What to Look For Before Hiring a Construction Contractor
Hiring a contractor isn’t just about comparing prices; it’s about finding the right partner for your vision. Here are the most important factors to consider:
1. Licensing & Insurance
Ensure the company holds an active CSLB license. Ask for proof of insurance and worker’s compensation coverage. This protects you from potential legal or financial issues during the project.
2. Portfolio & Past Projects
A reliable contractor proudly showcases completed projects. Review their gallery or visit sites if possible. At Conversion Building Group, for example, every project reflects craftsmanship, attention to detail, and California-compliant design standards.
3. Transparent Pricing
Avoid vague estimates. A good contractor provides a detailed quote that includes materials, labor, and timeline. Transparent pricing builds trust and prevents disputes.
4. Communication & Project Management
Effective communication ensures your expectations are met. Ask how the company handles project updates, changes, and timelines. Consistent follow-ups indicate professionalism.
5. Customer Reviews & Testimonials
Check Google, Yelp, and Houzz reviews. Look for recurring positive themes such as timeliness, honesty, and responsiveness.
6. Warranty & After-Service Support
Quality contractors stand by their work. Ask about warranties or maintenance services after project completion.
