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.

Questions about loft insulation in Calne

Do you cover all of SN11?

Do you charge extra to travel to Calne?

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

Is loft work in Calne 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.

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.

Do I need to empty my loft first?

The floor needs to be clear for the insulation to go down. If moving things yourself is difficult, tell us at the survey and we can price clearing and putting items back on raised boarding.
