Guilderland properties tend to sit on big wooded lots, which means long driveways — often stretching well back from Western Avenue or tucked into Altamont's hillier terrain. Those long runs of concrete and asphalt collect sap and leaf tannin stains from overhanging trees, plus tire marks and algae along the shaded edges, all baked in by seasons of Capital Region sun and salt.
Winter is the biggest culprit. Plows push salt-laden slush across driveways all season, and water works its way into hairline cracks before freezing and expanding. By spring, a lot of Guilderland driveways look blotchy and gray, with dark patches near the garage and lighter halos where a homeowner tried scrubbing with a garden hose.
We clean Guilderland concrete and asphalt with a commercial rotary surface cleaner — the same equipment used on shopping plaza lots — for even coverage with no wand-mark stripes. After cleaning, we recommend sealing, which is especially important here given how many long driveways sit exposed to sap, salt, and shade year-round.
