Polytunnel Levels of Repairs and Refurbishments Required

These small and large sheltered housings can often require minor and major polytunnel repairs, they are subjected to harsh UK environments and locational weather conditions throughout the year and once their cover lifespan is reached, depending on the grade quality and maintenance program. Polytunnel refurbishments or replacement coverings will be required at some point, as part of their material genetics build, and quality of materials used in the build.

They are widely used by gardening individuals, small and large-scale farming operations, community projects, allotment cultivation, and commercial growers around the UK, for their ability to create productive and controlled growing environments. Over time, however, wear and tear can take a toll on these outdoor structures, polytunnel repairs and replacements are part and parcel of their maintenance program, especially in areas prone to extreme weather conditions. The question arises whether individuals can carry out minor or major polytunnel repairs or if the case arises, that part or full polytunnel refurbishments may be the better option to ensure long-term functionality and performance integrity.

Carrying Out Polytunnel Repairs

Minor and major polytunnel repairs depend on the severity of the issue or damage and the level of expertise required to put it right. Many common repairs, such as fixing holes or tears in the covering, replacing damaged parts or tightening loose fastenings, can be done with basic tools and materials on small domestic builds. However, larger structures are more complex due to their size, height and heavier materials, repairing or replacing an entire cover or reinforcing a damaged frame, may require more equipment, different tools, and increased skill levels or assistance, especially for large polytunnel refurbishments or major repairs.

Minor polytunnel repairs are easier to administer and handle as part of routine maintenance. Small holes or tears in the covering can often be patched with repair tape or patching kits, readily available from a supplier. Individuals should regularly inspect the covering for any damage caused by wind, UV exposure, or accidental punctures. Fixing minor issues promptly can prevent larger problems from forming and help maintain the integral environment.

Over time, the tension on the cover can loosen due to wind, rain, or the material stretching. Regularly checking and tightening any loose fixings, ropes, clamps, or fastenings, that can prevent the cover from flapping in the wind, which could cause further polytunnel repairs. Keeping the polytunnel clean and free of snagging and debris is another awareness task that individuals can easily handle. Washing the cover to remove grime, dirt, algae, or mould, reduces light transmission and cover performance which affects plant growth or even re-painting it.

Major Repairs and Polytunnel Refurbishments

For environmental and operational damage, such as holes or tears in the covering or minor damage to the frame, individuals can easily carry out small polytunnel refurbishments and repairs.

If significant damage appears, such as large tears or excessive wear, the covering should be replaced. For more complex repairs, if you have the right tools and guidance or knowledge then no problem but replacing the entire cover will typically require a second person to help with fitting the new material securely over the frame and tensioning it correctly on larger frame structures.

If the frame has been damaged by strong winds or rusted over time, individuals may need to reinforce or replace sections of the frame. This can involve cutting and welding steel components, or simply bolting on new parts, depending on the nature of the damage. For large repairs, always consider seeking professional help or advice to ensure the structure remains stable and safe.

Poor ventilation adds to excess humidity, and mould or mildew, this tends to thrive inside the tunnel when conditions are favourable. Ensure ventilation and temperature systems are working and doors, vents, side flaps and doors are functioning and allowing airflow to achieve the ideal growing environment.

Full Polytunnel Refurbishments and Extension Considerations

At some point, minor polytunnel repairs can become insufficient, and part or full refurbishment is more effective. Frequently repairing small tears or fixing structural issues indicates that the materials are reaching the end of their natural lifespan and affecting performance. If the frame is damaged, bent or corroded, it could be unsafe to continue using the polytunnel without a complete overhaul. When the time comes for full polytunnel refurbishments, this can involve replacing or treating large sections of the frame or even installing a new structure if the frame is in poor condition or reached its 20-year lifespan, quality builds offer.

Robust, durable and high-grade covers can last 5 to 10 years when looked after correctly, depending on the quality of the material and the weather conditions they are exposed to. Once degraded, discoloured, or brittle, and develops frequent holes and poor functionality, it may be time to replace it entirely.

Full polytunnel refurbishments are necessary if your growing needs change, you require an extension or if you decide to grow new crops that require different environmental conditions, you might want to upgrade your polytunnel to a more insulated and robust model or one with better ventilation.

A full cover replacement may be needed every 5 to 10 years, depending on the quality and thickness, durability and grade of the covering material in place. Exposure to UV radiation and harsh weather conditions also takes its toll. Structural polytunnel refurbishments may be less frequent, but regular inspections can help you identify if larger work is necessary or if any small polytunnel repairs are needed.
