Install Slider Dimmer Switch

I need my current wall-mounted dimmer switch swapped for a new slider-style unit. The existing wiring is standard single-pole and the switch controls one indoor light circuit. I have not purchased the replacement hardware yet, so I’m happy to follow your recommendation on a reliable brand; just make sure it is a smooth linear slider rather than a rotary or touch panel.

The job involves:
• Safely isolating power at the breaker, removing the old dimmer, and installing the new slider dimmer.
• Verifying that the slider delivers a full, flicker-free range of brightness once re-energised.
• Finishing with a clean wall plate and no visible gaps or scratches.

Please bring the necessary tools, voltage tester, and any minor consumables (wire nuts, screws, tape). Ideally you are a licensed electrician or can show relevant experience so I stay compliant with local electrical codes. Let me know your availability and how long you expect the swap to take.
