How to Maintain Your Grandfather Clock

A grandfather clock is a majestic, antique timepiece made up of complex, integrated parts. Even if it’s not in operation, the clock will need a little care and maintenance to keep it in tip-top shape. Here are some easy ways to protect and maintain the quality of your Howard Miller Grandfather clocks.

Keep It Away From Sunlight

Direct sunlight, extreme heat, and humidity can crack the case and cause the finish to fade. To keep your clock looking and working its best, store it in a cool, shady area of your home. 

Keep the Door Locked

It’s essential that the door on your Howard Miller Grandfather clock is always closed and locked. This will help prevent debris or excess dust from forming on the parts, slowing the clock down or causing damage. A locked door also prevents pets and children from coming into contact with the delicate parts.

Wind the Clock Weekly

Every seven days or so, you should wind your grandfather clock. This will help to prevent the clock from randomly stopping. Once you’re done winding it, correctly set the time by moving the minute hand. If the clock starts running too fast or slow, simply adjust the nut on the pendulum rod.

Check the Weights

The weights are what provide power to the grandfather clock. Once you’ve cleaned the hands, you should take great care to check the weights to ensure that they are still properly assembled. 

Check the Levellers

An unbalanced clock can throw the timing out of whack. From time to time, the levellers on the bottom of the clock will need to be checked. If they are unbalanced, simply adjust them until the clock sits flush with the floor.

Check the Oil

Just like a car, a grandfather clock can also seize up if the oil gets too low. You don’t have to oil the movements every time you check the clock, but you should always make sure the parts are lubricated just enough to move easily. For most models, you will only need to oil the clock movements every two years. When adding oil to the movements, remember to wear latex gloves and specialty clock oil to prevent damage to the parts during the process.

Clean the Clock Movements

Every four to five, the grandfather clock should undergo a deep cleaning of the movements. The servicing should only be done at a professional clock repair shop. DIY repairs could result in lost parts or screws or even damage to the movement, causing more harm than good.

Common Issues and Troubleshooting

Pendulum Stops Swinging

One of the most common issues with grandfather clocks is the pendulum stopping. This can often be due to several factors that can be easily checked and resolved:

1. Level the Clock: Ensure that your clock is placed on a flat, stable surface. Use a spirit level to check if the clock is perfectly vertical. If it’s not, adjust the feet of the clock until it is level.
2. Check the Pendulum: Ensure the pendulum is properly attached to the pendulum leader. A misaligned or loosely attached pendulum can cause it to stop swinging.
3. Clear Obstructions: Check that there are no objects or debris that might be interfering with the pendulum’s motion. Even a slight obstruction can halt the pendulum.
4. Wind the Clock: If the clock is not wound properly, the pendulum might not swing. Ensure the weights are in the correct position and that the clock is fully wound.
5. Adjust the Pendulum Bob: If the pendulum bob (the disk or weight at the bottom of the pendulum) is too low or too high, it can affect the swing. Adjust it slightly up or down and see if this resolves the issue.

Clock Runs Fast or Slow

If your grandfather clock is running too fast or too slow, you can adjust the speed by manipulating the pendulum nut. Here’s how:

1. Locate the Pendulum Nut: The pendulum nut is usually found at the bottom of the pendulum rod.
2. Adjust the Nut: To slow down the clock, turn the nut to the left (counterclockwise) to lower the pendulum bob. This increases the length of the pendulum, making the clock run slower. To speed up the clock, turn the nut to the right (clockwise) to raise the pendulum bob, shortening the pendulum length and making the clock run faster.
3. Make Small Adjustments: Turn the nut in small increments and check the clock’s timekeeping over a day or two before making further adjustments. This helps in achieving precise timekeeping.
4. Regular Monitoring: Regularly monitor the clock after each adjustment to ensure it’s keeping accurate time. Make further small adjustments as needed.

Chiming Issues

Chiming issues can be frustrating, but they are often fixable with a few troubleshooting steps:

1. Check the Chime Selector: Ensure the chime selector is set to the correct chime setting. Some clocks have a "silent" or "off" position that disables the chimes.
2. Wind the Clock Properly: See to it that the clock is fully wound. The chime mechanism often relies on a separate weight or spring, which needs to be wound regularly.
3. Synchronize the Chimes: If the chimes are not striking at the correct times, you may need to manually synchronize them. Move the minute hand to the 12 o’clock position and listen for the chime. If it doesn’t chime correctly, adjust the chime mechanism as per the manufacturer’s instructions.
4. Inspect the Hammers: Open the clock case and inspect the chime hammers. Ensure they are not stuck or obstructed and can move freely. Sometimes, the hammers may need slight adjustments to strike the chime rods correctly.
5. Check the Chime Rods: Examine the chime rods to see if they are damaged or bent. Each rod should be straight and unobstructed to produce the correct sound.

Seasonal Maintenance Tips

Winter Care

During winter, indoor heating can lower humidity levels, potentially affecting your grandfather clock. To maintain optimal performance, keep your clock away from direct heat sources like radiators or fireplaces. Use a humidifier to maintain stable humidity levels, ideally between 35% and 55%. Regularly check and wind your clock to ensure it runs smoothly, as cold temperatures can thicken lubricants.

Summer Care

In summer, high humidity and temperature fluctuations can impact your clock’s accuracy and condition. Place your clock in a stable, climate-controlled environment, away from direct sunlight and damp areas. Use a dehumidifier to control moisture levels, keeping humidity between 35% and 55%. Regularly dust and clean your clock, paying attention to any signs of corrosion or mold. Ensure consistent winding to maintain proper function during these warmer months.

Enhancing the Longevity of Your Grandfather Clock

Proper Handling

When moving your grandfather clock, always handle it with care to avoid damage. Remove the pendulum and weights before transport, securing them separately. Use a protective cover to prevent scratches and ensure the clock is kept upright. Enlist help to move the clock, as improper handling can misalign internal mechanisms.

Periodic Professional Servicing

Regular professional servicing is crucial for maintaining your clock’s precision and longevity. During a servicing appointment, technicians will clean, lubricate, and inspect the internal components for wear and tear. They will also ensure the clock is accurately calibrated. Professional check-ups every 3-5 years can prevent major issues and extend your clock’s lifespan.

Historical and Aesthetic Value

Grandfather clocks, also known as longcase clocks, have a rich history dating back to the late 17th century. Originating in England, these clocks evolved from simple timekeeping devices to intricate works of art. They were initially designed to improve the accuracy of timekeeping with their long pendulums, which reduced errors caused by shorter pendulums.

Design Variations

Grandfather clocks come in various styles, ranging from traditional to contemporary. Traditional designs often feature ornate woodwork and intricate carvings, reflecting the craftsmanship of the period. Modern variations incorporate sleek lines and minimalist aesthetics, blending classic functionality with contemporary design elements. Each style adds a unique touch to home decor, catering to different tastes and preferences.

Cultural Importance

In many cultures, grandfather clocks are treasured heirlooms passed down through generations. They symbolize heritage, continuity, and family history. These clocks often hold sentimental value, marking significant family events and milestones. As cultural artifacts, they represent the craftsmanship and artistic expression of their time, maintaining their relevance and appeal across generations.
