Power washing your house can significantly improve its curb appeal, removing dirt, grime, mold, and mildew. But before you grab that pressure washer, you're probably wondering: how long will this take? The answer, unfortunately, isn't a simple one. The time it takes to power wash a house varies considerably depending on several factors.
Factors Affecting Power Washing Time
Several key factors influence the total time required to power wash a house:
-
House Size: This is the most obvious factor. A small bungalow will naturally take far less time than a sprawling two-story Victorian. Larger houses with multiple stories and complex architectural details will require more time and effort.
-
Surface Area: Even two houses of similar square footage can take different amounts of time. A house with extensive siding, multiple decks, and intricate trim will demand more attention than a simpler structure with smooth surfaces.
-
Surface Condition: The condition of your home's exterior greatly impacts the job's duration. Heavily soiled surfaces with significant mold or mildew buildup will require more pre-treatment, scrubbing, and rinsing, adding considerable time to the process. Conversely, a relatively clean house might require only a quick wash.
-
Pressure Washer Type and Power: A high-powered professional-grade pressure washer will generally work faster than a smaller, consumer-grade model. The power of the machine directly influences cleaning speed and efficiency.
-
Number of People Working: While a solo operation is possible, having a team of two or more people can drastically reduce the overall time required. One person can focus on pre-treatment and applying cleaning solutions while another operates the pressure washer.
-
Weather Conditions: Unfavorable weather, such as strong winds, rain, or extreme heat, can significantly slow down the process and may even necessitate rescheduling the entire job. Ideally, choose a calm, mild day for optimal efficiency.
How Long Does it Typically Take?
While pinpointing an exact timeframe is impossible, here's a general guideline:
-
Small House (under 1500 sq ft): 2-4 hours with one person, potentially less with a team.
-
Medium House (1500-2500 sq ft): 4-8 hours with one person; 2-4 hours with a team.
-
Large House (over 2500 sq ft): 8+ hours with one person, significantly less with a team. This could easily take multiple days, especially with complex architectural features.
Remember that these are rough estimates. Unexpected issues like stubborn stains or difficult-to-reach areas might add extra time.
What if I need to clean specific areas?
How long does it take to power wash a deck?
The time required to power wash a deck depends on its size, condition, and material. A small deck might take an hour or two, while a large, multi-level deck could take considerably longer.
How long does it take to power wash a driveway?
Similar to decks, driveway power washing time varies based on size and condition. A small driveway could be cleaned in under an hour, while a long, expansive driveway might take several hours.
How long does it take to power wash siding?
Siding power washing time depends on the house's size and the type of siding. Vinyl siding is usually faster to clean than wood siding, which often requires more care and attention.
Should I DIY or Hire a Professional?
Whether you choose to DIY or hire a professional depends on your comfort level, available time, and the complexity of your house's exterior. Hiring a professional often saves time and ensures a thorough, high-quality job, but it comes with a higher cost. DIY offers cost savings but requires more time and effort.
Ultimately, the time required to power wash your house is highly variable. Consider the factors mentioned above for a more accurate estimation for your specific situation. Remember safety first; always prioritize safety precautions when using a pressure washer.
