JNJ Building Services Ltd

We had our loft converted by JNJ Building Services Ltd at our home in Kew, and the entire experience exceeded our expectations. The project involved significant structural work, but Jamie and his team approached it with impressive professionalism, skill, and care. Communication was consistent and clear throughout, timelines were honoured, and the quality of workmanship was exceptional. The team was always punctual, respectful of our home, and left the site tidy each day — something we appreciated. What stood out was the aftercare. Even long after the project was completed, Jamie was quick to respond and happy to come back to handle any small repairs or touch-ups without hesitation. That level of commitment and integrity is rare. The finished loft space is exactly what we hoped for — beautifully done and a real asset to our property. It’s rare to find a company that combines technical expertise with genuine customer care, but Jamie Jenkins Development delivers on both fronts. We would highly recommend them to anyone considering home improvement work.

I booked JNJ to knock down an internal wall to open up my kitchen and dining room into one space. They also had to move some electrics and plumbing, lay a new floor, create a new doorway and do some plasterwork. The schedule and budget were revised downwards in week 1 when we realized it wasn't a supporting wall. After that, the work was carried out to the new timescale and budget. JNJ stood out because they brought in a structural engineer to assess the project before I agreed to go ahead. This gave me a lot of confidence that they were taking it seriously. They also seemed very knowledgeable and professional. They took time to explain everything and had all the right accreditations. All the different tradesmen who came on site were friendly, polite and worked to a high standard. The only thing that could have been better was a slight lack of communication towards the end of the project about when it would be completely finished, but that was resolved with no problems.

After considering many building contractors we decided to employ JNJ building services due to their reputation in the West London area. However, their appointment was also decided due to the accreditation's they have been given from various professional bodies and previous high-quality work they have completed in the area. JNJ Building services from initiation to completion always maintained a very high standard, they were punctual, adhered to H&S compliance (full 5 point PPE) at all times and always gave an excellent appearance (well dressed, clean and no tracksuits) and always left the site tidy and safe, their housekeeping was excellent. Plus, they educated our children with the dangers of construction. What was also impressive was their honesty from start to finish; they always communicated their progress via reports (these can be provided if needed) and daily site meetings, usually at the end of the day. Also, critically they were always very honest if problems had been encountered during the build, they were always quickly rectified. Very importantly they achieved the estimated cost, the quality was 10 / 10 and they completed exactly within their time frame. I can say with absolute certainty I would recommend JNJ Building Services to anyone that is looking to carryout building work in the London / South East region as their complete package was excellent and we are 100% happy with the single story extension that they completed.

JNJ Building provided me with an excellent service, throughout the duration of the refurbishment of my kitchen and bathroom. They provided a professional and well experienced team, who completed the project to a high standard and made sure that all pre-existing building work was removed and re-fitted correctly. They provided me with lots of updates and reassurance throughout the project, which provided me with a lot of comfort in knowing that my home was in safe hands.

We would highly recommend Jamie and the team at JNJ Building Services. JNJ was engaged after we had terminated our engagement with another contractor following their unsatisfactory performance at the planning stage. To begin, we were very impressed with the introduction session which went through a lot of the details that we may not have thought of, the quotation provided was also transparent and set out in detail the cost for each area of work. What we found most impressive was that unlike many other contractors we came across, the JNJ team had a lot of helpful suggestions on reducing unnecessary work and materials. We would also like to commend on their daily updates and responsiveness to our questions, all of which was done via a WhatsApp group. We were promptly reminded by Jamie to order the items when required and this helped reduced the lag time to get materials and deliveries and allowed the project to be progressed smoothly without having to wait long periods due to uncoordinated schedules which we suffered on our previous building project. Overall they have delivered a luxury high end finish and we can now enjoy our new home. Thanks Jamie and the team!

We had started our kitchen renovation just before lockdown and JNJ were extremely helpful at such a stressful time. They were able to make sure that we were left with a functioning kitchen when work had to pause, working very quickly to get everything in and being flexible about the original plan. The work was high quality and the team were very good about cleaning up after themselves. The can-do attitude of the team was one thing that attracted us to JNJ over the other quotes we had received, and this was borne out in the way they worked and solved challenges that came up.

JNJ Building services Ltd are outstanding! They constructed our luxury bathroom. From the second I met Jamie I felt we had found the right person and company. I was so surprised how transparent he was. JNJ gave us a detailed quotation with different options which was very helpful. We were informed of the progress during the development several times, and despite some unexpected complications, works had been finished in the agreed time frame. They really do go the extra mile to deliver a high-end finish. We are more than happy with the quality of the works and professionalism. We will be using JNJ again and again.

I was surprised at the level of openness and honesty that Jamie presented to me at just the quotation stage. Everything was laid out on the table to me in a sincere and honest manner and a huge amount of trust arose from that it is rare to find that with builders in my opinion. professional and presentation was spot on and again I was surprised at the amount of consideration that went into the setup of the site for a residential project. It gave the whole project a sense of safety, care and cleanliness and really put my mind at ease. I felt comfortable and relieved that my property was left in good, professional hands and it made the whole process so much smoother. Just having my fears and the stress of a project like that laid to rest was worth choosing JNJ! A couple of unexpected issues arose during the project and the initial quotation had to be amended a little which, as you can image isn’t the greatest feeling but the openness and clear willingness to explain and make clear to me in layman’s terms what those issues were and how they could not have been identified by either parties prior to works taking place made the whole thing much more digestible. Excellent communication and integrity! Timeline of the project was amended, and I was made aware of progress every step of the way. I really felt a part of the process the whole way through. Finish was far beyond what I expected, and I am so happy with my property and the whole process as a whole. Thank you Jamie

First Impressions & helpfulness - Jamie and the team were all very approachable and made sure to point out things you may not have thought of when planning your project. Community - whilst the works were ongoing, I know Jamie helped our neighbour, an elderly gent, move some heavy items into his house which he did not have to do but was very much appreciated by our neighbour. Professionalism - the team were always professional but personable too. Appearance - the site was always immaculate, and they left our home clean and tidy after each day's work which was appreciated as we had to live there whilst it was ongoing. Knowledge - Jamie and the team around him had clearly a good level of knowledge and helped us consider things we had not thought of ourselves which made the final product much better than it would have been. Work Quality - the final outcome was fantastic, and we are extremely happy with the kitchen and living area. Communication - it was always easy. Whether face to face, telephone, WhatsApp, or email. Much appreciated as it is a stressful time! Safety - all safety precautions were taken, the site always kept clean and free of hazards. After Care - the retention payment is a fantastic idea as any "snags" can be and were dealt with by Jamie or his team in a timely manner. Deadline and budget - deadlines were met and budget was stuck to down to the penny. Extra jobs were even done that were not accounted for in the original agreed budget.

I cannot recommend JNJ more highly; their professionalism and work quality were certainly the highest standard I have experienced from builders based in London. They were a pleasure to work with throughout the duration of our project and I never lost confidence in their ability to deliver. As with most building works, there were a couple of sticking points, but JNJ were brilliant at resolving these issues and making sure everything ran smoothly. Invoices were sent on time and all deadlines were met. A great bunch of workers who we would certainly use again. We even missed them once they left!
