Webb vs Mountfield Outdoor Storage Box

Webb vs Mountfield: Which Outdoor Storage Box Should You Choose?

Outdoor storage boxes protect garden tools, cushions, and equipment from the elements. Webb and Mountfield are both established UK garden brands, but they take different approaches. Webb focuses on modern resin boxes that are lightweight and maintenance-free. Mountfield offers traditional wooden boxes that blend into natural settings but demand regular upkeep. This comparison examines their construction, security, ease of assembly, and real-world durability to help you decide.

Material and Build Quality

The core difference between these brands is material. Webb uses UV-stabilised polypropylene resin. This material resists fading, cracking, and rotting. Owner reviews on retailer sites like B&Q and Amazon consistently praise Webb boxes for not warping or discolouring after two to three years of UK weather. The resin is lightweight, making the box easy to move around the garden, but it can feel less rigid than wood when fully loaded.

Mountfield boxes are made from FSC-certified timber, usually pressure-treated softwood. This gives them a solid, traditional appearance. The wood is heavier and provides a stiffer structure. However, multiple owner reviews note that the wood can split around screw holes during assembly if over-tightened. Mountfield recommends annual treatment with a wood preservative or stain to prevent grey discolouration and rot. Without this care, the wood's lifespan drops significantly.

Capacity and Practicality

Both brands offer a range of sizes. Webb's most popular models hold 150 to 300 litres, suitable for a few cushions and small tools. The resin construction means the box has a lower weight capacity (around 50-80 kg) compared to wood. The lightweight design also means the box can slide on grass or patio slabs when empty, which some owners find annoying.

Mountfield boxes typically offer 180 to 400 litres. The heavier timber construction supports more weight (up to 100-120 kg). Owners report that the box stays put even in strong winds. The deeper wooden boxes can store larger items like lawn aerators or bags of compost. The trade-off is that the wooden box is much harder to move once assembled.

Assembly and Installation

Webb storage boxes use a clip-together panel system. Most owners report assembly takes 15 to 30 minutes with no tools required. The panels click into place with a satisfying snap. Some reviews mention that the lid hinges can feel flimsy, but they hold up well under normal use. The lightweight panels are easy to manoeuvre alone.

Mountfield boxes require more effort. The pre-drilled panels need to be screwed together. Assembly time ranges from 45 to 90 minutes depending on the model. A cordless screwdriver is recommended. Owners report that aligning the panels can be fiddly, and the screw holes sometimes don't line up perfectly. The finished box is solid, but the assembly process is more demanding.

Security and Weather Resistance

Both brands offer basic security features. Webb boxes have an integrated padlock eye that accepts standard padlocks. The resin lid is lightweight, so a determined thief could potentially break it. Owner reviews suggest using a heavy-duty padlock as a visual deterrent. The box is waterproof, with a raised base to keep contents off the ground. The UV-stabilised material prevents fading, but dark colours can still absorb heat in summer.

Mountfield boxes use metal hasps for padlocks. The wooden lid is more robust than resin, offering better physical security. The pressure-treated timber resists water ingress, but the box is not fully waterproof. Owners report that water can seep through the lid gaps during heavy rain. Annual treatment with a waterproof sealant is essential to maintain weather resistance. Without it, the wood can absorb moisture and swell.

What to Check Before Buying

Before purchasing, measure the space where the box will sit. Ensure there is enough clearance to open the lid fully. Consider the weight of the items you will store. Resin boxes are fine for cushions and light tools, but wood is better for heavy equipment. Check the warranty length and what it covers. Both brands offer one-year limited warranties, but some retailers offer extended cover. Finally, think about maintenance. If you want zero maintenance, choose resin. If you prefer a natural look and are willing to treat the wood annually, choose timber.

Mistakes to Avoid

A common mistake is underestimating the weight of a wooden box. Once assembled, moving a Mountfield box is difficult. Place it in its final position before filling it. Another mistake is not treating the wood immediately. Mountfield boxes arrive with a basic pressure treatment, but applying a wood stain or oil before assembly extends the life significantly. For resin boxes, avoid placing them on uneven ground. The lightweight design can cause the box to wobble or tip if the base is not level. Finally, never overload a resin box beyond its stated capacity. The panels can bow or crack under excessive weight.
