Doors play an integral part in your day-to-day operations. A door that is not functioning as it should can negatively impact your business, be a safety hazard, or create a security issue.  If your commercial property in San Leandro has a door that is in need of repair, give Union Door a call. We know doors inside and out and will happily take on challenges other door companies won't.

To prevent problems before they occur, we encourage you to sign up for an annual inspection plan to ensure your doors are operational and in tip-top shape. We'll check the main parts to see if there are any technical issues or parts that need replacing. If we discover any potential problems during our inspection, we'll discuss our findings with you and make a plan to address them.
