A Cleaner Home Starts With a Safe, Professional House Wash

Your home is constantly exposed to the elements—sun, rain, dirt, mold, and pollen. Over time, your siding loses its color, collects stains, and starts to look dull or even damaged.
The good news? You don’t need a new paint job or major repairs—just a smart, safe cleaning.
 
At Exterior Prowash, we help homeowners across Chapel Hill and surrounding areas restore their home’s beauty with expert house washing that’s gentle on surfaces and tough on grime.

What Exactly Is House Washing?

Mold, mildew, and dirt quietly build up on your home’s exterior, creating stains and even structural issues. Pressure from weather, moisture, and UV rays weakens siding and makes your home look older than it is. Our house washing service uses a low-pressure soft wash to remove algae, mold, spider webs, and grime—all without damaging your surfaces.

What Surfaces Do We Clean?

Brick

We clean brick safely, lifting mold and discoloration while preserving mortar and natural texture.

Limestone

Limestone is soft and porous. Our gentle, soft wash removes algae and grime without erosion or pitting.

Vinyl

Vinyl siding can warp with high pressure. We use a low-pressure wash to clean away buildup without causing cracks or streaks.

A once-a-year house wash can go a long way. Here’s why homeowners in Chapel Hill call us regularly:

Soft Washing vs. Pressure Washing: What’s the Difference?

Pressure Washing 

Uses high pressure to blast off dirt—great for concrete but risky on siding or shingles.

Soft Washing

Combines gentle pressure with biodegradable cleaners to remove mold, mildew, and dirt without stripping paint or causing cracks.

Not sure if it’s time? Look for these common signs around your house:

  • Green or black patches on siding
  • Dusty or faded color, especially under windows
  • Spider webs and wasp nests building up around eaves and porch lights

If you’ve noticed any of these, it’s time to give your home the fresh start

it deserves.
