Power Washing Done Right

When it comes to giving your home’s exterior a fresh, clean look, few things are as satisfying as a good power wash. Over time, siding, decks, patios, and walkways collect layers of dirt, mildew, pollen, and grime—especially after a long New England winter and a wet spring. Power washing can bring surfaces back to life, but it’s not as simple as pointing and spraying. In fact, using the wrong pressure or technique can cause real damage.

So before you rent a machine or hire someone to tackle the job, here’s what you need to know to do it safely and effectively.

What Exactly Is Power Washing?

Power washing, sometimes called pressure washing, involves using a high-pressure stream of water to clean outdoor surfaces. Some machines use hot water (true “power washers”), while others use cold. Either way, the goal is the same: remove built-up dirt, mold, algae, and stains.

It’s commonly used on vinyl siding, wood decks, fences, concrete walkways, and driveways. Done properly, it can restore surfaces to like-new condition. But when done poorly, it can strip paint, dent siding, damage wood, or even force water behind your walls, causing moisture problems you won’t notice until later.

Why Technique Matters

The biggest mistake homeowners make with power washing is using too much pressure or holding the nozzle too close to the surface. While it might feel like you’re getting a deep clean, what you’re really doing is wearing away layers of your home.

Wood decks, in particular, are easy to damage. Softwoods like pine can splinter if blasted too hard. Vinyl siding can crack or become loose. Even concrete patios can show streaks or etching if the pressure is too high. Window seals, trim, and exterior caulking are all vulnerable to water intrusion if the spray angle is too aggressive.

The key to successful power washing is using the right amount of pressure and keeping a safe distance. Professionals typically start several feet away from the surface and gradually move closer, testing as they go. They also choose the correct spray tip for the job - wider angles for delicate surfaces, narrower ones for tough stains.

When It Works and When It Doesn’t

Power washing works well on most exterior materials - vinyl siding, concrete, brick, and certain types of wood. But it’s not ideal for everything. Asphalt roofing, older masonry with loose mortar, and painted surfaces that aren’t in great condition can be easily damaged. It’s also important to avoid spraying near electrical outlets, light fixtures, or windows.

Some surfaces benefit from using a cleaning solution before washing. Mildew and algae, common in shady areas or near trees, may require a cleaner designed for siding or decks. These help break down organic growth so that the power washer can rinse it away gently.

Know When to Call in a Pro

If your home is two stories tall, has delicate finishes, or hasn’t been cleaned in years, hiring a professional might be the safer option. A reputable company will know how to get the job done without harming your home’s exterior or landscaping. They’ll also have the right equipment for harder-to-reach areas.

Power washing can be a great way to refresh your home’s curb appeal, but it’s not a job to take lightly. With the right tools and a little know-how, you can do it yourself safely. And when in doubt, a professional can help protect your investment.

What To Do About Warped Siding

With Father’s Day happening this weekend and grills getting fired up all over the neighborhood, it’s a great time to talk about one of the most misunderstood siding issues I hear about: warped vinyl. Every summer, readers ask me why their siding looks “wrinkled,” even when it’s brand new. They usually blame the sun, the heat, or the frigid Connecticut winters. But here’s the kicker: warped siding isn’t a weather problem. It’s an installation problem.

The technical term for that unsightly ripple effect is “oil canning” or “stress buckling,” and it’s almost always the result of improper installation, not Mother Nature.

Vinyl siding is a fan favorite because it’s durable, low-maintenance, and looks great. But even the best-looking siding won’t hold up if it’s not put on right. Homes are built with natural materials like wood that expand and contract with the seasons. Siding needs to move with those changes. If it’s nailed too tightly, it can’t “breathe,” and that’s when it starts to buckle and warp.

Here’s another common mistake: overlapping the panels too much. It might seem like extra overlap equals extra strength, but it actually traps the siding, making it stretch and buckle when temperatures shift.

Now, back to that burning question: can the sun warp your siding? Not really. But there is one backyard culprit I’ve seen cause some serious damage: your grill. If you’re planning a Father’s Day cookout, do your siding a favor and keep that gas grill a good distance from the house. That seared steak isn’t worth melted siding.

Unfortunately, once siding starts to oil can, it needs to be replaced. Since the issue stems from how it was installed, the manufacturer’s warranty typically won’t cover it. And if your siding is a few years old, getting an exact color match might be tricky.

Bottom line: this is a job that requires know-how. Whether you’re hiring a pro or going the DIY route, make sure proper installation techniques are followed. You don’t want your home’s exterior to look like a wavy potato chip.

How to Find the Right Expert for the Job

If you’re not up for a DIY siding install (and really, who wants to spend Father’s Day up on a ladder?), here are a few quick tips to help you find a reliable contractor:

• Ask for experience specifically with vinyl siding. Not all siding is the same, and vinyl has its quirks. Make sure they’ve got a solid track record.

• Check references and reviews. Past customers are your best source of truth. Look for red flags like frequent callbacks or mention of warped siding.

• Make sure they’re licensed and insured. This protects you in case anything goes sideways, literally or figuratively.

• Ask about manufacturer certification. Some siding brands certify installers. This can improve your odds of proper installation and preserve the warranty.

• Get everything in writing. A detailed proposal should include materials, labor, timeline, and cost. If they can’t provide it, walk away.
