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
  • A note of air leaks from the house that need sealing
  • Soffit, tile or ridge vents as specified

Questions about loft ventilation in Llanelli

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

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

Do you charge extra to travel to Llanelli?

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

What do I need to do before you arrive in Llanelli?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

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.

Will extra vents make my house colder?

No. The vents ventilate the loft above the insulation, not the rooms below.
