How to Fit a Gate Spring

A gate spring is a simple yet effective piece of hardware that automatically closes a gate after it has been opened. It is often used on garden gates, side entrances and small driveway gates where homeowners want to keep the entrance secure without needing to remember to close it each time. Fitting a gate spring can seem daunting at first, but with a little preparation and a clear method it is a straightforward job that can be completed with basic tools.

What is a Gate Spring and Why Use One

A gate spring is a metal spring with a tension mechanism that attaches between the gate and the supporting post. When the gate is pushed open, the spring stretches or winds, creating tension. As soon as the gate is released, the stored energy pulls the gate back to the closed position. This makes them especially useful in households with pets or young children, where gates need to be kept shut for safety. They are also handy for side or back gates that are often forgotten, offering a level of security and convenience without relying on human memory.

Preparing the Gate and Post

Before fitting the spring, it is important to check that the gate is already hanging correctly. If the hinges are loose or the gate is sagging, a spring will not solve the problem and could make it worse. The gate should open and close smoothly without sticking against the post or dragging on the ground. If adjustments are needed, deal with those first by tightening or realigning the hinges. The supporting post should also be firm and set in the ground securely. If the post moves when pressure is applied, it will need resetting before adding any new hardware.

Positioning the Gate Spring

Most gate springs are designed to be fitted on the side of the gate where the hinges are located. The spring runs vertically, with one end attached to the gate itself and the other fixed to the post. The correct position depends on the size and weight of the gate, but as a general rule it should be mounted roughly halfway up the gate. This provides the best balance of strength and leverage. If the gate is particularly tall or heavy, a second spring may be required for even closing. Mark the fixing points with a pencil before drilling, making sure the spring will be able to extend freely when the gate is opened.

Fitting the Spring in Place

Once you have marked the fixing points, drill pilot holes for the screws that will secure the spring brackets. Fit the bracket on the post first, tightening the screws firmly into place. Then attach the other bracket to the gate, again ensuring that it is straight and level. Many gate springs come with adjustable slots or holes so that the tension can be set to the right level later on. Once the spring is fixed, gently open and close the gate to check that it operates smoothly without catching or twisting.

Adjusting the Tension

The key to a properly working gate spring is the correct tension. If it is too loose, the gate may not close fully. If it is too tight, the gate will slam shut too forcefully, which can cause damage over time. Most modern gate springs have an adjustment mechanism, such as a winding bar or tension pin. By turning or repositioning the adjustment, you can increase or decrease the strength of the spring. It is best to make small adjustments and test the gate after each change until the desired closing speed is achieved. A correctly set spring should close the gate firmly but not with enough force to cause a loud bang.

Maintenance and Longevity

A well fitted gate spring should provide years of reliable service, but like all hardware it will need occasional maintenance. Over time, dirt, rust and weather exposure can affect the performance of the spring. Applying a light coat of lubricant such as a silicone spray or a dab of general purpose oil will keep the mechanism moving freely. Check the fixing screws every few months, as movement of the gate can cause them to loosen. If the spring begins to lose its strength or fails to close the gate consistently, it may be time to replace it with a new one.

Cost of a Gate Spring

Gate springs are relatively inexpensive compared to other forms of gate hardware. A basic spring can cost as little as £8 to £15 from DIY suppliers, while heavier duty versions for larger gates may cost £20 to £30. Professional installation, if required, would typically add £40 to £70 in labour costs depending on location and gate type. For most homeowners, fitting a spring themselves is a simple way to save money while still improving the security and convenience of their property.

When a Gate Spring is Not Suitable

Although very useful, gate springs are not suitable for every type of gate. Heavy driveway gates made from solid wood or metal may be too large for a standard spring, requiring more robust closing systems such as hydraulic gate closers. Gates that open outwards onto a public path may also not be ideal, as the sudden automatic closing could create a hazard. In these cases, it is worth considering whether a self closing hinge or a more advanced system would be more appropriate.

Conclusion

Fitting a gate spring is a straightforward home improvement project that can greatly improve both security and convenience. By ensuring the gate and posts are in good condition, positioning the spring correctly, and carefully adjusting the tension, homeowners can enjoy a gate that closes itself every time. Regular checks and light maintenance will keep the spring working well, making it a cost effective solution that requires little effort once installed. For most gardens and side entrances, a gate spring is a small investment that makes a big difference.
