Many of the Janssens’ greenhouses are designed to be a DIY assembly by handy homeowners, however, this model may have some challenging sections that it may be better to have a professional assembler do. Hinged doors, knee walls, cupolas, heavy framing, T-shaped models and larger sizes are all things that can add to to level of assembly – depending on the model and options you choose. 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!
