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.

Why book with us in Dereham
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Honest about grants
If you might qualify for funding, we tell you before we quote.

Questions about blown loft insulation in Dereham
Do you cover all of NR19?
Yes, we cover the NR19 postcode district and the districts around Dereham.
Can a landlord in Dereham book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Is loft work in Dereham different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Is it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
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.
