Tips for Hiring a General Contractor 

Here are some important things to keep in mind when choosing which general contractor to hire.

1. Research and read recommendations. Check out the best contractors in your area on Best of the Web and take the time to read the reviews and recommendations that people left.
2. Speak with several general contractors and take careful notes during your conversations. Ask them about their experience, their estimated workload at the time of your project, and their rates and payment schedules.
3. Don’t make your decision on price alone. After you interview a few contractors, be wary of the one charging the lowest rates, especially if it seems quite a bit cheaper than their competitors’. The lower the rate, the more likely that they will cut corners on your project.

FAQ

Is it worth hiring a general contractor, or should I do it myself? 

Not every project needs a general contractor. However, be careful not to get in over your head trying to save yourself a little money. This can backfire and result in you getting fined for breaking code, or overpaying for materials or services you’re not familiar with. 

If your project is going to take more than a week to complete, requires multiple tradespeople, or involves local building codes, it’s a good idea to hire a professional.

What should you look for in a general contractor? 

Make sure that your general contractor is licensed and insured, and don’t just take their word for it. Double check with your state’s licensing authority to make sure that everything is valid. 

How much should I pay a contractor upfront? 

Every general contractor works on their own payment schedule, so your upfront fees will vary. Some states place a limit on how much you can pay in advance, so research and learn the laws in your state. As a general rule, you can expect to pay between 10-25% of the total project cost upfront, although this may vary.
