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?

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!

Where are Janssens’ greenhouse made?

Janssens has been manufacturing quality greenhouses for over 75 years in Lier, Belgium.

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

Our retailers are great resources to reach out to discuss greenhouses – and our Exaco customer service team is always ready to help your dream greenhouse come to life – we are just a call away. 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.

Testimonials

The Victorian added functional beauty to our open area protected and partially shaded by cedar trees. The size is perfect for over-wintering our tropical and succulent plants, while allowing room for container-grown vegetables. In the spring, seed starters and perennial cuttings take center stage.

- Yvonne
"Our primary goal in choosing a greenhouse was to be able to garden year-round & to have a place to relax outdoors in beautiful North Carolina. We spent alot of time reviewing various greenhouse brands and styles and finally settled on this one. It is truly fabulous to be able to enjoy the four seasons without being in the elements (rain) and having insects (mosquitos) constantly disturbing you. This greenhouse is both functional yet beautiful. It truly has met & exceeded all of our expectations."

- Diane D.
"My wife loves this greenhouse! We purchased a VI 36 Royal Victorian Greenhouse from Exaco and assembled it, adding a 30" brick retaining wall for the foundation. The results were beautiful and functional. For aesthetics and visual effects, we went with glass instead of polycarbonate. We also went with three small heaters on automatic thermostats, the main fan, and a couple of portable fans. Fantastic—I'm thrilled that we decided to buy one. We'll do this again for the next house."

- Gary G.
"One of our best investments. Victorian VI46 greenhouse has changed the way we garden and extended our season. We saved so many years plants this winter by moving into the greenhouse. Saved us thousands of dollars. Last freeze we moved plants to our flatbed trailer, covered with a tarp and had 2 plug in heaters. We lost power and we'll you can guess the rest. We have been able to cool this greenhouse down with the exhaust fan and louvered and ceiling windows. The shelving is super sturdy and I have heavy pots/plants. The structure is strong and sturdy and the French door works perfectly. The Double doors we are still tweaking but almost there. The screens for the windows fit perfect. We bought extra shelving just in case and plan to purchase the new roller shade cloth for this summer. The only regret we have is that we didn't get one sooner; I know it sounds corny but my husband and I have enjoyed it more than we ever thought. We had several dinners out there in the spring and spent hours enjoying the birds and sunsets. We can't say enough about Diana and the install team support. Overnighted any part we needed during the construction and walked us through any trouble we had no matter how minor. We installed it ourselves so we called in quite a few times. Exaco makes an excellent product and we couldn't be happier with our decision.

"So very happy with our Royal Victorian greenhouse. A great storage for all our garden tools It is also an outdoor living room. Coffee and listening to the early birds in the morning is a wonderful start to our day. It is a library for many of Patti's gardening books and is the focal point of the garden and a highlight of our many garden tours."

- Carl
"Couldn't be happier. Purchased greenhouse in 2021 and couldn't be happier. Waited 30 years to put my cacti and succulents in a greenhouse, and the Royal Victorian is a dream come true. Very happy with the quality and sturdiness of the structure. Incorporating temperature controlled louvre windows, roof vents, and exhaust fan has really helped manage temperatures in the Texas weather. The team at Exaco was fantastic to work with as we did our initial sizing and planning. The Royal Victorian helped us transform our backyard into a beautiful, peaceful space with great energy. We couldn't be happier."

- Andy
I purchased this greenhouse last year. It is solid and very attractive addition to yard. I purchased with the polycarbonate panels. These panels did not allow for the louver side window but they did give me an extra roof window. The instructions were a bit difficult to follow. Read the instructions ahead to ensure a step isn't missed.

- Walker
"I’ve been so pleased with my Royal Victorian greenhouse. I can now put big pots of agave inside for the winter, instead of buying new ones. We started seeds inside for plants that butterfly caterpillars eat, and we now get so many butterflies! It’s been a wonderful addition to our home and garden. It’s attractive to look at as well. In addition, the service from Exaco has been excellent. Whenever we needed anything, they rushed it to us right away. They’ve been both helpful and friendly. I’m very happy with my purchase!"
