"I purchased a full balcony set of glass and stainless steel fittings from Dio-Met almost 14 years ago and got a right first-time delivery which we fitted ourselves. [...] Thanks Rob for helping out in what was a relatively small order but important for us as a family. - Steven"

Hi Adam,

I still need to grout around the frame / tiles.  Once this is done I will send you some photos.  We’re really pleased with it.

Hi Steve and Lee

First may I thank you most sincerely for your excellent service and expertise. To say we are pleased with the staircase is an understatement. Your planning and manufacturing were most appreciated and you were the best of all the suppliers who supplied our extensive building project. Thank You. I will send some pics as soon as we have decorated behind it. Probably a few weeks and I will have a go at leaving reviews.

Hi Adam and Rob, just to let you know that the build of the balcony went very smoothly, it took me and a friend 2.5 days to complete (excluding foundations). Everything worked perfectly……see attached photo.  

We are very pleased with the balcony which is engineered to an excellent standard and looks great. Many thanks for all your assistance.

Fantastic company. The quality of their work is top notch and their customer service is extremely helpful and responsive. I bought both my floating stairs from them as well as a large circular cellar hatch, both turned out amazing!

Excellent product and excellent service, we shall certainly recommend you if opportunities arise.

Kind regards 





     Just a quick note to let you know how absolutely thrilled we are with the walkout balcony your company has provided. Your customer service really has been second-to-none (and extremely rare in what has been a nightmare of a project with many other contractors!)  with speed and professionalism of all corresondence. We pass on our thanks to the fitters too and will provide some great photos once the paving is finished. 

Take Care.




Adam: here are pictures of our hatch connecting the kitchen with the downstairs space. The build out downstairs is finished now. Everyone loves the hatch, and it gets a lot of attention. Thanks so much for all your help and everyone else at Dio-Met. Best, Chip

Hi Sarah, Our washing line post is up and we are very happy with it. It is sturdy and well made and the instructions for using it are clear.  There was a mix up with the courier, but sarah  took responsibility for tracking the order down and staying with it until it arrived. As it was it arrived well within the lead time quoted when ordered. We are very happy and would use this company again’

Thanks for your help



Hello Diomet

I’ve attached some photos of our balcony fabricated by Diomet and installed by our local joiner.

We’re so pleased with the balcony and we think it looks as though it’s been there forever! Thank you for our balcony and for giving us the opportunity to enjoy the view from the first floor.

Many thanks

Hi Adam, hi Sarah,

We put the stairs up today and they look excellent, we’re very pleased with the result. 

We laid a concrete slab for the posts last weekend and a steel erector put them up today.

I’ve attached some pictures, feel free to use them on your website.

You recently did a hand rail and railings in black powder coat for a property on the Isle of Skye, for a ramp up to a door. That was for my in-laws, we’ve seen pictures of the finished result as they put that up last week. So we’ve spread the word!

Kind regards,

Thanks for arranging this. It was great to get the pergola complete, ready for paving stage.

I thought you might be interested in a couple of pics of the final result. It looks great (though it will soon be covered in leaf) and should last longer than me!

Its been a pleasure working with you guys.

Hi Adam,

My Wife and I are very happy with the handrails, just what we wanted.

The handrails are not only functional but are also a piece of sculpture which enhances the appearance

We have already had compliments regarding the workmanship and design.

All the Best for the New Year to You and your Men for an Excellent Job.

The two fellas have just finished installing my pergola. I am over the moon with it. It has exceeded my expectations, and they were high. My thanks to you and all in the company who have been involved. 

When I get all the climbers planted and my patio furniture back on the patio I’ll send a photo. Then you can use it on the website if you wish.

Thanks again. Gill


We removed a staircase leading down into a small basement and fitted the walk-on-glass hatch into the floor which was an aesthetic and practical solution. The hydraulic mechanism works really well and we’re thrilled with the result. The whole process was very easy and I wouldn’t hesitate in giving this company the very highest recommendation. 


