What is blown loft insulation?
The machine stays outside or on the landing and the hose runs up to the loft. We hold a board or tray at the eaves so the loose fill cannot block the ventilation path. More about blown loft insulation.

Questions about blown loft insulation in Llangefni
Can a landlord in Llangefni 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 soon can you visit a home in Llangefni?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
How do I pay for work in Llangefni?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Does blown insulation settle?
Mineral wool loose fill settles a little, which is allowed for in the depth we install. The depth markers let you check it later.
Is it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
