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 Cambridgeshire

Are your prices the same across Cambridgeshire?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

How do I book a survey in Cambridgeshire?

Send the form or call us. We call back to agree a time and confirm it in writing.

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.
