Door Services

Our expert team will provide custom door services to fit the specialized needs of your business.  

Repair & Replacement

Door Doctors has pioneered many innovative methods to increase the longevity, security and function of the frames we install. Door Doctors certified welders are able to rework and repair existing frames and in most cases retain the existing fire rating.

Field Modifications

Door Doctors technicians can modify door height, door width and can assist in the conversion of hardware preps. This includes making a frame wider or narrower as conditions dictate. This also includes modification to out-of-level or out-of-plumb conditions.

Life Safety Compliance

The experienced door technicians assess, document and offer solutions to bring life safety openings into compliance before official inspections occur. Door Doctors will work closely with reporting agencies and can be onsite during inspection.

Electronic Access

We will nvestigate, document and supply hardware that will meet the specified requirements. Electronically activated locking systems that tie into access control systems is a specialty of Door Doctors, and our team can work with customized access systems.

About Us

Formerly Chicago Hollow Metal, Inc., The Door Doctors have been in business since 1987. Thomas Johnson formed the company after identifying a need for quality work within the door and hardware field.

The Door Doctors specialize in field modification to installed openings as well as installation and repair of commercial, industrial, institutional, and multi-unit doors, frames, and hardware.

Design, supply and implementation of the finished product is also an option with the Door Doctors complete turn key package.

Life Safety Compliance field surveys are a valuable service that has been offered to our customers since day one. These inspections are performed by field technicians and project managers that have extensive knowledge of NFPA 80 and 101 codes and requirements. Survey sheets are done on Microsoft Excel Spreadsheets to enable easy (non-propriety) access by all building managers and owners.


Please pass along a great compliment from me. The work has exceeded my expectations and if we ever need door work perform in the future we will keep your company in mind.

Every one of their employees are concerned on doing the best job possible for us. It is refreshing to see that they do not just treat us as a “job” but rather an ongoing customer.
