What is loft insulation?

We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.

  • Mineral wool to 270 to 300 mm across the whole loft floor
  • Eaves kept clear, with ventilation trays where air could be blocked
  • Waste packaging removed

Questions about loft insulation in Johnstone

Will I get a written quote for work in Johnstone?

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

Do you charge extra to travel to Johnstone?

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

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

How long does it take to insulate a loft?

Most lofts in houses take a single day. A large bungalow loft, a loft that needs clearing first or one with awkward access can run into a second day.

Does loft insulation need building control approval?

On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
