Restoration & Refurbishment- 31 Jul 2023
We put the ad up on Saturday morning, Ed popped over in the afternoon and gave us a quote and the job was completed on Monday! Super quick process. For a job that was causing us stress and we quickly realised we couldn’t do ourselves, Ed came in and sorted it really quickly as well as giving us advice on next steps for our redecorating. Will be contacting again when we need further help!

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 engaged Edi to work on a full renovation and refurbishment of a 4 bedroom detached house with front and back gardens on Blackheath’s Cator Estate. Edi did an extensive amount of work, including stripping out; plumbing; plastering; windows installation; carpentry; and decoration. In addition, after commencing the property work, once the scaffold had been erected, following sensible advice, Edi and his team replaced the roof and fully insulated the attic; fitted additional electric points; rebuilt the garden patio; and replaced the flooring throughout, in addition to other important jobs including re rendering and pointing of chimneys, building new wardrobes in the main bedrooms; and upgrading the radiators. A new kitchen, and two new bathrooms have been fitted. The kitchen redesign meant knocking through a wall with the lounge to create a larger space. Edi is a highly skilled craftsman, who thinks creatively as he works to make best use of the space, including shelf fittings, and additional lighting for example. He has built some beautiful wardrobes, and the internal decorations have brightened up what was previously a rather shabby looking house. In addition to the above, I wish to commend Edi for his professionalism, courtesy, and passion for doing the best work possible. On all the site visits I attended, and every time I spoke with him on the phone, it was striking how much he cared about the work that he was doing, his desire to ensure that the house would look the best. I always left site visits with the feeling that he cared so much about the house that he could be safely relied on to give the best advice to enable us to make the right decisions. I also noticed that Edi and his team would take the upmost care to keep the property safe, tidy and in good shape throughout the project. He can be fully trusted to look after any site he works on. He is intelligent and careful when it comes to safety and security. It has been a pleasure for Edi and his team to work with us over a period of around 6 months, and he did so much to reduce the stress of a significant project so that we could always rely on him to work methodically, patiently and sensibly, and to make best use of the resources available. His pleasantness shines through, and everyone I know who has spoken to him has always provided me with the most positive feedback I have no hesitation in recommending Edi to anyone who wishes to engage him for future projects, and is most deserving of the good words that I and others that work with him have to say about him.

Bathroom Fitting- 1 Jun 2025
I am really pleased with my new bathroom. I needed a partial refurb and new flooring due to a previous leaking shower. Landi did a great job fitting new taps, shower and sink in my bathroom. He was also able to advice me on the best sink and radiators and helped me to choose the right fittings when I was ordering. I didn't like the colour of the sealant and he redid it in another colour with no issues. He was efficient, friendly and completed the job in good time. Communication was always swift and I would be happy to recommend him to others and use him again for other jobs. Thanks Landi for great service.

Great, reliable contractors. Had a full flat repaint job with some minor repairs (blinds fixing, handle replacement). Claudia was very efficient and responsive in communication. All was arranged pretty quick, appointment attended on time and kept to time schedule agreed. Had done a great job with repaint and provided reasonable rates. Also helped out with few minor repairs so I didn't have to get someone else. Very happy with the service , will certainly hire again. Thank you guys.
