Conversions - General- 18 Jan 2023
I found mr. Mark to be a very professional guy. Arrived promptly the next day, had a look at what was required to be done and gave me a quote. The work was done a few days later, as agreed, professionally, done clean cuts within the wall and added a lintle too. It finalised with the pointing over the bricks in the lintle area and left the place spotless once the job was finished. He even reduced, on his own accord, money from the original quote, as the job was done faster than he has anticipated. I will definitely employ him for future works and recommend him whenever i got the chance! Thank you again for your work Mark!

VJ and his team have just finished a full reconfiguration of the downstairs of my house, taking out walls and toilet to make a large open plan kitchen, dining room living space, making a new toilet and utility room in the garage room.

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.
