The 7 Questions That Expose a Bad Builder

In short — To expose a risky builder, ask seven questions:

1. is your RBQ licence valid? 2) is the factory certified (CSA A277)? 3) what warranties, from whom, and for how long? 4) what is included (and excluded) in the contract? 5) can I see delivered projects and references? 6) what is the contractual schedule? 7) how do the progress payments work? A good builder answers each one clearly; hesitations are red flags.

Choosing a builder means entrusting the biggest expense of your life to a company. You do not need to be an expert to gauge how serious they are: seven simple questions are enough to tell the difference.

The 7 questions (and the answer that reassures)

1. The RBQ licence

Non-negotiable. Any company performing construction work in Quebec must hold a valid RBQ licence. Ask for the number and verify it in the public register. No licence in good standing, no conversation.

2. Factory certification (CSA A277)

For modular production, CSA A277 certification attests to documented quality control in the factory. It is the industrial equivalent of a site inspection. See certifications, associations, and funding.

3. The warranties

Who guarantees what, and for how long? Distinguish the factory's warranty from the one covering on-site work, and check whether a new-home warranty plan applies to your case.

4. The contract's scope

This is the number-one source of nasty surprises: who handles the foundation, the transport, the hookups? A good builder spells it out in black and white. It is also the subject of the clauses to watch before signing.

5. The references

A serious builder shows delivered projects and gives references in your region. A vague refusal is a signal.

6. The schedule

Demand a written, step-by-step timeline — not a verbal average. Actual lead times depend on the project, but the commitment must be contractual.

7. The progress payments

Part of the price is paid to the factory before installation. A good builder explains the payment plan clearly and aligns it with progress. Coordinate it with your financing.

The red flags

• No verifiable RBQ licence, or reluctance to provide it.
• Vague warranties, "we'll work it out."
• A contract that is fuzzy about what is included.
• No references or projects to show.
• Pressure to sign fast, a large deposit with no schedule.
