Questions about a loft insulation top-up in Lancaster

Do you cover all of LA1?

Yes, we cover the LA1 postcode district and the districts around Lancaster.

What do I need to do before you arrive in Lancaster?

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.

Will I get a written quote for work in Lancaster?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Can new insulation go on top of old insulation?

Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.

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.
