Reviews

Seaspray Fifteen

I have been working with CBS for over a decade on small and medium sized projects for BIMM University. They have always been consistent and work to a high standard. They have often helped me get out of problematic situations with last minute turnarounds.

Lee Bryant

I have used CBS on numerous occasions now for fit-out, refurbishment, construction and demolition works for large commercial spaces in Horsham and Burgess Hill and can't recommend them highly enough. They come with a wealth of experience and as well as helping to facilitate a pleasant and stress-free experience from planning, through execution, to completion, are an invaluable source of consultation. During all projects, they have always gone the extra mile to ensure the project is carried out in alignment with organisational requirements, ensuring all internal processes are followed at each stage. Additionally, they have an excellent network of sub-contractors to utilise, who have helped with many of our more specialist requirements. They also always maintain excellent communication, responding to requests and queries promptly, and have been very thorough ensuring statutory compliance is achieved at all times. Above all, all members of the CBS team are very personable and a pleasure to work with.

Amy Feist

We’re really grateful to Steve and the team at CBS for all the work they have completed at Havelock Community Centre. They’ve installed new LED lighting throughout the building, fixed some damaged flooring, and we’re now working with them on bigger projects planned for the end of summer, including new astro turf, new flooring, and other jobs. They’re friendly, professional, and always quick to respond with helpful ideas and solutions. The work is always finished to a high standard, and they’re a team we completely trust. Highly recommend!
