Pressure washing a driveway is one of the most effective ways to remove dirt, moss, algae, oil stains, and general grime. A clean driveway not only improves curb appeal but also prevents long-term damage caused by mold and moss. For a 100 ft driveway, costs vary depending on whether you hire a professional or do it yourself. This guide breaks down all the costs, considerations, and factors you need to know to make an informed decision.
Why Driveway Cleaning Is Important
Driveways get dirty over time. Leaves, dirt, moss, oil stains, and algae gradually accumulate. If left untreated, these can make the surface slippery and unsafe. They also cause discoloration and permanent staining, especially from oil or chemical spills.
Regular driveway cleaning preserves the surface, extends its lifespan, and maintains a neat appearance. Moss and mold can slowly erode concrete or pavers. Pressure washing removes these hazards efficiently. Clean driveways also increase property value. For homes preparing for sale or those wanting a fresh look, cleaning makes a noticeable difference.
Average Professional Cost
Professional driveway cleaning typically costs between $150 and $900. Prices depend on the driveway’s size, surface type, and condition.
Most professionals charge either per square foot or by total job. On average, expect $0.50–$3 per square foot for concrete or asphalt surfaces. Brick, stamped concrete, or paver driveways may cost more because they require extra care.
The driveway’s condition also affects cost. Light dirt and moss are easier to remove, while oil stains or heavy moss may require more time and stronger detergents.
Per Square Metre Pricing
Some professionals prefer to charge per square metre, which is common outside the U.S. Rates usually range from $5 to $20 per m².
For example, a 100 ft long driveway that is 10 ft wide equals about 930 square feet, which converts to roughly 86 m². At $5 per m², the cost is around $430. At $10 per m², the cost rises to $860.
Per square metre pricing helps homeowners estimate total cost more accurately, especially for longer or wider driveways.
Total Estimate for 100 ft Driveway
Combining pricing methods, you can expect a professional cleaning of a 100 ft driveway to cost between $150 and $900.
Lower-end estimates assume minor stains and a clean concrete surface. Higher-end estimates cover stubborn oil stains, heavy moss, or specialized surfaces such as brick or pavers.
Professionals may also charge extra for optional driveway sealing after cleaning. Sealing helps protect the surface, making future cleaning easier and preventing damage.
DIY Cost Breakdown
Cleaning your driveway yourself can save money but requires more time and effort. Here’s a breakdown of common DIY costs.
Machine Rental Cost
Pressure washers can be rented for $40–$100 per day. Electric models are cheaper but have lower pressure. Gas-powered washers offer higher pressure, making them more effective for tough stains but heavier and harder to handle.
Detergents
Cleaning detergents cost $10–$30 per bottle. Stronger chemicals may be required for oil or moss stains. Always read and follow safety instructions, especially for chemical cleaners.
Water Usage
Pressure washing consumes a significant amount of water. Gas machines typically use 8–10 gallons per minute. Cleaning a 100 ft driveway may require 500–1,000 gallons. In areas with metered water, this can add to costs.
Total DIY Cost
When adding rental fees, detergents, and water usage, the DIY cost ranges from $60 to $150. It’s cheaper than hiring a professional but requires physical effort and time.
Professional vs DIY Comparison
Cost
Professionals cost $150–$900 depending on driveway size, surface, and stains. DIY costs $60–$150, saving money but requiring effort.
Time
Professionals complete the job faster, usually 1–3 hours for a 100 ft driveway. DIY can take 4–6 hours, or longer if inexperienced.
Quality
Professionals have industrial-grade equipment and experience, removing tough stains more effectively. DIY results vary depending on skill, effort, and equipment quality.
Factors That Affect Pricing
Surface Type
Concrete is easier and cheaper to clean. Brick, pavers, stamped concrete, or textured surfaces require more care, increasing labor and cost.
Stains (Oil, Moss)
Oil stains need stronger chemicals and extra scrubbing. Moss or algae may require specialized cleaners and extra water. Tough stains add to the total cost.
Location
Urban areas are usually more expensive than rural ones. Travel distance, labor costs, and local demand also influence pricing.
Is It Worth Hiring a Professional?
Hiring a professional is worth it if your driveway has stubborn stains, heavy moss, or is large. Professionals save time and ensure high-quality results.
DIY works well for moderately dirty driveways and for homeowners willing to invest time and effort. While DIY saves money, professionals can prevent damage caused by improper cleaning techniques. For long-term maintenance, occasional professional cleaning is a good investment.
FAQ
How long does it take?
For a 100 ft driveway:
- Professionals: 1–3 hours
- DIY: 4–6 hours, depending on experience and equipment
How often should it be cleaned?
At least once a year. For areas prone to moss or heavy oil stains, cleaning twice a year is recommended. Regular maintenance prevents permanent damage, maintains curb appeal, and keeps the driveway safe for walking and driving.
Pressure washing a driveway is a simple but effective way to improve appearance, prevent damage, and maintain property value. Costs vary widely depending on surface type, stains, location, and whether you hire a professional or do it yourself. Understanding these factors helps homeowners make the best choice for their driveway, budget, and time.
