Frequently Asked Questions

What does a general contractor do?▼

A general contractor oversees the entire construction project from start to finish. They hire and manage subcontractors, obtain permits, coordinate inspections, manage the budget, and ensure the project meets building codes and quality standards.

How do I verify a general contractor's license?▼

Contact your state's contractor licensing board or visit their website. Most states maintain a searchable database where you can verify active licenses, check for complaints, and confirm insurance coverage.

What should be included in a general contractor's contract?▼

A thorough contract should include the full scope of work, materials specifications, project timeline with milestones, total cost with payment schedule, change order procedures, warranty terms, permit responsibilities, and dispute resolution process.

How long does a typical home renovation take?▼

Timelines vary widely based on scope. A kitchen remodel typically takes 6 to 12 weeks. A full home renovation can take 3 to 8 months. New construction usually ranges from 6 to 14 months depending on size and complexity.

Should I get multiple bids from general contractors?▼

Yes, obtaining at least three bids is standard practice. Compare not just price but also scope detail, timeline estimates, material specifications, and warranty terms. The lowest bid is not always the best value.
