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 Penarth
Can you visit Penarth outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Do you charge extra to travel to Penarth?
Not normally. Our guide prices include normal travel to Penarth. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Is loft work in Penarth 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 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.
