First contact onwards was extremely approachable, professional and reassuring. Kate assessed the practicalities and provided a competitive quote. She was most accommodating when we had to re-arrange dates.

Worked with JSS over the past 18 months on various projects across HS2, work is always completed to the highest standard and the team is always willing to help and provide value adding solutions. They have an excellent direct workforce who all share the same care and attention to quality, health and safety as James and George. Can not recommend JSS highly enough, they are a great asset to have in our supply chain.

There's nothing these guys can't do!! I've worked with Jones site services & Installations for a couple of years now and they always exceed expectations. From the down right dirty task of clearing sludge out of a recycled water tank to barrier installation and more recently a complete aggregate storage solution in the form of a 300 tonne capacity bay built to last. They offer platinum level service and results are always second to none.
