The glass Victorian greenhouses are designed for DIY assembly by handy homeowners – although, of course, not everyone has this desire. There are also a few upgrades available that do add to the skill level required such as a hinged door, building on a knee wall or building a T shaped model – but many people do and our customer service is here to help. Exaco does have 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 can give you some assemblers in your area. Also, if you want to locate someone locally, 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!
