Pressure washing in Port Washington

Port Washington is a North Shore Nassau waterfront peninsula — and one of the most demanding environments we clean in. The harbor-facing elevations on Shore Road, Harbor Road, and the Sands Point adjacent streets accumulate salt oxidation, osprey-nest debris, and green algae growth 30-50% faster than comparable Nassau homes inland. Our Port Washington work is heavily weighted toward roof cleaning (about 60% of jobs) because the salt-and-shade combination on north-facing roofs grows gloeocapsa magma aggressively — shingles here can streak visibly within 18 months of a prior cleaning. House washing requires a higher-dilution chlorine mix than inland vinyl homes because salt-air chalk on north and west siding needs a longer dwell time to release. Stucco is common in Port Washington's older stock and requires a low-pressure, extended-dwell protocol to avoid driving solution into cracks. Wood decks on bay-facing properties need oxalic acid brightener plus a UV-inhibiting sealer to survive the marine environment between washes.
