The Nelke, Riga and Riga XL series greenhouses are designed to be assembled by handy homeowners – although of course not everyone has the inclination or time to assemble their greenhouse. Greenhouses built on knee walls can be more challenging as well as the larger Riga XL greenhouses, although we’ve had many homeowners do it. 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 the greenhouse you are looking at and we can give you a few names. Many of the assemblers on our list are local handyman businesses and landscapers – so these are also good local people to reach out to for assemblies. 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!
