Questions about pipe and tank lagging in Portstewart
Will I get a written quote for work in Portstewart?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Is loft work in Portstewart 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.
Can a landlord in Portstewart book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
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.
