Houston is hard on exteriors.
Heat, humidity, clay soil and a growing season that barely pauses. Surfaces here don't just get dirty — they get colonized, and the difference decides how you clean them.
Why the same house needs this more often here
A house in Phoenix gets dusty. A house in Houston grows things. That single difference is why exterior cleaning here is a maintenance category rather than an occasional treat.
We sit in a humid subtropical climate on expansive clay, with mild winters that never really stop the growing season. Algae, mildew and lichen have moisture and warmth available to them almost year-round, and they don't sit on a surface so much as attach to it.
Add irrigation systems running hard water over glass and brick, sudden heavy rainfall that overwhelms gutters, and soil that swells and shrinks under every slab, and you get a set of problems that are specific to this city.
- 01 Humidity feeds organic growth. Anything shaded or north-facing greens up first and fastest.
- 02 Hard water etches glass. Sprinkler overspray leaves mineral deposits that only get harder to remove with time.
- 03 Rain arrives all at once. Gutters that trickle in spring overflow in a August thunderstorm.
- 04 Clay soil moves. Concrete settles, joints open, and water finds every one of them.
- 05 The season never ends. Live oak sheds most of the year. There is no single autumn cleanup that covers it.
Two methods, chosen by the surface
Almost every mistake we're called in to fix comes from using the wrong one.
Soft washing
Low pressure, a cleaning solution, and dwell time. The chemistry kills organic growth at the root rather than knocking the top layer off it, so the surface stays clean for far longer.
Used on: siding, stucco, brick, painted surfaces, soffits and eaves, stone, and anything with a seam that water shouldn't be forced into.
House washing and soft washingPressure washing
Controlled pressure, correct tip, correct distance, and an even pass. Right for hard flat surfaces that can take it, wrong for almost everything vertical on a house.
Used on: concrete driveways, walkways, patios, pool decks, and hardscape where the substrate genuinely calls for mechanical cleaning.
Pressure washing
What a Houston exterior looks like when it's actually maintained
Not restored once and forgotten — kept, on a rhythm the climate dictates rather than one a calendar invented.
When to do what
Most homes here don't need more work. They need it at the right time of year.
-
Late winter — glass
Before pollen season, and while the weather is still comfortable enough to open the house afterwards.
-
Late spring — gutters
After live oaks finish shedding. The single most important clearing of the year, ahead of hurricane season.
-
Early summer — house wash
Get ahead of the worst humidity rather than reacting to what it leaves behind.
-
Late summer — hardscape
Driveways, walkways and pool decks, when growth in the joints and shaded areas is at its heaviest.
-
Fall — gutters and glass
The second clearing, plus the window clean that carries the house through the holidays.
We don't claim all of Houston
Plenty of companies list every suburb in the metro. Most of them are quoting jobs they'll subcontract or arrive late to.
Bellaire Pro Wash runs a tight radius from Bellaire — roughly twenty to thirty minutes — which covers Bellaire, West University Place, Southside Place, River Oaks, Memorial, Meyerland and a good deal of inner-loop Houston around them.
We regularly take work in Braeswood, Tanglewood, Rice Military, the Heights, Sugar Land and Pearland. Beyond that we'll look at the job on its merits — a multi-day exterior project justifies a longer drive in a way a single-story window clean doesn't.
If we can't service a property properly, we say so. An arrival window we can't hold and a return visit we can't make quickly is worse than an honest no.
Four questions worth asking anyone you hire
- One What method will you use on my siding, and why? If the answer is "pressure wash" for every surface, keep calling.
- Two What do you do about my plants? Beds should be soaked before and rinsed after. Companies that skip this kill landscaping.
- Three How will you document the property and completed work? The company should be able to explain what it records before and after service.
- Four What won't come out? Anyone who says everything will clean up hasn't looked closely at your property.
We publish ours on The BPW Standard — the method, the protection, the documentation, and the list of things we tell homeowners will not come out.
