Old fans often fall short or exhaust into the loft rather than outside. A good installer measures airflow and checks the ducting.

Humidity-controlled fans run until the room dries out, which helps in busy family homes.

Kitchen hoods that only recirculate through a filter catch grease but leave the steam in the room. If yours doesn't duct outside, a wall fan near the cooker is the cheap fix.

Mechanical ventilation with heat recovery suits new builds and major renovations, where ducts can be installed while ceilings and floors are open. In an occupied home, fans and PIV are usually more practical.
