What is different about insulating an older home's loft?

We work from crawl boards spanning several joists so the ceilings are not loaded, check for loose plaster keys before anything is laid, and usually recommend vapour-open insulation such as sheep's wool or wood fibre. Unfelted slate roofs are naturally well ventilated, but they let in wind-driven rain and snow, which the insulation has to cope with. More about loft insulation for an older house.

  • Ceiling-safe working from crawl boards
  • Chimney breasts and party walls kept clear of combustibles where flues are live
  • Breathable insulation where it suits the building

Why book with us in Devon

Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Tidy work

Dust sheets on the route in and every bit of packaging taken away.

Tank and pipes protected

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

Questions about loft insulation for an older house in Devon

Are your prices the same across Devon?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

Do you cover the whole of Devon?

Yes. We cover every town and village in Devon, including Plymouth, Exeter and Paignton.

Do I need permission to insulate a listed building's loft?

Possibly. Listed building consent is needed for works that affect the building's character. Ask your council's conservation officer.

Can loft insulation damage lath-and-plaster ceilings?

It can if people kneel between joists or if the ceiling is already weak. We work from boards and check the ceiling first.
