Questions about sheep's wool or natural loft insulation in Carmarthen
Do you charge extra to travel to Carmarthen?
Not normally. Our guide prices include normal travel to Carmarthen. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
What do I need to do before you arrive in Carmarthen?
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.
How soon can you visit a home in Carmarthen?
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.
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.
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.
