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.
- Waste packaging removed
- Cables lifted clear of the insulation where possible

Questions about loft insulation in Portishead
Can a landlord in Portishead book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do you cover all of BS20?
Yes, we cover the BS20 postcode district and the districts around Portishead.
What do I need to do before you arrive in Portishead?
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.
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.
How deep should loft insulation be?
The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target for your address on the quote.
