When customers approach your business, they absorb many visual cues about your establishment. Easily noticeable is whether the glass in your storefront and door are in good repair or if the door does not work properly. Turn every potential customer into a loyal client with exceptional glass care. Glass Doctor® of Johnson City, TN experts have the experience to provide manual door closer repair and maintenance services for your commercial door needs.
How Door Closers Work
A well-functioning door closer ensures the door to your business operates properly following local building codes, fire ordinances, and ADA accessibility requirements. By storing the energy used to open the door in a torsion or compression spring, a manual door closer releases the energy to close the door. Although a properly installed door closer provides some resistance as the individual opens the door, the resistance gives way to a gliding door as it opens. When the person stops providing resistance, an internal spring forces the device's arm to close the door gently into the doorframe.
Types of Door Closer Repairs
Glass Doctor of Johnson City, TN service professionals commit to providing high-quality maintenance, repairs, and replacement services of all types of manual doors to help further enhance your businesses.
Our experienced service professionals have the skills to install and maintain a door closer and adjust the spring to prevent a variety of potential problems, including:
- Misalignments
