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
  • Cross layer to a total of 270 to 300 mm
  • Depth check and photos before and after

Questions about a loft insulation top-up in Nelson

Will I get a written quote for work in Nelson?

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

Do you cover all of BB9?

Yes, we cover the BB9 postcode district and the districts around Nelson.

Do you take on jobs outside Nelson?

Yes. We also work in Colne and Burnley and elsewhere in Lancashire.

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.
