We engaged Rainbow to renovate our shower room. Very, very easy to work with - helpful with advice and support about what we needed to get done. Mark and Max were great - you couldn't ask for friendlier people. We had some teething issues (NOT the fault of Rainbow) which Rainbow helped to rectify and get the job complete. Recommended and we'd certainly use their services again.

We went to Rainbow building to get some work done in our kitchen before we could get a new kitchen fitted in. They did wonderful work and let us know of any issues or complication we would face. Mark and Max especially were really nice and we're really happy with the partial wall removal, tile removing and replastering work they did for us!

The Rainbow team first did some excellent work for us 10 years ago. And they have just finished some renovations in the last week, which has gone really smoothly. Kev is a great communicator, always able to offer his expert opinion on the work required and then gets the job done. The best in Brighton.

Needed a complete flat refurbishment to include new Kitchen, Bathroom, Flooring, Electrics, Plumbing and Decorating etc. Wanted a local contractor to take control of the whole project rather than trying to juggle lots of different Trades myself. Rainbow (Mark in particular) were able to manage the whole project from start to finish and totally transformed the place, as shown in the photos. I was particularly impressed with the Kitchen so a special shout out to Stephen

We had a great experience with Kev, Mark and their team. Our bathroom was gutted and then totally refitted, and the result looks brilliant! They were really communicative throughout the process, offered recommendations, and worked hard to resolve issues which popped up. Would definitely recommend. Thanks so much!

We’re absolutely delighted with our new bathroom. Kevin, Mark and the team transformed an old, tired space into a clean, modern and relaxing room that’s a real joy to use. There were a few unexpected challenges along the way, but everything was clearly explained and managed, so there were no nasty surprises with the budget. They were also very considerate of our circumstances at home, which made the whole process much easier. Professional, tidy, and great communication throughout – highly recommended!

Steel Beam Works / Plastering / External Render / Carpentry / Window Fitting We have used Rainbow several times over the years and always had excellent workmanship. This was our biggest work and we were a bit nervous but Mark and the boys were extremely capable, curteous and considerate. We were living on site and they did their best to mitigate dust affecting our living area. We also didn't have to endure a radio playing the same music again and again! They were also very reliable. Now they have gone, we actually miss them!

Friendly, reliable and willing to take on smaller jobs as well as larger ones. The work was of a high standard and communication was clear and simple. I wouldn’t hesitate to happily recommend Rainbow and will certainly use them again in the future.

From the very first on-site meeting with Kevin Viney at Rainbow Building Plumbing & Electrical Services we were confident in the advice given, and suggestions made. Major building renovations are a daunting task, so with Rainbow we felt we would be in safe hands if we engaged them. And we weren’t disappointed. Throughout the project those things that were most important to us were achieved, many requiring precision down to the millimetre. And when unforeseen issues arose, as they do in older buildings, whilst these caused us some sleepless nights, Rainbow confidently dealt with them enabling us to return to calm and carry on. Mark Burns, the builder and project manager, has been amazing with his wide knowledge, craftsmanship, and meticulous attention to detail - and his calm manner under pressure, has resulted in every aspect of the work carried out by Rainbow to be of a high standard and the best it could be. Thank you Rainbow - and if ever we are crazy enough to embark on another renovation project we would definitely be calling you to see it through.

Rainbow have carried out a complete refurbishment of my flat to an impeccable standard. They also landscaped the garden. Both look unrecognisable and I wouldn't hesitate to recommend Kev, Mark, Steve and the others at Rainbow.

Hi there - we have just had our kitchen fitted by Rainbow, and I would heartily recommend them to anyone else in Brighton. They were super organised, friendly and easy to communicate with, got the job done quickly AND it looks really good! Definitely good value for money as well! Cheers Danny

A trustworthy and responsive Building Company? Yes, it is rare but Rainbow fits the bill. Kev and his staff/contractors know their stuff. Kev was always responsive and reliable when contacted - a big plus in my book - and his workers left the place as clean and tidy as possible after a major structural work. Definitely recommend

Structural Alteration FAQs

Do I need building control approval for wall removal?

Yes — if the wall is load-bearing or structural. Rainbow coordinates with engineers and Building Control to ensure compliance and safety.

What is an RSJ and do I need one?

An RSJ (rolled steel joist) is often required when removing load-bearing walls. We'll assess and install the right support to match your plans.

Can you handle engineer coordination?

Absolutely — we work with trusted engineers or can follow drawings supplied by your own team to execute the structural plan safely.

How disruptive is structural alteration work?

We use dust control, structural props, and smart scheduling to keep disruption minimal. We also tidy and clear all waste as we go.
