What should you ask general contractors and builders?

Ask for the license number, insurance certificates and a written contract, then ask who runs the job, who pulls permits and what the warranty covers. For this trade, also ask: How do you handle change orders, and what markup applies? Typical lead time is often several weeks to a few months out for larger jobs.

9 Questions to Ask General Contractors Before Hiring

The Questions

What is your license number, and which state or city issued it?
Can you send a current certificate of liability insurance and proof of workers’ compensation?
Will the contract list the scope, materials, price, start and finish dates and payment schedule?
Who pulls the permits, and are they included in the price?
Who will run the job day to day, and will you use subcontractors?
What warranty do you give on labor, in writing?
How do you handle change orders, and what markup applies?
Will you give lien waivers from subcontractors with each payment?
Can I speak with two recent clients with similar projects?

Good to Know

A general contractor is responsible for the whole job; ask how subcontractors are chosen and paid.
Ask for lien waivers with each payment so unpaid subcontractors cannot claim against your property.
Keep a contingency for surprises, especially in older homes.

Cost and Timing

As a planning figure, expect often a fee of about 10–20% on top of labor and materials. Typical lead time is often several weeks to a few months out for larger jobs. These are our own assumptions, so compare written bids.
