The Fraser Valley Exterior Cleaning Checklist (What to Clean + When)

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 isn’t 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/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 max pressure.

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’s not “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 (it happens)

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 + 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.
