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 Leicestershire

Which council covers my address in Leicestershire?

Councils in Leicestershire include Leicester and Leicestershire. Your council matters for building control questions and some funding schemes.

How do I book a survey in Leicestershire?

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

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.
