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.

  • Cables lifted clear of the insulation where possible
  • Eaves kept clear, with ventilation trays where air could be blocked
  • Mineral wool to 270 to 300 mm across the whole loft floor

Questions about loft insulation in Lewes

How do I pay for work in Lewes?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

Will I get a written quote for work in Lewes?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

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

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.

Does loft insulation need building control approval?

On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
