Had Bi-folds fitted & Structural works to remove existing pillar and install new Steel, Really good service, doors are fantastic quality and workmanship of the doors and installation from the builders was very impressive, really tidy and professional. Would definitely recommend.

Michael Deans

Really pleased with our doors and windows. A very friendly team, with great customer service. Very neat installation of back door and window, French doors and side windows, and numerous other windows. Very close in style to the old single glazed wooden-framed doors and windows they replaced, just as we had asked. Would definitely recommend.

Sarah Winning

Replaced a bay window with lovely bifold doors. Quick installation, quality and friendly workmanship, good customer service and regular updates. Best quote I could find in the area too. Really pleased, thank you.

Amy Elizabeth Madden

The doors are fantastic – a lifestyle changer. You can trust these people and their products – the post-installation service separates Riverside from the competition. In my humble assessment, following a lot of research, Riverside will still be in business when much of the competition is no longer around. My thanks to Aaron and his team.

Tony FitzPatrick

We regularly use the team at Riverside for both uPVC and aluminium bifolding doors on our projects. We have always found them to be extremely helpful and knowledgeable.

It’s especially important to us that their products turn up when they say they will, and we have never been disappointed with the quality or price!

Ian Young

We are delighted with the quality of the doors and also the professionalism of the two guys who did the fitting.

I have no hesitation at all in recommending Aaron and his team.

Martin Dawson

I highly recommend! The team are very helpful, and the doors look fantastic and are of great quality. Prices very competitive and much quicker time to install than other companies I contacted. Very pleased!
