Choosing the right contractor is the most important decision in your renovation project. A poor choice can turn a simple project into a nightmare—delays, cost overruns, defects. A good choice guarantees quality work, on time and on budget.
Why contractor selection is crucial
In Luxembourg, the construction sector is highly active. You’ll find hundreds of contractors, but not all are equal. A competent and reliable contractor will help you avoid:
- Defective work that’s expensive to repair
- Delays that disrupt your daily life
- Unexpected budget overruns
- Exhausting legal disputes
Essential criteria to verify
1. Qualifications and certifications
Before entrusting your work to a contractor, verify they have:
- Registration with the Business Register in Luxembourg
- Business authorisation issued by the Chamber of Trades
- Specific certifications depending on work type (RGE for energy, etc.)
How to verify? Ask for the registration number and check on the Chamber of Trades website.
2. Customer reviews and recommendations
Customer reviews are your best source of information. On tack.lu, each contractor has verified ratings with:
- Overall rating out of 5 stars
- Detailed comments from previous customers
- Photos of completed work
Tip: Be wary of contractors without reviews or with only perfect reviews (5/5 everywhere can be suspicious).
3. Get multiple quotes
Never settle for just one quote. Request at least 3 detailed quotes to compare:
| Element to compare | Why it matters |
|---|---|
| Total price | Identify significant differences |
| Cost breakdown | Understand what’s included |
| Timeline | Plan your project |
| Guarantees | Protect yourself after work |
Warning: The cheapest isn’t always the best. An abnormally low quote often hides problems.
4. Verify insurance
A serious contractor must have:
- Professional liability insurance (RC Pro)
- Ten-year guarantee for structural work
Request up-to-date insurance certificates before signing.
Questions to ask before signing
At the first meeting, ask these essential questions:
- How long have you been in business? (Experience)
- Do you have references from similar projects? (Portfolio)
- What’s the expected completion time? (Planning)
- What guarantees do you offer? (Protection)
- Who will be on site? (Point of contact)
- How do you handle unexpected issues? (Responsiveness)
