When it comes to maintaining a rental property, most landlords focus on the interior—repairs, appliances, and tenant-ready touch-ups. But the exterior plays an equally important role in curb appeal, property longevity, and tenant satisfaction. One of the most effective ways to preserve your property’s exterior is by scheduling regular deep exterior cleans.
So how often should you do it—and what exactly should it include?
What Is a Deep Exterior Clean?
A deep exterior clean goes beyond casual tidying or seasonal touch-ups. It includes a thorough cleaning of various outside surfaces and structures, such as:
- Siding (vinyl, wood, brick)
- Roof and gutters
- Driveways and sidewalks
- Decks, patios, and fences
- Exterior windows
- Garage doors and trim
- Outdoor lighting fixtures
The goal is not just to make the property look good, but to remove harmful buildup like mold, mildew, algae, moss, pollen, and grime that can cause long-term damage.
Why It Matters for Rental Properties
- Curb appeal: Clean exteriors make your property more attractive to current and prospective tenants.
- Preventative maintenance: Regular cleaning extends the life of exterior materials, reducing costly repairs.
- Health and safety: Mold, mildew, or moss can be slippery or trigger allergies.
- Property value: A clean, well-kept exterior contributes to the overall value and reputation of the property.
Recommended Cleaning Frequency
The ideal frequency depends on your region, building materials, and nearby environmental factors. But here’s a general guide for most rental properties:
Annually (Once Per Year)
- Pressure washing siding and hardscape (driveways, patios, walkways)
- Gutter and downspout cleaning
- Exterior window washing
- Soft washing roof if needed (consult a pro)
Biannually (Twice Per Year)
- Gutter cleaning (especially in fall and spring)
- Inspection of roof, siding, and foundation for buildup
- Light exterior window touch-ups (especially if pollen or dust is heavy)
As Needed (Trigger-Based)
- After major storms or heavy seasonal pollen
- Prior to tenant move-ins or listing the property
- When moss, algae, or bird droppings become visible
Pro tip: Keep a maintenance calendar and log cleanings to track patterns and needs across seasons.
Factors That May Affect Frequency
- Climate: Humid, rainy, or coastal areas often need more frequent cleaning due to higher moss and mildew growth.
- Trees and landscaping: Overhanging branches and leaf buildup speed up grime accumulation.
- Proximity to roads: Properties near busy roads collect more dust and debris.
- Building material: Wood and stucco may require gentler, more frequent cleaning than brick or vinyl.
Signs It’s Time for a Deep Exterior Clean
Watch for these visual cues:
- Green or black streaks on siding or fencing
- Overflowing or sagging gutters
- Slippery walkways or decks
- Dull or discolored paint
- Pollen build-up on windows and frames
Even if the property “doesn’t look too bad,” a yearly deep clean can prevent issues that aren’t yet visible.
Should You Hire Pros or DIY?
While some tasks like sweeping walkways or cleaning porch lights can be done in-house, deep exterior cleaning often involves ladders, water pressure equipment, and specific cleaning agents.
Hire a pro if:
- The property is multi-story
- You’re cleaning roofs or delicate materials
- You want bundled services (e.g., windows + gutters + siding)
RentalRiff can help coordinate these bundled exterior services as part of your ongoing maintenance plan—ensuring they’re done safely, correctly, and without extra hassle on your part.
DIY works best for:
- Single-story homes
- Spot cleaning between deep cleans
- Owners with experience and the right equipment
Reminder: Improper pressure washing can cause damage to siding, windows, or paint—especially with high PSI.
Keep It Consistent, Not Reactive
Deep exterior cleaning isn’t just about looks—it’s about protecting your investment. When it’s done consistently, it prevents wear, boosts tenant satisfaction, and reduces the likelihood of costly fixes.
Booking annual or biannual cleanings as part of your routine property maintenance helps you stay ahead of grime, buildup, and potential damage.
Your property doesn’t have to look run-down before it gets cleaned. Set a schedule, stick to it, and let clean exteriors be one of the quiet signals that your rental property is well cared for.
