These add visual weight and charm without sacrificing convenience. - Historic properties near Mystic or Noank may call for more customized solutions. wood doors or composite wood-look doors that echo the architectural period of the home.

The Installation Process: What Actually Happens

2. Door delivery and old door removal On installation day, the crew removes your existing door and hardware. Most pros can pull out an old door and hang a standard replacement in half a day. Custom sizes or structural complications can extend the job to a full day.
3. Track and hardware installation New tracks, springs, cables, rollers, and hinges are installed. The door panels are assembled in the opening and connected to the track system.
4. Opener connection and testing The opener is connected, safety sensors are set and tested, and the door balance is checked. A properly balanced door should hold itself open at the halfway point without the opener's help.
