Our Process

At Jack Finn, building contractors, we consistently exceed customer expectations by providing superior service and quality craftsmanship.  When working with us, you will be teamed up with an experienced Construction Project Manager, who will work closely with you to meet your needs and to keep you abreast of all project progress.


We are registered with the state of NJ Division of Consumer Affairs as a licensed general contractor.  All of our Project Managers are certified in the new EPA guidelines for lead safety practices: Lead-Based Paint Renovation, Repair and Painting Program (RRP).  We are fully insured as are our subcontractors.

Our Project Manager coordinates every phase of the project by scheduling the subcontractors on-site, placing material orders and inspecting material deliveries and ensuring your project stays within budget.  Our Project Managers oversee the project from beginning to end. They are always available to you throughout the work day to answer any questions you may have about your project.  They are accessible via cell phone and email throughout the work day.

We maintain a database of professionals to help our clients with the many decisions that need to be made during the building process, which includes:

  • architects,
  • designers,
  • custom cabinet makers,
  • specialists in flooring and faux finishing,
  • technical and electronic systems experts for entertainment or security systems
  • material suppliers for tile,
  • kitchen appliances,
  • bath
  • electrical fixtures.
