What is sheep's wool or natural loft insulation?
Sheep's wool and wood fibre are vapour-open and can take up and release moisture. The trade-off is cost: natural materials usually cost two to three times as much as mineral wool for the same performance. More about sheep's wool or natural loft insulation.

Why book with us in Mitcham
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Honest about grants
If you might qualify for funding, we tell you before we quote.
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.
