The Alton Cedar greenhouses do have more pieces and steps to the assembly than our other greenhouses. We have found that if you are intending to have a DIY assembly, it is very helpful to have a good knowledge of working with wood and have tools on hand. Taking your time during assembly and reading through the manual ahead of time helps immensely. Many people who have purchased the Alton cedar greenhouses do end up hiring an assembler. We do maintain a referral list of independent assemblers, please give us a call or email us and let us know where you are located and your greenhouse and we put you in touch with a couple assemblers in your area. If you prefer to work with someone local -handyman businesses and landscapers are great assemblers too! Exaco does provide all US customer support and we are here to help with any assembly questions that you or your assembler may have. Just give us a call!
