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.

Not normally. Our guide prices include normal travel to Horsham. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

How do I pay for work in Horsham?

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.

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.
