Questions about pipe and tank lagging in Seaham
How soon can you visit a home in Seaham?
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 you cover all of SR7?
Yes, we cover the SR7 postcode district and the districts around Seaham.
Do you take on jobs outside Seaham?
Yes. We also work in Peterlee and Chester-le-Street and elsewhere in County Durham.
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.
