What is a loft insulation top-up?

Before we quote we measure the existing layer in several places and check its condition. If it is dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.

Questions about a loft insulation top-up in Dorking

Will I get a written quote for work in Dorking?

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

Can a landlord in Dorking book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Do you cover all of RH4?

Yes, we cover the RH4 postcode district and the districts around Dorking.

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.

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.
