Kitchen Fitting- 8 Nov 2017
After a cowboy builder failed to install our kitchen Tomaz came to the rescue. He gave us a very fair price as he knew we had lost out money already having to replace broken or damaged parts of the kitchen. He communicates very well through the build and always called me on FaceTime to show me things he was doing in the kitchen and to ask for my preferences. If anyone needs a kitchen fitter with minimal hassle use Tomaz. The job was completed in a week, which included tiling . He fitted a howdens kitchen from scratch And it looks very tidy. Thanks Tomaz, next job loft extension !

Extensions- 27 Jun 2018
Rapid Response completed a single storey kitchen and bathroom extension for us, as well as refurbishing our existing bathroom and doing a complete rewiring for the whole house. Sheraz and his team were very friendly and a real pleasure to deal with, and their attention to detail and customer service was excellent throughout the whole process. They talked us through each stage step by step, giving us a range of options as well as providing advice on what would work well. Even at the end of the project they asked if we had any little tweaks or finishing touches and wanted to make sure we were happy with everything, which was incredibly helpful. The prices were very reasonable and we are very pleased with the final finished work. We would highly recommend Rapid Response and will definitely be using them again in future. Many thanks!

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Extensions- 25 Jul 2023
Vini and his amazing team became part of our family for the months they were working on our house! Attention to detail and great communication was a top priority for me before starting our large scale renovation, and they delivered above and beyond on every front. Vini’s team helped transform my vision into a reality - they weren’t thrown or intimidated by any of my crazy/creative ideas, and were equally ready to advise and bring constructive ideas of their own to the table, based on their years of experience. We would highly recommend Olaj Brothers as trustworthy, professional and highly skilled tradesmen.

Extensions- 13 Feb 2025
Shami and his team had been fantastic from start to finish! Before hiring his team he showed me around a house his team built, which was amazing to see. His communication was excellent throughout the progress of my renovation and very reassuring. Even as I had made changes to the build, he was very helpful in planning and adjusting to my needs. His team had built a single floor rear extension, including a new kitchen, bathroom suite, full electric rewire and plumbing from scratch. Also, comparing his team with six other builders, he had one of the most competitive quotes for the build. Post finishing the job, any issues I had were resolved immediately putting me at ease! I would definitely hire Shami and his team for any future jobs.
