How Often Should You Wash Your House in Mission?
Your home is your safe haven. It’s where you kick back after long days, make memories with loved ones, and protect yourself from the unpredictable elements of nature. But here’s the question: are you protecting your home as much as it protects you?
If you live in Mission, BC, you know that our damp winters, heavy rains, and humid conditions create prime breeding grounds for dirt, moss, mold, and grime to build up on your home’s exterior. And this isn’t just an aesthetic issue — it’s a serious threat to your home’s structural health and value if left unchecked.
So how often should you wash your house in Mission, and why does it really matter? Grab your coffee (or your garden hose) because we’re diving into everything you need to know to keep your home clean, strong, and looking its best in Mission’s unique climate.
Why Keeping Your Home Clean in Mission Is Non-Negotiable
Mission’s weather patterns are the perfect storm for exterior buildup. Here’s why exterior cleaning here isn’t just “nice to have” — it’s essential:
Moisture breeds moss and mold
Persistent rain and overcast conditions encourage mold, mildew, and moss growth that eat away at siding, roofing, and wood.
Algae & mildew cause health risks
Beyond looks, exterior mold can trigger allergies and asthma if it spreads indoors.
Dirt wears down surfaces
Wind-blown dust, grime, and pollutants can act like sandpaper, damaging surfaces and dulling paint over time.
Curb appeal boosts home value
Whether you’re selling or just maintaining your pride of ownership, a clean, bright exterior makes a huge difference.
Preventative maintenance saves money
Regular washing prevents expensive repairs like wood rot, cracked siding, or early roof replacement.
In short? It’s way cheaper and easier to clean your home consistently than to fix major problems down the line.
So… How Often Should You Wash Your House?
The answer depends on your home’s location, surroundings, and materials. That said, here are some solid guidelines:
At Least Once a Year
If nothing else, plan a full wash at least once a year. This removes a year’s worth of grime, moss spores, pollutants, and weather residue.
Best time:
Late spring or early summer, after winter storms and before the peak summer dry season.
Twice a Year for High-Risk Homes
Homes that sit under large trees, near shaded areas, or in damp parts of Mission will need cleaning twice a year. Shady areas trap moisture, encouraging faster growth of algae, mildew, and moss.
Recommended timing:
- Spring: Remove winter buildup and prepare for summer.
- Fall: Remove summer dust, pollen, and debris before winter rains arrive.
Spot Cleaning Every 4–6 Months
Focus on high-traffic or high-exposure areas:
- Decks
- Walkways
- Driveways
- Gutters
- Entryways
These areas collect grime much faster and benefit from quarterly maintenance.
When’s the Best Time to Wash Your Home?
Spring and Fall are Mission’s best seasons for house washing.
Spring
Ideal for clearing winter grime, prepping siding, and preventing algae/mold expansion.
Fall
Clean off summer dust, pollen, and debris to prevent trapped moisture in winter.
Avoid freezing conditions. Cleaning during winter’s cold snaps risks water freezing onto your surfaces — leading to more damage than dirt ever could.
Soft Washing vs. Power Washing: Which Is Best?
There are two main exterior cleaning methods:
| Type | Best For | Pros | Cons |
|---|---|---|---|
| Soft Washing | Siding, roofs, delicate surfaces | Safe for all materials, removes mold/algae deeply | Needs professional-grade cleaners |
| Power Washing | Concrete, brick, patios, driveways | Great for heavy grime and oil stains | Too aggressive for house siding, risks damage |
Rule of thumb:
If you’re cleaning your home’s siding, roof, or decks — soft washing is the way to go.
Professionals like Top Dawg Pressure Wash in Abbotsford specialize in soft washing techniques that preserve your home’s surfaces while removing stubborn grime safely.
Signs It’s Time for a House Wash in Mission
Sometimes it’s obvious; sometimes it’s more subtle. Watch for:
Black or green streaks on siding or roofing
- Moss or mildew patches growing along walls or patios
- Discolored driveways and sidewalks
- Musty odors near your home’s exterior walls
- Peeling paint or wood damage
- Gutter overflow or blockages
If you notice two or more of these signs, it’s definitely time to book a wash.
Dealing with Mold, Algae, and Moss in Mission
Mission’s moisture-rich climate is paradise for mold and moss. But it’s a nightmare for homeowners.
Why it matters:
- Moss damages roofs and decks by lifting shingles or trapping moisture in wood.
- Algae dulls paint and siding. Over time, it chemically breaks down exterior coatings.
- Mold impacts indoor air quality once it finds its way into your home’s envelope.
Solutions:
- Schedule regular washes.
- Apply preventative mold inhibitors after cleaning.
- Trim back trees and bushes to allow more sun exposure.
Professional cleaners like Top Dawg Pressure Wash not only clean but also treat surfaces to help slow regrowth — saving you time and future expenses.
5 Quick Pro Tips for Keeping Your Mission Home Cleaner Longer
Inspect Your Home Twice a Year
Look for moss growth, gutter clogs, and exterior stains.
Trim Overhanging Branches
More sunlight = less moisture = less moss and mold.
Clean Gutters Regularly
Clogged gutters cause water damage to siding and foundations.
Use Mildew-Resistant Paints
If repainting, opt for paints that resist algae and mildew buildup.

Light annual cleanings keep problems from ever starting — especially in Mission’s rainy seasons.
