Questions about a loft insulation top-up in Llangefni

Is loft work in Llangefni 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 you cover all of LL77?

Yes, we cover the LL77 postcode district and the districts around Llangefni.

How do I pay for work in Llangefni?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

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.
