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 Wymondham

Will I get a written quote for work in Wymondham?

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

Can you visit Wymondham outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

Do you cover all of NR18?

Yes, we cover the NR18 postcode district and the districts around Wymondham.

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.

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.
