Testimonials

Principal Engineer, Swansea Council

“Kaymac have always provided an excellent, economic, efficient and effective service. They have delivered quality workmanship, safely, to programme and within available budget. They were easy to work with on site and the final account was settled amicably, with no disputes. I will look forward to working with them again.”

Crickhowell & Llangynidr Bridge Repairs

I’d like to say thanks for all your help in competing the remedial works to Crickhowell and Llangynidr bridges ready for another winter. Dean and his team worked well, were professional at all times and really easy to work with. CADW are happy with the repairs and we have even had a few locals stop and say how great the repairs look.

Kaymac are always the go-to solution for my diving requirements.

Cobb Valley Viaduct

Kaymac provided an excellent and reliable service throughout the whole project. The Communication between everyone on site was continuous which ensured clarity with all staff members. The Kaymac team had a great understanding of the project as a whole particularly with the safety and site-specific tasks that were required, and as a result, the project was very successful. A big thank you to Jeff and the team for their impressive work on this high risk project, I will look forward to working with you in the future on other projects hopefully very soon.
