Questions about a loft insulation top-up in Alton

How soon can you visit a home in Alton?

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.

Will I get a written quote for work in Alton?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Can a landlord in Alton book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Which way should the top-up layer run?

Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.

Can I still store things in the loft after a top-up?

Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
