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.

Why book with us in Llandudno
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Fixed written price
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.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Questions about loft insulation for an older house in Llandudno
What do I need to do before you arrive in Llandudno?
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.
Do you cover all of LL30?
Yes, we cover the LL30 postcode district and the districts around Llandudno.
Is loft work in Llandudno 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.
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.
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.
