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.

Bathroom Fitting- 22 Apr 2023
Younger brother Anti was a professional and I would hire again but beware of the elder sibling as his workmanship his poor, here is a list:- 1) the cupboard fitted under the stairs was misaligned and the hinges are loose. Paint job was poorly finished too. 2) cupboard fitted across the boiler was all bent. Anti came and fixed it. 3) varnish across door and skirting boards were done once and therefore have an uneven spread 4) the floorboards did not have enough glue placed in certain areas so it creaks 5) grout in some time are missing 6) really poor sealant work on the bathroom 7) broke my £2000 TV and then hid the evidence. I only found out after placing the furniture back in its place. In contrast Anti did a good job in fitting the radiator. If you can Illicit promises of Anti only completing the job without the older the brother then go for it or else give them a wide berth.

Extensions- 2 May 2018
Tom is a very competent builder, who has attention to details. Tom continuously went out of his way to find ways to meet my requirements, Whenever we had atypical challenge during my extension Tom's default position was "let's find a work around." He was creative and efficient in doing so, and most importantly cost effective, as I was running on tight budget. Fantastic experience working with Tom, he estimated the work to complete in 6 weeks, the work was done 5 and a half weeks and handed over. The works speaks of itself, very urban finish with high level of professionalism. I was almost hands off the project due to work travel, and Tom took care of all the aspects without me being involved day to day and micro manage. He is surely being to be big league builder in no time. I would recommend him whole heartedly.

Converting your loft into a beautiful living space may seem like a daunting task, but the results are always going to be worth the painstaking process. The loft conversion procedure does not have to be that difficult; all you require is to hire right people to do the right job.

I hired Nikolay and his coworker to build a small walk in closet. The job was done properly and they delivered what was promised in the estimated time. They also left the house tiny and clean. It was a nice experience. The price was also really good.
