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.

  • Gaps in the existing layer filled
  • Eaves ventilation kept clear

Questions about a loft insulation top-up in Risca

How soon can you visit a home in Risca?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

Do you charge extra to travel to Risca?

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

Do you cover all of NP11?

Yes, we cover the NP11 postcode district and the districts around Risca.

Is it worth topping up 100 mm of loft insulation?

Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.

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.
