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.

We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Questions about a loft insulation top-up in Clwyd
Are your prices the same across Clwyd?
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.
Do you cover the whole of Clwyd?
Yes. We cover every town and village in Clwyd, including Wrexham, Buckley and Deeside.
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.
