Power Washing 101: What You Should (and Shouldn’t) Blast Around Your Home
So, you’ve got a power washer—or you’re thinking about hiring someone with one—and suddenly, every surface on your property starts to look like a good candidate for a blast. We get it. There’s something ridiculously satisfying about watching layers of dirt, algae, and grime disappear in seconds. But before you go wild and start pressure washing everything in sight, there’s a little know-how that goes a long way.
AtDri-Masters, we’ve handled our fair share of power washing projects across Maryland, Pennsylvania, and New Jersey. And we’ve seen the good, the bad, and the “uh-oh, that wasn’t supposed to peel like that.” If you’re wondering what’s safe to wash and what’s better left alone—or just need a refresher on how it all works—this one’s for you.
What Power Washing Is (and Why It’s Not Just for Curb Appeal)
Power washing (also called pressure washing) uses a high-powered stream of water to remove dirt, mold, mildew, algae, and other built-up grime from hard surfaces. It’s great for making your home look sharp, sure—but it’s also a form of preventative maintenance. Getting rid of that green gunk growing on your siding or walkways doesn’t just look better, it can help preserve your surfaces and even extend their lifespan.
We offer fullpressure and soft washing servicesdesigned to clean safely and effectively—no unnecessary wear and tear, just that “like-new” shine you’re after.
Go Ahead—Blast These Surfaces Without Worry
When done right, power washing can safely clean a variety of exterior surfaces. Here are a few things around your property that are usually safe to wash with the proper technique and pressure level:
Concrete driveways and sidewalks: These can take the heat. They’re tough, and power washing can make them look brand-new. If you haven’t seen your concrete this clean in a while, check out ourconcrete cleaning service.
Decks and fences: Depending on the material, wood can be washed gently with a soft wash technique or low pressure. It’s a great way to prep for staining or just keep things tidy. You can learn more on ourdeck and fence cleaning page.
Brick or stone patios: These materials can handle higher pressure and benefit from a thorough clean—just be careful around the mortar joints.
Exterior siding: Vinyl, fiber cement, and certain types of wood siding can all be cleaned safely with low-pressure soft washing, which is what we recommend forexterior home cleaning.
Roofs (with soft washing only): Yep, roofs can be cleaned—but not with high pressure. We use a soft wash system that clears moss, algae, and buildup without damaging shingles. You can read about our approach toroof cleaning.
Think Twice Before Power Washing These
Not every surface is a good candidate for pressure washing—at least not at high power. Some things need a gentler approach or a completely different cleaning method. Here’s what we recommend avoiding:
Windows and glass doors: You might get away with it once, but that kind of pressure can easily crack seals or cause breakage. Better to clean these by hand.
Old or brittle wood: If your fence or siding is starting to splinter just from looking at it, keep the power washer at bay.
Painted surfaces you want to keep painted: Unless you’re prepping for a repaint, high-pressure water can strip paint right off—and not always evenly.
Delicate landscaping: This one seems obvious, but trust us—it’s easy to accidentally point the wand at your flower beds or shrubbery and do some real damage.
If you’re unsure whether your surface is safe to clean, we’re happy to help you make that call. You can alwaysschedule a consultationand we’ll assess it for you.
DIY vs. Hiring a Pro: When to Call in the Big Guns
We get it—power washers are available for rent, and the DIY route can be tempting. But here’s the deal: without proper experience, it’s pretty easy to cause unintended damage. We’ve had clients come to us after etching their concrete, stripping paint, or accidentally waterlogging their siding.
When you hire a pro (like our team at Dri-Masters), you’re not just paying for the equipment—you’re getting the know-how that ensures the job is done right, safely, and without any surprises. Our crew understands different surfaces, local weather patterns, and how to match the method to the material.
