Vertical blind repair

Repairing your vertical blinds is often a fraction of the cost of a full replacement. Whether it is a snapped carrier, a tangled cord, or sun-damaged slats, a professional repair can restore functionality and aesthetics while reducing household waste.

What Does the Work Involve?

• Initial Inspection: Assessing the headrail, internal carriers, and the cord or wand mechanism to identify the point of failure.
• Component Replacement: Removing broken "trucks" or carriers and installing new ones to ensure smooth slat rotation.
• Vane Maintenance: Replacing individual damaged slats or fabric vanes and ensuring they match the existing set in colour and length.
• Hardware Refresh: Replacing brittle bottom weights and snapped spacer chains that keep the blinds uniform.
• Mechanism Service: Cleaning and lubricating the headrail track and testing the tension of the control cords.
• Safety Compliance: Checking and installing child safety devices, such as cord cleats or P-clips, to meet current UK standards.

Typical Costs

The cost of vertical blind repair in the UK typically depends on the number of blinds being serviced and whether bespoke parts are required. Most professionals charge a minimum call-out fee that covers the first hour of labour.

Pricing is influenced by the height of the windows. If a specialist requires high-access equipment or scaffolding for a conservatory roof or double-height landing, expect to pay an additional £100–£250 for equipment hire and safety measures.

How Long Does It Take?

• Minor repairs (chains/weights): 20–40 minutes per window.
• Carrier or cord replacement: 45–90 minutes, as the headrail often needs to be dismantled.
• Full vane replacement: 30–60 minutes, including measuring and hanging.
• Multi-room service: 2–4 hours for a typical three-bedroom semi-detached home.

DIY or Professional?

Replacing bottom weights or clipping on a new spacer chain is a simple DIY task that most homeowners can manage. However, internal headrail repairs—such as replacing the tilt rod or re-stringing the cord—are notoriously fiddly and require specific tools.

Professional repairers ensure that your blinds comply with BS EN 13120 child safety regulations, which is a legal requirement for all professional installations in the UK.

If your blinds are old and the plastic components have become brittle due to UV exposure, a professional can advise whether a repair is a viable long-term solution or if the plastic will simply break again in a different spot.

Choosing the Right Tradesperson

• Look for members of the British Blind and Shutter Association (BBSA) for guaranteed standards.
• Ensure they carry common spare parts (carriers, hangers, and chains) on their van to avoid multiple call-out fees.
• Ask if they provide a "make it safe" service for older blinds that lack modern safety clips.

Questions to ask:

• "Do you carry stock for [Brand Name] blinds, or are the parts universal?"
• "Is the cost of replacement slats included in your quote, or is that extra?"
• "What is your minimum call-out charge if the blind is found to be unrepairable?"
• "Will you provide and fit child safety cleats as part of the service?"

UK Regulations

In the UK, internal window blinds must meet strict safety standards to prevent the risk of strangulation to young children. This is governed by BS EN 13120:2009+A1:2014.

• Cord Lengths: Cords must be kept at least 1.5 metres off the ground.
• Safety Devices: All blinds with loops must be fitted with a safety device (like a pull-away connector or a fixed cord tidy).
• Professional Liability: A professional installer or repairer is legally required to fit these devices; they cannot "opt-out" even at the homeowner's request.

Common Problems

• Snapped Carrier Lugs: The small plastic hook that holds the slat breaks off. This usually requires a new carrier "truck" to be inserted into the headrail.
• Misaligned Slats: If one slat is facing the wrong way, the internal "clutch" may be out of sync. Forcing it can snap the mechanism.
• Brittle Components: Years of sun exposure in conservatories make plastic parts turn yellow and snap at the slightest touch.
• Sticking Mechanism: Dust and grime build-up inside the headrail can cause the blinds to jerk or refuse to draw across the window.

Frequently Asked Questions

Is it cheaper to repair or replace vertical blinds?

Repairing is almost always cheaper, especially for high-quality headrails. Replacing a few broken carriers or a set of weights costs under £100, whereas a new, high-quality bespoke vertical blind can cost £200–£400 per window.

Can I replace just the fabric slats but keep the headrail?

Yes, this is a very common "refresh" service. As long as your headrail is in good working order, you can buy "replacement louvres" or slats to change the look of your room for a fraction of the cost of a full new blind.

Why won't my vertical blinds turn anymore?

This is usually caused by a snapped tilt rod or a broken gear inside the control end. A professional can usually replace the control end or the internal rod without needing to replace the entire track.

What should I do if my blind cord is too long?

For safety, you must have a cord cleat or tensioner fitted to the wall. If the cord is excessively long, a professional can shorten it and re-join it using a safety breakaway connector to comply with UK law.

Can you repair motorised vertical blinds?

Yes, but this requires a specialist who understands the specific motor brand (such as Somfy). Repairs often involve battery replacement, re-programming the limits, or replacing the motor unit itself.
