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.

  • Cross layer to a total of 270 to 300 mm
  • Tank jacket and pipe lagging in the loft

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

Questions about a loft insulation top-up in Crawley

What do I need to do before you arrive in Crawley?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

How do I pay for work in Crawley?

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 Crawley?

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

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.
