Old loft insulation removal

Loft insulation removal means bagging and clearing the existing insulation so the loft floor can be inspected, cleaned and re-insulated. It is needed when the old layer is wet, contaminated by droppings, smoke or a leak, badly compressed, or hiding a problem that has to be seen.

What is old loft insulation removal?

Our team wears coveralls and respirators, works from crawl boards and bags the old material in heavy-duty sacks. The bags are taken away for disposal. With the joists clear, we can check the ceiling, the wiring and the timber before laying new insulation. Most jobs are removal and replacement together, quoted as one.

Is it right for your loft?

  • The insulation is wet or has dried after a roof leak
  • Rodent or bird droppings, or a past infestation
  • Smoke or fire damage
  • It is flattened under old boards or by years of use

How we do it

  1. We inspect and photograph the insulation and agree what goes.
  2. The route through the house and the landing are sheeted.
  3. Old insulation is bagged and taken out through the hatch.
  4. The loft floor is cleared and the ceiling, wiring and joists checked.
  5. New insulation is laid to full depth.

What is included

  • Bagging and removal of the old insulation
  • Disposal

Worth knowing

If there is any chance the old material contains asbestos, such as vermiculite loose fill, it must not be disturbed until it has been tested. Licensed removal is a specialist job and we will not touch it.
