When it comes to maintaining your home’s exterior, timing matters — especially here in Portland, ME, where seasonal changes bring everything from snow and salt to pollen and mildew. So, if you’re wondering whether it’s better to schedule your house washing service in late spring or early summer, you’re not alone. This is one of the most common questions we hear at Viking Power Wash.

Here’s the truth: both late spring and early summer are fantastic times to book your house washing service, but the right choice depends on your specific goals and what your home has been exposed to. Let’s break it down.

1. Why House Washing is Crucial After a Maine Winter

Before we even compare late spring and early summer, let’s talk about why house washing is non-negotiable in our region:

  • Salt, sand, and grime from winter roads cling to siding and can cause damage.
  • Mildew and algae thrive during the wet spring months.
  • Pollen buildup can turn your siding yellow and trigger allergies.
  • Moss and lichen can grow unnoticed on shaded parts of your home.

Pressure washing in spring or summer eliminates these threats and helps restore your home’s beauty — and safety​​.

2. Benefits of House Washing in Late Spring

Late spring (think late April through May) is a sweet spot for many homeowners:

  • Ideal weather: Temps are usually above 50°F, perfect for washing and drying.
  • Beat the rush: Summer is peak season, so scheduling in spring means more flexibility.
  • Eliminate pollen and allergens: House washing in late spring clears away early-season pollen that’s stuck to siding and windows.
  • Prepares for summer activities: Planning backyard barbecues, graduations, or Memorial Day parties? Your home will be spotless and guest-ready.

Late spring is also a great time to inspect your home for any winter damage and tackle it early — before it gets worse or more expensive.

3. Advantages of Washing in Early Summer

Early summer (June into early July) offers some different perks:

  • Dryer conditions: Less rain means quicker drying times and longer-lasting results.
  • Peak mildew season: Warm, humid conditions make mold and algae grow fast — and pressure washing stops it in its tracks.
  • Boost curb appeal before a sale: Listing your home this summer? A clean exterior makes a powerful first impression.
  • Pair with other services: Many homeowners schedule deck, concrete, or roof cleaning at the same time for a complete refresh.

And let’s be honest: nothing beats seeing your home sparkle in the sunshine. A professionally cleaned house just feels like summer.

4. So, Which One is Better? Spring or Summer?

Here’s a quick cheat sheet to help you decide:
