Why It Matters
The wrong contractor can turn a dream renovation into a nightmare ā cost overruns, delays, poor workmanship, and legal disputes. Taking time to properly vet contractors saves money and stress.
What to Look For
Credentials & Qualifications
- Business registration: Verify they're a legitimate registered business
- Trade licenses: Required for electrical, plumbing, HVAC, and structural work
- Insurance (liability + workers' compensation): Ask for certificates, not just claims
- Bonding: Protects you if contractor abandons the job
Red Flags to Avoid
- No written contract or vague terms
- Demands large deposit upfront (over 30%)
- Quote much lower than others (often means cutting corners or change orders later)
- No physical office or just a mobile number
- Pressure to start immediately
- Won't provide references or past work examples
- Wants to skip permits
Questions to Ask Before Hiring
| Question | Why It Matters | Good Answer |
|---|---|---|
| How long have you been in business? | Stability and experience | 5+ years with consistent work history |
| Are you licensed and insured? | Legal protection | Yes, with documents to verify |
| Who will supervise daily work? | Accountability | Named supervisor who's on site regularly |
| What's your payment schedule? | Cash flow protection | Tied to milestones, not dates |
| How do you handle changes? | Avoiding surprise costs | Written change orders with pricing before work |
