Questions about sheep's wool or natural loft insulation in Grantham
What do I need to do before you arrive in Grantham?
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.
Can you visit Grantham outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Do you cover all of NG31?
Yes, we cover the NG31 postcode district and the districts around Grantham.
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.
