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 Penzance
What do I need to do before you arrive in Penzance?
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.
Do you charge extra to travel to Penzance?
Not normally. Our guide prices include normal travel to Penzance. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can you visit Penzance 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.
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.
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.
