Pennsylvania does not have any licensure or certification requirements for most construction contractors. However, on July 1, 2009, the Home Improvement Consumer Protection Act (Senate Bill 100) took effect. This law requires most home improvement contractors to register with the Pennsylvania Attorney General’s Office.

Contractors in Pennsylvania do not have to take an exam prior to registering as home improvement contractors.

Registered home improvement contractors in Pennsylvania must show proof of general liability insurance, workers' compensation insurance is not required. It is a good idea to only hire contractors with current general liability and workers' compensation policies. Be sure to request copies of insurance certificates for each before any work begins.

Pennsylvania has some of the lightest regulations on home improvement contractors in the US and there is no financial or criminal background check performed on contractors by the State. The Pennsylvania State Police maintain a publicly accessible database so consumers can run their own background check before making a hire if they are so inclined.

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.

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.

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