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 second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.
- Waste packaging removed
- Eaves kept clear, with ventilation trays where air could be blocked
- Mineral wool to 270 to 300 mm across the whole loft floor

Dust sheets on the route in and every bit of packaging taken away.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.

Questions about loft insulation in Nailsea
How soon can you visit a home in Nailsea?
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 Nailsea?
Not normally. Our guide prices include normal travel to Nailsea. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
What do I need to do before you arrive in Nailsea?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
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.
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.
