Thin insulation? If it’s dry and clean, we’ll top it up.

If what you have is in good order but too thin, a new layer across the top is all it needs. We check it’s sound first, so we’re not covering a problem.

About this service

A top-up keeps your existing insulation and adds a second layer across the joists. Before we lay anything, we check the old layer is dry, clean and free of droppings.

What’s included

  • A check that the existing insulation is dry and clean
  • A new layer laid across the joists
  • Eaves kept clear for airflow
  • Cables lifted on top, pipes and tanks lagged
  • Hatch insulated and sealed
  • A written quote first

We price the job after looking at your loft. You get a written quotation before any work is agreed.

When a top-up is right

If you can see the tops of the joists, the insulation is probably too thin. As long as it’s dry, clean and not squashed flat, it can stay and a new layer goes over it.

When it isn’t

If the old insulation is damp, stained, mouldy, full of droppings or crushed by storage, a top-up just buries the problem. We’ll tell you and quote for removal instead.

How we do it

The new layer goes at right angles across the joists, covering the timber and evening out the depth. Eaves stay open and the hatch is sealed.
