What is pipe and tank lagging?
We fit a jacket to the top and sides of each tank and foam lagging to every exposed pipe, taped at the joints and bends. The ceiling under the tank is left uninsulated so warmth from below can reach it. More about pipe and tank lagging.

Questions about pipe and tank lagging in Blackwood
How do I pay for work in Blackwood?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Is loft work in Blackwood 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 NP12?
Yes, we cover the NP12 postcode district and the districts around Blackwood.
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.
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.
