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 Cowbridge
Do you take on jobs outside Cowbridge?
Yes. We also work in Llantwit Major and Barry and elsewhere in South Glamorgan.
Do you charge extra to travel to Cowbridge?
Not normally. Our guide prices include normal travel to Cowbridge. 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 Cowbridge?
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.
Is it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
Is blown insulation better than rolls?
It performs about the same for the same depth. It is the faster and neater option in lofts that are awkward to work in, and rolls are better where you want boarding later.
