Our Story

Offering Siding Services in Spring Grove Since 2004

In 2004, Gen-Ex was established as a fully licensed and insured business by Paul Antonou and David Johnson. Paul and David have been lifelong friends and both have over fifteen years of experience in the industry. Combined they have worked on countless roofs as laborers and shinglers gaining the experience needed to obtain their contractors license and start establishing their own business.

Together this duo built the company from the ground up establishing strict guidelines to stay current on safety and industry standards. The safety precautions we follow include and are not limited to are the following:

  1. Keeping the job site tidy at all times.
  2. Use building tables and tarp off any areas over your plant life to protect your landscaping assets.
  3. Photograph the whole property before and after the job to make sure that any damage that preexisted is documented, protecting homeowner and Gen-Ex alike.
  4. Creating and adhering to an extensive check list that’s customized for 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 client to discuss all steps and answer any additional questions the customer might have.
  5. We  adhere to all appointed legislated safety guidelines and employees all wear compliant safety gear and harnessing on jobs that require harness needs.
