Extensions- 2 Oct 2024
He did the extension well, brick work is good, rendering on front of house good, terrace and wall with the neighbours good ,toilet under the stairs good, dividing wall in the living room with sliding doors good, kitchen installed good. Fence wall in front of house good brick work wrong bricks but it’s ok. Herringbone parchet wrong with gaps and lifted, rendering on the side of house wrong with marks, the new boiler took 2 months to make it work and the radiators still don’t work. Electrical work bad, after bringing another engineer to check we discovered at the boiler live cut cables that were loose and veri dangerous. Took 4 months to finish job we waited one month for the plumber who either way did a bad job. Laurentiu did not finish the job because of plumbing and rendering, and we ended in bad terms, he left us money to compensate for it. I would recommend him for extensions and any brick work, he needs to improve in pluming, electrical, flooring and rendering.

Please avoid this company for many reasons. There work is absolutely shocking and the owner is incompetent and should be ashamed of himself how he left my job. I’ve tried to contact Elijah and he’s blocked me, he’s an absolute disgrace. I will put up pictures of his work so you can see how bad his work is.

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

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Vladimir did an excellent job. The base of my decking was completely rotten and needed a full replacement. He built a new base and reinstalled the decking on top, explaining everything clearly along the way. The work was done to a very high standard and I’d highly recommend him.
