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.

  • Gaps in the existing layer filled
  • Depth check and photos before and after
  • Eaves ventilation kept clear

Questions about a loft insulation top-up in Redruth

Will I get a written quote for work in Redruth?

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

Do you take on jobs outside Redruth?

Yes. We also work in Camborne and Truro and elsewhere in Cornwall.

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

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

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.
