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

Questions about loft ventilation in Morden

Do you cover all of SM4?

Yes, we cover the SM4 postcode district and the districts around Morden.

Will I get a written quote for work in Morden?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

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.

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.
