Periodic Maintenance

Midland Glass Company recommends periodic services to ensure your doors are running at peak performance, even years after your warranty has expired.

We offer annual and biannual maintenance contracts as well as seasonal contracts. We can also create customized periodic maintenance contracts for property managers, servicing building inventory on a rotating basis, depending on doors’ usage and environment.

During a Periodic Maintenance visit, our service technician will inspect and adjust your doors for:

  • Proper alignment
  • Proper closing speed and back check
  • Sufficient weather stripping
  • Lubricated pivots and hinges
  • Tightness of handles
  • Overall performance
  • Inspect for leaking closers

At the time of the visit, our service technician will repair any problems with the door(s) providing that custom hardware is not needed.

Customers with periodic maintenance plans receive preferred rates in Emergency Calls as well as Friends and Family discounts on any door replacements covered in the Service Contract.

Call Midland Glass Company at (301) 846-4188 about setting up your periodic maintenance plan.
