Damp and moisture service

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.

When to call

Signs worth having checked.

  • Persistent humidity
  • Condensation despite regular heating
  • Weak bathroom or kitchen extraction
  • Stale air
  • Mould after new windows or insulation
Worth knowing: A powerful fan will not work well without a sensible route for replacement air. Ventilation needs to be planned as a whole-house system.
How we assess it

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?
What we look at

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
What may follow

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.

Common questions

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.
