Central Ohio's four distinct seasons each affect your home's exterior differently — and they shape when exterior cleaning works best. This guide walks through the year so you can plan house soft washing, roof cleaning, and driveway washing for the best results.
The short answer: for most homes in the Columbus area, late spring through early fall (about April to October) is the sweet spot. Temperatures stay above freezing, cleaning solutions perform as designed, and surfaces dry properly. But each season has its own advantages.
Spring (April–May): clear out winter
Spring is one of the busiest and best times to wash. Winter leaves behind road-salt film, grime, and the first flush of algae, and Central Ohio's heavy spring pollen coats siding, decks, and concrete in yellow-green dust. A spring house soft washing resets your home's appearance for the year and removes pollen that can otherwise stain.
Summer (June–August): peak growing season
Ohio's humid, warm summers are prime conditions for algae, mold, and mildew — especially on shaded, north-facing surfaces and roofs. Summer is an excellent time for roof soft washing to remove black algae streaks, and for tackling growth on siding and decks. Long daylight hours mean surfaces dry quickly. The only caution is scheduling around stretches of rain.
Fall (September–October): the smart pre-winter wash
Fall may be the most underrated time to wash. Removing a summer's worth of algae, mildew, and grime before winter means organic growth isn't trapped against your surfaces under snow and ice for months. A fall driveway and concrete cleaning also clears slippery growth before the freeze-thaw season makes walkways hazardous. Decks and paver patios deserve the same treatment on the way into winter — our deck and patio cleaning lifts the algae film that makes boards slick as soon as the frost arrives.
Winter (November–March): wait for a warm spell
Central Ohio winters bring freezing temperatures that cause rinse water to ice over on surfaces and walkways, and cold reduces how effectively soft wash chemicals break down growth. Washing is possible on milder, above-freezing days, but for most homeowners it's worth waiting for spring. Winter is a good time to plan and book ahead so you're first in line when the weather breaks.
What matters more than the calendar
- Temperature — above freezing (ideally 45°F+) for chemicals to work and surfaces to dry.
- Dry weather window — surfaces should have time to dry; soft wash solutions need dwell time without heavy rain washing them off too soon.
- How much growth is present — heavy algae or mildew shouldn't wait. If your siding or roof is visibly streaked, the best time is soon, regardless of season.
- Your goals — washing before a sale, a party, or the holidays is worth scheduling around even if it's not the textbook season.
How often, not just when
Timing within the year matters less than keeping a consistent schedule. Most Central Ohio homes do well with cleaning every 1–2 years; shaded or wooded lots may need it annually.
