Frequently Asked Questions

How do cedar greenhouses compare to other materials?

Cedar is a premium greenhouse frame material because it is naturally resistant to rot, decay, and insects. It is structurally strong and stable, yet lighter than many hardwoods. Unlike aluminum, cedar does not conduct heat or cold as quickly, which can slightly reduce temperature transfer through the frame. Over time, it weathers gracefully and maintains its structural integrity for decades when properly maintained. For buyers who want a durable, natural, and architecturally warm frame material, cedar is a premium choice.

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

The Alton Cedar greenhouses do have more pieces and steps to the assembly than our other greenhouses. We have found that if you are intending to have a DIY assembly, it is very helpful to have a good knowledge of working with wood and have tools on hand. Taking your time during assembly and reading through the manual ahead of time helps immensely. Many people who have purchased the Alton cedar greenhouses do end up hiring an assembler. We do maintain 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 put you in touch with a couple assemblers in your area. If you prefer to work with someone local -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!

Where are Alton Cedar greenhouses made?

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.
