How important is contractor licensing in Cook County?

Although Illinois does not require contractors to be licensed, check local regulations as certain jurisdictions may require licensing on a local level.

Your liability risk when hiring Advanced Air Services, Inc

General Contractors in Illinois are not required to carry general liability insurance. It is always a good practice to only hire contractors with active liability and workers' compensation insurance policies. Request a copy of each certificate for your records before the project starts.

Financial recourse when hiring Advanced Air Services, Inc

What else should I know before hiring Advanced Air Services, Inc

Illinois on the state level, has minimal regulations governing contractor licensing, in turn, consumers should be vigilant when hiring contractors, check on BuildZoom for customer reviews, and permit history as indicators of quality businesses. Check with local licensing authorities as some jurisdictions will require contractors to be licensed.

How is the BuildZoom score calculated?

The BuildZoom score is based on a number of factors including the contractor's license status, insurance status, verified work history, standing with local consumer interest groups, verified reviews from other BuildZoom users and self-reported feedback from the contractor.

Why you should hire through BuildZoom

When it comes to major construction work or even minor alterations to your home, hiring the wrong contractor could result in incomplete or defective work. You may even find yourself dealing with huge liability claims. BuildZoom does the homework for you and helps you hire the right contractor.

You should get several bids before hiring a contractor

Before hiring a contractor in Illinois, be sure to get at least 3 detailed bids.
