Contractor stopped work in Portugal? What to do when your building project goes wrong

You've paid the contractor. The work isn't finished.

Stop treating this as a contractor problem

It is now a project recovery problem. Your objective isn't to prove that the contractor is terrible. It is to answer seven questions.

Until you can answer those, you don't know how serious the situation is.

Don't send any more money

If payments have moved well ahead of construction progress, the first priority is to stop that imbalance growing. A contractor may tell you:

That might even be true. But sending more money into a distressed project without understanding its financial and construction position increases your exposure.

Get an independent assessment of the project

This is probably the most important step. Bring in an independent construction professional, engineer, architect, quantity surveyor or experienced project manager who is not financially connected to the contractor. Their job is to establish the actual status of the project.

Imagine your original contract was €400,000. You've paid €360,000. The contractor says the project is almost finished. An independent assessment might find something very different.

These numbers are illustrative, but they show why the assessment matters. The important number isn't the percentage complete.

What will it cost to get from where you are today to a completed house?

That becomes the basis for every decision that follows.

Document everything

Before relationships deteriorate further, create a complete record of the project.

Then photograph the entire project, not just the obvious unfinished areas.

If a dispute develops later, evidence matters.

Check exactly who you contracted with

This sounds obvious. It often isn't. Was your contract with:

You should also check the contractor's construction credentials.

Do not assume that because somebody has been building houses for years everything is in order. Verify it.

Review the contract before terminating anything

This is where professional legal advice becomes important. Your contract may contain provisions covering:

If the contractor is in breach, there may be a formal procedure to follow before you terminate. Do not simply send a WhatsApp saying:

You may have legitimate reasons for ending the relationship, but terminating incorrectly can complicate your position. Have a Portuguese lawyer experienced in construction contracts review the agreement and advise on the next step.

Put the problem in writing

At some point, informal WhatsApp conversations need to stop.

Your letter should clearly establish the issues. For example:

The purpose isn't to write an angry letter. It is to establish a documented position.

Determine whether the contractor can actually recover the project

This is one of the hardest decisions. Not every delayed project needs a new contractor. Sometimes the builder has hit a temporary cash-flow problem, a subcontractor issue, a materials delay or another project that has disrupted scheduling.

If the contractor can still complete the project, keeping them may be faster and less expensive than replacing them. But promises aren't enough. If you agree to continue, insist on a written project recovery plan.

1. Week 1
   Roofing completedVerified before payment
2. Week 2
   Windows installedVerified before payment
3. Week 3
   First-fix electrical completedVerified before payment
4. Week 4
   Plumbing completedVerified before payment
5. Week 5
   Plastering beginsVerified before payment

Each stage needs a clearly defined deliverable. Future payments should then follow independently verified progress wherever possible.

Don't finance promises. Pay for verified progress.

If necessary, prepare to replace the contractor

Sometimes recovery isn't realistic. But bringing another contractor onto a half-completed project creates its own challenges. The new contractor needs to understand:

This is why the independent assessment comes before hiring contractor number two. Otherwise you risk replacing one uncertain situation with another.

Understand your escalation options

If negotiation fails, there are formal routes.

The right route depends on the contract, the amounts involved and the facts, so get Portuguese legal advice before deciding how to proceed.

Payment structure matters enormously

The best time to solve this problem is before construction starts. Imagine a €400,000 build. Instead of paying because the contractor asks, the contract sets clearly defined milestones.

The principle is simple: money released should broadly follow independently verifiable progress.

Protect the project, not just the price

Owners spend a lot of time comparing contractor quotations.

But choosing the right contractor is only part of managing construction risk. The structure around the contractor matters too. Before a major renovation or new build, you should know:

1. Who is managing the project?
2. Who independently verifies progress?
3. What triggers each payment?
4. What happens when deadlines are missed?
5. Who approves variations?
6. What happens if the contractor stops working?
7. What money remains unpaid at practical completion?

A good contract cannot guarantee that nothing will go wrong. A well-structured project can make the difference between a manageable construction problem and a financial disaster.
