A Power Washing Problem

This time of year, you can spot it all over town. The first warm weekend hits, someone drags out a power washer, and suddenly every surface around the house is getting blasted.

On the surface, it feels productive. The house looks cleaner and the grime disappears. You stand back and think, great, my spring cleaning is done. The problem is, power washing is one of the easiest ways to accidentally damage your home if you don’t know what you’re doing.

I see it every spring. The biggest misconception is that more pressure equals a better clean. But it really means you’re forcing water into places it shouldn’t go or stripping away materials that are supposed to protect your home.

Take siding, for example. Vinyl siding is designed to shed water, not withstand high-pressure spray at close range. Aim a pressure washer upward or get too close, and you can drive water behind the panels. That moisture gets trapped and over time it can lead to mold, mildew, and even rot in the structure underneath.

Wood is even less forgiving. We’ve seen plenty of decks and trim that looked fine before a weekend cleaning and came out rough, splintered, and permanently damaged. Once you tear up the surface fibers of wood, you can’t undo it. You’re sanding, repairing, or replacing it entirely.

Then there are windows. High-pressure water can break seals, force moisture into frames, and shorten the lifespan of the window itself. Again, it might not show up immediately, but it’s the kind of damage that creeps in over time.

And don’t forget about paint. A pressure washer in the wrong hands can strip paint right off siding and trim. Sometimes people think they’re “prepping” a surface and end up creating a much bigger project than they planned for.

So what’s the right way to do it?

First, understand that most homes don’t need high pressure at all. What they need is the right cleaning solution and a controlled rinse. A soft wash with low pressure, combined with a cleaner that breaks down dirt, algae, and mildew is usually far more effective and a lot safer. One of my favorite products is Wet It and Forget it which doesn’t require any pressure washing at all and is great at removing common outdoor stains and grime.

Second, distance matters. Standing too close is where most of the damage happens. If you’re using a pressure washer, keep your distance and let the water do the work gradually instead of trying to blast everything off in one pass.

Third, know what you’re cleaning. Concrete can handle pressure. Your siding, trim, windows, and deck? Not in the same way. Treating everything the same is where people get into trouble.

Lastly, timing matters. Early spring is a great time to clean up your home’s exterior but it’s also when materials are still coming off a long winter. They’re not always in their strongest condition, which makes aggressive cleaning even riskier.

The goal here isn’t to scare you off from cleaning your house. It’s to do it in a way that actually helps instead of quietly creating problems you won’t notice until later. If you’re going to power wash this spring, ease up on the trigger. Your house will thank you for it.

Maintain Your Stone Patio for Decades of Use

Two years ago, I replaced my wood deck for a stone patio. After almost 30 years, I was ready for a new look and the deck itself was coming to the end of its life. But after decades of cleaning, staining, and sealing wood, I wasn’t quite sure how to maintain my bluestone. Luckily, I am now an expert! Here is what I learned as a newcomer to patio protection.

The one thing that makes a patio a bit riskier than a wood deck is that they are laid right on the ground instead of on a platform, which means that any shifts or movement in the earth can cause cracks and splits between the joints or the stone itself. Additionally, weeds are unbelievably strong little pests. After time, they always find a way to creep through the joints. Brick patios are especially susceptible to weed infiltration and ants love making their homes in the gaps too. Luckily, sealing a stone patio on a regular basis is a surefire way of keeping both pests and weak points at bay.

You can start with a thorough cleaning not unlike the process you might be used to for a wood deck. Begin by removing any debris and loose dirt and dust with a firm broom, and then fire up the pressure washer. Stone can be stained from rusty patio furniture so be sure to pretreat and scrub down any marks before giving it a good power wash. Leave it to dry for at least 24 hours.

Next, inspect the joints closely. This is a tougher job for bricks than larger stone, but it’s important to repair any erosion or loose pieces before you apply your sealant. Otherwise, the stone will become uneven and the gaps will invite weeds and ants to make their homes inside. You can use sand to fill any spaces that have deteriorated over time.

Now you’re ready to seal. Each product is different so you’ll want to pay close attention, especially when it comes to finishes. I always look for a high quality, water-based sealant that I can spray on easily. I recommend applying two thin coats and waiting 24 hours between applications to ensure you achieve an even finish. Wait another 24-48 hours after the final coat to put patio furniture, grills, and any other equipment back on the surface.

This may seem like a lot of work, but if your patio isn’t susceptible to too much environmental exposure, you can get away with a good clean and seal every other year. Trust me, the effort is worth it and will extend the life of your patio for years to come.
