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
  • Tank jacket and pipe lagging in the loft
  • Mineral wool to 270 to 300 mm across the whole loft floor

Questions about loft insulation in Chelmsford

Can a landlord in Chelmsford book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

How soon can you visit a home in Chelmsford?

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.

Is loft work in Chelmsford 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.

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.

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.
