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.

Fixed written price

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

Tank and pipes protected

Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

Questions about loft insulation in East Sussex

Do you cover the whole of East Sussex?

Yes. We cover every town and village in East Sussex, including Brighton, Eastbourne and Hastings.

Can you quote for several properties in East Sussex?

Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.

How deep should loft insulation be?

The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target 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.
