Frequently asked questions
Q: Is it worth repairing an old shed?
A: Repairing an old shed is often worth it if the structure is still sound and the damage is limited to specific areas like the roof, boards, or windows. It can be a cost-effective alternative to full replacement and extend the life of your shed for years. Our expert gardeners can assess the condition of your shed and carry out professional repairs, from re-felting the roof to replacing damaged boards or windows - restoring both function and appearance.
Q: What is the life expectancy of a garden shed?
A: The life expectancy of a garden shed typically ranges from 10 to 25 years, depending on the quality of materials, weather exposure, and how well it’s maintained. Wooden sheds tend to last around 15–20 years with regular treatments like painting or oiling, while metal or plastic sheds can last even longer. Routine maintenance and timely repairs, like fixing roof felting or replacing damaged boards can significantly extend the lifespan. Our professional repair services in London can help keep your shed in top condition for many years.
Q: How much does it cost to repair a shed?
A: All projects differ due to many considerable factors. It depends on the damages, materials and the workload that your service involves.
Q: Can you repair a rotting shed?
A: Yes, a rotting shed can often be repaired, depending on the extent of the damage. Localised wood rot, commonly found on shed bases, walls, or roof edges can be removed and replaced with treated timber. Applying wood preservatives and ensuring proper ventilation and waterproofing can prevent future rot. Our outdoor repair professionals in London can assess the condition of your shed and recommend the best solution, whether it’s targeted board replacement or more extensive refurbishment.
Q: How do you weatherproof a garden shed and prevent it from rotting?
A: To effectively weatherproof your shed and prevent rotting, you should: seal gaps and joints with outdoor-grade caulk to block drafts and moisture; treat the wood with weather-resistant paint, oil, or stain regularly to protect against rain, UV damage, damp, and fungal decay. You should also add shed roof felt or shingles to prevent leaks and damp, install guttering to manage rainwater runoff, and raise the shed on a base or foundation to avoid ground moisture seeping in. Ensure proper ventilation to reduce internal moisture buildup, install a moisture barrier beneath the shed to avoid ground contact, and keep the roof watertight with felt or shingles, repairing any leaks promptly. Additionally, clean gutters and remove debris from around the shed base to stop water pooling. If your shed is already showing signs of decay or you want professional protection, our outdoor repair experts in London can assess, treat, and help weatherproof your shed to prolong its lifespan. Our professional shed weatherproofing service in London includes all of this - painting, felting, oiling, and sealing to ensure your shed stays protected through every season.
Q: How do I strengthen my garden shed?
A: Strengthening your garden shed involves reinforcing weak points such as the base, frame, walls, and roof. You can add extra timber supports to the frame for stability, install a solid concrete or treated timber base, use exterior-grade plywood or OSB for wall reinforcements, re-felt or re-roof to prevent water damage, and seal any gaps and apply wood preservatives to extend durability. If you’re unsure where to start, our outdoor repair experts in London can assess and reinforce your shed to make it sturdier and more weather-resistant.
Q: How to stop a shed from sinking?
A: To prevent a shed from sinking, it’s essential to ensure it has a solid, level foundation. Options include concrete slabs, paving slabs, or a timber frame base with good drainage. Avoid placing sheds directly on soil, as it can shift or become waterlogged. If your shed is already sinking, it may need to be lifted, the ground re-levelled, and a proper base installed.
Q: Is it worth replacing a shed roof?
A: Yes, replacing a shed roof is often worth it, especially if the structure is still sound. Any leakage from your roof, as well as any other types of water damages, should be repaired as soon as possible in order to prevent more serious damages to your shed. A new roof protects the contents of your shed from water damage, extends the life of the shed, and helps prevent issues like rot or mould. If your roof felt is torn, leaking, or sagging, timely replacement will prevent further deterioration. Our professional shed roof felting service in London can restore your shed’s integrity quickly and efficiently, using high-quality materials for long-lasting protection.
Q: How do you fix guttering on a shed roof?
A: To fix guttering on a shed roof, you should assess the damage (checking for cracks, clogs, or sagging sections), clean the gutter (removing debris and dirt to ensure clear water flow), secure loose brackets (tighten or replace any loose or damaged brackets holding the gutter), and seal leaks (using a waterproof gutter sealant on any small holes or joints). If parts of the gutter are cracked or broken, it’s best to replace them. Finally, ensure proper slope, as the gutter should slope slightly towards the downpipe to allow drainage. If you're unsure or the damage is significant, our local professionals in London can repair or install shed roof guttering efficiently and ensure it's ready to handle rain without leaks or overflow.
Q: I need to have some of my fence panels replaced. Can you help me with that?
Absolutely! We offer fence repair services, so feel free to book a service whenever you prefer. We also work on emergency cases, for fallen fences after extensive storms. So whether you need a fence installation or repair, we can help.
