What is loft insulation?

We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.

  • Area under the cold water tank left clear so it cannot freeze
  • Cables lifted clear of the insulation where possible
  • Eaves kept clear, with ventilation trays where air could be blocked

Questions about loft insulation in Derby

Can a landlord in Derby book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Do you cover all of DE1?

Yes, we cover the DE1 postcode district and the districts around Derby.

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

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 long does it take to insulate a loft?

Most lofts in houses take a single day. A large bungalow loft, a loft that needs clearing first or one with awkward access can run into a second day.

Do I need to empty my loft first?

The floor needs to be clear for the insulation to go down. If moving things yourself is difficult, tell us at the survey and we can price clearing and putting items back on raised boarding.
