Extensions- 14 Dec 2017
Rob and his team were great! Without hesitation he gave us 3 references of extensions he had built locally to us all with glowing appraisals before we confirmed we were happy for him to start. He explained everything very well and was always reassuring. His timing keeping on our project even with small problems were spot on and actually finished 2/3 days before the agreed finished date. Rob and his team also supported us when we had issues with suppliers (which we sourced). Rob and his team were always polite, friendly and willing to chat over the phone at pretty much anytime. He have a dog and he was always very considerate of him during the build. I would highly recommend Belmax team and their 5 star work/service.

Architecture- 27 Nov 2017
I contacted Marius because he had good reviews and wanted someone reliable and capable so design a single story extension with large external and internal bifold doors. I wasn’t disappointed - Marius has been excellent throughout the whole design process and produced drawings to a high standard which met our requirements. Marius was an excellent communicator and always available to give advice when required. Further more, he went out of his way to contact local authorities regarding any questions I had at no extra cost to clarify any uncertainties. I would highly recommend his architectural services - he was good value and very professional.

Bathroom Fitting- 26 Jul 2024
Catalin completely transformed both bathrooms! He listened to our requests and has come with good solutions to our problems, including recessed shelves and replacing the hot water cylinder with a combi boiler, to give us more space in the bathroom. The work was done to a very high standard and has helped us to source materials and sanitary ware. Catalin and his team has done a fabulous job! I highly recommend him!
