What is a loft insulation top-up?
Before we quote we measure the existing layer in several places and check its condition. If it is dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.
- Cross layer to a total of 270 to 300 mm
- Eaves ventilation kept clear

Why book with us in Belfast
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.

We measure before we quote

Questions about a loft insulation top-up in Belfast
Do you charge extra to travel to Belfast?
Not normally. Our guide prices include normal travel to Belfast. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can a landlord in Belfast book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Is loft work in Belfast 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.
Which way should the top-up layer run?
Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
Is it worth topping up 100 mm of loft insulation?
Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.
