Which Surfaces Can Be Pressure-Washed?

By following these steps, you can set up your pressure washer effectively, ensuring a smooth and safe cleaning process. In this guide, we’ll cover the steps to get your house looking its best. From preparing your home and setting up the washer, to the actual washing and post-care. We’ll answer common questions and offer tips to ensure a successful clean.

Service Pros

Pressure washers can cause catastrophic lacerations when they cut through clothing and skin, even at low pressure. To prevent injury, a homeowner needs eye protection, a face shield, solid shoes, feet on the ground—and some luck. The house will look better from the street when the trim is pristine, the siding gleams, and the driveway and walkway are clean and welcoming.

Visible Mold or Mildew

It’s a powerful tool, and just like using a power drill, you need to be careful. When it comes to pressure washing, many homeowners have questions. It’s natural to want to know more about this process, especially if you’re doing it for the first time. With your equipment ready, it’s time to move on to the pressure washing itself.

Mastering Effective Pressure Washing Techniques

But pressure washing them removes water stains, blasts out clogs in the downspouts, and removes buildup in the seams and joints that collect other debris that can lead to clogs. Clogged gutters are no joke—they can lead to leaks and failures and cause leakage inside the house; they can also invite birds and pests to nest in the clogs. Sometimes it seems like mold and mildew can develop overnight. One day, the shady back of the house is clean and fresh, and just a couple of rainy days later it’s coated with a hazy green film of algae and mold, or the blackish gray staining of mildew. Every home has a side or face that doesn’t get any sun, so mold and mildew are likely something you’ll have to deal with at some point or another.

Choosing the right equipment for pressure washing your house is crucial. It’s not just about power, but also about suitability and safety. While it’s an efficient way to refresh your home’s exterior, it’s not as simple as pointing a hose and watching the magic happen. This method can breathe new life into various surfaces like stucco, wood, and brick.

Pressure washers (aka power washers) can be gratifyingly money-saving, too. With the rising cost of construction materials these days, power-washing an old, stained deck can alleviate the need to build a new one—and potentially save you thousands of dollars. Power washing a concrete patio costs $120 to $240, depending on the size.

In order to request useful estimates, homeowners will need to consider the following aspects of their pressure washing job. Many contractors include a minimum charge to make sure the job covers the materials, travel, and labor—in other words, they’ll need to make sure the job is worth their time. The main distinction between power washing and pressure washing is heat.

Pressure washers are available in gas and electric models; the gas variety can create greater psi and is advised for tougher jobs and hardier material. Because they don’t have to be plugged into an electrical outlet, gas pressure washers are also more mobile, so they’re better suited for hard-to-reach areas. A pressure washer is one of the best time-saving tools to come along in years. Its high-velocity water spray cleans dirt, grime and chalking paint from otherwise sound-painted surfaces. Pros like pressure washers not only because they’re fast, but because they scour the old paint so the new coat will adhere better.

How CR Tests Pressure Washers

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. The widest nozzle draws detergent from the receptacle; if you're washing a vertical surface (like a wall), go from bottom to top. To power-rinse, switch to the 25-degree nozzle (green) and sweep it from the top down in overlapping passes, avoiding windows and frames. Use the more forceful 15-degree (yellow) one for stub-born regions, and the gentler 40-degree (white) one for soft materials like wood.

There are differences between power and pressure washing that are important to understand before hiring a pro. If you’re looking to use a pressure washer for the occasional job and aren’t interested in storing or maintaining it, renting may be the better choice. Homeowners who want to use one more often will find they’ll get a return on their investment after a year or so. But homeowners living near a busy road, with lots of surrounding trees, or where it’s generally dusty, stormy, and windy might need to do it in the spring and fall.

Not all types of house cladding hold up well to the strong force of pressurized water. Great care must be taken when pressure washing wood siding because it’s soft and can easily crack or splinter under the force. Aluminum siding can easily lose its finish or dent under the pressure. As a result, the cost of pressure washing wood or aluminum siding is a bit higher because it takes more time and care to do safely. Vinyl siding can be pressure washed more quickly and is therefore less expensive; however, it must still be done properly, because like wood, vinyl siding can be damaged by the pressure. If the house is covered with fiber cement siding, pressure washing isn’t recommended and may even invalidate the warranty.

A simple pressure washing of concrete runs from $0.08 to $0.20 per square foot. Prices increase to $0.25 to $0.35 per square foot if the pavement is greasy and requires power washing (the addition of hot water) plus a concrete detergent. The detergent breaks up dirt, grease, and oil and makes the pressure wash easier and faster.

To power wash, stain, and seal your deck, expect to pay $0.50 to $1.50 per square foot. The average cost to pressure wash a driveway is $155 to $190 total or $0.25 to $0.35 per square foot. Some companies offer a flat price per driveway at $100 to $200, depending on the size.

Pressure washing gutters adds approximately $50 to $300 to the pressure washing bill, averaging out to about $0.50 to $1.50 per linear foot. This requires the use of an extension wand and a specific nozzle to target trouble spots inside the gutter. Should the gutters develop ice dams during colder weather, a power washer can use heated water to blast away ice for about twice the cost of a regular wash. Simple jobs such as pressure washing a 1-story home that’s moderately dirty won’t be particularly taxing for technicians, so the cost will be toward the lower end of the range. Adding other elements to the project, however, can make the project more cost-effective.

If you knock old lead paint loose, it will settle permanently in your soil, where it can get kicked up by children playing outside or can be tracked into your home. Composite decks from brands such as TimberTech and Trex often resist deep staining and clean nicely with a light scrub, followed by a rinse with a garden hose. But if that isn’t enough, check the terms of the warranty to make sure pressure-washing won’t void it.
