Painting & Decorating- 8 Jan 2026
Great job done - Bulent was quick to communicate and efficient in getting everything finished. He was careful to ensure a high standard of finish and I am very happy with the result. He even did extra bits like sealing our bathtub on top of the painting requested.

Bathroom Fitting- 26 Aug 2026
We found Vadet to be a very thorough, hard-working, precise and reasonably priced choice. Vasile himself is a good communicator and throughout the job, he pointed out different options as they cropped up, and the costs they'd incur. I know this is to be expected, but he did it well.

Extensions- 18 Sep 2024
I looked at 5 quotes and was so happy to have chosen Elvis and his highly experienced team. They did an excellent job of building a new 11sq meter garden rear extension. This was a bit complicated project because it’s a listed house. Elvis and his team were hardworking, always responsive and came up with great solutions when necessary. I am very pleased with the high quality end result. I would use them again and can't recommend them enough! Great job done

Restoration & Refurbishment- 2 Aug 2025
Asen did an incredible job! In just under 4 weeks he managed to assemble a team and complete renovation on a 2 bed flat including: * Full rewiring, new lights, updating and adding sockets * Fixing rotten and uneven subfloor and levelling the whole house * Wood flooring throughout - done excellently with no thresholds * New boiler and all new radiators * Built a pocket door at the porch to stop our kitties from escaping * Tiled the fireplace * Skirting, decorating and repainting the entire flat * Dealt with gutting the place and arranging pickup of rubish The place looks and feels amazing and everything works! Asen was good on the price, kept to the (very tight) timelines, great communication throughout and overall very professional and friendly! Pics shows after and during the work, ignore the moving boxes.

Restoration & Refurbishment- 16 May 2021
TLC have completed the first phase of the project which has involved a complete renovation and upgrade of the kitchen, bathroom, and rear garden area. A new contemporary staircase has also been fitted. The work has been completed well ahead of schedule, and this is testament to the planning and coordination skills provided by TLC. All of the work has been completed to a very high standard, and a great deal of care has been taken to ensure the minimum disruption to the local residents. We are extremely grateful for the advice and support provided to us leading up to the restoration work and whilst the restoration was underway, and we are absolutely delighted with the final results. Our house has been transformed into a contemporary family home. Many thanks to Bradley, Paul, and the rest of the team at TLC.

Plastering- 4 Oct 2024
Mr Rifat did an excellent job for plastering rooms and i would recommend him to everyone highly. The work he has done is to a very high standard and completed in 3 days. His quote was very helpful and comprehensive and he was helpful and very kind and calm. He did not take a break from doing the work, even though i told him to take a seat for 5-10 minutes. He is a very hardworking person. I think anyone to catch him to do a job for themselves is very lucky. I recommend him to everyone because he knows how to do good job.

Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.
