Quick Answer
Okay, so here's the quick and dirty on hiring a contractor. The whole game is about avoiding the smooth-talkers who'll take your money and leave you with a mess. You've gotta do your homework. That means you personally verify their license and insurance – don't just take their word for it. Get at least three detailed bids and if one's way cheaper, that’s a huge red flag. And for God's sake, call their references. A bad contractor will cost you double what a good one charges. This isn't where you try to save a buck.

Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Clearly define and write down your project scope, including specific materials, brands, and layouts before seeking any bids.
Step 2
Start your research by asking for local referrals, then vet those names online by checking their website, reviews, and any BBB complaints.
Step 3
Obtain the contractor’s state license number and personally verify its status and any disciplinary actions on your state's official licensing board website.
Step 4
Demand a Certificate of Insurance (COI) showing active General Liability and Workers' Compensation policies. Do not proceed without it.
Step 5
Get a minimum of three detailed, itemized bids and perform an 'apples-to-apples' comparison. Be highly suspicious of any bid that is significantly lower than the others.
Step 6
Request references from the contractor’s last three completed projects and physically call each one to ask about budget, timeline, communication, and overall satisfaction.
Step 7
Review their portfolio, looking for work that is very similar in style and scope to your project. Ask to see a current job site if possible.
Step 8
Interview them about their project management process, who your main point of contact will be, and how they handle unforeseen problems.
Step 9
Scrutinize the proposed payment schedule. Ensure it's based on completed milestones with a final payment held until after a final punch list is complete.
Step 10
Insist on a comprehensive written contract that includes all details: scope, materials, payment schedule, change order process, timeline, and warranty. Consider a legal review for large projects.

When to Call a Professional General Contractor
- You always need a professional General Contractor for new construction, large remodels, or any work involving structural changes.
- Call a GC whenever a project involves coordinating multiple trades like plumbing, electrical, HVAC, and framing.
- If the project is significant enough to require building permits and official inspections, a GC's experience is invaluable.
- When the financial investment is substantial. A GC provides a single point of responsibility and management to protect your investment.
- If you lack the extensive time, project management skills, or industry knowledge to oversee a complex job yourself.
Prevention Tips
- Always get at least three detailed, written bids to compare.
- Personally verify every contractor's license and insurance with the issuing agencies.
- Prioritize contractors who have extensive, demonstrable experience with your specific type of project.
- Call their references and ask tough questions about budget, timeliness, and communication.
- Never pay a large deposit upfront or make payments in cash. Stick to a milestone-based payment schedule.
- Insist on a detailed contract that covers the full scope of work, materials, timeline, and change order process.
- Trust your gut. If a contractor seems unprofessional, slick, or too good to be true, walk away.
- Establish clear communication protocols and expect regular updates throughout the project.
