Home Ventilation installation Northampton
Ventilation installation in Northampton
Fans, positive input ventilation and heat recovery systems, fitted by installers who cover Northampton.
A lot of Northampton's housing went up between the late 1960s and the 1990s. When those homes got double glazing, cavity fill and new doors, they became much more airtight than they were designed to be. The small bathroom fans and trickle vents they started with are often no longer enough.
Newer developments around Upton and the edges of town were built to tighter standards and usually have mechanical ventilation designed in. Keeping it working is the job there.

Estate homes
Start with the fans. Many original bathroom fans are noisy, weak and vent into the loft. A modern humidity-controlled fan ducted to the outside makes a big difference to condensation.
If windows still stream in the mornings, a positive input ventilation unit in the loft can help. It pushes fresh, filtered air into the landing and forces damp air out.
Check the trickle vents in your windows are open. On many estate homes they were closed years ago to stop draughts, which leaves the house with almost no background ventilation.
New builds with MVHR
Mechanical ventilation with heat recovery brings in fresh air and keeps most of the heat. It only works if the filters are cleaned or changed and the unit is set up correctly. Builders don't always commission it well. If rooms feel stuffy, ask an installer to check the airflow rates against Approved Document F.
In a heatwave
Pitsford's 40.2°C in July 2022 shows how hot it can get. MVHR units with a summer bypass stop warming incoming air. PIV units should have a temperature cut-off so they don't push hot loft air into the house.
Northampton homes and what they need
Planned estates and newer developments
Check that kitchen hoods duct outside rather than recirculate. Many on estates don't.
Interwar and postwar semis
A loft above the landing makes PIV straightforward to fit.
Red-brick Victorian terraces
Blocked airbricks under suspended floors cause damp joists. Clear them before adding anything mechanical.
Areas covered
Engineers who cover Northampton work across areas including Abington, Kingsthorpe, Duston, Weston Favell, Far Cotton, Kingsley, Spinney Hill, Upton, Wootton and Moulton.
Questions people in Northampton ask
Does ventilation waste heat?
A little, but a dry house heats more easily than a damp one. MVHR recovers most of the heat it would otherwise lose.
How much does PIV cost to run?
Most loft units draw a similar amount of power to a light bulb. Some have a small heater for winter, which adds to the cost; ask whether you need it.
