Bathroom Fitting- 26 Aug 2026
We found Vadet to be a very thorough, hard-working, precise and reasonably priced choice. Vasile himself is a good communicator and throughout the job, he pointed out different options as they cropped up, and the costs they'd incur. I know this is to be expected, but he did it well.

Plastering- 8 Jun 2026
We were thoroughly pleased with Bathroom Renovation, Bahram and the services provided. We required stud walls throughout our apartment, ceiling replacement and ducting/pipework concealing. I can only say that Bahram and his communications have been a breath of fresh air. The team are efficient, friendly and get the job done - most importantly Bahram takes pride in the work his team complete. Our job was relatively urgent and Bahram offered what I feel was a fair price, remained communicative and had his team readily available to get the job completed within the timeframe. Most importantly, as with it seems all building works, jobs can grow slightly, but Bahram’s considered approach and advice was invaluable. We increased the scope of our works mid-job, and are really pleased with the results. Fair pricing, someone who has pride in their work, and a job well done.

Extensions- 17 Apr 2019
My extention was left incomplete by a incompetent builder, I had plenty builders coming around for quotes until I decided to go with Peter & Chris after receiving their detailed quote with everything explained in blank and white. I am extremely happy with my choice, as they did a great job finishing the project on time and most importantly great finishes. Peter has an amazing interior design taste, I would definitely recommend picking his brains, Chris on the other hand is very experienced and knowledgeable in building, both work very well together as well as his labourers are very respectful and hardworking. I recommend Peter & Chris to anyone who wants a stress free project. An above and beyond service !

Extensions- 14 Jul 2021
Juro and his team completed a total refurbishment of our house that included removing all internal walls, along with a double story side extension, a huge job involving lots of steels, re-roofing, new construction, new bathrooms and kitchen, new windows and rendering along with all the plumbing and electrical work and decoration. They did the most incredible job, working efficiently, adapting to any problems that came along and working really hard to create the best finish possible at the budget we had. Despite the pandemic arriving just after the demolition stage, they didn’t miss a day on site, and worked tirelessly to get materials to keep the project moving. Incredibly they still managed to finish the project on schedule and to a standard that was exceptional. Juro is honest and upfront, didn’t ever add costs or ‘unforeseeables’ and was an absolute joy to work with. He also stuck to a very clear payment schedule that was easy to follow and always meant we only paid when we were absolutely 100% happy. My only reservation in writing this review is that I would like to selfishly hang on to him and keep his schedule clear for future jobs with family and friends!

Lerida was excellent- would highly recommend. Met with us, understood our needs, and produced a good set of options and designs. Our preferred option was then tweaked further with great attention to detail shown. We are now looking forward to working with them on the build of the project.

Extensions- 9 Oct 2022
We engaged NB Building Services to build an extension (new garage and room at the rear) and extensively refurbish/remodel a bungalow. I met a number of builders/building contractors but I felt immediately comfortable with Nick right from the start. It was the first time we were ever starting such a project and we wanted to follow our instinct and go with someone we could be comfortable with over the duration of the project. Right from the start Nick came across as someone who is genuine and who looks to understand your requirements. Also, as my project had a few uncertainties that could affect the scope of the project I was looking for some flexibility and I felt that Nick and his team could provide that. Nick and his team (Stefan, Boris and Ilco) work very well together as a cohesive team. Nick provided a day-to-day customer contact while scheduling tasks on the building site and coordinating material deliveries. Every member of the team worked a full day and on occasions where it was important to finish something on the day, they would stay late to finish the job. What impressed me most when the work started is that the entire team is multiskilled – they do everything from bricklaying, timberwork, roofing, plaster/skimming etc. This helped me immensely when there were minor changes or modifications. That meant we didn’t have to wait for the bricklayer or plasterer to return to the site again. Nick also operated the heavy machinery like digger/breaker etc. Once the initial structure was complete the team again impressed me with their attention to detail when they moved inside to lay down plumbing, electrical wires, gas pipes etc. Nick and Stefan took the lead on the fine finishing tasks inside while Boris and Ilco provided important support and completed a lot of other tasks inside and out. It was during this critical phase when communication is most important that I appreciated Nick’s effort to keep us informed. As far as quality of work is concerned while we were happy with everything, I think the tiling work of both Nick and Stefan is outstanding. Our project lasted for about 8 months and while there were lots of discussions on areas of the project that I did not understand and I asked a lot of questions and also changed my mind on some things I don’t remember I we ever even had a minor argument. This I felt was an important win. Nick was also generous with his time and provided help to other trades who came on site e.g. window fitters, garage door installers; boiler installers; electricians etc. Nick and his team returned a few months later to lay down a patio with porcelain tiles for us and also a driveway with block paving. Once again Nick and his team discussed with us in detail what we wanted and provided suggestions based on their experience.

Nanad and his team have been wonderful from day one. We have had them with us a number of weeks doing all the jobs they quoted for and more, they are fast efficient and courteous of the fact we lived in for a lot of the work. Everything has been finished to a great standard and we are thrilled with our house which has been completely transformed. We have already recommended them to friends and will continue to do so and hopefully have them back in future.

Handyman- 12 Oct 2018
The flat was left in a very bad state after the tenants left. Marius was able to undertake all the jobs, from changing carpets, redecorate, repairs and clean up. Also gave good advice as I was not able to attend the site in person so Marius kept me updated with photos. The price was also good. Thank you. Will use these guys again.

Extensions- 22 Dec 2022
Imran is a contractor who is personable and is trying hard, but at the end relies on different teams of builders to carry out the work. His knowledge of building work appears at time limited. In our case, this has often led to poor communication/hand-over, extensive delays and often poor (if not careless) craftsmanship. Very stressful. We now have builders (family business) finalising our project.
