Lewes-Based Crew Details How Often Sussex County Homes Need Service After Salt Air and Nor’easters

Lewes, United States - July 6, 2026 / Pressure Washing Marketing Pros /

East Coast Window Cleaning has published a Delaware-specific guide explaining how often homeowners should clean their windows, with separate schedules for coastal Sussex County properties and inland homes in Kent and New Castle counties. The state’s mix of 45 inches of annual rain, hot humid summers, and a coastline that deposits salt film on glass means the standard “twice a year” rule fits some homes and falls short for others. The full guide, How Often Should You Clean Your Windows in Delaware?, maps cleaning frequency to property location and surroundings.

Why Delaware Properties Don’t Fit a Single Cleaning Schedule

Window cleaning frequency in Delaware varies more by zip code than most homeowners realize. According to the Delaware Climate Office at the University of Delaware, the state sits in a transition zone between humid subtropical and humid continental climates, gets roughly 45 inches of rain per year, and catches nor’easters that drag salt spray well inland during spring storms. Coastal homes in Lewes, Rehoboth Beach, Bethany Beach, and Fenwick Island collect a salt film that hardens on glass and corrodes window frames, while inland properties in Wilmington, Dover, and Newark deal mainly with spring pollen and hard water from sprinkler overspray. The U.S. Department of Energy notes that heat gain and loss through windows is a major source of home energy waste, and film buildup blocks the solar heat gain that warms rooms in winter. Those conditions explain why a single statewide schedule does not fit every property.

What the Guide Recommends for Each Type of Property

The guide breaks the schedule down by property type and location. Most inland Delaware homes need two professional cleanings a year, one in spring after tree pollen peaks in late April or early May, and one in fall before winter sets in around late September to mid-October. Coastal homes in Sussex County beach communities typically need three to four cleanings a year because of salt air buildup, and storefronts and restaurants along the Route 1 corridor and downtown Wilmington, Lewes, and Rehoboth run on monthly or bi-weekly service to keep glass clear for foot traffic. Office buildings and apartment complexes generally fall on a quarterly schedule.

What East Coast Window Cleaning Says Delaware Homeowners Should Know

The new guide builds on more than two decades of work cleaning windows across Sussex, Kent, and New Castle counties. “Coastal homes and inland homes are not the same job, and giving everyone the same schedule does not match what we see on properties in Delaware. We built this guide to give homeowners a straight answer based on where they live, what’s around them, and what kind of weather their glass takes through the year. After more than 25 years cleaning windows in Sussex County, we know a Lewes home and a Wilmington home need different attention,” said Pete Norwood, Owner, East Coast Window Cleaning.
