How Often Should You Pressure Wash Your House in Texas?

If you've lived through a few North Texas summers, you already know the climate here doesn't go easy on a house. Between the humidity rolling up from the Gulf, the spring pollen that coats everything in yellow, and the relentless August sun, the outside of your home takes a beating that homeowners up north never have to think about.

So how often should you actually be washing it? The honest answer is: it depends on what part of the house we're talking about. Let's break it down the way we'd explain it to a neighbor standing in their driveway.

House washing (siding, brick, and stucco): once a year

For most homes in the Dallas–Fort Worth area, a full house wash once a year keeps things looking sharp and — more importantly — stops buildup before it does any real damage. That green or gray film you see creeping up the north-facing side of your house isn't just dirt. It's a living layer of algae and mildew that feeds on moisture and slowly works its way into the surface.

Catch it once a year with a proper soft wash and it never gets a foothold. Let it go for three or four years and you're looking at staining that's much harder (and more expensive) to reverse.

If your home sits under a lot of tree cover, backs up to a greenbelt, or has a side that never sees direct sun, you may want to bump that up to twice a year. Shade plus moisture is exactly what mildew is looking for.

Driveways and sidewalks: once or twice a year

Concrete is a magnet for everything — tire marks, oil drips, red Texas clay tracked up from the yard, and that dark organic gunk that builds up in the low spots after a rain. A driveway is also the first thing people see when they pull up to your home, which is why we get more calls about concrete than anything else.

Once a year is plenty for most folks. If you've got teenagers, multiple vehicles, or a basketball hoop that turns the driveway into a hangout, twice a year keeps it from looking tired.

Roofs: every 2 to 3 years (and don't DIY it)

Those black streaks running down your roof? That's a hardy little organism called Gloeocapsa magma — roof algae — and it loves the warm, humid stretches we get here. Left alone it doesn't just look bad; it actually shortens the life of your shingles by holding moisture against them.

A professional soft wash every two to three years clears it out without the high-pressure blasting that strips granules off shingles and voids roofing warranties. This is the one job we really don't recommend doing yourself — between the slick surfaces, the steep pitch, and the wrong-equipment risk, it's just not worth the fall.

The signs your house is overdue

You don't need a calendar to know when it's time. Walk the perimeter and look for:

• Green, gray, or black streaking on siding, especially low and on shaded sides
• A driveway that's noticeably darker than it used to be, or has a "shadow" where a planter or car used to sit
• Black streaks or dark patches on the roof
• A chalky, dull look to brick or stone that used to have some life to it
• Gutters with dark streaks running down the face ("tiger stripes")

If you're nodding along to two or more of those, you're past due.

Why "once a year" beats "once a decade"

Here's the thing most people don't realize until they've let it go too long: regular cleaning is cheaper than restoration. A yearly soft wash is routine maintenance. A decade of neglect turns into deep-set staining, permanently etched concrete, and sometimes surfaces that simply can't be brought all the way back.

Think of it like an oil change. Cheap and quick on schedule — expensive and painful when ignored.

A quick word on doing it yourself

We're not going to pretend a rented pressure washer can't get a driveway clean. It can. But two things trip up most DIY jobs in our area: using too much pressure on the wrong surface (hello, etched concrete and stripped shingles), and not having the cleaning solutions that actually kill algae at the root instead of just rinsing the top off so it grows right back.

That's really the difference between blasting dirt and treating a surface. The first looks good for a month. The second stays clean for a year.

The bottom line for DFW homeowners

• House wash: once a year (twice if shaded or tree-covered)
• Driveway & sidewalks: once or twice a year
• Roof soft wash: every 2–3 years
• Windows: twice a year for that always-clear look

Stick to a rhythm like that and your home stays in the top tier on your street without you ever having to think about it. If you're not sure where your home stands, we're happy to take a look and give you a straight, no-pressure assessment.
