What exterior cleaning includes, surface by surface

Why there is no one answer to what it costs or how long it takes

People search for exterior cleaning as though it were a single service, the way gutter cleaning is a single service. It is not. It is a category covering roughly a dozen jobs, and two of them can be as different as washing a window and degreasing a loading dock.

So this page is a map rather than a sales pitch. It lists what is actually out there on a property, what each surface needs, roughly how often, and which service covers it. If you only want the short version, skip to the table.

The one rule that explains every method

Force and chemistry trade off against each other. The harder and more porous the surface, the more pressure it tolerates and the less it needs help from a cleaner. The softer and more sealed the surface, the less pressure it tolerates and the more the cleaning solution has to do.

That is the whole principle. Concrete is hard and porous, so it takes high pressure and a surface cleaner. Vinyl siding is sealed and flexible, so it takes a solution and a rinse. Asphalt shingles are a layer of loose granules glued to a mat, so they take chemistry and nothing else. Once you have that, the rest of this page is just applying it.

It is also how you judge a company. Anyone who answers every surface with more pressure is going to damage something, and the difference between soft washing and pressure washing is the version of this worth reading in full.

Everything on a typical property

The surfaces people forget

There is a pattern to what gets skipped, and it is not about importance. It is about eye level.

• The roof, because you cannot see it from the driveway. It is usually the dirtiest surface on the house and the streaks are alive.
• The outside faces of the gutters, which develop a dark vertical striping that a house wash does not automatically include unless somebody asks.
• Second-story glass, which gets cleaned on the inside for years and never on the outside.
• The shaded walkway or patio at the back, which is where the growth is worst and where somebody eventually slips.
• Window screens, which hold a layer of pollen and dust that puts a gray film over glass you just paid to have cleaned.
• The garage floor and the apron, which is the single largest piece of concrete most people own.
• Fences, which get postponed until pickets need replacing rather than cleaning.

How to think about scheduling it

Nothing here runs on a calendar. It runs on conditions, and in the Triangle and Johnston County the conditions are humidity, tree cover, and pine. A north-facing wall under a canopy needs washing twice as often as a south-facing wall on an open lot at the same address.

What a full-property visit actually looks like

Top down, because anything you clean below a dirty surface gets dirty again when that surface is rinsed. Roof first, then upper siding, then lower siding and gutter faces, then windows, then flatwork last. A crew working in a different order is either rehandling surfaces or leaving runoff on finished work.

On a house in Clayton that usually means most of a day and one invoice. What happens on wash day covers the rest, including the ten minutes of prep worth doing before anyone arrives.

Where to start if you have never had any of it done

Get the roof and the gutters looked at, get the siding washed, and get the front flatwork cleaned. That is the version that changes how the property looks and removes the two problems that cause damage rather than just looking bad. Everything else can wait for a second visit once you know how fast your particular lot dirties.
