Before you Hire

Here are some rules, regulations, and laws governing general contractors in Pennsylvania:

What else should I know before hiring Design Air Llc

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 best way to use BuildZoom is to let us recommend contractors for your remodeling projects.

Homeowners who hire through BuildZoom's free bidding system report high rates of satisfaction, and homeowners who research contractors online are twice as likely to be happy at the end of their project.

If you hire a contractor through BuildZoom, that contractor is accountable to us. We can enforce standards of behavior, mediate disputes, and guarantee satisfaction.
