What is loft ventilation?

Most pitched roofs are ventilated at the eaves, sometimes with high-level vents as well. Insulation pushed into the eaves can block that path, which is why we fit ventilation trays. More about loft ventilation.

  • A note of air leaks from the house that need sealing
  • Eaves trays where insulation could block airflow
  • Soffit, tile or ridge vents as specified

Questions about loft ventilation in Chepstow

Is loft work in Chepstow different from anywhere else?

The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

Do you take on jobs outside Chepstow?

Yes. We also work in Monmouth and Newport (Gwent) and elsewhere in Gwent.

How do I pay for work in Chepstow?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

My bathroom fan vents into the loft. Is that a problem?

Yes. It pumps warm, wet air straight into the coldest part of the house. The duct should run to outside through a vent tile, soffit or wall.

Does my loft need ventilation after insulation?

A cold loft needs a path for outside air, usually at the eaves. New insulation must not block it, which is why we fit eaves trays.
