Maintences Beats Rescue! How Often Should I Power Wash My Home in Coastal Delaware?

The Quick, Clean Answer

How often should you power wash your home? There isn't one answer.

For many homes in Rehoboth Beach, Lewes, Bethany Beach and throughout Sussex County, an annual exterior cleaning is a good place to start. But where your home is located, what surrounds it, what it's made of and even which side of the house you're looking at can all change the answer.

A house surrounded by trees may collect pollen, algae and organic debris faster than one sitting in full sun. A home closer to the coast may deal with salt, sand and wind-driven moisture. Shaded areas stay damp longer. Driveways, decks, roofs, siding and fences all collect different things and shouldn't necessarily be cleaned on the same schedule—or in the same way.

So, instead of asking how often your home should be power washed, there may be a better question:

What is your home telling you?

Your House Doesn't Own a Calendar

Once a year. Twice a year. Every other year.

You'll find all kinds of recommendations for how often a house should be professionally cleaned.

And they're useful—as guidelines.

But your house doesn't know it's been twelve months since the last cleaning.

That’s because, it responds to its environment.

Humidity, rain, shade, trees, pollen, wind, dirt and our coastal location all affect exterior surfaces differently. Even neighboring houses can accumulate completely different kinds and amounts of buildup.

That's particularly true here in Sussex County.

A wooded property outside Lewes isn't exposed to exactly the same conditions as a beach house in Rehoboth. A year-round home may experience different use than a seasonal property in Bethany Beach.

And sometimes you don't even have to leave your own yard to see the difference.

Take a Walk Around Your House

Look at all four sides.

One side may look perfectly clean while another is developing green growth. Areas under trees may be dirtier than those exposed to full sun. The north-facing side may stay damp longer. A deck that receives little sunlight may become slippery while the driveway out front still looks fine.

That's your house giving you information.

Some common signs that it may be time for cleaning include:

• Green or dark discoloration on siding.
• Black streaks or growth on a roof.
• Slippery areas on decks, steps or walkways.
• Dirt and discoloration on concrete.
• Pollen collecting on siding, trim and outdoor surfaces.
• Buildup around gutters and rooflines.
• Staining on fences, patios and other exterior surfaces.
• Areas that simply don't look as clean as they used to.

You don't necessarily need to wait for the entire property to look dirty.

Sometimes one problem area needs attention before everything else does.

Coastal Delaware Adds Its Own Ingredients

Living near the Delaware beaches means enjoying an environment people travel hundreds of miles to visit.

Your house gets to live in it every day.

Humidity and rain provide moisture. Trees provide shade and organic debris. Spring brings pollen. Wind carries dirt and other material onto exterior surfaces. Properties closer to the water can also experience greater exposure to salt and sand.

Put those ingredients together and exterior buildup isn't particularly surprising.

That doesn't mean every coastal Delaware house needs to be power washed every six months.

It means location and exposure matter.

A property protected from some of those conditions may stay clean considerably longer than one that's constantly exposed to them.

That's why the calendar should be a guide—not the boss.

Different Surfaces Have Different Needs

There's another problem with putting your entire property on one cleaning schedule:

Your property isn't made out of one thing.

Consider how many different exterior surfaces you may have:

• Vinyl, aluminum, wood, brick or fiber cement siding.
• Asphalt, metal or cedar roofing.
• Concrete, asphalt or paver driveways.
• Wood or composite decks.
• Concrete, stone or paver patios and walkways.
• Wood, vinyl or composite fencing.

They don't get dirty in exactly the same way, and they shouldn't automatically be cleaned in exactly the same way.

A concrete driveway may tolerate a cleaning method that would be completely inappropriate for cedar siding. A roof with organic growth presents a different problem than an asphalt driveway with surface dirt.

That's why professional exterior cleaning isn't simply about deciding when to clean.

It's also about knowing what you're cleaning.

Maintenance Beats Rescue

It’s common to wait until exterior buildup becomes impossible to ignore.

Green siding. Black streaks. A slippery walkway. A deck that's gone from weathered to what happened out here?

But regular exterior cleaning doesn't have to be an emergency response.

Think of it as maintenance.

Cleaning buildup before it becomes severe can help keep your property looking better, make developing problems easier to spot and prevent contaminants from being allowed to sit indefinitely on exterior surfaces.

It can also make maintaining a seasonal or second home easier. You shouldn't have to arrive at the beach and discover that your first weekend project is cleaning everything outside.

The goal isn't to clean your property more often than necessary.

It's to clean it when necessary.

So, How Often Should You Power Wash?

For many Sussex County homes, looking at exterior cleaning on an annual basis makes sense.

But don't circle a date on the calendar and stop paying attention.

• Walk around your property occasionally.
• Look at the shady side of the house.
• Check the deck.
• Look up at the roof.
• Take a look at the gutters, driveway, patio, walkways and fences.
• Your home will usually give you some clues.
• And when it does, the next question isn't simply whether you should power wash it.

It's how that particular surface should be cleaned.

Because concrete isn't asphalt.

Wood isn't vinyl.

A roof isn't a driveway.

And knowing the difference is every bit as important as knowing when it's time to clean.

Clean What Needs Cleaning. Protect What Doesn't.

At Sussex Pro Wash, we don't believe every surface needs maximum pressure or every property needs the same cleaning schedule.

We match the cleaning method to the surface, the buildup and the conditions we're dealing with using the appropriate combination of professional cleaning solutions, water volume, controlled pressure and heated water when the job calls for it.

If you're not sure whether your Rehoboth Beach, Lewes, Bethany Beach or Sussex County property is ready for cleaning, we'll help you figure out what needs attention—and what can wait.

Because good maintenance isn't about doing more.

It's about doing the right thing at the right time.
