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.

  • Depth check and photos before and after
  • Gaps in the existing layer filled
  • Eaves ventilation kept clear

Questions about a loft insulation top-up in Brecon

Do you charge extra to travel to Brecon?

Not normally. Our guide prices include normal travel to Brecon. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Do you take on jobs outside Brecon?

Yes. We also work in Builth Wells and Ystradgynlais and elsewhere in Powys.

Will I get a written quote for work in Brecon?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

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.
