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.

  • Cross layer to a total of 270 to 300 mm
  • Eaves ventilation kept clear
  • Gaps in the existing layer filled

Why book with us in Essex

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

Questions about a loft insulation top-up in Essex

Are your prices the same across Essex?

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.

Which council covers my address in Essex?

Councils in Essex include Essex, Southend-on-Sea and Thurrock. Your council matters for building control questions and some funding schemes.

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.
