            Please note: Images show accessories and furnishings for display only and are not included in your purchase.

            Pergola Maintenance:

            The Mercia Pergola 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 pergola with a different colour, ensure the treatment you choose is recommended for pressure-treated timber.  The manufacturer requires the pergola 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.

            On the morning of your delivery date, you'll be sent an update by text with an estimated 2-hour delivery slot (this update can only be provided where a mobile number has been supplied on the billing address section at the time of checkout) together with a link to the manufacturer delivery portal where you'll be able to track your order.

            Please note: Mercia Metal Sheds ONLY - your order is delivered by a courier you will not be notified prior to the delivery. If you are not in on the day of the delivery you will be carded and asked to contact the courier to arrange a new mutual delivery date.

            Upon Delivery

            Your order is delivered either kerbside or driveway and will be delivered on either a 3.5T, 7.5T or 18T Lorry. Unfortunately due to health and safety and insurance liabilities the driver will not be able to take your goods around to the back of your property but may upon request place the product at the side of the house if there are no access or restriction issues. We would not risk damaging your property whilst delivering a product to an unsafe location. Unfortunately, we will not be able to go through your property.

            We would recommend against arranging for a third party to install the building before it's been delivered and checked that all parts are present, as we cannot be held liable for any third-party costs.


            Orders with Assembly 

            The lead time for our installation option is around 7 Weeks from the date of order. With the installation option, the majority of orders will have their delivery and installation on separate days; there will be a small number of orders which will have delivery and installation on the same day. You will be advised by the manufacturer's installation team which category your order falls into.

            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.
