What to Do When Your Builder Walks Off Site in the Algarve

The instinct when a build stalls is to panic and hire the next available builder as fast as possible. Resist it. Before anyone new sets foot on site, you need a clear, documented picture of exactly what's been done, what hasn't, and what materials are already paid for and sitting on site. This becomes your baseline — for costing the remaining work, for protecting yourself against paying twice for the same thing, and for giving any new contractor a fair and accurate brief. If you're based outside Portugal and can't get to site easily, an independent building inspection report can establish this baseline for you. A qualified inspector attends site, documents the state of works against the agreed specification, and gives you a written assessment of what has and hasn't been completed. That document becomes your starting point for everything that follows.

Construction licences, utility contracts, and prior notifications with the local Câmara Municipal are often registered under the old contractor's name. When that contractor walks away, these don't pause. They quietly expire, get cancelled, or remain tied to a company that no longer has any involvement in your project. A construction licence that lapses mid-build has to be reapplied for. A utility contract registered to a dissolved company can delay connection by months. Get a full list of everything in place before you do anything else: the alvará de construção (construction licence), any prior communications or notifications submitted to the council, utility supply agreements, and any compliance certificates that have already been issued. Establish who each one is registered to and when it lapses. This is a second crisis waiting to happen if nobody attends to it — and in the chaos of a contractor abandonment in the Algarve, it almost always gets overlooked.

Picking up someone else's unfinished work is a different skill from starting fresh, and not every contractor wants the liability of inheriting it. Look for a company with a track record of completions, not just new builds, and be honest with them about the state of the site — the right contractor will want the same clarity you do. Verify their IMPIC registration before any conversation about price. Check references from previous clients, specifically asking whether they have experience completing builds started by someone else. And ask to see a finished project in person if at all possible — it tells you more than any portfolio photograph.

This is where most of the real risk sits. A good contract for this situation should cover, at minimum: payments tied to verifiable progress rather than blind trust; a sensible retention held back until the work is properly signed off; penalty terms if the finish date slips for reasons within the contractor's control; a clear warranty period; and a termination clause that spells out what happens if things go wrong again. Get a lawyer to look it over, but keep the negotiation focused — chase the two or three points that genuinely matter to you, rather than letting the contract talks themselves become the next stalled project.

Handing the keys to a new contractor and stepping back is how projects end up back at square one. Active oversight — checking invoices against actual progress, staying on top of subcontractors, keeping the admin (utility accounts, licences, inspections) current — is what actually keeps a build moving. For international buyers who can't be in the Algarve regularly, this is the hardest part. But it's also the most important.
