Your home’s exterior is exposed to weather, dirt, pollen, moisture, algae, mildew, and other contaminants throughout the year. Over time, that buildup can make even a well-maintained property look dirty and neglected.
One of the easiest ways to refresh your property is professional house washing or exterior pressure washing. But how often should you actually have your house cleaned?
For many homes, professional exterior cleaning every 12 to 24 months can be a useful maintenance schedule. However, the right frequency depends on your home’s location, surrounding environment, exterior material, weather conditions, and how quickly organic growth develops.
Old Fireman’s Services provides professional pressure washing and soft washing for residential and commercial properties throughout Northern Virginia, Maryland, the Eastern Panhandle of West Virginia, Southern Pennsylvania, and surrounding areas.
What Causes a House Exterior to Get Dirty?
Your siding and other exterior surfaces are constantly exposed to the elements.
Common causes of exterior buildup include:
- Dirt and dust
- Pollen
- Mud and soil
- Algae
- Mold and mildew
- Cobwebs
- Bird droppings
- Water stains
- Organic debris
- General weather-related grime
Moisture is particularly important. Areas that stay damp or receive limited sunlight may develop algae, mildew, or other organic growth more quickly.
Homes surrounded by trees can also collect more pollen, leaves, and organic debris than properties in open areas.
Signs Your House Needs Professional Washing
You don’t necessarily have to wait until your home’s exterior looks extremely dirty.
- Green or Dark Streaks Are Appearing
Green, gray, or dark discoloration on siding can be a sign of algae or organic buildup. These areas are particularly common on portions of the home that remain shaded or damp.
- Your Siding Looks Dull
Sometimes there isn’t one obvious stain. Instead, the entire exterior gradually becomes darker and less vibrant. A professional exterior cleaning can remove accumulated dirt and buildup and restore a cleaner appearance.
- Mold or Mildew Is Visible
Visible mold or mildew shouldn’t simply be ignored. Professional cleaning can help remove buildup from appropriate exterior surfaces.
- You’re Preparing to Sell Your Home
Clean siding, walkways, patios, windows, and other exterior surfaces can make the property appear better maintained.
- You Can’t Remember the Last Cleaning
If it’s been several years since your home’s exterior was professionally cleaned, it may be time to schedule an inspection or estimate.
Pressure Washing vs. Soft Washing
Not every surface should be cleaned using the same amount of pressure.
Pressure washing is generally suited to harder surfaces such as concrete, sidewalks, patios, and driveways.
Soft washing is commonly used for more delicate exterior surfaces such as siding and roofs.
The goal isn’t simply to use the highest pressure possible. The cleaning method should match the surface being cleaned.
Old Fireman’s Services uses pressure washing and soft washing methods depending on the material and cleaning requirements.
Can Pressure Washing Damage Your Home?
Improper pressure washing can potentially damage certain surfaces.
Using excessive pressure or the wrong technique may cause problems with siding, painted surfaces, seals, wood, or other materials.
That’s why professional exterior cleaning isn’t simply about owning a pressure washer. The operator needs to understand the surface, equipment, cleaning process, and appropriate technique.
For delicate surfaces, a soft-washing approach may be more appropriate than high-pressure cleaning.
How Often Should Different Areas Be Cleaned?
There isn’t one schedule that works for every property, but homeowners can use a general maintenance approach.
House siding: Many homes benefit from professional house washing approximately every 12–24 months, depending on conditions.
Driveways: Driveways may need cleaning more frequently because they experience vehicle traffic, dirt, oil, mud, and weather exposure.
Patios: Patios can accumulate dirt, algae, and organic debris, particularly when surrounded by trees or exposed to moisture.
Decks and fences: Wood and other outdoor materials can develop dirt, algae, and discoloration over time.
Roofs: Roof cleaning requires special care because roofing materials are more delicate than concrete. A suitable soft-washing method may be appropriate depending on the roof material and condition.
What Is the Best Time of Year to Wash a House?
There isn’t necessarily one perfect season for every property.
Spring is popular because homeowners want to remove winter grime and pollen.
Summer can be useful for improving curb appeal and maintaining outdoor living spaces.
Fall cleaning can help remove accumulated dirt, leaves, and organic buildup before winter.
The most important factor is the condition of the property rather than waiting for a particular month.
Why Professional House Washing Can Be Worth It
Professional exterior cleaning can save homeowners time and help ensure that the appropriate cleaning method is used.
A professional service can also help identify areas that need additional attention, such as heavily stained siding, algae growth, dirty concrete, or other exterior buildup.
