What soft washing actually costs across Raleigh, Durham, Cary and the Triangle — including house exteriors, roofs, fences and commercial buildings.

What drives the price up or down
- Story height — anything above one story adds equipment and safety time
- Access — steep grades, tight side yards, and gated communities take longer
- Growth level — heavy algae or lichen needs longer dwell times and more solution
- Water source — some jobs require a portable water buffer tank
- Landscaping — pre-rinsing large flower beds and shrubs adds prep time
Why soft washing is worth the money in NC's climate
North Carolina's warm, humid summers create ideal conditions for gloeocapsa magma — the algae that causes black streaks on shingles — and for green mildew on shaded siding. Because soft washing uses biodegradable chemistry to kill these organisms at the root, results typically last 4 to 6 times longer than a plain water pressure wash on the same surface. That's the difference between paying for a service every year and paying every three.
How to get an accurate quote
A reputable soft washing company will either walk the property or ask for photos of each elevation, the roof, and any problem areas before quoting. Beware of instant phone quotes — they almost always change on-site once the crew sees the actual scope.
Frequently asked questions
Is soft washing more expensive than pressure washing?
+
Per square foot the labor rate is similar, but soft washing includes cleaning chemistry and longer dwell time so a full-house soft wash typically runs slightly more than a driveway pressure wash. The result also lasts far longer.
How long does a soft wash last in North Carolina?
+
On siding and roofs, expect 12 to 24 months before algae and mildew begin to return, depending on shade, tree cover, and elevation direction.
Do you soft wash in the winter?
+
Yes — as long as temperatures stay above 40°F and there is no freeze risk overnight, cleaning solutions work well through most Triangle winter days.
