Painting contract: what to include and how to protect

When hiring a painter, the mistake is not in failing to have a contract. It is in having a contract that says nothing, or says everything so vaguely that it protects no one when something goes wrong.

Why a written agreement makes a difference

A written agreement is not bureaucratic formality. It is the document that defines what will be done, how, when and for how much. The legal guarantee for services in Portugal is 2 years, but it only works if the scope of the work is clear from the start. When the owner and the professional sign (or accept) a detailed quote, both know what to expect. And when a problem arises, this document is the only objective reference to resolve the situation. On our platform, all work details are recorded online: the client, the professional and the platform have access to the scope agreed in writing. This prevents misunderstandings and gives security to both parties from day one.

What must be included in the contract or accepted quote

A good painting contract must identify the parties involved (client and professional), describe the work to be performed with precision (rooms, surfaces, walls and ceilings), specify the type of paint and finish chosen, indicate the number of coats included and set the execution timeline. It must also show the total agreed value, payment conditions and indicate whether the price includes materials or not. On our platform, the payment model is always 50% at the start (to reserve the date and purchase materials) and 50% at the end, after verification of the work. Additionally, the document should mention the preparation work included (sanding, primer application, repair of small cracks) and confirm that there is written guarantee about the service provided. It is important to remember that when a quote is based on square metres, that value is always indicative. Two surfaces with the same area may be in very different states, with cracks, moisture or unevenness that alter the real cost. For this reason, our platform always requests photos and videos of the surfaces before closing any quote, precisely to avoid surprises during the work.

How to confirm the professional is registered

Before accepting any proposal, it is essential to confirm that the professional or company is duly registered to operate. In Portugal, anyone working as self-employed must be registered as an independent worker (autónomo) with the Tax Authority and Social Security. Anyone working through a company must have an established business, with a valid tax identification number. This verification is not just a formality: it protects the owner in case of dispute and ensures that the professional is in regular standing with the State. Our platform performs this verification for you: before presenting any professional as an option, we always confirm that they are duly registered to carry out the activity, either as self-employed or through an established company. This saves the owner time and eliminates the risk of hiring someone operating irregularly.

Remote quote, equal guarantee

Many owners still believe that a quote is only serious if there is an on-site visit. This idea is outdated. A quote can be made from photos and videos or from an on-site visit, and both methods work the same way. What matters is that the professional has seen the space, one way or another, and that the quote reflects the real condition of the surfaces. In practice, anyone sending detailed photos and videos of walls, ceilings and areas with visible problems is giving the painter the same information they would obtain on a visit. What is important is that the professional has enough information to calculate the actual work, not just the paintable area. For this reason, never accept a quote made by phone, without any visual contact with the space. But do not insist on a visit as a prerequisite either: well-made photos and videos are as valid as an on-site visit, as long as they show the true state of the walls.

What to do when something goes wrong after the work

Even with a well-made contract and registered professional, problems may arise after work completion: paint that flakes, stains that reappear, uneven finishes. The legal guarantee for services in Portugal is 2 years. In practical terms, good painting should last 5 to 10 years on interior walls and 3 to 5 years on exterior walls, depending on exposure. When something fails before that period, the first step is to contact the professional in writing (email, message or through the platform) and describe the problem with photos. If the defect is clearly the result of poor workmanship, the professional should correct it at no additional cost. If there is disagreement about the cause (for example, moisture that appeared later), it may be necessary to obtain an independent technical assessment. On our platform, the client can always report the problem through the system, and the support team helps mediate the situation, ensuring that both parties have access to the work record and the agreed scope. This transparency facilitates resolution and protects whoever contracted in good faith.
