What is different about insulating a flat's loft?
In most leasehold flats the loft belongs to the freeholder, so the managing agent or freeholder must agree to the work. We can quote for a single flat or the whole block, and work to the managing agent's access and insurance requirements. More about loft insulation for a flat.
- Fire compartment walls left intact
- Single-flat or whole-block quotes

Why book with us in Chiswick
Photos of the finished loft
You see the work done without climbing the ladder.
Honest about grants
If you might qualify for funding, we tell you before we quote.
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
