The Short Answer
Most exterior cleaning in Northern Virginia runs about $0.10–$0.50 per square foot — a typical house washing lands around $250–$700, roof cleaning $450–$1,200, and driveways $150–$450, depending on size, height, and buildup. Bundling multiple surfaces on one visit lowers the per-service cost meaningfully, because the setup is shared. Every job starts with a free walkthrough and ends with a written, line-item quote in 24–48 hours — no pressure, no surprises.

Exterior Cleaning & Pressure Washing FAQs
How much does pressure washing cost in Northern Virginia?
Most exterior cleaning runs about $0.10–$0.50 per square foot, so a typical house washing lands around $250–$700 depending on size, height, and buildup. Bundling house, roof, driveway, and gutters lowers the per-service cost. Every quote is written and line-item, delivered within 24–48 hours of your free walkthrough.
How often should I have my house washed?
At least once a year is ideal, typically spring through fall before freezing temperatures. In Northern Virginia, heavy pollen, humidity, and shade make annual soft-washing the sweet spot for stopping algae, mildew, and black streaks before they set in.
What is the difference between soft washing and pressure washing?
Soft washing uses low pressure plus specialized cleaning solutions to safely clean delicate surfaces like siding and roofs. Pressure washing uses higher pressure for hard surfaces like concrete, pavers, and brick. We match the method to the surface so everything gets clean without damage.
Will pressure washing damage my roof or siding?
Not when it is done right. We soft-wash roofs and siding — low pressure, correct chemistry — so we clean without cracking shingles, forcing water behind siding, or voiding manufacturer warranties. High pressure is reserved for surfaces that can take it.
Does exterior cleaning remove mold, algae, and black streaks?
Yes. Our soft-wash solutions kill algae, mold, and mildew at the root rather than just rinsing the surface, so the streaks and green growth do not come right back — and your home stays cleaner, longer.
Is professional pressure washing worth it?
Yes. The right pressure and chemistry for each surface avoids the damage and warranty issues that come with DIY or one-size-fits-all crews — and bundling multiple services with one licensed, insured team saves money versus renting equipment or hiring separately.
How long does exterior cleaning take, and when is the best time?
Most jobs are completed in a half day to a full day depending on scope. The best windows are spring (a pollen reset) and fall (pre-holiday, post-leaf) — but we clean year-round whenever temperatures allow.
