What is a loft insulation top-up?

Questions about a loft insulation top-up in Sandown

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

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

Will I get a written quote for work in Sandown?

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

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

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 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.
