Questions about Commercial Lock Repair, Replacement & Installation

Can a commercial mortise lock be repaired?

Sometimes. We check the lock body, cylinder, lever, latch, strike and door alignment before confirming repair or replacement.

Can you replace a commercial lockset or cylinder?

Yes, when the existing preparation and compatible replacement hardware are identified.

Do you install new commercial locks?

Yes. We can install a compatible mortise lockset, cylinder, lever or related locking hardware after the door preparation and use requirements are confirmed.

What if the door still will not latch after lock work?

The door, frame, hinges or strike alignment may be the cause. We inspect the complete opening and correct the fit before recommending more lock work.

I hired DoorWin services to replace two cracked glass windows for a unit at my triplex. An exterior porch window and interior stairwell window I just needed the panes of glass replaced and not the entire frame . DoorWin was happy to do the job. Unlike some other companies who wanted to replace the entire frame at a higher cost. They were very quick with a quote and were able to perform the job on an extremely tight timeline that I had to unexpectedly move up. Very professional. Friendly. Dependable. Competitive prices. Took away all materials and left a clean worksite. Would highly recommend and will work with them again if I need another window repair.
