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.
- Cables lifted clear of the insulation where possible
- Waste packaging removed
- Mineral wool to 270 to 300 mm across the whole loft floor

Questions about loft insulation in Farnham
Can you visit Farnham outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
How do I pay for work in Farnham?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
How soon can you visit a home in Farnham?
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.
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.
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.
