Construction companies work on remodeling, additions, and new construction. Construction project managers and general contractors manage and coordinate the entire building process, including estimating the job, providing the materials and tools, and hiring subcontractors for the construction work.

Hiring a small or large construction company requires planning accordingly, asking questions, and learning their work process. To hire the best:

• Get at least three in-person estimates to compare.
• Ask for recommendations from family, friends, and neighbors.
• Verify their insurance, worker’s compensation, and bond guarantees.
• Read reviews and check out their previous work on HomeGuide and Google.
• Pick specialized contractors over general ones if it’s a specific project.
• Consider hiring a general contractor to manage large projects.
• Ask about their warranties and guarantees.
• Ask for a full itemized contract in writing in case of a dispute.
• Avoid making large payments upfront. Come up with a payment schedule for work completed.

The average cost to hire a construction worker is $50 to $100 per hour for a general contractor and $50 to $80 per hour for a handyman, plus materials. However, most general contractors charge 10% to 20% of the total construction cost.
