Wood is a natural material, growing and adapting depending on the temperature, humidity and other weather conditions especially during the first month after the assembly. It is common that you must adjust doors and windows a few times during the first month after the wooden cabin has been erected and then once or twice in a year to keep them functioning properly. Small cracks, knots and color tone differences are not errors but inherent qualities of wood. It is important to treat your garden house with wood preservative stain or other protective coatings straight after the assembly. Untreated wood becomes grayish, and can turn blue and become moldy or rot.  We recommend that you treat floor boards with a wood impregnation agent before installation, especially the bottom sides of the boards, because after the assembly you have no more access to that side. Having been properly treated, your log cabin’s lifespan has been increased significantly. It is wise to inspect your summer house once in the year and retreat accordingly to the instructions set by the wood preservative manufacturer.
