Most gutter guards sold in Clifton Park fail the same way. Hardware-store screens sag and trap debris on top, and micro-mesh eventually blinds over with shingle grit and pollen until water sheets straight over the front.
Those patios are now 15–25 years old: the original joint sand is gone, moss has moved into the shaded backyards near Vischer Ferry, and pavers rock underfoot at the edges.
We install RainDrop® Pro Gutter Guard: a UV-stabilized polypropylene system that retrofits 5" and 6" gutters, handles high-volume roof valleys without overshoot, and sheds ice instead of holding it. Every install starts with a full cleanout and ends with a water flow test.
