The state of New Jersey does not offer a contractor license designation. State law does require contractors to register annually with the New Jersey Division of Consumer Affairs. This registration must be prominently displayed on all of the contractors commercial vehicles, places of business, and business related documents, contracts, and correspondence. The registration number must begin with the letters HIC reg.#

William Mc Mahon currently holds license 19HC00321100, 21AI01242900 (Hvacr Contractor, Registered Architect), which was Active when we last checked.

New Jersey state law requires all contractors to maintain an active general liability policy. It is always a good idea to hire contractors with both general liability and workers' compensation insurance policies. Request copies of both insurance certificates before any work begins.

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.
