How to Pressure Wash a House: A Step-by-Step Guide

By taking these steps, you ensure a safe, efficient, and hassle-free cleaning process. For houses with more than two stories, setting up scaffolding is a smart move. It’s safer than using a ladder (which we never recommend), as the force of the water can throw off your balance. Scaffolding provides a stable platform, allowing you to reach high areas without the risk.

Steps to Pressure Washing a House

It’ll cost about $70 to $100 per day, and expect to keep it for a full day. You don’t have to be experienced to use one but be prepared for a day of physical labor. The washer will probably be gas-powered and weigh more than 75 lbs. Depending on its size, you might need a pickup or van to haul it and help to unload it. Ask the rental agent to show you how to hook it up and operate it, and to review safety precautions with you.

How To: Stain Pressure-Treated Wood

The type of pressure washer you select can make a big difference in both the ease and effectiveness of the job. Let’s step into the world of pressure washing and start the journey to a cleaner, brighter home. Don't pressure wash your home if you think it's been painted with lead paint. To find out if your home might've been painted with lead-based paint, purchase a test kit or contact a professional for an inspection and recommendations. Pressure washers will remove loose paint, but they’re not a substitute for scraping.

Finishing Your Cleaning Project

To reach places over-head, plug a lance extension into your machine rather than using a ladder. "The kickback could easily knock you right off of it," Manke explains. If you still can't hit the mark, hire a pro, who can do the job safely with scaffolding. The kickback from the washer can make you lose your balance. If you need to reach high areas, use an extension wand instead.

Preparing Your House for Pressure Washing

Following the steps carefully will ensure that your house is dirt and mildew free when you’ve finished the chore. Be sure you assemble all necessary materials before you start; take the time to protect plants, doorways, and windows; scrub the siding; and then start pressure washing. If you’re planning to paint, remember to time the washing properly so the siding can dry for a couple of days before you start applying paint or stain.

STEP 1: Cover surrounding greenery and seal doors and windows.

Apply it with a spray bottle, gently brush the area, and rinse with clean water. The angle of the nozzle affects how concentrated the water stream is. A wider angle means a softer spray, which is better for delicate surfaces.

It’s similar to sanding down a piece of furniture before repainting it. Keep the high-pressure spray away from windows and exterior vents. If you hold the nozzle too close or for too long in one spot, you’ll gouge the wood. We’ll have to fill this area with wood putty before repainting.

Steps

To remove more set-in stains or mold, or tackle an entire house, go with a gas-fueled type with a PSI of 2,500 to 3,000. For the best results when pressure washing gutters, set your machine for a high-pressure spray pattern. Rinse the surfaces of the gutters with clear water to reduce the spots and streaks caused by water, detergent and grime that splashes from other areas of the house. Remember, pressure washing isn’t just pointing a hose at your house and spraying. It requires the right equipment, technique, and a bit of planning. Whether you choose a gas or electric model, the key is to use the right pressure settings and nozzles for your home’s specific needs.

It’s natural to want to know more about this process, especially if you’re doing it for the first time. With these measures in place, you can focus on the rewarding aspects of pressure washing, knowing you’ve taken steps to safeguard yourself and your surroundings. Pressure washing is about patience and attention to detail. By following these steps, you can ensure a thorough clean that rejuvenates your home’s exterior, all while keeping things safe and efficient. Preparing your pressure washer properly is essential for a safe and effective cleaning session. If you have a two-story home, consider investing in accessories such as spray tips and extensions that are designed to help you clean upper stories.

First, inspect your house for any areas that might need more attention. Sometimes, pressure washing reveals spots that require extra cleaning or even repairs. This is particularly true for older homes where the high pressure might have uncovered hidden issues. After pressure washing your house, there’s a sense of accomplishment.

Use the more forceful 15-degree (yellow) one for stub-born regions, and the gentler 40-degree (white) one for soft materials like wood. A washer with a PSI rating of 1,000 to 1,500 is usually quite sufficient for washing siding. If you have a two-story house, a high-volume gas pressure washer fitted with a special nozzle will allow you to clean the upper areas while standing on solid ground. By keeping these points in mind, you can ensure that pressure washing your house is a rewarding experience.

The actual washing process, done in sections from the bottom up, can transform the look of your house, clearing away years of dirt and grime. After washing, if you’re planning to paint, give your house time to dry and prepare it properly for the best results. By following these tips, you can ensure a safer pressure washing experience. Safety precautions are not just about personal protection; they also contribute to the effectiveness and efficiency of your cleaning task. Patch damaged joints and allow the patches to dry for at least a week before you clean the house.

When power washing vinyl siding or other rugged, unpainted materials like brick, stone, and steel, it’s recommended to use a machine rated for 2,500 to 3,000 psi. Pressure washing fiber cement siding is not recommended and may void the siding’s warranty. If you opt to pressure wash this kind of siding, be sure to use less than 1,500 psi—and a wide nozzle. Keep in mind there are some areas you'll want to avoid when power washing your house. "Regardless of the type of exterior you're cleaning, avoid getting detergent or water behind the outer surface," Macfarlane explains.

If you’re planning to repaint, you’ll definitely want to pressure wash first to prepare the surface. For areas with a lot of trees or exposure to pollution, you might need to do it more often. Think of pressure washing like a regular health check-up for your house. By taking these post-wash steps, you’re not just cleaning your house; you’re preparing it for a fresh start.
