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 Chelsea

Can you visit Chelsea 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.

Do you charge extra to travel to Chelsea?

Not normally. Our guide prices include normal travel to Chelsea. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Will I get a written quote for work in Chelsea?

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

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.
