Pressure Washing Cost Factors

Here’s how your home’s square footage, material, and other factors influence your pressure washing costs in St. Louis, MO.

Cost to Pressure Wash a House per Square Foot

Pressure washing costs $0.09 to $0.45 per square foot, depending on what part of your property you’re cleaning. Flat, easily accessible surfaces like driveways and patios take less effort and therefore cost less.

Note that pressure washing only a small area means that a technician will spend very little time at your home, but they still have to pay for gas, insurance, and all other overhead costs. For this reason, pressure washing costs less per square foot when you give a professional more to do. So, take some time to look around your property and think about everything that could use some spiffing up.

Here’s how much it might cost to pressure wash a 1,500 square foot house, 2,000 square foot house, or 2,500 square foot house:

How Often Should You Pressure Wash Your House?

You should pressure wash your home once per year, and the best time to pressure wash is between March and November in most areas. These months rarely have temperatures that dip too low, so the risks of freezing water and cold temps damaging the machines is low. That said, demand is higher in the spring and summer, so you could experience longer wait times for a professional to come (and possibly higher costs).

Here’s how often you should pressure wash different areas of your home:

Area of HomeBest Time to Pressure WashReason
SidingSpring or fallMild temperatures, less risk of mold and mildew buildup
DrivewaySpring or fallAfter winter snow or fall leaves to remove debris and grime

Pressure Washing Pro Costs

Before hiring a pro and kicking off your pressure washing project, keep these final expenses in mind.

Labor

Prepare to pay between $45 and $136 per hour for professional pressure washers in St. Louis, MO. Your labor costs will depend on the size and difficulty of the project (among other factors). Pros often include the cost of labor in their quotes, but you’ll want to confirm this ahead of time.

Licensing

Pressure washing companies must have a business license to operate in the city of St. Louis. They should also have general liability and workers’ compensation insurance. When hiring a pressure washer, make sure they meet these requirements.

Does Pressure Washing Your House Increase Home Value?

Pressure washing is a quick and easy way to improve your property’s curb appeal before putting it on the market. By investing in this type of maintenance, you’ll ensure that your home looks its best for potential buyers, which can help you pull in more money from your sale. And while pressure washing is always worth considering before selling a house in St. Louis, it’s especially smart after a wet winter, when mold, mildew, and grime often build up on your home’s exterior.
