Guarantees and protections: what to check before signing with a painter

Choosing a painter to freshen up your apartment in Paris or renovate a house in Brittany is not just about comparing prices. Understanding the guarantees and knowing what to check before signing a contract protects you against disputes and ensures a result that meets your expectations. Here are the practical points that really matter.

Professional status: verify SIRET and registration

Before accepting a quote or contract, make sure the painter you contact is properly registered. The SIRET is the legal identifier for any French professional1, and its presence on the quote confirms that you are dealing with someone operating within the legal framework.

To verify this 14-digit number, you can consult the free official business directory (annuaire-entreprises.data.gouv.fr) or services like societe.com. These platforms tell you whether the company is active, whether it is in liquidation or financial difficulty. On our platform, this verification is done for you: we ensure that each painter is properly registered, whether self-employed or a formal company, before presenting them as an option.

If a professional does not mention any SIRET on their quote, ask for it in writing. Without a valid SIRET, you have no legal recourse in case of dispute, poor workmanship, or the tradesperson disappearing.

Decennial and biennial guarantees: when do they apply to painting work?

The question of decennial guarantee often comes up, and it is important to understand the scope of its application to painters. In principle, painters are not required to take out decennial insurance to cover their work, but there are certain specific cases where painting work falls under decennial liability2.

In practice, the decennial guarantee covers damage that compromises the building's structural integrity or renders it unfit for use. For a painter, this mainly concerns external facade work or waterproofing, such as facade painting that serves an impermeabilization function. If faulty paint allows water to penetrate walls and creates significant infiltrations, the decennial guarantee can be invoked.

Conversely, simple aesthetic defects (fading color, brush marks, uneven finish) are not covered by the decennial guarantee: they are covered by the warranty of proper completion, valid for one year after work acceptance. The biennial guarantee covers detachable equipment elements for two years, such as certain suspended ceilings or partitions, but rarely concerns the paint itself.

If your work includes facade renovation or waterproofing services, verify that the painter has valid decennial insurance coverage. You can ask to see this document and, if necessary, contact the insurer to confirm it covers the planned work.

The quote and contract: what must be included to avoid surprises

A good quote protects you as much as the professional. It must specify the surfaces to be painted (in m²), the type of paint used (brand and finish if possible), the number of coats, surface preparation (filling, sanding, primer), and execution timelines. It must also mention the applicable VAT rate and payment terms.

When work is quoted on a per-m² basis, remember that such pricing always remains indicative. Two surfaces of the same size can be in very different conditions (cracks, moisture, damaged plaster). The final price can only be confirmed after assessing the actual condition of the walls. This assessment can be done via detailed photos and videos, or during an on-site visit: both work the same way and allow the painter to understand precisely what needs to be treated. On our platform, we systematically request photos and videos before finalizing a quote, precisely to avoid mid-project adjustments.

On our platform, all job details, once agreed, are accessible online for you, for the painter, and for us. This prevents misunderstandings: the agreement is in writing, visible to all three parties, and everyone knows exactly what is planned.

Payment terms: how to protect yourself

Payment arrangements deserve particular attention. On our platform, payment is split in two stages: 50% at the start to reserve the date and buy materials, and 50% at the end, after you have verified the work. This system protects you: you only pay the balance if the result matches what was agreed.

Beware of requests for full payment in advance, especially in cash. A serious professional will never ask you to pay everything before starting, and certainly not without issuing an invoice.

What you can verify yourself: reviews, past work, and responsiveness

Beyond guarantees and legal status, take time to check recent reviews of the professional (ideally feedback from the past two years). Ask to see photos of projects similar to yours: a painter who regularly works in Haussmann apartments in Paris or in houses in Brittany will know local specifics (humidity, old surfaces, moldings).

Also observe the painter's responsiveness during initial exchanges. A professional who answers your questions clearly, explains their quote, and agrees to show you their SIRET certificate and insurance documents is generally reliable.

What to do if a problem occurs after work is completed

If you notice a defect within the year following the end of work, contact the painter in writing (email or registered mail) detailing the problem and attaching photos. The warranty of proper completion requires them to intervene to correct any defects.

If the painter does not respond or refuses to intervene, you can contact a consumer mediator or reach out to the departmental consumer protection authority (DDPP). You can also report the dispute via signal.conso.gouv.fr, which forwards your case to the DGCCRF.

What you should remember before signing

Before committing to a painter, ensure their SIRET is valid and their status is active. Ask to see their insurance certificate if work includes waterproofing or facade renovation. Verify that the quote details surfaces, preparation, products, and number of coats, and that it specifies payment terms. If the quote is based on a per-m² price, confirm that the painter has actually seen the surfaces (via photos/videos or a visit) to avoid mid-project adjustments.

A clear contract, known guarantees, and staggered payment protect you from nasty surprises. You can then follow your project's progress with peace of mind, knowing that you and the painter share the same understanding of the work to be done.
