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 wet, dirty, matted or full of droppings, laying fresh wool on top just buries the problem, so we say so and price removal instead. More about a loft insulation top-up.

Questions about a loft insulation top-up in Putney

How do I pay for work in Putney?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

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

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 a landlord in Putney book work for a tenanted house?

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

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.
