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

Can you visit Swansea outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

What do I need to do before you arrive in Swansea?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Can a landlord in Swansea book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

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.
