Most greenhouses come with a minimum 2 year warranty and some have even longer warranties as stated on the product pages. This guarantees your purchase against any manufacturing faults and, where applicable, also extends to your preferred metal base.
Exclusions to this warranty include:
Glazing damage, Moving parts (e.g. door rollers), Wind/storm damage, Accidental damage
Greenhouses are normally included under home insurance policies, but we advise
that you check with your insurers for confirmation.
