Local brick cleaning for Rockville, MD
Humid summers in Maryland grow green algae and black mildew on the shaded sides of homes, especially on vinyl and painted wood. A soft wash kills the growth rather than just knocking it off, so the siding stays clean longer.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.

Brick Cleaning: frequently asked questions
How much does brick cleaning cost in Rockville, MD?
Brick Cleaning typically costs $250-$700 for a typical brick home front or chimney, and usually takes 2-4 hours. The exact price depends on the size and condition, and you get it before any work starts. Call (555) 010-0000 for a free quote.
Do you use high pressure for brick cleaning?
Brick Cleaning is done with low-pressure wash and masonry cleaners. Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.
Is brick cleaning safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule brick cleaning?
Every 2-3 years. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
