Frequently Asked Questions

What makes the Exaco Janssens Junior Victorian greenhouse a superior choice for gardeners and outdoor living spaces?

The Exaco Janssens Junior Victorian greenhouse blends classic Victorian architecture with high-performance greenhouse engineering, making it an exceptional choice for gardeners who want both beauty and functionality in their outdoor space. Designed and manufactured in Belgium by Janssens — a company known for premium glass greenhouses — the Junior Victorian delivers timeless style in a compact footprint that suits smaller gardens and yards.

This greenhouse is built with 4 mm tempered safety glass and a thick aluminum frame that ensures strength, weather resistance, and crystal-clear light transmission — ideal for healthy plant growth. The 38° roof pitch helps snow shed naturally and the full-height glass sidewalls maximize headroom and usable space inside.

Ventilation and climate control are thoughtfully integrated with automatic roof vents and adjustable windows, which help regulate temperature and airflow throughout the day. Slide-opening doors provide easy access, and heavy-duty seals around the glass improve insulation compared to many competitors.

The Junior Victorian also comes standard with gutters and downspouts for rainwater management, which you can use for irrigation or sustainable water-use practices. Its elegant finish and classic Victorian silhouette enhance any landscape — making it not just a greenhouse, but a beautiful and functional garden retreat.

Do I need a professional assembler for my Junior Victorian greenhouse? If so, how do I find one?

The glass Junior Victorian greenhouses are designed to be assembled by handy homeowners – although, of course, not everyone wants to. There are also a few things 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 we have still had handy folks build these themselves. 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 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!

What if I need assembly help?

Exaco is here to help! Our friendly customer support staff is REAL PEOPLE who have assembled these greenhouses and are very familiar with the parts and pieces. Please give us a call or email us. 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.