F. Boyd



Fantastic Adam, thanks. 

I’ve put pictures on Facebook and mentioned you guys. There was a lot of good feedback & We’ve recommended dio-met to several other people also. 

Once the last bit of furniture arrives, I’ll email some photos over of the completed project for your website should you want to use them.


Kind regards

Hi Steve.

Just thought i drop you a couple of pics.   We're very pleased with the product quality and the service your team provided.   My client  (my Mum in this case!) is also very pleased with the result.

Please also feel free to use any of the text above as a reference/review.

Hi Sarah,

Could you pass this on to Rob Diovisalvi please, thanks.

I've just received the glass well cover (order 8497) and would like to express my appreciation of the outstanding service I've received.

The communications have been excellent - telephone calls immediately answered and emails responded to by return. Plus the progress tracking on your web site and pallet delivery tracking and the delivery date quoted at the time of order has been maintained.

Your staff are obviously a credit to your organisation.

Thanks, regards

Clive W


Just a quick e-mail to say thank you for the work done at my Mum’s house this morning.

The rail is of a really high quality and it helps so much when the person fitting it is so pleasant and personably.

I would have no problems recommending Dio-Met to anyone and I am sure you will have at least one more order from that row of houses if not more.

Best Regards

Steve B...


Hi Adam , hope you are well. Just wanted to send you some pictures of our most recent project using Dio-met . Again we are very pleased with your service & the product. 

Many Thanks for all your help.

I have just completed my staircase project involving the replacement of wooden spindles with glass panels. Just wanted to thank you not only for the quality of your products, but also for the excellence of your service and advice making the job so simple for a basic diyer such as me

Hi Adam

Just to let you know having received the Balustrade last Friday I have now fitted it to the deck.

It was total DIY having never done anything like this before and it all fitted perfectly along with the helpful generic instructions.

The end result is a deck that has been enhanced by your very good quality product.

Thank you Dio-Met and I will certainly recommend your product to many of my friends.

Kind regards



Hi Sarah we received the glass but we haven’t checked it yet due to a number of reasons. 

Many thanks for all your help, you have been amazing and I hope your boss knows that. We would definitely use your company again.

Best wishes

Heather S…


Hi Adam,  We deceided not to put it on the decking after all because of the weight.  Sent you some photo’s if you want to add them to your portfolio.  Just delete if not needed.  Really glad we purchased these from you.  Many thanks



Good morning Sarah,  

The balustrade I collected last week is now fitted and I am very impressed with it, especially the workmanship on the handrails.

 Kind regards, 

John R...


Hi Adam,

I have installed the handrails you supplied and thought you may like to see a picture of the result.  My wife can now walk unaided to the car and she is very happy!

I may follow up with another order for the rear of our property in due course.

Kind regards,

Tony O… 


I bought a balustrade for a raised patio from Diomet and I'm very pleased with both the product and the service I received. The drawings were produced quickly and efficiently and the balustrade was delivered as soon as lockdown restrictions were lifted.
We had a minor problem with the handrails, but Diomet sorted it out promptly. It is a high quality product and we're very pleased with it. I have no hesitation in recommending Diomet.
Thank you Adam and Rob.

What a great team of people to work with. I first contacted them over a year ago to enquire about a walk out balcony / Deck with some very very basic photos from google earth. They were so helpful. My dreams came true when the council passed planning permission. Steve came over to my house drew up the plans and structure. We agreed on the work to start in March just as covid lockdown started so had to wait a little longer. It was so worth the wait the team came to site and were so professional. No shouting around the site, cracked on with the work from early morning until around 6pm every day through rain or shine.
I’m blowed away with how good my deck/ balcony looks. We live in a second floor flat ( We own the whole building in-laws live on the ground floor) so having a deck we can walk straight out onto gives us a whole new relaxing option.
I would recommend these guys in a heart beat. Absolutely fantastic.

