Questions about blown loft insulation in Magherafelt
Can a landlord in Magherafelt 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 Magherafelt?
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.
Do you charge extra to travel to Magherafelt?
Not normally. Our guide prices include normal travel to Magherafelt. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
