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
  • Waste packaging removed
  • Eaves kept clear, with ventilation trays where air could be blocked

Questions about loft insulation in Dartford

Do you take on jobs outside Dartford?

Yes. We also work in Swanley and Swanscombe and elsewhere in Kent.

Do you cover all of DA1?

Yes, we cover the DA1 postcode district and the districts around Dartford.

Will I get a written quote for work in Dartford?

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

Will loft insulation make my loft colder?

Yes, and that is expected. The insulation keeps the heat in the rooms below, so the loft above runs closer to the outdoor temperature. That is why pipes and the tank are lagged as part of the job.

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.
