Door Realignment /
Resizing

Doors that stick, sag, or don't latch properly often need realignment or trimming. We adjust hinges, resize doors, and fine-tune the fit for smooth, secure operation.

Worn-out Hydraulic Closers

If your door slams or won’t close properly, it may be due to a faulty closer. We service and replace worn hydraulic door closers to ensure safe and controlled closing, especially on commercial or fire-rated doors.
