Questions about pipe and tank lagging in Gwent

Are your prices the same across Gwent?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

Do you cover the whole of Gwent?

Yes. We cover every town and village in Gwent, including Newport (Gwent), Cwmbran and Pontypool.

Should I insulate under the water tank in the loft?

No. Leave the ceiling directly under the tank uninsulated so a little warmth from the house reaches it. Insulate the top and sides instead.

Do I need a lid on my cold water tank?

Yes. A close-fitting lid keeps debris and insects out and is part of the water regulations for cold water storage.
