Painting & Decorating- 19 Jun 2024
I recently had the pleasure of working with Mahdi and his team, and they were excellent. They were knowledgeable, did the work efficiently, and cleaned up thoroughly afterward.

Bathroom Fitting- 7 Jun 2026
We recently had our bathrooms refurbished by Vasile and his team, and we are absolutely delighted with the results. From the very beginning, they were professional, reliable, kind, and exceptionally helpful. Vasile was always available to discuss every aspect of the project, taking the time to explain things clearly and answer our questions with patience and honesty. It felt as though we had a genuine partner supporting us through the renovation of our three-bedroom flat. Vasile and his team were fully invested in achieving the best possible outcome and were always willing to go the extra mile when challenges arose. The quality of their work is outstanding. They worked efficiently, kept us informed throughout, and ensured everything was completed in a timely manner without compromising on quality. We would wholeheartedly recommend Vasile and his team to anyone looking for skilled, trustworthy, and genuinely caring professionals.

Extensions- 25 Aug 2021
Having had bad experiences in the past with other builders, this time we tried to do our homework properly before hiring someone. We couldn't have chosen a more competent and professional builder! We obviously asked around and had many quotes (some ridiculously expensive, others didn't even seem to understand what we wanted to do) but Sorin immediately impressed me with his detailed and fair quote, knowledge and lots of suggestions (he's the kind of guy that immediately gives you the impression that he knows what he's talking about). We encountered some issues during the works (which is to be expected if you didn't build the place yourself) but Sorin and his team did an amazing job and always gave us regular updates. End result? Work completed on time and a new construction that is exactly what we asked for (plus other things here and there that he kindly sorted while he was on site!)

Handyman- 12 Oct 2018
The flat was left in a very bad state after the tenants left. Marius was able to undertake all the jobs, from changing carpets, redecorate, repairs and clean up. Also gave good advice as I was not able to attend the site in person so Marius kept me updated with photos. The price was also good. Thank you. Will use these guys again.

Extensions- 29 Aug 2021
Communicated well at the start with reasonable cost. work was done well but the finishing was not so great as expected. The end cost was very expensive. Charged by the hour, the team were very slow which was upsetting to see me pay for time where they sat around not doing much. Ensure to agree fixed price. Communication after job is poor, double glazing has warranty which now not being able to communicate with kostas having to pay to get things done that should be covered in warranty. Central heating give huge problems. Do not use for big jobs

Tudor did a great job on our kitchen. He kept us informed on progress all the way through the job allowing time in the morning for questions and then getting on with the work during the day. At the end of each day he showed us and spoke with us about the excellent progress he had made. Very pleased with our lovely new kitchen which is clean, bright and spacious.

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.

Kitchen Fitting- 23 Dec 2025
I recently had my kitchen fitted by O&J Constructions LTD, and I couldn’t be happier with the results. From start to finish, the job was carried out exactly as agreed, with clear communication and professionalism throughout. The attention to detail was excellent. Every cabinet, worktop, and fitting was installed neatly and securely. The project was completed on time and exactly as outlined in our agreement, with no hidden surprises. Ahmed was courteous, punctual, and kept the workspace tidy each day. My kitchen now looks fantastic and functions perfectly, making it a real centerpiece of my home. I would highly recommend O&J Constructions to anyone looking for a reliable and skilled professional for kitchen fitting. The whole experience was smooth and stress-free, and the final result exceeded my expectations.
