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.

Why book with us in Tenby
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.

Questions about pipe and tank lagging in Tenby
What do I need to do before you arrive in Tenby?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
Is loft work in Tenby 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.
How soon can you visit a home in Tenby?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
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.
Is pipe lagging included with loft insulation?
Yes. A tank jacket and pipe lagging in the loft are included in every loft insulation and top-up price. If you only need lagging, it is priced on its own.
