"Leo came over to give me an estimate on my jobs: gate repaired, outdoor wooden steps rebuilt, power washing of the house & brick patios & walkway. They cleaned out my outdoor fountain for free & did an excellent job of the other work. Rick & Cody did the work & were very friendly & professional. I would definitely recommend them for household work. I will call them again in the future."

Pressure Washing questions, answered by experts

This answer is a bit tricky because experts say both. You should apply your cleaning solution from bottom to top, but rinse from top to bottom to avoid streaking. When it comes to multi-story houses, you’ll want to start at the top floor and work your way down, but follow the above instructions for each level as if it were an independent structure, rather than washing the whole house as one unit.

You’ll need to wait until the surface is completely dry, which can take anywhere from 24 to 48 hours under optimal conditions. The waiting period depends on several factors, including the type of siding and the weather conditions. Trying to paint before the surface is completely dry can trap moisture under the paint, leading to bubbling, blistering, and mold growth.

It depends on the type of surface, but if you’re preparing to pressure wash a driveway, you’ll start by using a broom or leaf blower to get rid of dirt, leaves, and other debris. Then, move any nearby items (like outdoor furniture and potted plants) and cover in-ground plants with a tarp or plastic sheet. After that, you can apply degreaser spray or another pretreatment solution to any stains and scrub them with a stiff brush before pressure washing.

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.
