Established 2011
Local roots. Standards we keep pushing higher.
SMC began in Cardiff with a simple promise: give customers honest advice, take pride in the work and treat every home with care.
SMC has grown from one van into a trusted local team, but the things that matter have stayed the same: honest advice, tidy workmanship and a job done properly.
Every job carrying the SMC name matters—whether it is a small repair or a complete home project.
