How to Install Door Hardware the Right Way

Have you ever wondered how to install door hardware to comply with the New Zealand Building Code and all relevant standards? Proper door hardware installation has many benefits, including improved security, enhanced durability, and optimal functionality. Complying with building codes and safety regulations can also provide peace of mind by reducing the risk of legal issues or potential insurance complications.  

From choosing and maintaining door hardware to appointing a licensed tradesperson to complete the job, we explore the factors that will ensure your door hardware installation is done correctly. 

Before installing door hardware, it’s important to consider the types of fixtures that are available.

Front door handles, internal door handles, and door pulls are essential home fixtures. They ensure security and also set the tone for your home. Door handles or entry pulls come in many different designs and styles.

Door locks provide safety and security by restricting access and ensuring privacy by securing a door in a closed position. Inside the home, they are particularly popular for bathroom and bedroom doors and usually have a graspable lock to enable easy functionality.

Hinges are hardware components that provide a door-fitting solution. They allow a door to open and close smoothly while securely attached to the door frame and can also contribute to the visual appeal of your interior design.

Door stops are designed to minimise the impact of slamming doors in the home. They can be either wall or floor-mounted and are available in various finishes for pleasing consistency with your other door hardware fixtures.

When learning how to install door hardware, the first step is choosing the right fixtures to complete the project. Security, functionality, durability, and aesthetics are all important considerations in this selection process. 

ABI Interiors offers a wide variety of high-quality door hardware, including internal door handles, hinges, locks, and stops. We also provide equally elegant front door hardware, including beautiful front door handles, half-moon pulls, and round pulls. 

Our door hardware is constructed from highly durable 304 stainless steel. It is available in up to seven of our signature finishes to ensure colour consistency with other fixtures throughout your home.

Any how to install door hardware guide should clearly outline the essential tools and materials required to complete the project successfully. 

Measuring Tape: This is used for accurate measurements and placements.

Pencil and Ruler: This is used to mark out the placements.

Leveller: To ensure your door hardware is aligned correctly.

Screwdriver: A manual or electric screwdriver for driving screws.

Drill and Drill Bits: These are used to create pilot holes and make openings for locks.

Hole Saw or Spade Bit: Used to create circular holes for locksets.

Chisel: To recess hardware and fine-tune fits.

Hammer: This is for gently tapping hardware into place.

Rubber Mallet: To avoid damaging surfaces while adjusting parts.

Screws and Fasteners: These are usually included with your door hardware purchase. 

Hinge Template: To mark and drill hinge recesses accurately.

The following steps outline how your chosen tradie will likely carry out your door hardware installation: 
 

Step 1: Measure the Door Height

The tradesperson will begin by measuring the height of the door from the top edge to the bottom edge. This measurement is essential, as the door hardware needs to be installed at a consistent height for both functionality and uniformity.
 

Step 2: Determine the Lock Height

Next, the tradesperson will determine the lock height, which is typically set between 900mm and 1050mm from the floor in New Zealand. They'll usually mark around 1000mm on the door's edge as a standard height.
 

Step 3: Mark the Centreline

To ensure the hardware is centred, the tradesperson will find the midpoint of the door's width. They'll mark this centre point vertically at the lock height, creating a straight line that will act as a guide for installing the lock.
 

Step 4: Measure for the Bore Hole

For cylindrical locks or latch sets, the tradesperson will measure either 60mm or 70mm from the door's edge to the centre of the bore hole, which are common backset measurements in New Zealand. They'll mark this position, while also verifying the hardware specifications in case a different backset is required.
 

Step 5: Measure for the Deadbolt (if applicable)

If a deadbolt is to be installed, the tradesperson will position it roughly 150mm above the lockset. They'll mark this height on the door and repeat the centring process to ensure the deadbolt aligns with the lockset.
 

Step 6: Mark the Strike Plate on the Door Frame

The tradesperson will close the door and mark where the latch lines up with the frame to determine where the strike plate should go. They’ll then measure down approximately 25mm from the latch position to mark the centre for the strike plate hole, ensuring proper alignment.
 

Step 7: Measure for Hinge Placement

For the hinges, the tradesperson will:

• Measure 150mm down from the top of the door to mark the centre of the top hinge.
• Measure 250mm up from the bottom to mark the centre of the bottom hinge.
• If a third hinge is needed (often for heavier doors), they'll position it halfway between the top and bottom hinges.
   

Step 8: Double-Check All Measurements

Before proceeding, the tradesperson will double-check all measurements to ensure accuracy. They'll use a leveller to confirm that all markings are straight and correctly aligned, which helps prevent any installation issues.
 

Step 9: Prepare for Drilling

With everything marked, the tradesperson will get ready to drill the necessary holes for the lockset, deadbolt, and hinges. They'll select a drill bit that matches the diameter specified by the hardware manufacturer.
 

Step 10: Install the Door Hardware

Finally, the tradesperson will:

• Install the Lockset and Deadbolt: Following the manufacturer's instructions, they will insert and secure the lockset and deadbolt.
• Attach the Hinges: The hinges will be fixed to the door and frame at the marked locations. They'll make sure the door swings freely without sticking.
   

Install Additional Hardware: If there are other fittings, such as door stops or security hardware, they’ll follow the manufacturer’s guidelines to install these as well.

As mentioned, for safety and security and to comply with The New Zealand Building Code and all relevant standards, we always recommend appointing a qualified tradesperson to properly install all your fixtures, including door hardware.

All ABI Interiors hardware comes with comprehensive installation guides, which can be downloaded from the corresponding product pages — located underneath ‘Product Info’. Please ensure these guides are followed during the installation process.

Incorrectly installing door hardware can lead to a number of associated costs and safety and security concerns that don’t comply with the New Zealand Building Code and all relevant standards. To avoid these issues, we always advise appointing a qualified tradie to properly install all your fixtures, including door hardware, according to the installation guidelines. 

After your door hardware installation is completed, regular maintenance is essential to ensure your fixtures remain functional and aesthetically pleasing. 

Our recommendation is to regularly clean your door hardware with mild liquid detergent or soap and water. Please refrain from using cream cleaners or bleach when cleaning your fixtures, as these substances are abrasive and could impair the finish. Also, avoid using cleaning pads with abrasive surfaces, which could scratch the material. 

Look out for signs that your hardware may need tightening or replacing. Door hinges should be lubricated at least annually to help maintain proper engagement and smooth operation. You can easily complete these maintenance steps yourself.
