Questions about sheep's wool or natural loft insulation in Dorchester
Do you take on jobs outside Dorchester?
Yes. We also work in Weymouth and Bridport and elsewhere in Dorset.
Can a landlord in Dorchester book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
What do I need to do before you arrive in Dorchester?
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.
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.
