What is a loft insulation top-up?

Before we quote we measure the existing layer in several places and check its condition. If it is wet, dirty, matted or full of droppings, laying fresh wool on top just buries the problem, so we say so and price removal instead. More about a loft insulation top-up.

Questions about a loft insulation top-up in Derbyshire

Can you quote for several properties in Derbyshire?

Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.

Do you cover the whole of Derbyshire?

Yes. We cover every town and village in Derbyshire, including Derby, Chesterfield and Long Eaton.

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.
