Questions about pipe and tank lagging in Portsmouth

How soon can you visit a home in Portsmouth?

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.

Will I get a written quote for work in Portsmouth?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Can a landlord in Portsmouth book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

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.
