🧱 How to Choose the Right Construction Company in 2025
🏗️ Introduction
Building a house or renovating a property is a major investment—both financially and emotionally. That’s why selecting the right construction company is a crucial step for the success of your project. But how can you navigate the dozens of players on the market? Here are the essential criteria to consider in 2025.
1. 🏢 Verify Legal Existence and Registration
First and foremost, make sure the company is legally registered in France:
💡 A serious company should be able to prove its legal status and stable existence.
- Active SIRET number (can be checked on societe.com)
- Registration with the Répertoire des Métiers (for craftsmen) or the Trade and Companies Register
- A clear, non-fictitious physical address
💡 A serious company should be able to prove its legal status and stable existence.
2. 🛡️ Demand Mandatory Guarantees
Every construction company must provide the following legal guarantees:
📎 Always ask for a valid copy of the insurance certificate.
- Ten-year guarantee (garantie décennale): covers major structural defects for 10 years
- Professional liability insurance
- One-year completion guarantee (garantie de parfait achèvement)
- Two-year equipment guarantee (garantie de bon fonctionnement)
📎 Always ask for a valid copy of the insurance certificate.
3. 📁 Check References and Past Projects
- Ask to see completed or ongoing projects
- Visit projects similar to yours if possible
- Check before/after photos and the materials used
💬 Customer reviews (Google, Houzz, forums) are also very helpful to identify the strengths and weaknesses of a contractor.
4. 📄 Compare Estimates Carefully
Get at least 2 or 3 detailed quotes and compare:
🛑 Be cautious of quotes that seem too low—they often hide incomplete services or inferior materials.
5. 🧑🔧 Prioritize a Local and Responsive Company
Companies located near your construction site are often:
🏡 If you're building on the Côte d’Azur, choose a company familiar with local PLU regulations, protected zones, etc.
- More available for on-site visits
- Better informed about local constraints (urban planning, soil, climate)
- Easier to verify through word-of-mouth

6. 🧾 Clear and Well-Framed Contract
Before signing, demand a detailed written contract that includes:
📑 For private works, this is usually called a "contract for hire of work" (contrat de louage d’ouvrage). For individual homes, the CCMI (Contrat de Construction de Maison Individuelle) is highly recommended.
- The total price including VAT and terms for price adjustments
- Execution time frame and penalties for delays
- Plans, measurements, types of materials
- Terms and conditions for termination

7. 🧰 Certifications and Quality Labels
Not essential, but a valuable plus:
🏅 A quality label is not mandatory, but often a sign of reliability and technical expertise.
- RGE (Recognized Environmental Guarantor): mandatory to access certain state aids (e.g. MaPrimeRénov’)
- Qualibat, Qualifelec, Certibat: signs of professionalism in their fields
- NF Habitat, Passive House, BBC Effinergie: for environmentally high-quality construction

A good professional will:
🧑💻 Some even offer a client portal to track project progress online.
- Provide a clear project timeline
- Ensure smooth communication (regular calls, progress updates)
- Agree to hold on-site meetings
