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 Larne
Will I get a written quote for work in Larne?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you cover all of BT40?
Yes, we cover the BT40 postcode district and the districts around Larne.
How soon can you visit a home in Larne?
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.
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.
