It is essential that all garden buildings are assembled on a firm, level and completely flat base. This needs to be one whole pad, we cannot build on to rows, blocks or a bare frame. Without the correct base, buildings may be very difficult to assemble and in many cases may be assembled incorrectly leading to future deterioration of the product such as doors dropping or being out of square and becoming difficult to open/close or water leakage. Assembling a garden building on an incorrect base is also likely to invalidate any guarantee that your product may carry. If the building cannot be installed on the installation day due to issues with the base, full payment is due on the day and a reinstallation fee between £400 - £600 may apply to cover the costs of a reinstall at a later date once the base has been corrected.
Please also make sure to leave enough room around your base & building to treat all panels as required after installation.
