Extensions- 9 Nov 2021
I had a great experience hiring Victor & Co. They built a Rear Garden Extension in my house with excellent standards and finishing. Also they have done everything on time, which I know is quite difficult. I met Victor, the director of the project, every week to discuss the progress and any alterations to the original plans. He was great at explaining all the options and delivering the work. All the builders were very polite and you could see that they were very well organised with all the tools and building materials they brought to the house. When there were minor delays they were happy to come on weekends to catch up with the programmed finishing time. For the level of noise you could expect a building site can generate they were incredibly quiet. Last and not least, the quote I have from them was one of the most competitive ones I found in the market, so I can definitely recommend this company to anybody that is planning a big project.

Extensions- 2 May 2018
Tom is a very competent builder, who has attention to details. Tom continuously went out of his way to find ways to meet my requirements, Whenever we had atypical challenge during my extension Tom's default position was "let's find a work around." He was creative and efficient in doing so, and most importantly cost effective, as I was running on tight budget. Fantastic experience working with Tom, he estimated the work to complete in 6 weeks, the work was done 5 and a half weeks and handed over. The works speaks of itself, very urban finish with high level of professionalism. I was almost hands off the project due to work travel, and Tom took care of all the aspects without me being involved day to day and micro manage. He is surely being to be big league builder in no time. I would recommend him whole heartedly.

Extensions- 26 Apr 2018
Professional Polish builders (london) ltd,?this is a suitable name for this company. They built an extension and loft for me in the time standards set. They aren’t a cheap service but the professionalism of this boys goes beyond and above. I’ve seen a lot in my life and it was the third extension I designed for myself as I’m architect. It is hard to find an honest builder who will tell you the truth about what is waiting for you during the works. The job was done relatively quickly even when I changed my mind a few times and the weather this winter was cruel but Adam and Martin were always positive so do not believe any one who gives a fixed price and time - it’s impossible to do. Adam and Martin are fantastic organizers and skillful professional builders, his team are friendly,very funny and hard working guys. Open minded guys who will tell you straight on what things you can save money on and what not to. My dog has fallen in love with them. Safety and common sense is a priority to the crew. I would recommend these boys to everyone. thanks for your help and hard work!

Extensions- 15 Jun 2024
My advice is avoid. Poor communication Poor workmanship Poor quality finish Create 'issues' during build to make you pay more than quoted Left project incomplete We pursued through the Court and won the case, but of course he is unable to pay, so we are pursing further through the Court. He will respond to the review with some excuse, but there is absoultley no excuse for poor workmanship and quality. Happy to share pictures and videos on request.
