Questions about a loft insulation top-up in Bishopston

Will I get a written quote for work in Bishopston?

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

Do you cover all of SA3?

Yes, we cover the SA3 postcode district and the districts around Bishopston.

Is loft work in Bishopston 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.

Can new insulation go on top of old insulation?

Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.

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.