We used Diomet to make a trap door for us to make a wine cellar in our new kitchen diner. This was made to measure and they took great care to make sure the design was spot on before proceeding. The trap door was made in roughly 3-4 weeks, shorter that we were expecting. Upon arrival, all we can say is that we were over the moon. This item was a pure indulgence for us, and all I can say is it didn't disappoint. The build quality and attention to detail is fantastic, I literally couldn't fault it. It came very well painted and packaged really well to protect it in transit. It was very easy to fit, and very easy to use.

We also felt very positive about supporting a local company in Sheffield, and by writing this review I hope to inspire others to use Diomet too. We will certainly use the company again if we ever need a trap door/gate/fence/handrail. Thanks again for a brilliant product!

Thanks again and hope to use Diomet again in the future!



Hello Rob

I just wanted to email and say how pleased I am with our glass ballustrade and how impressed I was with the two lads who carried out the install yesterday and today. My wife and I were both really impressed with how meticulous they were to make sure the job was just right, whilst also having the time to answer any questions I had.  They were polite and once finished, they left the patio spotless.

Please pass on my gratitude to them both, and all to Diomet who were involved in this project.


Ben & Sarah V...


Hi Sarah/Adam,

Thank you very much for our glass and your brilliant service. We will definitely use you again if needed and will recommend you to all that we can. 

Take care 

Kind Regards. 

Chris D...


Hi Adam, just a quick thank you for sending the additional grub screws so promptly.

I have to say, I am both enormously impressed with both your company and the product. I had no idea that the fencing would be such a robust product and my brother and I, without any real building experience, were able to put it up very quickly once we got the hang of it. It was certainly made quite simple with the various grub fixings which enabled us to adjust perfectly as we went along. It’s perfect for our garden as it looks very impressive without being too overbearing and certainly does the job keeping our dog contained.

I’ve attached a couple of photos and you are more than welcome to use these and my comments in any testimonials.

All the best.

Robin K



Dear "to who ever I spoke to at DioMet" 

I just wanted to say 'Thank you' for my fabulous washing line posts.   

Due to a variety of circumstances I haven't had a washing line in my garden for several years so, perhaps you cannot imagine my excitement, when I finally found these beautiful, English made posts by DioMet.

As I live in a very old stone cottage in rural Somerset these posts really complement the cottage garden & are such good quality.

Despite these extraordinary times your service was exceptional - I ordered on the Monday, you delivered on the Wednesday (packaged really well to avoid any travel damage) & my dear husband put them in on the Friday.  By Saturday morning, in the beautiful weather, my washing was blowing in the breeze.


I am so pleased with them - 'Thank you' again, very much.

Stay safe & best wishes.




Following our recent order with you for a glass canopy I attach photos.

 Your service was excellent start to finish, my profession is a Buyer fir a manufacturing company and I wish all suppliers were as efficient as yourselves. 


Angela D

I just wanted to say i had my glass panels on Friday and fitted them on Saturday. They look really really good. thank you for a very simple process and excellent communication. Sorry for all the messages before delivery but just want it to get it right.
Thanks again.
Mark G



Just a quick email to say from the first point of contact to the completion of my stairs went very well and i am more delighted. The service i got from yourself and whoever else was involved in the order no matter how small was great. It was well packaged and delivered on time.  

I will certainly be recommending you to other people that might be interested in similar projects. 

Once again many thanks 

Keith S..



My builders who erected my staircase were most impressed with the staircase quality and cost and have just asked for your details. 

They occasionally have requirements for balconys etc so you might get some more work from the West Country. Regards Dudley C



Hi Ged,

             We just want to reiterate our massive thanks for all your assistance with our stair infill, it looks absolutely brilliant and exactly what we were hoping for. Your service level and product quality was exactly what we expected too after the recommendation from our friends Sue and Paul, exemplary!

Please find attached finished pictures, hope you can make use of them.

We’ll recommend you to some other friends who want something similar too!

Thanks again
