Our Story

We’ve Offered Siding Service in Island Lake Since 2004

Gen-Ex was established as a fully licensed and insured business in 2004 by Paul Antonou and David Johnson. Paul and David have been long time friends both with over fifteen years of experience in the trade. combined they have worked on countless roofs as laborers and shinglers gaining the experience needed to gain their contractors license and start building their own business.

Together they have built this company from the ground up establishing strict guidelines to stay up to date on safety and industry standards. Safety precautions we follow include and are not limited to:

  1. Keeping the job site clean at all times.
  2. Protecting your landscaping assets by building tables and tarping off any areas over your plant life.
  3. Taking pictures of your property in its entirety before and after the job to ensure that any damage that preexisted is documented, protecting homeowner and Gen-Ex alike.
  4. Creating and following an extensive check list custom to every job, and double checking every item on that list to get the job done right the first time. Also after completion, a Gen-Ex supervisor will walk through the job with the customer discussing all steps and answering any additional questions the homeowner might have.
  5. We follow all appointed legislated safety guidelines and employees all wear compliant safety gear and harnessing on jobs with harness needs.
