JNJ Building services have restored my faith in building firms. We got exactly what we paid for with a high degree of commitment and professionalism. Jamie is 100% committed to meeting client expectations and has a degree of pride in the finish that is rarely seen. Thanks, so much Jamie and team!

Jamie and his team are very professional and considerate and produce good quality work in good time. The estimates given are always detailed and fairly accurate so there are very rarely any extra hidden charges suddenly appearing. Jamie always keeps you informed and always makes himself available for any questions. The work is always completed on time and the place is always left clean and tidy. The after care is also available and much appreciated! I would recommend JNJ Building for any work required.

We were recommended JNJ Building Service Ltd from a close friend who was a previous client of JNJ. From the outset of the interaction we were impressed and thus chose JNJ from a tender list of 6. Jamie took considerable time walking us through all the documents of JNJ including their code of conduct, complaints procedures, quality assurance processes, communications procedures, and the contracts which they intended to use with us. As with the entire engagement, we were extremely comfortable and happy with JNJ, mostly due to the customer service and attention we were paid by the site manager and Jamie. This type of professionalism was unexpected, especially due to the stereotypes which the building professionals have. Jamie and the JNJ team are truly correcting that stereotype. The quality of the work is fantastic, and we were delighted with the result, well above what we envisaged. JNJ has truly helped create our luxury dream home and place of relaxation. We constantly recommend him everyone who comments on how beautiful our home is.

Specialist brickwork and bay window repair

We chose JNJ Building Services Ltd in a competitive tender to repair damage done to our bay windows. The work required the erection of new brick piers and the replacement of broken wooden shutters & windows which were operated by sash cords and weights. JNJ prepared a clear description, budget, and time plan for the work which they kept to. The quality of the brick work was excellent, and they took care to use the existing bricks where possible. The shutters were successfully replaced with new cords and weights. Overall, JNJ did a first-class job and were friendly and reliable throughout the work. They had a professional approach and worked well with the separate firm who replaced the windows and who had been recommended through JNJ.

Jamie & his teams completed a porch extension for my mother-in-law last year, to include a new downstairs toilet that she needed. They provided a comprehensive quote, committed to a convenient start date and agreed a sensible payment programme to protect both parties. There were a number of challenges on the job that they successsfully overcame, but meant that it did over run slightly. However, they did undertake additional works that my mother-in-law requested, at a cost that reflected that they were already on site. The standard of work was high and team members friendly, with my mother-in-law comfortable to have them in her home. Finishing some minor snagging at the end took a little time, but understandable as they had moved on to another job. All completed successfully on budget & a good job done.

I have had 3 different jobs done. My complete refit of my bathroom. Partial refit of my kitchen. Also patio done in garden. Jamie was very friendly and helpful. He gave a proper quote and stuck to it. He was never phased by any issues and did a very good job on all 3 jobs. He was very tidy and always came back if any issues after job completion. When the decorator he got to finish the painting let me down, he immediately got someone else at no extra cost to fix the issues. I would highly recommend this company.

JNJ Building fixed an issue with the guttering and our roof, which was causing water to seep down an exterior wall resulting in damp forming in the wall. They did an excellent job, taking care not to damage the lawn and left the work area clean and tidy.

Jamie and his team re-did our garden to an extremely high standard. Removed decking and laid a patio. Built a beautiful flower bed which runs around the edge of the garden. Installed lights as well. The team also built a bespoke walk-in wardrobe which is gorgeous. The carpentry was to an exceptional standard. They also removed existing shelves and build bespoke shelving.

We had a loft conversion, side unfil (side return) & a 3 meter extension out of the back of our house. We have used JNJ builders once before and had a very positive experience with them, so didn't hesitate to use them again on our building work. Once again we had a very good overall experience with them. The quality of work and finish was very good & they came in on budget. I am always able to call on them if there are any teething problems and they do their best to come straight away to fix any problems, that are inevitable in all building projects. We would definitely use them again in the future.
