One of the most common questions we get from Conway homeowners is: how often should I pressure wash my house? The answer depends on your home’s location, surface types, and what’s growing on it. This guide gives you a Conway-specific maintenance schedule based on Arkansas’s climate.
The Arkansas Climate Factor
Conway, Arkansas creates ideal conditions for biological growth on exterior surfaces. The city averages 50+ inches of rainfall annually, summer temperatures regularly exceed 95°F, and humidity stays high from April through October. This combination accelerates mold, algae, and mildew growth significantly faster than drier climates. A home in Arizona might go 3–5 years between cleanings. A comparable home in Conway typically shows visible growth within 12 months.
Recommended Cleaning Frequency by Surface
| Surface | Conway Recommended Frequency | Signs It Needs Cleaning Now |
|---|---|---|
| House siding (vinyl) | Once per year | Green or black streaks, chalky appearance |
| House siding (brick) | Every 1–2 years | Green mold on mortar lines, dark staining |
| Concrete driveway | Once per year | Red clay staining, oil spots, green tinge |
| Roof (shingles) | Every 2–3 years | Black streaks running from peak to eave |
| Wood deck | Once per year | Gray weathering, slippery surface, mold spots |
| Gutters (cleaning) | Twice per year (fall + spring) | Overflowing during rain, visible plant growth |
| Fence (wood) | Every 1–2 years before re-staining | Gray weathering, green mold on posts |
Best Time of Year to Pressure Wash in Conway
Spring and fall are peak season for exterior cleaning in Conway for different reasons:
- Spring (April–May): After pollen season ends, before the humid summer heat. This is the most popular time — pollen covers every surface and needs to be removed before it bakes on. Cleaning in spring also removes winter mold before it gets a foothold for summer growth.
- Fall (September–October): Before leaf drop makes gutters a priority. Fall cleaning removes the summer’s mold and algae buildup before the wet winter. Decks benefit from a fall cleaning and sealing before cold weather sets in.
- Summer (June–August): Works but is brutal for crews and dries fast, which can affect cleaning solution dwell time. Avoid cleaning in direct sunlight on very hot days — solutions can dry before they’ve had time to work.
- Winter (December–February): Generally avoid unless temperatures stay above 40°F consistently. Freezing temperatures make cleaning dangerous and can crack wet concrete if it freezes before drying.
How to Tell If Your Conway Home Needs Cleaning Now
Walk around your home and look for these specific indicators:
- North-facing walls: Always check these first — they get the least sun and accumulate the most biological growth
- Under roof overhangs: Soffits and fascia in shaded areas develop black streaks quickly
- Driveway and walkway edges: Red clay and algae accumulate along edges near mulched beds
- Roof line: Step back and look for dark streaks running vertically down the shingles
- Deck boards: Slipperiness when wet is a safety issue and indicates algae growth even if not visible
What Happens If You Wait Too Long?
Skipping exterior cleaning for 2–3 years in Conway’s climate causes more than cosmetic problems:
- Black algae on roofs holds moisture and degrades shingles — manufacturers recommend soft washing every 2–3 years to maintain warranty coverage
- Mold behind vinyl siding (from water intrusion through damaged caulking) is expensive to remediate once it’s established
- Clogged gutters overflow and erode the foundation — a common source of basement moisture and structural issues
- Oxidized and algae-stained siding affects home value — appraisers and buyers notice dirty exteriors
