Gazebo Maintenance:

The Mercia Gazebo is made from pressure-treated timbers for excellent durability and longevity. These products have an anti-rot solution in the timber structure, improving rot resistance. Mercia Garden Pressure Treated products come with a 15-year Anti-Rot guarantee. The manufacturer recommends that if you want to paint your garden gazebo with a different colour, ensure the treatment you choose is recommended for pressure-treated timber.  The manufacturer requires the gazebo to be treated with waterproofing upon construction. Applying a water-repellent product to your wooden garden bar is required for even more longevity and extra protection.

Depending on the installation option for your order, you will be contacted within the delivery timescale and given a date for either delivery/assembly on the same date or a separate date for delivery and assembly.
