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

Questions about loft insulation for an older house in Colwyn Bay

Do you charge extra to travel to Colwyn Bay?

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

Will I get a written quote for work in Colwyn Bay?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Is loft work in Colwyn Bay 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.

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.
