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.

  • Cables lifted clear of the insulation where possible
  • Eaves kept clear, with ventilation trays where air could be blocked
  • Area under the cold water tank left clear so it cannot freeze

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

We measure before we quote

Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Questions about loft insulation in Blackwood

How do I pay for work in Blackwood?

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

Is loft work in Blackwood different from anywhere else?

The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

Do you charge extra to travel to Blackwood?

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

Can you insulate around downlights?

Recessed downlights need clearance or a fire-rated cover so they do not overheat. We fit covers where needed and leave a clear zone around fittings that cannot be covered.

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.
