How Often Should You Pressure Wash Your Northshore Home?
In New Orleans & the Northshore, LA, our warm, humid weather is beautiful but tough on siding. Algae and mildew love shade, rain, and nearby trees. That is why most local homes benefit from routine cleaning year-round. The simplest way to keep your curb appeal high and your exterior protected is by scheduling professional house washing on a smart, predictable rhythm.
What Really Determines Your House Washing Schedule
No two homes weather the elements the same way. The right cadence for cleaning depends on a handful of local factors we see every day across Mandeville, Covington, Slidell, Madisonville, Abita Springs, Metairie, and Kenner.
- Shade and trees: Live oaks and pines drop pollen and hold moisture, which speeds up algae growth.
- Rain and humidity: Frequent showers and summer humidity let mildew take hold faster.
- Proximity to lakes and bayous: Waterfront breezes carry organic material that settles on siding.
- Traffic and construction dust: Busy roads and new builds add a fine film that dulls paint.
- Surface type: Vinyl, Hardie, stucco, brick, and painted wood each respond differently.
If your home has heavy shade, sits near water, or backs up to trees, expect buildup to return sooner. In those cases, many Northshore homeowners choose a twice‑a‑year plan to stay ahead of staining and streaks.
A Simple Rule Of Thumb For Local Homes
For most houses in New Orleans & the Northshore, plan on a thorough exterior cleaning once a year as a baseline. Homes with extra shade or heavy pollen often benefit from a spring and fall rhythm. This schedule keeps algae from becoming established, which helps paint, caulk, and trim last longer between repaints.
Many of our customers pair annual siding care with occasional concrete cleaning and gutter care. Keeping the full exterior clean reduces slippery growth on walkways and protects your investment.
The Best Seasons To Book In Our Climate
Timing matters. Spring and fall bring mild temperatures and fewer afternoon storms, which makes for efficient cleaning and dry times. Early spring is ideal to rinse away pollen and winter debris. Early fall works well after a long, rainy summer.
Booking before peak pollen or just after the wettest stretch of summer helps your clean stay fresher, longer. If your home sits under big oaks in Mandeville or near the water in Slidell, consider locking in both seasons on your calendar so you are never playing catch‑up.
How Material And Design Change The Cadence
Different exterior materials react to moisture and sun in their own way. That affects how often you should clean and the technique a pro will use.
- Vinyl and PVC trim: Resist water but show algae streaks quickly in shade. Annual soft washing keeps them bright.
- Painted wood and fiber cement: Hold up well with gentle cleaning. If you have heavy shade, a spring and fall plan prevents stains from setting into paint.
- Stucco: Porous and prone to blotchy discoloration. Gentle, low‑pressure treatment at least once a year keeps color even.
- Brick: Durable but can harbor dark biological growth in mortar joints. A yearly rinse keeps mortar looking sharp.
Avoid high pressure on siding and trim. Professional soft washing targets organic growth with the right mix and low pressure to protect finishes.
Neighborhood Examples Across New Orleans & The Northshore
We see patterns repeat from one area to another:
In shaded streets of Old Mandeville and Covington’s historic districts, tree cover means faster algae returns. In Slidell and Madisonville near rivers and bayous, moisture lingers after rain, which encourages mildew. On the Southshore, parts of Lakeview, Gentilly, Mid‑City, and Uptown collect pollen and road dust that make light‑colored paint look dull sooner.
These microclimates do not make annual care complicated. They simply help you choose whether once a year is enough or whether you should schedule both spring and fall to keep things looking new.
Signs Your Home Needs Cleaning Sooner
You do not need to wait for a full schedule if these show up between services:
Look for green film, black streaks, or chalky residue on shaded sides of the house. You may also notice slippery spots on steps or walkways after a rainy week. A timely cleaning prevents permanent stains and keeps surfaces safer underfoot.

Why Professional Care Beats Waiting Another Season
Delaying cleaning lets growth spread and roots set into porous surfaces. Over time, that can shorten the life of paint and sealants. Professional care is all about matching the right technique to each surface so your home looks better for longer.

Your Northshore House Washing Timeline At A Glance
Use this as a starting point and adjust up or down based on tree cover and shade:
- Annual plan: one full exterior cleaning each spring.
- Enhanced plan: spring and fall if you have heavy trees, shade, or waterfront exposure.
- After major weather: schedule a visit if you see streaks or widespread residue following long rainy stretches.
Remember, the goal is not just a quick refresh. It is to prevent buildup from bonding to surfaces, which protects your paint and preserves curb appeal from season to season.
Common Questions Homeowners Ask Us

Yes, soft washing targets the organic growth that causes most staining without risking damage to your siding.
Those benefit from their own cleaning rhythm based on foot traffic, shade, and irrigation overspray.
If you are comparing timing with neighbors in Abita Springs or Kenner, remember that tree cover, irrigation, and waterfront breezes can make two houses on the same street need different schedules. That is normal for our area.
A Smarter Way To Stay On Schedule
