Plumbing overhaul in Portugal
A plumbing overhaul in Portugal runs from €8,000 and typically takes 3 to 6 weeks. Older buildings with galvanised or lead pipework often take longer once a contractor can see what is actually behind the walls. remodel.pt matches you with an alvará-verified contractor experienced in riser connections, and checks the itemised quote against regional project data before you see it.

What's included
Pipe replacement
Old galvanised or lead pipework replaced with current-standard piping, sized correctly for the property and fixture count.

Boiler replacement or installation, sized to the property, with hot water delivery checked across every outlet.
New bathroom plumbing
Supply and drain lines run for new or relocated bathrooms, connected to the building riser and tested before tiling begins.

What we verify
Every plumbing contractor meets the same standard
Alvará de construção, valid construction licence checked against the IMPIC registry before any contractor joins the network.
Civil liability insurance, active policy confirmed, with coverage limits noted on file.
Working English, confirmed before joining, enough to discuss scope, materials, and changes without confusion.
Riser and drain experience, prior plumbing overhaul projects checked, since connecting to the building riser correctly is where inexperienced contractors cause the most damage.
