How Long Does It Typically Take to Power Wash a House?

Maintaining the exterior of your home through power washing is an essential task that can dramatically enhance its curb appeal and longevity. If you’re considering hiring professional power washing services, one common question is: How long does it typically take to power wash a house? The answer depends on several factors, including the size of your house, the type of surfaces being cleaned, and the level of dirt and grime. Let’s dive deeper to understand what you can expect in terms of time commitment and efficiency.

Factors Influencing Power Washing Time

Several variables impact the duration of a power washing session. Understanding these factors can help you set realistic expectations and plan accordingly.

Size of the House

The most significant factor determining the time required for power washing is the size of your house. A larger home will naturally take more time to clean than a smaller one. Here’s a rough estimate based on the square footage of typical homes:

  • Small Homes (1,000-1,500 sq ft): Generally takes 1-3 hours.
  • Medium Homes (1,500-2,500 sq ft): Typically requires 3-5 hours.
  • Large Homes (2,500+ sq ft): Can take 5-8 hours or more.

Surface Material

Different materials require different approaches and timeframes for cleaning. For example:

  • Vinyl Siding: Generally quick to clean due to its smooth surface.
  • Brick or Stone: Takes longer because of the porous nature and need for deeper cleaning.
  • Wood: Requires careful attention to avoid damage, which can extend the cleaning time.

Level of Dirt and Grime

The amount of buildup on your house can significantly affect the duration of the power washing process. Homes with heavy dirt, mold, mildew, or algae will require more time and effort to clean thoroughly.

  • Light Dirt: Quick wash, often within a couple of hours.
  • Moderate Grime: Requires more detailed work, adding an hour or two.
  • Heavy Buildup: Extensive cleaning needed, potentially doubling the time.

Accessibility and Obstacles

Areas that are hard to reach or have many obstacles can slow down the power washing process. This includes:

  • Multiple Levels: Multi-story homes require additional time for setting up ladders or scaffolding.
  • Obstructions: Furniture, plants, and decorative elements need to be moved or worked around, adding to the time.

Professional vs. DIY

Hiring a professional power washing company generally results in a faster and more efficient cleaning process compared to DIY efforts. Professionals have the experience, equipment, and techniques to clean your home effectively in less time.

Typical Timeline for Power Washing a House

To provide a clearer picture, let’s break down the power washing process into its main stages and the typical time each stage might take.

1. Preparation (30 minutes to 1 hour)

Before power washing begins, several preparatory steps are necessary:

  • Inspection: Professionals will inspect the exterior to identify any areas needing special attention.
  • Setup: This includes setting up the equipment, laying out hoses, and preparing cleaning solutions.
  • Protection: Covering plants, outdoor furniture, and electrical outlets to prevent damage.

2. Washing (2 to 6 hours)

The core of the power washing process involves cleaning the exterior surfaces of your home. The duration depends on the factors discussed earlier.

  • First Pass: A preliminary wash to remove loose dirt and debris.
  • Deep Cleaning: Applying cleaning solutions and using high-pressure water to remove stubborn grime and stains.
  • Rinsing: Thoroughly rinsing the surfaces to remove any remaining cleaning solution and debris.

3. Final Touches (30 minutes to 1 hour)

Once the main cleaning is done, there are a few final steps to ensure everything is in order:

  • Inspection: Checking all cleaned areas to ensure no spots were missed.
  • Cleanup: Packing up equipment, removing protective coverings, and putting back any moved items.
  • Customer Walkthrough: Many professionals will walk you through the job to ensure satisfaction.

Benefits of Professional Power Washing

While DIY power washing can save money, hiring professionals offers numerous advantages that can ultimately save you time and ensure a better result.


Professional power washing companies have the tools and expertise to complete the job quickly and efficiently. They know the right techniques to use for different surfaces and can handle even the most challenging cleaning tasks.

Quality Results

Professionals provide superior cleaning results. They use high-quality equipment and eco-friendly cleaning solutions that are more effective than standard consumer products. This ensures your home’s exterior is thoroughly cleaned and looks its best.


Power washing can be dangerous if not done correctly. High-pressure water can cause injuries, and using ladders adds additional risks. Professionals are trained to handle these hazards safely, reducing the risk of accidents.


Hiring a professional service allows you to sit back and relax while the experts take care of everything. This convenience is particularly valuable for busy homeowners who don’t have the time or inclination to undertake such a labor-intensive task.

Choosing the Right Power Washing Company

When it comes to selecting a power washing company, it’s important to choose a reputable and experienced provider. Here are some tips to help you make the best choice:

Request Quotes

Start by requesting quotes from several power washing companies. Compare their services, pricing, and availability to find the best match for your needs.

Check Reviews and References

Look for customer reviews and ask for references to ensure the company has a track record of satisfied clients. Positive feedback and testimonials can provide insight into the quality of their work.

Ask About Services and Techniques

Different companies may use various techniques and equipment. Ask about their approach to ensure they use the appropriate pressure settings and cleaning solutions for your home’s exterior surfaces.

Verify Insurance and Guarantees

Make sure the company is insured and offers guarantees for their work. This provides peace of mind knowing that any potential damages or issues will be covered.
