Power washing is an efficient cleaning technique designed to rid surfaces of dirt, mold, mildew, moss, and other contaminants. Furthermore, a power washing service helps prepare them for painting or staining, ensuring that it adheres correctly. But how long does it take to complete a pressure washing project on a home? The length of time may depend on a number of factors.

Size of the Home

Size plays an essential part in determining how long it will take to power wash your home. Large homes require more time than smaller houses as more surface area needs to be covered during cleaning. Furthermore, two-story houses require extra time in order to access hard-to-reach areas of their roof. Here’s a breakdown:

  1. 1,200 sq ft, 3 rooms – 1.5 to 2 hours
  2. 1,800 sq ft, 4 rooms – 2 to 2.5 hours
  3. 2,400 sq ft, 5 rooms – 2.5 to 3 hours
  4. 3,000 sq ft, 6 rooms – 3 to 3.5 hours
  5. 3,500 sq ft, 7 rooms – 3.5 to 4 hours
  6. 4,000 sq ft, 8 rooms – 4 to 5 hours
  7. 5,000 sq ft, 10+ rooms – 5 to 6 hours

If you want a beautiful-looking home with increased curb appeal, hiring a professional power wash service could be the way forward. The power washing process not only helps to power wash a house thoroughly but also ensures the removal of tough stains and dirt from exterior surfaces. The size of the house also explains how many times you should power wash your home.

Dirtiness of the Surface

Power washing with hot water is often more effective at dissolving dirt, grime, grease, moss, mildew, and algae than using cold water alone. This form of surface cleaning is much faster than manual scrubbing alone. Furthermore, adding chemical solutions can be especially helpful in getting rid of stubborn stains that won’t come away otherwise.

Although there are numerous methods for cleaning exterior surfaces, such as scrubbing and hand washing, power washing remains one of the best and most efficient means of getting them clean. Power washing can also help remove gum, oil stains and other hard-to-remove materials such as gum.

However, it is important to remember that not all surfaces can withstand its high pressure. Softer surfaces like natural stone, wood, and some types of siding may be damaged if too much pressure is used. Therefore, selecting appropriate equipment and levels of pressure for each surface must be carefully considered.

Type of Siding

Homes often feature wood, fiber cement, brick, stone, or stucco siding and require different approaches when it comes to washing them. You should never pressure wash wood siding unless it’s badly dirty due to high-pressure water causing irreparable damage. Different types of sidings need different cleaning processes. So, it’s wise to understand if pressure washing is better than power washing. Here are some types of sidings:

  1. Wood siding – 2 to 3 hours (soft wash recommended)
  2. Vinyl siding – 2 to 4 hours
  3. Fiber cement siding – 2.5 to 4 hours
  4. Brick siding – 3 to 5 hours
  5. Stone siding – 3.5 to 5.5 hours
  6. Stucco siding – 3 to 4.5 hours (soft wash preferred)

If your home features vinyl siding, professional pressure washing should be scheduled at least annually to protect it from dirt, mildew, and debris build-up. If your house produces pollen in abundance or its soffits are covered with cobwebs more frequently, you may need pressure washing services more regularly based on location and type of siding material used. Contact a professional for recommendations based on these factors.

Equipment Used

Power washing provides an effective and efficient means of reaching surfaces which cannot be reached using brushes or chemical solutions alone.

Professional power washers feature attachments that adjust the amount of pressure delivered and various nozzles with various spray patterns. So professionals know exactly how to safely and effectively utilize these tools without damaging materials underneath. In fact, each surface requires unique settings for maximum cleanliness without risk of material deterioration.

Why Does Power Washing Take So Long?

Power washing can seem like a lengthy process, but several factors contribute to the time it takes to pressure wash a house. The size and complexity of the home, along with the type of surfaces being cleaned, significantly affect the duration. Moreover, you should understand the best time to pressure wash your house.
