Janssens Helios Master Greenhouses

The Janssens Helios Master Greenhouse is a Super Strong and spacious greenhouse, perfect for busy gardeners. It’s built from high strength Box Section Aluminium to give maximum stability in very windy gardens, with the glazing sealed into the greenhouse frame with tough rubber glazing strips, stopping any movement of glass within the frame in stormy conditions.

The Helios Master comes in two versions; the Helios Master Hobby in plain silver aluminium or the Helios Master Victorian with it’s traditional roof cresting and a powder coated green or black frame finish. All Janssens Master Greenhouses feature nice high 2m high eaves, giving great head height for comfort and the ability to grow climbing plants comfortably around the greenhouse. Choose from 8ft Wide or 10ft Wide versions.

Ordered 14/1/25 - arrived 24/4/25 with 1 item missing. Quite a delay but the construction crew arrived the same evening and were efficient, polite and tidy leaving the place without any mess or rubbish. I dealt with Ian Willstead at Greenhouse stores and my thanks goes to him for his assistance. The missing piece (a shelf) didn't arrive till 19/6/25 and can be put up at a later date. My only complaint was the long delay in delivery. Ian Willstead and the construction crew were superb.

We chose to errect the greenhouse ourselves. We found the instructions easy to follow, and although some aspects were slightly fiddly, we managed to put it all together. Have been using for a month now, and so pleased. Very sturdy, spacious inside, and looks good at the end of my garden. Due to the fantastic weather we have been having using the greenhouse has been a joy to bring on seedlings and young plants. Something I have wanted for years and finally purchased, at a very reasonable price.

There was a good selection, and ordering was easy (including requesting someone to come and put it up for us). I was a bit unclear when my greenhouse was supposed to arrive, and it does take some time. But arrive it did, and a cheerful bunch of guys put it up for us. And it's a lovely greenhouse.

I purchased a Vitavia 6x10 (check the small print it is bigger than that!) I also purchased glazing bar capping and a number of other add ons. However the other add ons don't work terribly well when using the capping so a number of mods required. I would recommen checking although I suspect no-one has thought it through! After widening my base, doing a few adaptions now a loveley Greenhouse! Also the delivery driver (solo) was unwell and only just capable off moving the kit a small distance, I had just had Covid and was suffering after effects - right team!

I have had such a positive experience dealing with Ian of Greenhouse Stores. I was not quite the customer from hell, but I seemed to be continuously asking Ian for advice, changing my mind, doub;e-checking on things. Ian was always a great communicator and helped in so many ways. He liaised with the manufacturer on my behalf (Elite Greenhouses of Bolton) and organised assemblers. I recommend Greenhouse Stores to anyone who admires my new Elite Titan!
