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
  • Cross layer to a total of 270 to 300 mm

Questions about a loft insulation top-up in Johnstone

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

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.

Do you charge extra to travel to Johnstone?

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

Do you cover all of PA5?

Yes, we cover the PA5 postcode district and the districts around Johnstone.

Can new insulation go on top of old insulation?

Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.

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.
