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.

Extensions- 17 Jan 2018
A Total disappointment Ricky agreed to install a porch and roofing. He advised us to install new pvc doors agreeing to fit the roof after. This started mid November with a promise to be completed before Christmas. On his instruction we paid other workers to complete the preparation works and then the morning of the Job he sent a text message advising that he will no longer be able to attend the job. Thankfully we were able to find a local reputable roofer -plasterer-tiler who completed the work to a very high standard I feel very let down as I had put total trust in his promise to complete the work. Unfortunately based on this I cannot confidently recommend Ricky to a friend family, or anyone else.

Bricklaying- 17 Dec 2024
They initially gave a fair price and a date and timeline that fitted with our needs. Subsequently they over ordered on the bricks so we had over 100+ expensive London bricks left over and they under ordered on sand and cement.(Luckily the shop took them back but we had to deliver them there) The job took far longer than they had said although the poor weather did not help much which could not be helped. The worst was that the wall was finished so that the latch of the gate could not be fitted as the wall was a bit too long! The wall looks good but their customer service and time given for job as well as ordering materials needs some improvements. They are pleasant workers, not rude in speaking

Firoj and his team renovated a bathroom for me in March 2015. He gave me a fixed cost for his labour and what turned out to be a very accurate estimated cost for all the parts/materials at the outset. He also gave me a completion time of 9 days with 1 extra day for 'spillovers' and 'unforseen delays'. He finished the job at exactly 9 days and still came around on the 10th day to see how everything was working. The quality of his work was excellent, to say the least. He attention to detail was admirable, as was his commitment to delivering a finished product that would last several years. This focus on detail and longevity is something that really sets Firoj apart from other builders, who often see such jobs as just another task to be completed before moving onto the next job. I have no hesitation in recommending him. Several months later my bathroom still looks great and everything works.

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 plumbing emergency when my boiler stopped working, so I contacted AM All Building Services. They responded incredibly quickly and were at my property within just 30 minutes. A plumber had been there before them and told me the boiler couldn’t be repaired and that I would need to wait for a replacement. The team from AM All Building Services came out, diagnosed the problem, and managed to get everything working without any issues. The following day, they came back and replaced the boiler as arranged. Their prices were very competitive, and the whole team was professional, friendly, and reliable throughout the process. I’m very happy with the service and would definitely recommend AM All Building Services to anyone looking for a reliable plumbing and heating team. Excellent service from start to finish!

Extensions- 11 Nov 2019
I hired peter of quality first for a single story rear extension and total house refurb in a investment property. After much discussion and advice from peter regarding the costs and Added value, I decided to just do a house refurb, and I can truly say that peter’s input was sound and saved me a lot of time and money. I was able to leave peter and his guys to get on with the job and was extremely happy with the end result. I was kept up to date with progress on a daily Basis and Peter managed to keep close to budget by sourcing materials and appliances from his various reliable sources, sometimes travelling great distance in order to do so. I was so happy with the results that I have used Peter and his team for a much bigger project which is close to completion (on schedule) and will continue to use and recommend peter in the future.

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

Bricklaying- 14 Apr 2026
Prior to starting the job, Shefit was very responsive to my emails and WhatsApp messages and was very easy to communicate with. I left Shefit detailed instructions of where to position the walls we wanted constructing for our small extension as I was not going to be there when he arrived. I returned later that afternoon to find the job well under way - he had even sent me a short video of the work in progress - yo find everything had been done as per my instructions. The team worked all day and finished the job in about 8 hours - hardly stopping for a break it seems and refusing any attempt by my wife to ply them with coffee and tea. They left the site clean and tidy were incredibly polite and respectful - one of them even asking if they could use the toilet, which of course they could! I would recommend Shefit and his team wholeheartedly. The price was reasonable and the job was done quickly and cleanly.
