I recently had a full kitchen installation carried out and I’m really pleased with the results. From start to finish, the work was completed to a high standard and everything was done with great attention to detail. The installer was professional, punctual, and easy to communicate with throughout the project. Any issues or questions I had were dealt with quickly and clearly, which gave me confidence that the job was in good hands. The workmanship is excellent – everything is level, neatly finished, and exactly as discussed. They also kept the workspace tidy each day and made sure everything was cleaned up properly once the job was complete. The kitchen looks fantastic and has completely transformed the space. I would happily recommend them to anyone looking for a reliable and skilled kitchen installer, and I would definitely use them again for future work.

Painting & Decorating- 1 Jul 2017
I would highly recommend these guys. They did a very high quality job decorating my lounge, dining room, hallway and stairs. They started the job on time, worked through the weekend to get the job finished in good time, left the place clean and tidy at the end of every day, and cleaned up immaculately at the end of the job. The price was also very competitive compared with other quotes I received. I hope they are available again in a few months time when I have more decorating that needs to be done.

Extensions- 25 Apr 2020
Financial restrictions meant we had to change from an extension to simply improving the existing house. I gave Vlad a call on a friday and his army was ready to start the very next Monday morning. All would have been finished in less than 2 weeks but the unexpected Covid-19 lockdown on 23rd March meant that supplies were harder to get. Very pleased with our brand new house. Good job done on new Electrics, Kitchen, Bathroom and plumbing and he even helped fix our D.I.Y furniture at the end. Will definitely use VM on our next project.

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.
