Questions about pipe and tank lagging in Cardiff
Is loft work in Cardiff 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 take on jobs outside Cardiff?
Yes. We also work in Penarth and Trowbridge (South Glamorgan) and elsewhere in South Glamorgan.
How do I pay for work in Cardiff?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
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.
