About our work

Project Support

Helping dreams become a reality

The demands of customers, architects and builders are simple – they want the most appropriate and best quality products, and they want them delivered quickly, and at the best price.

Amongst the many reasons we are a popular supplier and installer of aluminium window and door systems for customers, designers, builders and modern architects is the fact that we are a family run company with the founding members still involved in the day to day running of the business. That means the same shared vision of delivering ultimate and complete customer satisfaction is still upheld with each individual client.

It’s never too early to involve us in discussions about your project. The sooner we’re working with you, the better we’re able to support the project planning and ensure that architects and builders are designing in the products that will give you the end result that you’re looking for.

Details are hugely important in planning a project and our product experts are used to and skilled at liaising with your appointed architects, builders, project managers and interior designers to ensure that we’re supplying any technical advice, threshold details, and technical drawings that may be needed.

Site Survey

In the vast majority of projects we insist on carrying out a site survey. We feel that this is the best way to protect your best interests and to ensure that you get exactly what you want.

The site survey is an important stage in ensuring that the installation of your glazing goes smoothly and is co-ordinated within your overall build programme. At the site survey, one of our lead surveyors will meet with you and your builder and/or architect.

As well as taking measurements of the manufacturing sizes of each product, we will discuss important details such as the final finished floor level, the positioning of products within reveals, the cills on the windows, and the threshold you’re aiming to achieve on sliding, bi-fold and pedestrian doors.

The site survey also allows the opportunity to discussing any remaining open points and to agree any actions required in advance of the Installation.

What our customers say

We pride ourselves on approaching every project with the same excitement, energy and attention to detail that our customers have, and we aim to deliver total satisfaction every time.

Customer feedback is vitally important to our business. We welcome all feedback, as it presents a great opportunity for us to understand what is working really well, and in what areas we need to improve.

Customer referrals are a very good barometer of how we’re doing and an important source of new business. Read a selection of our customer testimonials below :

Andrew and Elizabeth Coates, Birmingham 

” it’s a magnificent working space and a huge improvement to the house and garden. I followed its progress carefully. I was impressed with the high standards of craftsmanship and finish. 

It is said that craftsmanship is dead – it was manifest in all aspects of the construction.

It was a pleasure meeting you. Your initiative deserves to succeed. It’s a fine design, after a great deal of research into similar products, we came to the conclusion that your product was the best in the field both practically and aesthetically. Both criteria are illustrated in the final product.”

Julie Holland, East Leake

‘ Many thanks for everything! We are thrilled with our new door and we have had a lot of compliments from friends, family and neighbours and even the postman!

Dave Carter, Birmingham 

‘ I’ve used Renka for two home improvement projects. They were professional and thorough in all their dealings with me. I’m really pleased with the products they’ve ‘fitted, and their fitters were excellent. I have already recommended Renka to a number for my friends’

Sara Smith, Shropshire 

‘ Great company! Can’t speak highly enough of them. I’ve just completed renovations to the back of my house. The team were helpful throughout and suggested less costly products that would be more suitable than the ones I’d initially looked at. Delighted with the results!

Lynn Smith, Worcester

‘ Great team, great products and great value for money! After a considerable amount of research and shopping around for bifolds and windows for my rear extension, I decided to work with Renka for my glazing. Their attentive and helpful responses to my questions gave me confidence that they would do a good job, and this has been carried through to the completion of my project. Give them a call!’

Sarah Collard, Cambridgeshire

‘ We used Renka for our new build. From the start, the professionalism was fabulous right through fitting and followup aftersales. 

I would very highly recommend Renka for Windows and doors. 

Very high quality and very reasonably priced!’

Sara Smith, Shropshire

‘ Great company! Can’t speak highly enough of them. I’ve just completed renovations to the back of my house. The team were helpful throughout and suggested less costly products that would be more suitable than the ones I’d initially looked at. Delighted with the results!

Kathy Davidson, Milton Keynes

‘ Renka has been excellent from start to finish! Over the past 12 months, we were planning our side and rear extension, they were helpful and informative throughout – answering all our questions and helping to flag up some issues that we should consider and plan for. We’ve now got our new doors and windows installed and are really happy with the results.’

Terry Jones, Cardiff

‘ Top notch! Renka recently installed Reynaers sliding doors and windows for me, and did a brilliant job! As a time served carpenter, I was really interested in their level of workmanship and attention to detail – neither of which I could fault. Would heartily recommend them.’

Steve Watson, Banbury

‘Really helpful team and great products. My project didn’t go at all as planned due to having to change the builder halfway through, but Renka were supportive throughout‘. Can’t speak highly enough about them.’

Linda Panford, Oxford

‘ Absolutely love the windows and doors from Renka. If we move again we will definitely come back to you

Javed Ansari, London

‘ We bought sliding aluminium doors for our loft conversion from Renka – they offered a very reasonable (comparably) quote and were recognisably superior at getting back to use and dealing with our queries till we were ready to order. The delivery was on time – the MD personally undertook that, which was a nice touch.’

‘I have to say the quality of the product is absolutely superb and we are very happy with it!’

‘However, what stood out to us was the service we received – post delivery. From sales to technical support – the standard of service has been second to none. I don’t usually spend time with online reviews but I made an exception in this case as I was so pleased with the product overall that I decided to post a review. We needed a lot of technical help installing (we chose to install ourselves) and the team were always on standby for support – on one occasion the technical manager even called me back from the isle of man, even though he was on another job!’

 ‘It would have been helpful for me if the product came with instructions for those how can not afford Renka’s installation fee, but in hindsight, if I had to do it all over again, given my experience of the service I have received from Renka, I would have chosen them to install it. Renka is not a big name in London, but they will certainly stand out to me going forward and i would highly recommend this family run business, whose forte I would say is not just the quality of their products, but the customer care they provide with it, before and after delivery, which to me is as important as the product itself. ‘

‘I wish Renka every success!’

Steve Wallace, Birmingham

‘ Some of the nicest workmen I’ve ever dealt with in all my years in the game – nothing is too much trouble.
