What to do this week

Pick one change from this article and do it before Friday. Small improvements stack; perfection next month pays nothing today.

1. Write down your current process — quotes, follow-ups, or how customers find you
2. Fix the weakest step (even if it's just a voicemail greeting)
3. Tell one happy customer they can mention you online if they were pleased
4. Review your website on your phone — would you hire you?

Worth remembering

None of this replaces good workmanship. But in 2026, the trades winning steady work in Cardiff and everywhere else tend to combine solid on-site skill with a business that looks organised online. You don't need to be flashy — just clear, reachable, and professional.
