Get matched with top pressure washers in Gray, ME

It’s not necessary, but you can absolutely use soap or detergent when pressure washing your house. Washing with a mixture of soap and water will ensure your siding is spotless when you’re finished. However, in many cases it is not necessary to use soap and you can still achieve a powerful result without any product. 

It takes about 15 minutes per each side of an exterior house to apply detergent and 15 minutes to remove it, so you’ll need roughly two hours for the whole job. However, that length of time may decrease or increase depending on the size of your home, so always budget a little more than expected to ensure you don’t end up rushing to get it done.

Whether you need to winterize your pressure washer depends on where it will be stored. If it's kept in a location where temperatures could drop to freezing, any liquid left in the water pump can freeze, expand, and cause severe damage to the machine. To prevent this, you can add antifreeze to the pump. While emptying the machine with compressed air is an alternative, it can be a tedious process and may not remove all the liquid. If you can store the pressure washer in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, regardless of storage conditions, it is good practice to empty the gas chamber and refresh the oil before storing it for the winter.

The average cost to pressure wash a house is around $310, with typical prices ranging from $200 to $420. However, the total cost can vary widely, from $200 to $750. Power washing, which uses heated water, may cost between $250 and $400 per project, with an average of $200 to $300 for a 2,000-square-foot home.

Key factors that influence the final price include:

• The size and height of the house (a multi-level home costs more than a single-story one).

• The complexity of the job and accessibility of certain areas.

• Geographic location.

• Equipment and hourly labor costs.

Hiring a professional is often recommended as they bring their own equipment and cleaning solutions. Experienced professionals know how to complete the job effectively without causing damage to your siding, gutters, or landscaping, which can be a risk with high-powered water jets.
