Amazing job and a brilliant team of tradespersons. An excellent job of the herringbone tile flooring with underfloor electric heating for the whole of my downstairs. The wall panels also complemented the flooring and were installed perfectly. Well done to Bujar and his team!

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.

Extensions- 2 Nov 2018
Building a 2 storey rear extension and hired Jamal to do the Block work. Initial ground storey heavy Hollow block walls for the 3 x 3m extension completed in only 3.5 days by Jamal himself with no extra help. Hardworking young guy. I was nearly bedbound with sciatica and in great pain and he immediately offered to source and buy on my behalf extra blocks required to relieve further stress on me. Very helpful, reasonable and understanding. Explained anything I asked him diligently. Knows his job and I will be calling him back when I have the money to complete the block work for the 2nd storey.

Restoration & Refurbishment- 27 Aug 2026
Charlie and his team took two rooms back to brick and rebuilt them from scratch: new floor, plastering, ceiling and coving. Fantastic job throughout. Great workmanship, good communication, and they kept the site clean and tidy. They started promptly on the day agreed and finished within the timeline they’d quoted. Would happily recommend them and hope to use them again on future projects. Thank you!
