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.

Fire-rated covers or a clear zone around recessed lights.
Honest about grants
If you might qualify for funding, we tell you before we quote.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

Questions about loft insulation in Woolwich
Do you cover all of SE18?
Yes, we cover the SE18 postcode district and the districts around Woolwich.
How do I pay for work in Woolwich?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Is loft work in Woolwich 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 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.
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.
