Below is a brief overview of how some of the key points of this greenhouse fairs across the market.

Guarantee

On a plastic greenhouse, the guarantee that the manufacturer offers is usually a very good indicator of the quality of the building. The longer the guarantee the more the manufacturer believes in the quality of the building they have produced. Typically we see manufacturer guarantees for plastic Greenhouses ranging from zero right up to a 15 years guarantee.

This plastic greenhouse comes with a 15 years guarantee. Most plastic greenhouse come with a 5 years guarantee (52.56% of them) [2].

For this particular brand (Halls) they offer 6 [3] different types of guarantees on their plastic greenhouses, with the 15 years guarantee on this being the only they offer. The 15 years guarantee is found on 100.00% of Halls plastic greenhouses [4]. It is great that this greenhouse was given one of the highest guarantees offered by the brand, and this shows the manufacturer has a lot of faith in the overall quality of this part of their product range.

When looking at comparable 6′ x 4′ plastic greenhouses (we found 65 of them) the most popular guarantee length offered by manufacturers was 5 years [5]. 64.62% came with a missing guarantee, 12.31% came with a 5 year guarantee, 7.69% came with a 10 year guarantee, 7.69% came with a 12 year guarantee, 6.15% came with a 15 year guarantee and 1.54% came with a 1 year guarantee.

Public-Facing – Extra security measures might be more of a concern if you’re placing your building in an area that is more public-facing than a garden. Features such as security windows or even having no windows at all, and the ability to lock all opening doors are usually much more important when you have something that is more public-facing. We found at least 3 greenhouses that have options that you might find a better fit if this is a concern you have.
