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 dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.

Questions about a loft insulation top-up in Dunbartonshire

Do you cover the whole of Dunbartonshire?

Yes. We cover every town and village in Dunbartonshire, including Bearsden, Clydebank and Vale of Leven.

Which council covers my address in Dunbartonshire?

Councils in Dunbartonshire include East Dunbartonshire and West Dunbartonshire. Your council matters for building control questions and some funding schemes.

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.
