About this service

We lay a layer of insulation between the ceiling joists and a second across them, keep the eaves clear for ventilation, lift cables on top and lag pipes and tanks. Anything wrong in the loft is put right first.

What’s included

  • A loft check before anything is laid
  • Any damp, old insulation or pests dealt with first
  • Insulation between the joists and a layer across them
  • Eaves kept clear with trays where needed
  • Pipes and tanks lagged, cables lifted on top
  • Hatch insulated and draught-sealed

We price the job after looking at your loft. You get a written quotation before any work is agreed.

Right way round

Plenty of lofts get insulated on top of a problem: damp timber, soiled insulation, blocked eaves. The new layer then hides it until it shows through the ceiling. We check the loft first and fix what we find, so the insulation stays dry and does its job.

How we lay it

The first layer fills the space between the ceiling joists. The second goes across them, so the timber doesn’t become a cold line. Insulation always stays on the loft floor. The only thing we ever fix to the rafters is thin foil insulation, where a room in the roof calls for it.

The details that matter

Eaves trays keep a path for air at the edges. Cables sit on top so they stay cool. Pipes and the water tank above the new layer are lagged, because the loft will be colder. And the hatch is insulated and sealed, because it’s the easiest gap to miss.

Loft insulation: your questions answered

How deep should it be?
For mineral wool, around 270 mm is commonly recommended. We’ll say what we suggest for your loft in the quote.
Can you insulate over my existing insulation?
If it’s dry and clean, yes, that’s a top-up. If it’s damp, dirty or soiled, it should come out first.
Can I still store things up there?
Yes, with a raised storage floor above the insulation.
Is the work guaranteed?
Eligible installations come with a guarantee of up to 5 years. Your written quote says whether your job qualifies and what it covers.
