A commercial property in Nepean called us about a rear steel entry door that was catching on the frame every time staff used it. The door was hung on three standard butt hinges, and after years of heavy daily traffic the hinges had loosened enough that the door was sagging on the latch side. We replaced them with a full-length aluminum continuous hinge so the door closes flush and square again. Here is the full before-and-after story.
A commercial property in Nepean called us about a rear steel entry door that was catching on the frame every time staff used it. The door was hung on three standard butt hinges, and after years of heavy daily traffic, the hinges had loosened enough that the door was sagging on the latch side. That sag was wearing down the strike plate faster than normal and leaving a visible gap along the hinge side that a pry bar could exploit.
Butt hinges concentrate the full weight of a steel door onto three small points along the frame. On a residential door that is rarely a problem, but on a commercial door that gets opened dozens of times a day, those three points loosen unevenly over time. Once one hinge starts to give, the door twists slightly in the frame, and the problem gets worse every month it is left alone.
We recommended a continuous hinge, sometimes called a piano hinge or geared hinge, instead of replacing the existing butt hinges one for one. A continuous hinge runs the full height of the door and fastens into the frame with dozens of screws instead of six or nine. That spreads the door’s weight evenly along the whole opening rather than at three isolated points, which is why these are standard on most new commercial steel doors we install across Ottawa and the surrounding area.
For this door specifically, the continuous hinge also closed the gap that had opened up between the door and frame on the hinge side. That gap is a common weak point on commercial doors, and it is one of the first things we check on any commercial door repair call in Nepean, since it affects both how the door closes and how secure it is.
The photos show the process. In the first image, the original door has been removed from the frame and is resting against the opening while we prepare the jamb. The aluminum continuous hinge track sits on the ground beside our tool bag, cut to the exact height of the door before installation. Removing the door completely, rather than working around the existing hinges, let us confirm the frame itself was square and free of the kind of hidden warping that sometimes hides behind old hardware.
Once the frame was confirmed sound, we mounted the continuous hinge along the full length of the door and rehung it. In the second photo, the finished door is back in place with a new keyed deadbolt and the existing access control reader on the wall beside it still wired and functional. We were careful not to disturb the keypad or its conduit run during the hinge work, since re-terminating an access control system is outside the scope of a hinge job and is not something we touch without the property’s security contractor present.
The finished door closes flush and square, with no visible gap along the hinge side and no drag on the latch. The weatherstripping and door sweep were also inspected and left in good working order, which matters for a door this size heading into an Ottawa winter.
Nepean has a large stock of commercial and multi-unit buildings built through the 1980s and 1990s, many of which still have their original hinge hardware on back and side entrances. Those doors see far more daily traffic than a typical front entrance, and butt hinges on a heavy steel door were never really built for that kind of use. We see the same wear pattern on properties near Merivale Road and in the Bells Corners industrial area: a door that used to close cleanly starts catching, and by the time someone calls, the frame has usually shifted enough that a simple hinge swap will not fix it. Catching it earlier, like this Nepean job, means a straightforward continuous hinge replacement rather than a full frame repair.
If a commercial or exterior door is starting to sag, catch on the frame, or show a gap along the hinge side, it is worth having it looked at before the frame itself takes damage. Call (613) 265-3667 or email fixmydoornowottawa@gmail.com to book an assessment.
