Painting & Decorating- 24 Feb 2020
Quite literally the worst tradesman I have ever worked within 25 years as a property developer! He came and quoted to paint my house (a good price I must say), little did I know that this meant he would spray everything that he can see, not prepare the surfaces by sanding them down or protects things. This included door handles, hinges, radiators, alarms sensors, tiles and my own furniture and cooking utensils. First time I confronted him about this he said that we would clean everything, and we agreed to carry own. However, it became apparent that we was doing the same as previously discussed. have paid hi 66% of what was agreed, I quickly realised that the damaged he has caused was going to cost me far more and I told him to leave. The next day he turned up at my house with his wife demanding the balance which I refused to give him, they were both shouting outside my house, threatening to call the police. I eventually agreed to pay the 50% of what was left, just so that they would leave. However, even once he had confirmed writing his acceptance of this, he walks over to me and threatened me one final time, saying that he will take me to court etc, there is god and he will see to me! I advise to stay away from this person, better to pay a little more and work with professionals who don't agree with one thing and do another. He paints using a spray, which means you can not touch anything up and he quite literally paints everything he sees!!

Roofing (Flat)- 24 May 2026
Martin came and saw the job promptly. His quote was a little more than another I had had but he made a couple of suggestions and generally demonstrated he knew what he was talking about so I chose him. The job was done quickly and well in a day. It hasn't rained heavily yet but the roof seems perfect. Martin did say that if there were any problems to call him. I am sure everything will be fine but it's nice to have that kind of customer service. Highly recommended!

Extensions- 11 Oct 2023
We recently completed an extension at the rear of our property, along with a kitchen renovation and refurbishment of our reception hall. Abdallah and Hesham were instrumental in this project, providing us with a comprehensive work plan. Their labor costs were exceptionally reasonable, and they demonstrated unwavering dedication to the job. Their hard work was evident throughout the project, not only in the construction but also in coordinating plumbing, electrical work, and kitchen fitting through their skilled team. Abdallah co-ordinated well with building regulations, ensuring that our project complied with all the necessary standards. What truly stood out was their flexibility and willingness to adapt to changes and adjustments, especially when dealing with variations in material sizes. This adaptability greatly facilitated the project's progress and success. Thank you Abdallah and Hesham.

Extensions- 8 Oct 2018
Alban completed a lateral kitchen extension for me in west London. Very happy with the results and to add my name to others that have given 100% positive feedback. What I particularly liked - (1) Alban took great care to protect the rest of my house while working (protection, covers etc), (2) his team were friendly and polite to neighbours. Building works are always noisy and disruptive, they kept others 'on side' and (3) they worked to the timing and schedule agreed (4) they cleaned up, every single day (5) they worked to a high standard and corrected for any issues, despite my inevitable last minute changes. Wish him and team best success... happy to recommend. Rob

Kitchen Fitting- 17 Nov 2025
We recently had our kitchen refurbished by Dumitru, and we couldn’t be happier with how everything turned out. He’s one of those rare builders who combines professionalism with real care for the details. He worked efficiently, kept the place tidy throughout the project, and always cleaned up after himself — which honestly made such a difference when living through a renovation. What I appreciated most was how supportive he was when it came to choosing the right materials. He guided us through the options without ever pushing, and his advice proved spot-on. The final result is exactly what we hoped for and more. If you’re looking for someone reliable, skilled, and easy to work with, I totally recommend Dumitru P.S. For anyone curious about the scope of the work: Dumitru changed our worktop, removed the old tiles and redid the flooring with laminate, installed a new cooker and hob, fitted a new sink, repaired the walls after the new boiler went in, and repainted everything. Top work
