Questions about sheep's wool or natural loft insulation in Cardiff
Will I get a written quote for work in Cardiff?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you cover all of CF10?

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.
Do moths eat sheep's wool insulation?
Insulation-grade sheep's wool is treated against insects. We use products sold for loft insulation, not raw fleece.
How deep does natural insulation need to be?
It depends on the product's thermal conductivity. Some need slightly more depth than mineral wool to reach the same U-value, which we allow for on the quote.
