Gate repair

Repairing a gate promptly prevents further structural damage to posts and piers, which can be far more expensive to replace than the gate itself. For homeowners with automated systems, regular maintenance and professional repair are also legal requirements to ensure the safety of pedestrians and vehicles.

What Does the Work Involve?

• Initial Inspection: Assessing the gate, posts, and piers for rot, rust, or structural movement to determine if the issue is mechanical or foundational.
• Hardware Replacement: Removing worn or rusted hinges, drop bolts, and latches and replacing them with heavy-duty, weather-resistant alternatives.
• Structural Realignment: Adjusting the gate's hang to resolve dragging or sticking, often involving the reinforcement of existing posts.
• Timber & Metal Repairs: Replacing rotten wooden boards or performing minor welding on metal frames to restore integrity.
• Post Remediation: Excavating and replacing loose or rotten posts, including pouring new concrete footings (post-crete) where necessary.
• Automation Diagnostics: Checking motor performance, control boards, cabling, and safety photocells to identify electrical faults.
• Refinishing: Applying protective coatings, such as wood stain or metal-specific paint, to prevent future weather damage.

Typical Costs

Prices are influenced by the material of the gate and the complexity of the repair. Automated gate repairs are generally more expensive due to the specialist diagnostic equipment required and the cost of electronic components.

How Long Does It Take?

• Hinge or Latch Adjustment: 1–2 hours for a straightforward fix to a single gate.
• Post Replacement: 4–6 hours, though the gate may need to remain off its hinges for 24 hours while the concrete cures.
• Automation Fault Finding: 1–3 hours to identify and potentially repair wiring or sensor issues.
• Full Structural Overhaul: 1–2 days if multiple posts need replacing or significant welding is required.

DIY or Professional?

Minor repairs, such as oiling hinges or replacing a simple latch on a wooden garden gate, are well within the capabilities of a competent DIYer. However, structural issues like leaning posts or sagging heavy metal gates require professional intervention to ensure the gate is balanced and safe.

Warning: Never attempt to repair or adjust automated gate motors or control panels yourself. These systems involve high-voltage electrics and significant mechanical force; they must be serviced by a qualified professional to comply with UK safety laws.

Choosing the Right Tradesperson

• Check Specialisms: For wooden gates, a carpenter or general handyman is suitable; for automated gates, look for an Alarms & Security specialist.
• Verify Accreditations: For electric gates, ensure the pro is Gate Safe or DHF (Door & Hardware Federation) registered.
• Ask for a Quote: Always request a fixed price for the diagnostic visit and a written estimate for any follow-up parts and labour.
• Questions to ask:
  • Are you qualified to work on mains electrics (Part P)?
  • Will you provide a safety force test certificate after repairing my automated gate?
  • Do you offer a guarantee on the replacement parts?

UK Regulations

• Planning Permission: Generally, gates over 1 metre high next to a highway, or 2 metres elsewhere, may require planning permission.
• Part P Building Regulations: Any new electrical supply to an automated gate must be installed and certified by a competent person.
• The Machinery Directive: Automated gates are legally classified as "machinery." Repairs must ensure the gate meets current safety standards, including force limitations and safety sensors.

Common Problems

• Ground Heave: Frost or soil movement can shift gate posts, causing the gate to catch on the ground or fail to latch.
• Timber Rot: Water ingress at the base of posts or behind hinges can compromise the wood's integrity, leading to sudden failure.
• Inadequate Drainage: Standing water around gate footings accelerates rust in metal and rot in timber; ensure the ground is tapered away from the post.
• Safety Sensor Failure: Cobwebs, dirt, or sun glare can interfere with photocells on electric gates, preventing them from closing.

Frequently Asked Questions

Why is my wooden gate sagging?

Sagging is usually caused by either loose hinges or the gate frame "dropping" due to its own weight. This can often be fixed by adding a diagonal cross-brace or installing a "turnbuckle" tensioner to pull the gate back into a rectangular shape.

Can I turn my manual gate into an automated one?

In most cases, yes, provided the existing posts are strong enough to handle the force of the motors. A specialist will need to inspect the structural integrity before recommending a surface-mounted or underground motor kit.

How often should I service my electric gates?

Domestic automated gates should be serviced at least once a year. This includes checking the oil levels in hydraulic rams, testing safety sensors, and performing a force test to ensure the gate won't cause injury if it hits an obstruction.

Do I need a professional to replace a gate post?

It is highly recommended. Gate posts support significant weight and leverage; if they aren't set deep enough (usually at least 2 feet) or with the correct concrete mix, the gate will quickly begin to lean or fail again.

What is a 'Force Test' and do I need one?

A force test uses a specialised meter to measure how much pressure a gate exerts if it hits something. Under UK law, automated gates must not exceed specific force limits to prevent crushing injuries. You should receive a certificate for this after any major repair.
