Plumbing Services

From leak repairs to full re-piping, the same plumbers see the job through from quote to completion — not a rotating cast of subcontractors.

Plumbing Services by GML Construction in North London

Plumbing that matches a property's actual pipework

Period properties across Hampstead and Highgate often have a mix of old lead, copper and more recent plastic pipework, sometimes all in the same house. Working on this safely and effectively means understanding what's actually there before starting, not assuming a modern layout.

Whether it's a single leak or a full re-pipe as part of a wider renovation, we assess the existing system properly before quoting rather than guess at scope.

What's included

  • Leak detection and repair
  • Full and partial re-piping
  • Pressure and flow issues on older systems
  • Boiler and heating system pipework
  • Emergency call-outs for burst pipes

Plumbing as part of bathroom and kitchen projects

Most of our plumbing work happens alongside kitchen and bathroom installations, where we're already opening up walls and floors. If you're planning either, it's worth having us assess the wider plumbing system at the same time rather than treat it as a separate job later.

Common questions

Do you offer emergency plumbing call-outs?

Yes, for burst pipes and active leaks we prioritise getting someone out quickly — get in touch by phone or WhatsApp and we'll assess urgency straight away.

Can you fix low water pressure in an older property?

Often yes — low pressure is usually down to old narrow-bore pipework or a failing component rather than something unfixable. We diagnose the actual cause before recommending a fix.

Do you replace old lead pipes?

Yes — lead supply pipes are still found in some older North London properties and we can assess and replace them as needed, usually alongside wider plumbing or renovation work.
