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.

  • Depth check and photos before and after

Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

Downlights made safe

Questions about a loft insulation top-up in Bromley

Do you charge extra to travel to Bromley?

Not normally. Our guide prices include normal travel to Bromley. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Can a landlord in Bromley 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 take on jobs outside Bromley?

Yes. We also work in Beckenham and Catford and elsewhere in Greater London.

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.

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.
