When hiring a contractor, you should check their licensing and insurance, experience and expertise, reputation and references, communication skills, and ensure they provide detailed estimates and contracts.

Here's a breakdown of key things to check:

Licensing and Insurance:
Verify that the contractor is properly licensed for the type of work you need and confirm they carry adequate liability and workers' compensation insurance. Ask for proof of insurance, according to This Old House.

Experience and Expertise:
Look for a contractor with proven experience in projects similar to yours. Inquire about their specialization and ask to see a portfolio of their past work.

Reputation and References:
Check online reviews, read testimonials, and speak with past clients to get a sense of their reliability and customer satisfaction. Be wary of a "too perfect" online reputation, says Arocon Roofing and Construction.

Communication Skills:
Ensure the contractor communicates clearly and effectively throughout the process, from initial discussions to project updates and addressing concerns.

Detailed Estimates and Contracts:
Obtain a detailed written estimate breaking down costs for labor, materials, and any other fees. A comprehensive contract should outline the project scope, timeline, payment schedule, and dispute resolution clauses.
