Installation & Base
Installation services are available via Bourne Buildings in some locations
We cannot emphasis how important it is to have a proper base for your Greenhouse to be erected upon. It is essential that the BASE IS COMPLETELY FLAT, LEVEL AND SUBSTANTIAL enough to take the weight of the greenhouse including its glass.
Give yourself enough room around your base to allow for fitting the glass and any on-going maintenance / cleaning. A slab base which is larger than the greenhouse is the ideal solution. Slabs are ideal because they allow for some drainage between them (no greenhouse is 100% waterproof) and they will also help support the lower door runner and threshold.
Clearance
We recommend at least 18” clearance all round for installation, airflow, and future maintenance.
Guarantee
Hercules Greenhouses come with a free 10 year frame guarantee, covering the frame and powder coating against faulty manufacture. Moving parts are guaranteed for 12 months – Exclusions include: glazing, wind damage, labour & accidental damage.
