On-Site Building Services
When you purchase through a local authorized Heritage Steel dealer, your greenhouse isn’t just dropped off — it’s professionally installed right in your backyard by experts who know exactly what they’re doing. We offer full on-site building services to ensure everything is assembled correctly, securely, and ready for use.
What to Know Before Delivery
Building Permits
The customer is fully responsible for checking local building requirements to see if any permits are required to construct the greenhouse.
Site Preparation
Prior to the delivery of your greenhouse, it is crucial to ensure your site is level. We recommend the ground be level within 4" front to back and side to side. Improperly prepared sites may delay the setup or construction of your structure and result in additional fees.
Unsuccessful Delivery
If our driver is unable to deliver your greenhouse due to limited access to the site or because the site has not been properly prepared, a 10% fee will be charged. This fee must be paid to the driver at the time of attempted delivery; a new delivery date will not be scheduled until the fee has been paid.
