Extensions- 24 Jun 2017
We had a large piece of work done by Johan and his team. It was a 4m single storey rear extension with new kitchen installation, converting the old kitchen into a downstairs bathroom and utility room, plus other bits and bobs like new boiler, rear patio. We got quotes from a few builders, Home Renovations weren't the cheapest, they were actually towards the higher end. But we went and saw their previous work and spoke to some of their other clients. The work was done to a high quality and the clients seemed to be happy so we decided to go with them. Johan's team are very hard working, professional and polite. Pawel and his team of builders, bricklayers, plumbers, electricians, etc. would turn up before 8am and finish at 6pm working solidly throughout the day. There is Magda as the project manager who keeps you in the loop, and answers any of your questions (which we had many). There is Michaela on the finance side who keeps you up to date with the budget. Our budget went over by 5% with "variations" (extra work or materials) but it was always communicated why and the work wasn't done without our approval. Pawel would give his recommendations but the final word would always be ours. But these things can add up. Overall we were very happy with the build, it was done to a very high standard. They also finished it before time. They said it would take 12 weeks in fact they finished it in 10 weeks which was amazing as you would normally expect these things to go over.

Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

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.

Sean did a full refurbishment on our house. He is the most organised and customer friendly builder I have ever used. From start to finish there was a plan of action and then a great group of qualified tradesman to execute. Like every refurbishment, we asked for changes and he always made us feel like the extras were no problem. I have no hesitation in recommending CG Carpentry. They are now our go to builders and in our next move he will be the first person I call.
