Bathroom Fitting- 24 May 2026
We hadn’t changed my Mum's bathroom in 30+ years, so it was a massive job. We definitely made the right choice with this team. Every step was so well planned, and they worked incredibly hard so mum could move back in on time. Everything was changed and updated, and it looks absolutely beautiful now. Laurentiu and his team are so patient, taking the time to talk through various options and their attention to detail for the perfect final finish was spot on. Every little corner and tile looks brilliant. They take great pride in their work. If you're thinking of getting your bathroom done, definitely use them. They are lovely to work with and you won't be disappointed. Highly recommended!

Bathroom Fitting- 28 May 2025
I am extremely happy with the job Isac has done. We are so very lucky to have found Isac to do our home. At the time of the works we were expecting a baby and Isac worked night and day to make sure our home was ready in time for our sons arrival. Without him we would have been screwed. Isac’s work is extremely professional. He has high standards and is very skilled. He’s honest, direct and respectful. I now consider Isac as a friend. He’s come back a few times since the works to check in and is always on the phone is you have any follow up queries. I would recommend Isac to anyone who has work they needed done. Thank you Isac!!!

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

Carpentry- 24 May 2026
Antonio and his team were absolutely outstanding. They arrived every single day punctual without fail, worked incredibly hard, and delivered exactly within the timeframe they promised. Their professionalism and care stood out from start to finish. They transformed my parents’ staircase beautifully, bringing it to life with real craftsmanship and care, they even managed to add in a under stairs cupboard which we didn’t even think of at first to utilise some of the empty space. They made sure to clean up thoroughly each day, which made the whole process so much easier for my parents. It’s rare nowadays to find tradespeople who are this reliable, trustworthy, and committed to such a high standard of work. We couldn’t recommend them highly enough, and we’re already looking forward to having them back for future projects. Thank you again Antonio🙏🏼

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.

Restoration & Refurbishment- 29 Mar 2018
A pleasure to deal with . Agim and his team worked hard to a very good standard.They often worked later than i would expect so that they were ready to move onto the next stage of the job the following day. Agim was very knowledgeable of all building regulations and was ready to offer me solutions when they were needed. All his team were courteous , polite and also knowledgeable. This was the first time I have used A&B but I would have no hesitation of using them again and recommending them to others.
