Outstanding Product

Review of Slimline Glazing & Aluminium Systems
Helen M (Herts)
5 out of 5

Our sliding doors (S20) are simply outstanding. Everything, from the lock mechanism to the sliders (that "glide") and the anthracite finish is outstanding. We had a couple of issues delaying installation - but Joana in the office made sure the job was completed the very next day. HIGHLY recommended

The Sliding Doors and Glass Walls Are Perfect

Review of Slimline Glazing & Aluminium Systems
Christine, Cornwall
5 out of 5

Fantastic Slimline Doors. When the plans were drawn up for the ultra contempory glass extensions to our 200 year old stone house I had a vision of how it would look and I am not disappointed. The SL18 doors and glass walls are perfect, as was dealing with the company and the team who successfully fitted the glazing on some of the coldest days of the year.

We had 12mts of SL20 Otimma sliding doors installed and they look stunning! Best system on the market. We are equally impressed with the aftersales support as when one of the doors needed adjusting due to small movement of the new house they came within a day. Special thanks to Tony and Bob.

Undergoing a full reconstruction and extension of our flat has been quite an undertaking and Tony Hall has taken what could easily be another headache and made it as fluid as I could imagine. Always contactable, it's like having your own project manager! Highly recommended.

Just a short note, to say Thank you very much for consideration and efforts on past week. You really pushed the boat out on our meeting in the factory on Saturday, to touch and compare the doors. It’s had the desired affect and we shall move on now with Slimline Aluminium throughout. Again, thank you for your excellent customer service.

We had a side extension built by Slimline glazing. Dan, the builder, was great and the work force very professional. I have to say the doors made the finishing touches - they are great. Great job all round.

I had some walk on glass fitted yesterday, which covered a big area. Slimline fitted all the steel work for installation prior to the glass. The finishing was great and they matched the mastic to the patio slab so it all blends in and looks great. We're really pleased.

We had 2 sets of the slim sliding patio doors and some walk on glass fitted just before Christmas. It was touch and go if it was going to be done before the festive season, but slimline glazing did really well and got our build water tight in time. We're really happy with the product and service. Well done to all.

We're really pleased

Last Weeks Glass Installation

Review of Slimline Glazing & Aluminium Systems
Neil Marks
5 out of 5

I just want to say how pleased we are last Thursday the final piece to our puzzle was installed we have a property in West London and we were having a big glass roof fitted we had no access through the house so each piece of glass had to be craned over the house it looks fantastic!!

So pleased with the results

Review of Slimline Glazing & Aluminium Systems
Steve & Jane Wilmslow
5 out of 5

We were recommended by a friend at work to get a quotation for the glazing as we were having a fairly large extension and the back of our house re-built and modernised. Everything was going great until our builder went bust and left us in a dilemma. Tony at the Slimline office helped us obtain a new builder and Slimline then took over the remainder of the construction works - installing their doors and windows. It took a little longer due to the hiccups we had but we are so pleased and grateful for the results.

Walk on Glass project

Review of Slimline Glazing & Aluminium Systems
Robin Walker. SW1
5 out of 5

I used Slimline for a Walk on Glass project in central London. The quality of the works is second to none and I was informed all the way through the project. I was very happy and so was my customer. I’ve since used slimline glazing on a project that involved a very complex structural glass extension. They provided all the right help from the glass and structural engineers and all drawings were designed correctly - which made the installation process a lot easier, really happy!!

3 panel sliding doors

Review of Slimline Glazing & Aluminium Systems
Mr Mikal - Ealing
4.5 out of 5

We had a 3 door set of Slimline's sliding doors installed at our property in Ealing 2 months ago. They are so easy to slide and the middle sections are so narrow. it’s great when the doors are shut as there are no thick frames that obstruct the view. We have recommended at least 3 people so far. I must say, our friends do not stop commenting on them.

Roof lanterns

Slimline Glazing installed a Slimline roof lantern for us at our restaurant when we had the refurb done, everyone one who walks in asks us were we got it from it really sets off the area were we had the work done it lets in so much light they weren’t the cheapest but the quality was second to none but everyone was so polite from start to finish and met all our requirements.

I've just had a new set of SL17 sliding doors installed by Tony and his team. What a great job. The doors have transformed my old gloomy kitchen into a bright space that's enjoyable to use again.

sl600 aluminium door

Review of Slimline Glazing & Aluminium Systems
P.T Manchester
4.5 out of 5

Although we initially wanted the sl17 doors (which are amazing but a little out of our price bracket), we opted for the sl600 in the end - which were still expensive but did fit in to our budget. We are so please with them. They're great modern door and really don't feel like a compromise. we would (and have) recommend Slimline and their doors to anyone.
