If you live in the Fraser Valley, you already know the pattern: wet seasons, shade, and tree cover can make a home look dull faster than expected. Roof moss shows up along edges, siding starts turning green on the shaded side, gutters overflow during heavy rain, and windows never look finished when the screens are dirty.
This guide is a simple, premium-level checklist for homeowners in Chilliwack, Abbotsford, Mission, Agassiz, Harrison Hot Springs, and Hope so you know what to clean, when to clean it, and what to watch for.

Why Exterior Buildup Happens So Fast Here
The Fraser Valley’s moisture and mild temperatures create ideal conditions for organic growth. When surfaces stay damp, especially under trees or on north-facing areas, moss, algae, and lichen develop faster.
The result is not just cosmetic. Heavy buildup can trap moisture, contribute to gutters filling faster, and leave staining on siding and exterior finishes that gets harder to remove the longer it sits.
1) Roof Cleaning — Moss, Algae, Lichen, and Black Streaks
What to Look For
green moss along roof edges and valleys
rough crusty patches, often lichen
dark streaking that makes the roof look aged
debris collecting in valleys and near gutters
When to Clean
Many homeowners book roof cleaning in spring after winter or late summer to early fall before heavy rain season. If you have heavy tree cover or shaded roof slopes, maintenance may be needed more often.
Pro Tip
Avoid aggressive blasting on shingles. Roofs need roof-safe methods, not maximum pressure. If you are already seeing roof warning signs, it also helps to read Signs You Need Roof Cleaning in Chilliwack Before Costly Repairs.
2) House Washing — The Green Side of the House
What to Look For
green algae staining on shaded siding
grime lines under soffits and around downspouts
cobweb buildup around corners and entry areas
dull, tired-looking siding, even if it is not heavily dirty
When to Clean
A soft wash house wash every 1–2 years keeps most homes looking sharp. Homes with heavy shade often benefit more frequently.
Pro Tip
Soft washing is the premium approach for siding because it cleans thoroughly without relying on harsh pressure that can force water behind exterior materials.

3) Gutter Cleaning — Prevent Overflow Before It Starts
What to Look For
overflow during rain
water pouring over corners
streaking on fascia and siding
plants growing out of the gutter
When to Clean
For most Fraser Valley homes, spring and fall are the best times. If you have a lot of trees, adding an extra cleanout can help before storm season.
Pro Tip
If your roof has moss, consider pairing roof cleaning and gutter cleaning. Roof debris often ends up in the gutters.
4) Window + Screen Cleaning — The Finished Look
What to Look For
rain spotting and film on exterior glass
dirty screens that block light and airflow
windows that still look dull even after you wipe the glass
When to Clean
Many homeowners choose 2–4 times per year, depending on exposure, landscaping, and preference.
Pro Tip
If you want a premium finish, don’t skip the screens. Clean glass looks incomplete with dirty screens. For a closer look at why this makes such a difference, read Window Cleaning in Chilliwack & Hope | Benefits of Screen Cleaning.
