Power washing your house can dramatically improve its curb appeal, removing dirt, grime, mold, and mildew. But before you grab your pressure washer, it's helpful to understand how long the job will take. The answer, unfortunately, isn't a simple number. The time required depends on several key factors. This guide will break down those factors and help you estimate the time needed to power wash your home.
Factors Affecting Power Washing Time
Several variables significantly impact the duration of a house power washing project:
-
House Size: This is the most obvious factor. A small bungalow will take considerably less time than a large two-story home with multiple additions. Think about the total square footage of the exterior walls, including any outbuildings you plan to clean.
-
House Style and Features: A simple, single-story ranch with few architectural details will be faster to clean than a Victorian home with intricate trim, multiple levels, and ornate features. These details require more attention and careful maneuvering of the pressure washer.
-
Surface Condition: Is your siding heavily soiled? Is there significant mold or mildew growth? Extensive buildup will require more time for pre-treatment and thorough cleaning. Severe staining or damage may necessitate additional steps, further increasing the time needed.
-
Pressure Washer Type and Power: A more powerful pressure washer will generally work faster, but be careful! Too much pressure can damage your siding. Using the appropriate pressure and nozzle for your siding material is crucial.
-
Number of People: Having an extra person to assist with pre-treatment, rinsing, or spot cleaning can significantly reduce the overall time.
How Long Does it Take to Power Wash a House of Average Size?
For a typical single-story house (around 1500-2000 square feet of exterior wall space) with average soiling, a professional power washing crew might take 4-6 hours. This estimate includes preparation, cleaning, and rinsing. A DIY project, especially for a novice, could easily take 8-12 hours or more, depending on the individual's experience and efficiency.
What About Larger or Smaller Houses?
-
Smaller Houses: A very small house could be power washed in as little as 2-3 hours by a professional or 4-6 hours as a DIY project.
-
Larger Houses: Large homes or those with extensive landscaping or multiple structures might take 8-12 hours or longer for professionals and potentially an entire day or even longer for DIY projects.
How Long Does Pre-Treatment Take?
Pre-treatment is crucial for effective power washing, especially when dealing with stubborn mold, mildew, or algae. This process can add anywhere from 30 minutes to several hours, depending on the severity of the contamination and the size of the house. The pre-treatment solution needs adequate time to penetrate and break down the grime before power washing.
Can I Power Wash My House Myself?
You can absolutely power wash your house yourself, but be prepared for a considerable time commitment and the potential for mistakes if you’re inexperienced. Improper pressure or technique can damage your siding or windows. Renting or purchasing a pressure washer and the right cleaning solutions are also factors to consider. Weigh the cost and time savings against potential risks.
What is the Best Time of Day to Power Wash a House?
The best time is typically on a cloudy day or during the early morning or late evening to avoid direct sunlight, which can cause the cleaning solution to dry too quickly and leave streaks. Avoid power washing when it's raining or windy to maintain safety and effectiveness.
How much does it cost to power wash a house?
The cost depends greatly on the size of the house, the level of cleaning needed, and your location. Getting several quotes from local companies is advisable before proceeding.
By considering these factors, you can get a more realistic estimate of how long it will take to power wash your house. Remember to prioritize safety and proper technique to achieve the best results without damaging your property.
