Bathroom Fitting- 24 Oct 2025
We had 2 bathrooms refurbished at the same time by Romulus and his team over a 4 week period. Both bathrooms were completed on time and on budget. We were looking for 2 functional bathrooms, but ended up with 2 very high spec bathrooms within our original budget, and couldn't be happier with the high level of service and professionalism by all his team. We will now move forward and have his team refurbish our kitchen.

Extensions- 23 May 2022
Ceca Developments have done an outstanding work on our side and rear extension project, and we would definitely recommend this company. Firstly, they have offered a really competitive quote for the work and have been very transparent and detailed in regards to how long it will take to complete the project. Sebastjan has been a pleasure to deal with and was very helpful during the project, providing honest and useful recommendations and being available every time we needed anything. All the work has been completed to a very high standard and to the agreed timelines. We did not have to worry about anything during the whole project, which made this a very pleasant experience.

I originally contacted Joe from Orama to fit a new kitchen for me. When he came to give me a quote, I hadn't yet chosen what I wanted. He really took the time to make several recommendations and so I decided to go ahead with him to design my kitchen fully and fit it. The team were so easy to work with and most importantly respectful in my home! Their attention to detail is second to none. He really understood the style I liked in one conversation. The finish is flawless. I highly recommend them!!
