Power Washing FAQ

Frequently Asked Questions

How often should I have my home power washed on Long Island?
Most Long Island homes benefit from power washing once or twice a year. If your property is in a shaded area, near trees, or close to the coast, you might need it more often. Salt air, humidity, and seasonal mold growth are harder on homes here than in drier climates. The north side of your house typically needs attention more frequently since it gets less sunlight and stays damp longer. If you’re seeing green streaks, black stains, or that chalky residue on your siding, it’s time.
Not when it’s done right. The problem is when someone cranks the pressure too high or holds the nozzle too close. That’s how you end up with stripped paint, gouged wood, or water forced behind your siding. We use the right pressure for each surface—lower for vinyl and wood, higher for concrete and brick. We also protect your landscaping by pre-wetting plants, covering delicate areas, and using biodegradable cleaning solutions. Professional equipment and experience make the difference between a clean home and a damaged one.
No, you don’t. As long as we have access to a water source and the areas that need cleaning, you’re free to go about your day. We just ask that you close your windows and doors before we start. We’ll text or call when we’re on the way and again when the job’s done. Many of our customers prefer it this way—they leave for work and come home to a clean house without having to stand around and supervise.
Power washing uses high-pressure water to blast away dirt and grime. Soft washing uses low pressure combined with specialized cleaning solutions to break down mold, mildew, and algae. For most siding, roofs, and painted surfaces, soft washing is the smarter choice. It’s gentler on materials and actually kills the organic growth at the root instead of just rinsing it off. We use both methods depending on what we’re cleaning—soft wash for your house and roof, higher pressure for your driveway and walkways.
Yes. Those black streaks are algae called Gloeocapsa Magma, and they’re eating away at your shingles. Left untreated, they shorten your roof’s lifespan and can lead to costly replacements. We use a soft wash method that kills the algae without damaging your shingles or voiding your roof warranty. High-pressure washing a roof is a terrible idea—it strips off the protective granules. Our process is safe, effective, and designed specifically for Long Island’s humid climate where this stuff thrives.
