Hiring Contractors
Finding a fair and trustworthy contractor is important to receive high-quality work and avoid scams. Here are some key tips:
- Verify Licensing and Insurance
- Ensure the contractor is licensed and insured in your state.
- Ask for their license number and verify it online if possible.
- Check Reviews and References
- Look up Google, Yelp or BBB reviews for patterns of complaints.
- Ask the contractor for references from past clients.
- Get Multiple Quotes
- Request several estimates from different contractors for comparison.
- Be cautious of very low bids— sometimes this can indicate cut corners or hidden fees.
- Avoid Large Upfront Payments
- A small deposit may be reasonable, but be cautious of contractors requiring 100% payment upfront.
- Get a Detailed Written Estimate
- The estimate should include materials, labor and total cost.
- Ask about potential extra costs before they start, and be sure any response is documented in writing.
- Beware of High-Pressure Sales Tactics
- A good contractor won’t rush you into a decision.
- If they claim you need urgent repairs without proof, get a second opinion.
- Ask About Warranties
- A reputable contractor will often offer a workmanship warranty.
- Most materials also come with a manufacturer’s warranty.
