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!

I had a commercial property converted into 2 one bedroom flats. Akam builders did an A-class job. The work was done to a very high standard and within the time scale stated by Gurwinder. I was impressed by the extra work he did without any extra charge. This builder is a genuine and reliable builder. The work is in perfect condition after 6 months.

Completed Side extension and 6m rear extension last Oct. Overall happy with the work. Digging, foundation, Bricks, structure, insulation, Roofing, Tiles, plumbing, flooring, painting, etc were done to good standard. Some of the minor corrections, changes or fixes needed near completion were done accordingly. Quote was in midrange and reasonable compared to compared to some others I received.

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez
