Frequently Asked Questions

Do I need a professional assembler for my Janssens’ Royal Victorian glass greenhouse? If so, how do I find one?

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!

What if I need assembly help?

We are also able to video calls via Facetime or Google Meet as needed. We want to help you to get through any assembly questions so you can get to the fun part – enjoying your new greenhouse!

Can someone help me decide which greenhouse is best for me?

Over the years we have personally supported many customers choose their greenhouse and options – and that expericence goes a long way. You can also find additional resources and inspiration on our blog too.

Do I need a permit?

You might need a permit. Not everyone does and even sometimes those who do need a permit do not apply for one. Each municipality sets their guidelines for what types/size of buildings need a permit in their area – sometimes this is based on square footage or whether they consider it a “permanant structure” – but this is all decided by your local permit office. If you are applying for a permit, you should always go through this process BEFORE you order your greenhouse – depending on local wind/snow load requirements you may need additional reinforcements or supports to reach your local requirements. You may also find other restrictions for placement that may mean you have to limit the size or location. If you are going to get a permit, it is always best to know the restrictions ahead of time.

Do you provide structural certifications for the Janssens greenhouses?

We have general structural certifications for most of our regularly stocked models to give you a realistic idea of the loads of each greenhouse. However, if you are applying for a permit you may need a letter stamped by an engineer certified by your state, or you may need a site specific certification. We do not provide these state or site specific documents, but they are avaialble for a fee. Conversely, we may be able to point you toward an engineer that can assist you with the documentation you need. Keep in mind, each location/state has different load requirements. If you are in a location that has higher load regulations, you may need to purchase additional reinforcements.
