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 St Helens
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.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.

Questions about loft insulation for an older house in St Helens
Is loft work in St Helens 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.
Will I get a written quote for work in St Helens?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
How soon can you visit a home in St Helens?
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.
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.
