We hired JNJ Building Services Ltd for a complicated step-down foundation extension and a full renovation of our home. The project was completed on time and within our agreed budget, they even managed to get us back in before Christmas, which was amazing! Their technical ability and quality of workmanship were outstanding throughout. The team worked efficiently, maintained excellent communication, and kept the exterior areas exceptionally clean and tidy. They were also fantastic with our neighbours, which made the whole process stress-free. We’re super impressed and couldn’t recommend JNJ Building Services Ltd more highly, truly a five-star service from start to finish. Date works completed: 23/12/24
This is our third project with the wonderful team at JNJ Building Services Ltd. This time, they renovated our bathroom, and once again, the service, communication, and attention to detail were fantastic. The finish looks incredible, and we’re absolutely delighted with our new bathroom. The project ran a little over schedule, but JNJ kept us fully updated throughout, and we’re still super happy with the final outcome. When an issue arose with the supplier’s shower tray after tiling, JNJ worked hard to fit in the extra work needed around their other projects, and resolved it professionally. It’s always a pleasure working with the JNJ team: they’re professional, reliable, and consistently deliver excellent quality. We wouldn’t use anyone else!
Jamie Jenkins and his company did extensive building work to our home, knocking down walls and installing RSJs in order to create a new spacious downstairs kitchen-diner with new fitted units, downstairs loo and bi-fold doors. Jamie and Nigel were great in both the design and build, creating a clean modern solution at the back of the house. The work was done to time and to the original estimate. Most importantly the team were friendly and trustworthy. Highly recommended.
I helped my mum with a new ground-floor kitchen renovation and bathroom project. We first noticed JNJ Building Services Ltd from their hoarding and family advertising near us, and from the very first meeting, they were fantastic, professional, friendly, and incredibly helpful. We hired them on the spot. The workmanship was stunning, with excellent quality and great attention to detail. The kitchen looks amazing, and my mum is absolutely over the moon. We were so impressed that we went straight ahead and had them complete the bathroom too, same brilliant experience all over again! We couldn’t recommend JNJ Building Services Ltd more highly.
JNJ truly saved our home! We had an absolute disaster with many previous builders, where the project had become a complete catastrophe, and we’d lost all hope. Then one day, we walked past one of JNJ Building Services Ltd’s sites and saw their family-branded hoarding. We decided to reach out, and it was the best decision we ever made. From the first meeting, Jamie and the JNJ team were incredibly professional. They clearly explained the Health & Safety requirements, the WHICH? Trusted Trader standards, and the step-by-step process they follow. We immediately felt in safe hands and a team that worked well together. For the first time in a long time my wife and I felt hope. A structural engineer was brought in to assess the previous work, and we discovered 15 structural errors from previous cowboys. JNJ took full control, resolved every issue, and restored our confidence in the project. They handled difficult situations, including very unhappy neighbours who had endured, with patience and professionalism throughout. The quality of the finished home is exceptional. They turned a nightmare into a success story, and we are genuinely grateful. We cannot recommend JNJ Building Services Ltd highly enough, they truly saved our home. Date works completed: 04/07/24
A full and complicated project carried out by JNJ Building Services Ltd, and we couldn’t be happier with the result. The works were extensive and completed in several phases, involving road closures, hand digging, water connections, a full rewire and new plumbing throughout, plus a large amount of complex structural work. Despite the challenges, the JNJ team managed everything with professionalism, great communication, and excellent coordination between trades. The project stayed on schedule and within budget, and any unexpected issues were dealt with quickly and efficiently. The attention to detail, site organisation, and overall finish are exceptional. We now have an incredible home, and we can’t thank Jamie and the JNJ team enough for their hard work, expertise, and support from start to finish. Highly recommended!
JNJ Building Services recently sorted out my garden in Shepherd’s Bush, and I’m so pleased with the result. They completely transformed the space — it’s now clean, stylish, and ready to enjoy. The team worked quickly, kept everything tidy, and delivered exactly what I asked for. I was so impressed, I asked them to take a look at some complicated brickwork at my parents’ house. They handled it brilliantly — careful, precise work and no fuss. Reliable, skilled, and genuinely easy to deal with — I’d definitely recommend them.
We hired JNJ Building Services Ltd for a loft conversion and full refurbishment of our home in Kensal Rise, and the results have completely exceeded our expectations. From start to finish, the team was professional, efficient, and clearly passionate about what they do. The loft has been transformed into a beautiful new bedroom with an en-suite, and the rest of the house has had a full makeover — new kitchen, bathrooms, flooring, electrics, and plastering. The attention to detail and quality of finish is genuinely top-tier. What really stood out was the clear communication and seamless project management. We always felt in the loop, and any unexpected issues were dealt with quickly and transparently. Even after the project was completed, JNJ were happy to return for a couple of small snagging bits — no hassle at all. If you're considering a renovation in West London, we couldn’t recommend JNJ Building Services Ltd more highly. Reliable, skilled, and a team that truly takes pride in their work.

The transformation is incredible, the space feels brighter, more modern, and so much more functional. The team were professional, tidy, and easy to work with from start to finish. They listened to what we wanted, offered great suggestions, and delivered everything to a really high standard. It’s rare to find a company that combines great workmanship with such clear communication, but JNJ nailed it. Highly recommend!
We had our loft converted by JNJ Building Services Ltd in our home in Kew, and we couldn’t be happier with the results. This was a complex project with a lot of structural work involved, but Jamie and the team handled everything with total professionalism and attention to detail. From day one, communication was excellent, timelines were clear, and the workmanship was top quality. The crew was respectful, tidy, and genuinely a pleasure to have around. The space has been completely transformed — it’s added so much value and functionality to our home. Highly recommend Jamie and his team if you're looking for a trustworthy, skilled company that cares about the work they do.
We hired JNJ Building Services Ltd to build a ground floor extension on our home in Chiswick, and we’re absolutely thrilled with the outcome. From the very beginning, Jamie and his team were professional, reliable, and incredibly easy to work with. The project involved structural work, opening up the back of the house, and creating a new kitchen-dining space, and the attention to detail was second to none. Everything was completed to a high standard, on time and on budget, with no corners cut. What really impressed us was the team’s attitude: polite, tidy, and respectful throughout the build. Jamie was always on hand to answer questions, offer advice, and keep things moving smoothly. Even after the project finished, he checked in and was happy to pop back for any minor tweaks. The extension has completely transformed our home; it’s bright, spacious, and exactly what we hoped for. We wouldn’t hesitate to recommend Jamie Jenkins Development to anyone looking for a quality builder in West London.
We used JNJ Building Services Ltd for both a loft conversion and a ground floor extension at our home in Shepherd’s Bush, and we couldn’t be more impressed. From the initial consultation through to the final touches, the team was professional, proactive, and a genuine pleasure to work with. This was a major project involving structural alterations and a complete transformation of our living space. Jamie’s eye for detail and commitment to quality really stood out. The new loft bedroom and en-suite are beautifully finished, and the rear extension has given us a bright, open-plan kitchen and living area that we absolutely love. What sets this team apart is their reliability and ongoing support. They stuck to the schedule, communicated clearly at every stage, and even came back well after the project was done to make a couple of minor adjustments — no fuss at all. If you're looking for a trustworthy, skilled, and considerate builder in West London, we’d wholeheartedly recommend JNJ Building Services Ltd.
