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.

  • Tank jacket and pipe lagging in the loft
  • Gaps in the existing layer filled

Questions about a loft insulation top-up in Dereham

How do I pay for work in Dereham?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

Do you charge extra to travel to Dereham?

Not normally. Our guide prices include normal travel to Dereham. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Do you cover all of NR19?

Yes, we cover the NR19 postcode district and the districts around Dereham.

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.

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.
