Robert Jaynes,

South Wales

We used RGB construction for a garage conversion on our home. We had no experience with building works/conversions etc. but Rob was brilliant from start to finish explaining all that would need to be done and explaining fully all aspects of work before we committed to the job. We chose Rob as he presented a professional, knowledgeable approach. We were not disappointed. The work was completed incredibly quickly and we were kept up to date throughout. The building inspector was dealt with by Rob too and he made sure we received the necessary paperwork to show it was completed to the necessary standards. Despite being a big job Rob kept the house and surroundings clean at all times ensuring that our two little ones were protected throughout the works. We are delighted with the finish and our children now have a wonderful space of their own to play. Even after completion Rob stayed in contact to ensure everything was in order and working correctly. I would definitely recommend RGB construction and would not hesitate to use them again. Thank you RGB!


Jane Williams,


My double story extension was quoted in April and finished in June! The service was impeccable, Rob and his team worked tirelessly to complete what I though was unimaginable before our baby was due! Great finish in a small time-frame and what was even better was how personable the service was! Thanks Rob, very much appreciated! Have already recommended to friends and family! Kind Regards Jane, Gareth and baby George


Michael Rawlings,


Had Rob in for extensive work to our previous property. We had an extension to the side of our house to extend the living room and he converted our garage into a playroom. He also installed a new kitchen and refitted all of the bedrooms in the house. All work was to an extremely high standard. The wife and I were over the moon with the results it was better than we ever imagined. Rob was professional throughout the full renovation and always reliable, clean, tidy and respectful. He was up front and clear on pricing which made the process stress free. We always knew where we stood. Can’t recommend highly enough. We will certainly be getting him back to our new house in the future.


Liam O'brien,


I had Rob in my house to install skirting boards in 3 of my bedrooms and outside fencing along my driveway. 
All work was done to a very high standard, and RGB were very clean and approachable. 
Happy customer. 
Highly recommend.





RGB Construction did a fantastic job converting my garage into a habitable room. Besides the quality of the finished room, what impressed me was the fact that the job was completed in the time originally estimated and there was no budget creep. Rob was hardworking, knowledgable and trustworthy. I would not hesitate to use Rob again and I highly recommend him.



Excellent work carried out on 2 properties. Standard of work amazing, friendly and helpful team. I will definitely use again and will recommend their services to my friends and family. Thank you Rob and team.



Excellent! Extremely happy - Rob came today to hang 3 doors for us. We are very happy with the job and will be asking him to do more work for us in the near future. Highly recommended!


Andy Clode,


We have had Rob and his team over a few times for general maintenance. As a company they are on time, clean and very reliable. We are at present going to have a kitchen extension with RGB Construction and can’t wait.
