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.

  • Tank jacket and pipe lagging in the loft
  • Eaves kept clear, with ventilation trays where air could be blocked
  • Cables lifted clear of the insulation where possible

Questions about loft insulation in Horsham

Will I get a written quote for work in Horsham?

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

Can a landlord in Horsham 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 take on jobs outside Horsham?

Yes. We also work in Crawley and Haywards Heath and elsewhere in West Sussex.

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.

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.
