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.

Questions about a loft insulation top-up in Blyth

Do you cover all of NE24?

Yes, we cover the NE24 postcode district and the districts around Blyth.

Will I get a written quote for work in Blyth?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Is loft work in Blyth 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.

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.

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.
