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
  • Breathable insulation where it suits the building
  • Chimney breasts and party walls kept clear of combustibles where flues are live

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

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.

Boarding done properly

Storage boards go on loft legs, never straight onto the insulation.

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.

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