If your vinyl siding is covered in green algae, black mildew, or chalky oxidation, it is actively hurting your home’s curb appeal — and potentially its value. In New Jersey’s humid coastal climate, organic growth on siding is nearly inevitable without regular professional cleaning. The good news is that professional vinyl siding cleaning is more affordable than most homeowners expect, and A+ Power Washing has been delivering results for Monmouth and Ocean County residents since 1990.
This guide breaks down exactly what you can expect to pay, what drives the cost, and how to get an accurate estimate for your specific property.
Pricing for vinyl siding cleaning depends on the size of your home, the height of the structure, the level of buildup, and any additional surfaces like covered porches or detached garages. Based on our current pricing for Monmouth and Ocean County, New Jersey, here is what you can expect:
There is a minimum service charge of $399 for all jobs. This reflects the real cost of deploying a fully equipped commercial hot-water rig and trained technicians to your property. Bundling multiple services — such as adding a driveway cleaning or deck wash — is the best way to maximize value on that minimum.
Professional house washing rarely stops at just the siding. Here is a full breakdown of common add-on services and their estimated price ranges for New Jersey properties:
| Service | Typical Size | Estimated Price Range |
|---|---|---|
| House Washing (Small) | Up to 1,500 sq ft | $285 – $399 |
| House Washing (Large) | 2,500+ sq ft | $714 – $966 |
| Driveway / Concrete Cleaning | 400 – 800 sq ft | $200 – $400 |
| Deck Cleaning | 200 – 500 sq ft | $168 – $420 |
| Roof Cleaning | Up to 2,000 sq ft | $850 – $1,150 |
| Gutter Surface Washing | Per story | $163 – $326 |
| Patio / Walkway / Pool Deck | 200 – 600 sq ft | $100 – $300 |
No two homes are exactly alike, and several key variables determine where your final price falls within the ranges above.
Total square footage and home height are the biggest cost drivers. A two-story home requires extended wands, additional safety equipment, and more time than a single-story structure of the same square footage. Multi-story homes will fall toward the higher end of the price range.
The condition of the siding also plays a significant role. Heavy, long-standing algae and mildew growth requires stronger treatment solutions, longer dwell times, and more rinse passes than light seasonal buildup. A home that has not been washed in five or more years will cost more than one that is cleaned on a regular maintenance cycle.
Covered porches, garages, and additional structures add to the total. A covered porch requires measuring and cleaning the ceiling, floor, walls, and railings — all of which are priced separately from the main siding. Detached garages, sheds, pool patios, balconies, and awnings can all be added to create a fully customized service package.
Accessibility and location can affect pricing when unusual terrain, tight spaces, or difficult access points require extra setup time and equipment.
A professional house wash from A+ Power Washing uses hot water and professional-grade, eco-friendly cleaning solutions to safely remove algae, mildew, mold, and oxidation from vinyl siding without causing damage. Our soft-wash technique applies controlled pressure appropriate for the surface, protecting your siding, windows, and surrounding landscaping throughout the process.
Optional service upgrades that can be bundled into your vinyl siding cleaning include:
A professional vinyl siding cleaning performed by an experienced contractor with the right equipment and solutions will typically keep your home looking clean for two to three years, depending on your property’s exposure to humidity and tree coverage. Spread across that timeframe, professional siding cleaning costs roughly $0.30 to $0.55 per day — a small investment to protect your home’s curb appeal, structural integrity, and resale value.
Green algae and black mildew are not merely cosmetic problems. Left untreated, organic growth can cause siding to deteriorate prematurely and create conditions that promote moisture intrusion. Regular cleaning is one of the most cost-effective home maintenance tasks available to New Jersey homeowners.
