Restoration & Refurbishment- 18 Feb 2021
Ray was an absolute professional. He fitted a new downstairs toilet which required a new soil pipe and associated groundwork as well as new stud walling to partition the space. He did most of the work himself, but brought in others for the pieces where he wanted an expert. He was flexible to small changes and was happy to take on additional work when unforeseen issues were discovered. The areas he had worked in were quickly cleaned before he left each day. Overall the work was completed to a good quality and at a reasonable price.

Electrical- 26 Jul 2026
Genuinely one of the worst builders we have come across. David rewired the flat and Stefan plastered the hallway. David is NOT qualified as an electrician and cut corners wherever he could. David leveraged us for money mid job and in the end left the job without finishing and without providing a certificate. David ran cables behind door frames (awful idea), got the cheapest material, forgot where holes were for spotlights and switches among many issues which meant we had to constantly ask our builders to fill the holes and make good. Stefan did the hallway plastering without putting on mesh. The plaster cracked within 2 weeks and the paint keeps cracking and will be a constant problem. When asked to come back and fix the issue - he point blank refused. They were the cheapest quote but we really hope we had gone to someone else

Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!

Joinery & Cabinet Making- 20 Jan 2010
Ceka Construction fitted new skirting boards and picture rail aswell as removing the current skirting board first. From start to finish the service was Excellent. They responded back to any question i had very promptly and the quality of work carried out was of an exceptionally high standard. Roland was very flexible with his time to get the job done with my timeframe requirements and the Carpenter Vini worked fast, of very high quality and cleaned up afterwards. I would highly recommend Ceka Construction to anyone as they were completely professional and reliable.

Extensions- 11 Oct 2023
We recently completed an extension at the rear of our property, along with a kitchen renovation and refurbishment of our reception hall. Abdallah and Hesham were instrumental in this project, providing us with a comprehensive work plan. Their labor costs were exceptionally reasonable, and they demonstrated unwavering dedication to the job. Their hard work was evident throughout the project, not only in the construction but also in coordinating plumbing, electrical work, and kitchen fitting through their skilled team. Abdallah co-ordinated well with building regulations, ensuring that our project complied with all the necessary standards. What truly stood out was their flexibility and willingness to adapt to changes and adjustments, especially when dealing with variations in material sizes. This adaptability greatly facilitated the project's progress and success. Thank you Abdallah and Hesham.

Extensions- 6 Oct 2022
I was lucky enough to have Haroun on this project of side extension and outside building. He is such a professional guy and always committed to do his work up to the standard. He has been very nice to us and always responded whenever asked to do additional jobs. He is very honest and trustworthy and his team has been very wonderful. I'm very happy with work he did in the house and would hire him again should the necessity arise in future.

Extensions- 30 Sep 2020
Bajram and his team did a great job building a utility room extension to our new house and rescued us from a very bad experience with a prior building company. The job was done at a competitive price and in good speed, not because it was rushed but because it was managed very well with enough man power at the right times. I was so happy that I subsequently got them to take on several other aspects of our full house refurbishment.

Plastering- 5 Aug 2019
The job was more than a standard plaster job it was a complete refurbishment of the dining room with the new flooring extending into the hallway. Ionut did an amazing job his attention to detail is first rate I have used quite a few builders over the years and I can honestly say Ionut impressed me the most. He is hardworking, meticulous to detail, tidy and goes above and beyond the job that has been agreed. An example of this was him deciding to hide all loose wiring while he was doing the skirting which has made things much more tidy and also doing new flooring and skirting under the stairs without me asking. He wrapped everything in plastic during the job (radiators, doors, light sockets etc) no plasterer I have used before took that much care in protecting things during plastering which as we know is a very messy job. We will be recommending to all our friends and in the future he will be the first contact if we need any more building work. 100 percent recommend his services and thank you Ionut for the job you have done for us
