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.

Questions about loft insulation for an older house in Johnstone

Can you visit Johnstone 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.

Is loft work in Johnstone different from anywhere else?

The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

How soon can you visit a home in Johnstone?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

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.

What is the best loft insulation for an old house?

Usually a vapour-open material such as sheep's wool or wood fibre, laid so moisture can still move. Mineral wool is also vapour-open and works in many period lofts at lower cost.
