How long it takes to pressure wash a house depends on a range of factors. H&N Cleaning Services, a trusted local leader in residential exterior cleaning, released this statement to educate Winston-Salem homeowners about the length of a power washing job.
The company is committed to transparency and helping residents make informed decisions about maintenance.

Factors That Influence Pressure Washing Time
Most people know that house size and cleaning duration are linked, but there are other things to consider. How long it takes to pressure wash a house depends on:
- Size and design of the house: The average pressure washing time increases as the home’s size does, but people have to factor in the design as well. A small Victorian-style property can take longer than a large contemporary house because of the multifaceted roof and the number of details.
- Type of siding material: The time to clean exterior siding depends on what it’s made of. Vinyl is typically quicker to wash than brick because it isn’t porous. When cleaning brick, the team needs to allow the cleaning solution to soak into the capillaries and lift out the dirt.
- Degree of dirt, mold, and mildew buildup: The more muck the team must work through, the longer the job takes. This is why the first session may be a lot longer than subsequent ones.
- Accessibility and layout challenges: Things may take longer for multi-story buildings or tight landscaping since the team must set up extra safety precautions.
- Weather conditions and drying times: It’s better to clean during mild weather or on an overcast day. Otherwise, the heat from the sun evaporates the water, leaving soap marks and leading to extra rinsing.
The team will assess these factors to give homeowners an accurate pressure washing time estimate.
Average Time Estimates
The average duration for residential pressure washing is:
- Small home of under 1,500 square feet: 1.5–2 hours
- Medium home of 1,500–2,500 square feet: 2–4 hours
- Large home of 2,500+ square feet: 4–6+ hours
According to Kenneth Nash, the owner of H&N Cleaning, “We can assess how long a job will take when we see what we’re dealing with. If there’s heavy staining or delicate surfaces, it can take longer. Clients can rest assured that we always use the safest and most efficient process.”
The Importance of Professional Expertise
Homeowners may be tempted to save money by attempting DIY pressure washing. According to the Power Washers of North America, it’s essential to work with a professional team as DIY cleaning comes with the risk of:
- Surface damage
- Injury
- Incomplete cleaning
Holding the nozzle too close to the surface can gouge wood and shatter windows.
