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.
