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.

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

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

Questions about loft ventilation in Swansea

Can a landlord in Swansea book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

How do I pay for work in Swansea?

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

Can you visit Swansea outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

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.
