Home ventilation assessment and upgrades
We assess how air moves through the property and plan ventilation improvements that work with the home as a whole.
Signs worth having checked.
- Persistent humidity
- Condensation despite regular heating
- Weak bathroom or kitchen extraction
- Stale air
- Mould after new windows or insulation
The symptom is the starting point.
The same mark can have several causes. We use your description to prepare, then inspect the property before recommending work.
What does a survey include?Checks that put the symptoms in context.
- Existing extract flow and duct routes
- Background air inlets
- Air transfer beneath and around internal doors
- Whether the loft is suitable for PIV
- Combustion appliances and safety constraints
Clear next steps.
- Upgraded extract fans
- Continuous mechanical extract where suitable
- Positive input ventilation
- Improved background ventilation
- Controls and practical user guidance
The recommendation depends on the property and the evidence found during the survey.
What the inspection can and cannot establish.
- Airflow measurements describe conditions at the time of testing and can change with doors, windows, weather and occupancy.
- Ducts, fans, lofts and electrical supplies may need opening-up or another specialist where they cannot be safely inspected.
- Combustion appliances and major alterations may require qualified building-services or building-control advice.
Different properties need different answers.
- Repairing or upgrading intermittent extract in kitchens, bathrooms and utility rooms
- Continuous mechanical extract where the property and duct routes suit it
- PIV or another whole-home approach where the building, loft and air paths make it appropriate
- Improving background vents and door undercuts alongside extraction
Deal with the cause, then the finish.
- Record moisture sources, room use, existing fans, vents and air paths.
- Measure or inspect the relevant extract and check where replacement air can enter.
- Agree the system, controls, duct routes and maintenance access before installation.
- Commission the system, explain controls and review whether moisture conditions improve.
What a quotation or report should make clear.
- The rooms, fans, ducts, controls and electrical work included
- Any making-good, access equipment or loft preparation required
- Commissioning or airflow checks where included
- Filter, fan and cleaning maintenance plus homeowner operating guidance
Small checks help protect the result.
- Keep grilles, filters, trickle vents and air-transfer routes clear.
- Use controls as explained and report unusual noise, weak airflow or persistent condensation.
- Keep service records and arrange cleaning or filter changes at the stated interval.
UK guidance worth keeping.

Ventilation: questions and answers.
Why did condensation start after new windows?
New windows can reduce uncontrolled draughts. If ventilation was not improved at the same time, indoor humidity may rise and condense on the coldest surfaces.
Should extractor fans vent into the loft?
No. Moist air should be ducted to the outside through a suitable route. Discharging it into the loft can simply move the condensation problem upstairs.
Is trickle ventilation enough?
It depends on the property, moisture load and extraction. Background vents are one part of a wider ventilation plan.
