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 Seaham
Can a landlord in Seaham 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 Seaham 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.
How soon can you visit a home in Seaham?
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.
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.
