Extensions- 11 Jul 2018
Graham removed a lean to and replaced with a large brick extension to the back of the house and we are so pleased we hired him. The work started and progressed as expected and through the awful spring weather too! He finished look is great, the building inspector was really pleased with everything and as soon as had completed the extension we asked him to rip our old porch down and build a new one and luckily he had a week spare before a new job so cracked on with this too straight away. We would recommend Graham, he was hard working, tidy and just got on with it!

Red 4 developments limited
Rating: 5 out of 5
Extension Builder in Newcastle Upon Tyne
At Red4 we are a genuine Family run business with over 20 years experience in Windows , doors, conservatories, warmroofs and more. We aim to always provide a first class personal service with top quality products. Having worked for the big local companies I (Michael ) decided the time was right just over two years ago to set my own business up and do things my own way the right way . From small repairs to full extensions we will always make sure every customer is as important as the next. We don’t have salesman so the person you speak to on the phone or at your door will be the one surveying/ installing and doing the work . It is also very rare we would give a quote at point of contact however most quotes will be back to the potential customer within 24 hrs. We aim to give you our best quote first time. When you choose Red4 you can relax in knowing you are working with a trusted family firm, who really cares.

Extensions- 26 May 2026
Michael and his team completed a fantastic orangery for me. Michael’s attention to detail is amazing and communicated well throughout the whole project. The brickwork was completed by Jason and his team and the job they done was fantastic, clearing all rubbish as they went. Michael then completed the roof and bifold doors. This addition to my ground floor flat is fantastic and will improve my life massively. So a huge thanks to Michael and Jason especially, and the rest of the team that got involved. I would recommend Red4 developments to anyone. Thy are fantastic. I certainly was lucky to find such professional and fantastic guys to complete this project. All the best for the future guys. And thanks again for the amazing job you have ☑️
