Light fixture installation in Richmond Hill is often part of an LED changeover. The executive houses in Bayview Hill and Westbrook were built with halogen pot lights, glass pendants and dimmers from the incandescent era, and swapping the bulbs alone is what makes them flicker.
I change fixtures and trims and I change the dimmer to match, so the two work together. Chandeliers, vanity lights, kitchen pendants and ceiling fans all get the same treatment on the circuits you already have.
