Mortise Lock Installation & Repair in Cupertino, CA.

Mortise Lock Installation & Repair in Cupertino: here is what the job involves and how to book it.

A mortise lock is a complete lock case that sits in a pocket cut into the door edge, with latch, deadbolt, cylinder and trim all working through one body. They are the standard on heavy-traffic commercial doors, schools, hotels and older buildings because the case absorbs abuse that a cylindrical lock cannot. We install new mortise locks in prepped and unprepped doors, rebuild worn bodies, change functions and trim, and keep original hardware in historic buildings working where the parts allow.

The technician comes to your address in Cupertino, in Silicon Valley. The dispatch line at (888) 492-0666 is answered around the clock, and the dispatcher confirms the details and an ETA before anyone is sent.

• Survey of door thickness, existing mortise pocket, backset, handing and the function the room needs
• Grade 1 mortise lock bodies installed in prepped hollow metal or wood doors, or a fresh mortise pocket cut where the door allows it
• Rebuild of worn or failed bodies: broken springs, stripped hubs, bent latch bolts and jammed deadbolts replaced inside the case
• Function changes (office, classroom, storeroom, entry, privacy) by swapping the case or the internal parts where the manufacturer supports it
• Cylinder and trim work: mortise cylinders pinned to your master system, lever or knob trim, roses and escutcheons, ADA-compliant lever trim
• Strike, latch and deadbolt alignment so the door closes and locks without slamming or lifting the handle
• Service on early-20th-century mortise locks, including sourcing compatible parts or fitting a modern body behind the original trim

• Authorization from the business owner, facilities manager or property manager; historic buildings may also need sign-off from whoever oversees preservation requirements
• Photos of the door-edge faceplate (which usually carries the brand and model), the trim on both sides, and the strike
• Door thickness and material if you know it (1-3/4 inch is standard; thicker doors need longer spindles and cylinders)
• The function you want: always locked from outside, lockable from inside with a button or thumbturn, or free during business hours
• Your existing key or master system records if the new cylinder must join a keying system

Typically 45-90 minutes to replace a mortise lock body and trim in a door that already has the matching pocket and face prep. Cutting a new mortise pocket in a solid wood or hollow metal door, converting a door from cylindrical to mortise, rebuilding an antique case, or matching obsolete trim extends that, often to a half-day for the harder cases.

• Mortise bodies are not universal. Case size, backset, cylinder thread and trim spindle vary by manufacturer and era, so a replacement must match the pocket or the door needs rework. We confirm the model from the faceplate first
• Fire-rated doors: a mortise body on a rated door must be listed for it, must latch automatically, and cannot be field modified beyond what the door's listing allows. Cutting a new mortise pocket into a rated door is generally not permitted
• Doors on a required exit path must open from inside with a single motion. Functions where the deadbolt must be retracted separately are not allowed there, and we select functions that comply
• Some antique lock parts are no longer made. We can often repair springs and fit replacement cylinders, but a fully worn case may need a modern body behind the original trim
• Lever trim on accessible routes follows accessibility rules for operation and mounting height. We install to them, but the building inspector makes the final call on the building
• Cylinders joining a restricted keyway require the registered authorizer on file before keys are cut

Lock body grade and function, new installation versus repair, whether the door needs a fresh pocket or face prep, trim style and finish, cylinder keying (standard, master or restricted), and the number of doors set the price. Rebuilds of historic locks are quoted after we open the case and see what is salvageable.
