Sheds' Maintenance Guide

Anya, Petrus, Ariane, Talia… We have designed different types of sheds to cover the lack of storage space in the garden. The smaller models can be used to cover the bike or protect the garden features when they are not in use, while the biggest design can be turned into work space where to keep the tools all year-round.


These structures are made of Slow Grown Spruce Timber and due to the nature of the material, it is more sensible to weather changes. We must give them some care from time to time to ensure they have a long live span. With a minimal maintenance, sheds will be kept in good condition for the years to come. These structures come with High Quality features as Secure Hinges, Hasp, and Pressure Treated Floor Bearers, so they are protected against rot and insect infestation. 




Base inspection: The first thing to do is checking if the base, where the product will be installed, is in good condition. It is necessary a flat, levelled and squared base, and the ground has to be appropriate to take the weight of the shed. Bear in mind that an un-levelled base will cause problems and the structure will not be safe.


Treat the timber: Some of our shed have pressure treated walls, so there is no need to worry about them. For the sheds that come untreated, we recommend to apply a treatment and continue to treat them periodically with a solvent based treatment that contains both, a water repellent and fungicide.


Mould: The mould is common in products that are made only of natural timber, without composites. If mould appears on the timber, there is no nothing to be concerned about, it is easy to address with a mould cleaner, which kill the spores. A different option is to use mild detergent and warm water.

Water ingress: Bear in mind that the shed is entirely made of natural material, so it is possible that the timber expands and contracts after extreme weather as heavy rains or burning sun, and this can lead to leak inside the building. This is no common but it can happen. We recommend to treat completely the exterior of the cabin using a suitable timber treatment. It can also be sorted by applying a thin bead of silicone down of the external corners of the cabin, after the walls have been treated.



Door adjustments: The door need to be checked from time to time and to be adjusted to keep them in good working order. If hinges become stiff, it should be greased.


Knots in the timber: Knots are a natural timber feature and are part of the beauty of this material. In order to avoid the resinous knots, it is possible to treat them using a knotting solution prior applying other treatment specifically designed for the walls.
