Kitchen Fitting- 5 Oct 2025
I couldn’t be happier with the work Mariusz has done! The kitchen fitting was done so neatly and with amazing attention to detail, all the plumbing, gas and electrics were completed perfectly too. He kept to time and finished everything as promised, which I really appreciated. Mariusz is very tidy and takes real pride in his work. He also helped with adding shelves and fixing panelling to the bedroom and brough my vision to life, it turned out exactly how I wanted! He’s easy to work with, always willing to help, and made the whole process so smooth and stress-free. I’d definitely recommend him to anyone looking for someone reliable, skilled and genuinely great to work with.

Extensions- 6 Sep 2018
Simon & his team have done a rear extension & loft conversion for us. The work has been carried out to a high standard and was completed ahead of schedule. Simon has been professional throughout and we had a very positive working relationship. He gave us good advice & suggestions throughout the project which improved on the plans from our architect. He also listened to our ideas and was always willing to add in extra bespoke details, for example, a bar in our kitchen based off a Pinterest picture. His team are all polite & hard working. Overall a very positive experience!

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.

What experience do you have with similar extensions in Norbury?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Norbury extension builder’s ability to deliver a result that meets your expectations.
