Questions about a loft insulation top-up in Darwen
Do you take on jobs outside Darwen?
Yes. We also work in Blackburn and Haslingden and elsewhere in Lancashire.
Do you cover all of BB3?
Yes, we cover the BB3 postcode district and the districts around Darwen.
Will I get a written quote for work in Darwen?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Can I still store things in the loft after a top-up?
Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
Which way should the top-up layer run?
Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
