Why Does My Door Stick in Winter?
Start with where the door rubs, how it latches, and the condition of its hinges, frame, and weatherstripping.
Lock Installation & Repair
Door Lock and Latch Replacement
A worn lockset needs compatible hardware and a door that lines up with its strike. Check both before replacing the mechanism.

Starting condition
A handle may feel loose, a latch may fail to retract, or a lock may turn inconsistently. The existing door and frame are intended to remain.
The problem
A new lockset will still struggle if the latch and strike do not align. Incompatible bore spacing or door thickness can also make the chosen hardware unsuitable.
What to inspect
- Observe the fault with the door open and closed
- Identify the lock function and existing preparation
- Check door thickness, handing and hardware dimensions
- Inspect strike support and damaged fixing holes
- Check whether the door belongs to a special or rated assembly
Recommended approach
Separate a mechanism fault from a door-alignment problem. Select a compatible replacement with the required function, preserve the assembly’s requirements, and define any drilling or local support repair before installation.
Typical scope
Preparation
- Confirm hardware compatibility and the intended locking function
Removal
- Remove the old lockset and strike where replacement is agreed
Installation
- Fit the selected hardware to suitable fixing points
Adjustment
- Align the latch and strike without forcing the door
Finishing
- Repair agreed exposed fixing marks
Cleanup
- Collect old parts and check all supplied keys or controls
Exclusions
- Access-control wiring, frame reconstruction and unsupported security upgrades need separate scope
Materials
- Compatible lockset and latch
- Matching strike and specified fasteners
- Local fixing-repair materials if suitable
- Finish touch-up materials if included
Work sequence
- Test the existing mechanism and door alignment
- Confirm replacement dimensions and function
- Remove hardware and check the fixing areas
- Install and adjust the replacement
- Test operation from both sides
Possible complications
- Old preparation does not match the new hardware
- Splintered strike area cannot hold ordinary fixings
- Frame movement causes repeated latch misalignment
Quality checks
- Handle returns and latch retracts consistently
- Latch and lock engage without lifting the door
- Hardware remains secure after repeated use
- Intended access and exit functions operate correctly
Expected result
The goal is a securely fitted lockset that operates as intended on the assessed door. No burglary-resistance rating or security guarantee is implied by a hardware replacement.
What changes the scope
- Hardware type and compatibility
- Existing door preparation
- Strike and fixing-point condition
- Alignment and finish repairs
