Do not buy a Halls Popular Greenhouse because it is rubbish!
I wish I had read the many many reviews which detail the defects.
The instructions are very bad with errors and are difficult to follow. They need to improve them, but from my experience of the company they probably won’t bother. I am good at DIY and it took me days to build it.
It leaks very badly, so badly, in fact water gets in through the base corner joints, large gaps at the joints in the gable, bolt fixing points, surplus holes in the sides etc. When I asked why there were holes at the joints in the gable, Halls said “the design has been like that for decades”. There are about 34 leaks in total. When I enquired as to the reason, I was told that it is quite common for “hobbiest entry level greenhouses” not to be waterproof. The marketing on the website does not say it is a “hobbiest entry level Greenhouse”. The website states that it is “ideal for all gardeners from novice to expert. Excellent build quality” An expert would not accept a badly leaking greenhouse let alone a novice. Furthermore, to describe it as “Excellent build quality” is a misrepresentation.
They suggested I use silicone to stop it leaking. However, the website doesn’t say anything about the need to use silicone and nor do the instructions. I spent days dismantling it and rebuilding using expensive top quality sealant to try to stop it leaking without success because it is such bad quality.
I bought it to replace a smaller Crittall greenhouse which I had for over 20 years and which they would also class as a “hobbiest entry level” type. In fact, it was remarkably similar in construction and it never leaked!
Halls do not deserve to be in business and I really wish I had never bought it.
