Questions about sheep's wool or natural loft insulation in Caernarfon
How do I pay for work in Caernarfon?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you take on jobs outside Caernarfon?
Yes. We also work in Llangefni and Bangor (Gwynedd) and elsewhere in Gwynedd.
Will I get a written quote for work in Caernarfon?

Is sheep's wool insulation worth the extra cost?
In an older breathable house, or if you care about the material, often yes. In a modern semi with plasterboard ceilings the extra cost buys little performance.
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.
