Ventilation installation in Hull
Extractor fans, positive input ventilation and heat recovery systems, fitted to clear damp air from Hull homes.
Hull's terraces were built with open fires, draughty sashes and suspended floors that breathed through air bricks. Decades of improvements have sealed many of them up. Now cooking, showers and washing put moisture into homes that can't easily get rid of it.
Hull at a glance
- Terraced homes
- 46.7% of Hull households live in a terraced house, almost double the share in Leeds. 29.4% live in a semi, 8.4% in a detached house and 11.4% in a purpose-built flat. Source
- Flood history
- On 25 June 2007, 110mm of rain fell on Hull in 24 hours and more than 10,000 properties were damaged across Hull and the East Riding. Hull City Council describes the city as a flat basin of low-lying land below sea level. Source
Air bricks and floors
Many Hull terraces have suspended timber ground floors with air bricks in the front and back walls. If those are blocked by raised paths, paint or debris, the void under the floor gets damp and the joists can rot. Clearing them is free and often makes a noticeable difference.
If the house flooded in 2007 or since, check the air bricks and underfloor void were cleaned and dried properly afterwards.
Fans that clear the room
A bathroom fan should clear steam within minutes. Many older fans are too weak or switch off with the light. A humidity-controlled fan meeting the extract rates in Approved Document F is the reliable fix. Make sure it's ducted outside, not into the loft.
Whole-house systems
Positive input ventilation works well in two-storey houses with a loft and stairwell, which covers most Hull terraces and semis. Heat recovery ventilation suits airtight newer homes or deep retrofits, and needs filters changed regularly.
Ventilation by house type
Victorian and Edwardian terraces off the main roads
The back kitchen and bathroom extension are usually where moisture builds. Good fans there, plus trickle vents in the windows, often do the job.
Interwar and post-war semis and estate houses
A loft-mounted PIV unit pushing air onto the landing suits this layout and helps with bedroom condensation.
Bungalows in the villages around the city
All rooms are on one level, so a PIV unit in the loft can reach most of the house through a central ceiling diffuser.
Areas covered
Engineers who cover Hull work across areas including The Avenues, Newland Park, Hessle, Cottingham, Anlaby, Kirk Ella, Willerby, Sutton-on-Hull, Bransholme and Kingswood.
Questions people in Hull ask
Can a grant pay for ventilation?
The Warm Homes: Local Grant can include ventilation as part of insulation work. Hull City Council and East Riding of Yorkshire Council both have funding.
Will a PIV unit cost much to run?
Very little on its normal fan speed. If it has a heater for cold days, check it can be set to switch off in mild weather.
Should I open windows in winter?
For a few minutes after cooking or showering, yes. Short bursts clear moisture without losing much heat. Leaving windows open all day in winter just cools the walls and can make condensation worse.
