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.
- Area under the cold water tank left clear so it cannot freeze
- Cables lifted clear of the insulation where possible
- Eaves kept clear, with ventilation trays where air could be blocked

Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.

Questions about loft insulation in Ballycastle
Do you charge extra to travel to Ballycastle?
Not normally. Our guide prices include normal travel to Ballycastle. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Will I get a written quote for work in Ballycastle?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

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.
Does loft insulation need building control approval?
On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.

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.
