Mongolians say it will last up to 100 years. On our side, we do our very best to select quality materials for our yurts allowing them to adapt efficiently to the more humid North American climates. With a little care, the wood structure and felt insulation will last dozens of years. Should you have any trouble with the outside canvas cover after a few years, please call us as these are items we carry in stock and offer replacements at very affordable prices. Our yurts are all handmade and do not come with a warranty as such. Although we care to source the best possible quality materials for our yurts, we cannot guarantee what, how and where they will be used. However, we are always available for advice, spare parts, or questions in the event of a problem or concern. The outside canvas cover is the most likely part of the yurt to age, especially in more humid climates. We offer a 10 year “at cost” warranty on all our outside canvas covers. Even if you had to change it twice during the life of your yurt, it would still be far less expensive than any other covering on the market. Our canvas outside covers provide a healthier alternative to other fabrics like vinyl, for example!
