For most Bethesda homes, we recommend professional driveway cleaning every 1-2 years. Properties under heavy tree cover (common in Kenwood and Bradley Hills) may benefit from annual cleaning due to accelerated organic growth. If you notice green algae, black staining, or significant discoloration, it's time for a cleaning.

Solvent-based sealers offer a more durable, wet-look finish that typically lasts 2-5 years and provides superior protection against stains and weather. Water-based sealers are lower-VOC, dry faster, and offer a more natural appearance, but typically need reapplication every 1-3 years. We'll help you choose the right option based on your driveway material and aesthetic preferences.

Yes, we use specialized degreasers and hot water pressure washing to remove most oil and automotive fluid stains. Fresh stains come out more easily than old, set-in stains. For stubborn spots, we may apply targeted treatments. We'll assess your specific situation and give you realistic expectations during our quote.

Absolutely. We provide full patio cleaning, sealing, and re-sanding services throughout Chevy Chase and all Bethesda neighborhoods. We work with flagstone, bluestone, travertine, slate, pavers, and concrete patios. Our team will assess your patio's condition and recommend the best sealer type — whether you prefer a natural look or enhanced color.

Polymeric sand uses polymers that harden when activated with water, creating a firm joint that resists weeds and insects. It's excellent for most paver installations. Resin sand uses a resin binder for even greater durability and flexibility — it's more expensive but ideal for high-traffic areas or patios with wider joints. We'll recommend the best option for your specific patio.

When done incorrectly, yes — but we adjust our pressure and technique for each surface type. Flagstone requires lower pressure and wider spray patterns than concrete. We may also use soft washing with specialized cleaners for delicate stone. Our experience with Bethesda's premium flagstone patios means we know exactly how to clean without causing damage.

Yes. We use soft washing techniques that rely on low pressure and specialized cleaning solutions rather than brute force. This safely removes algae, mold, mildew, and dirt from vinyl, stucco, brick, Hardie board, wood, and aluminum siding without causing damage. It's the same method recommended by siding manufacturers.

Green stains are typically algae, while black stains are usually mold or mildew. Bethesda's humid climate and tree coverage create ideal conditions for these organisms. They're not just unsightly — they can actually degrade your siding over time. Our soft wash process kills these organisms at the root, providing longer-lasting results than pressure alone.

Most Bethesda homes benefit from house washing every 2-3 years. Homes with significant shade, north-facing walls, or proximity to trees may need annual cleaning. If you notice visible green algae, black streaking, or general dinginess, it's time for a wash. Regular cleaning also extends the life of your paint and siding.

No — and that's why we use soft washing for roofs, not pressure washing. High pressure can damage shingles, void warranties, and cause leaks. Our soft wash method uses low pressure with specialized cleaning solutions to safely remove black streaks, moss, lichen, and algae without harming your roof.

Those black streaks are caused by Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. It's extremely common in humid climates like Bethesda's. Beyond being unsightly, this algae can actually shorten your roof's lifespan by retaining moisture and causing premature deterioration.

Yes, but it requires proper technique. Composite and Trex decking need lower pressure and specific cleaning solutions to avoid damage. We follow manufacturer guidelines for each decking type. Many Bethesda homeowners with composite decks are surprised how much cleaner their deck looks after professional cleaning — these materials still accumulate grime despite being "low maintenance."

Absolutely. Professional cleaning is essential before staining or sealing a wood deck. It removes dirt, mildew, and weathered wood fibers, allowing the stain to penetrate properly and adhere evenly. Staining over a dirty deck leads to poor results and premature peeling. We can clean your deck and leave it ready for your stainer or refer you to a trusted contractor.

Yes, we provide commercial pressure washing services throughout Bethesda, including storefronts, office buildings, and restaurants in the Bethesda Row area and along Wisconsin Avenue. We work around your business hours to minimize disruption and can schedule early morning, evening, or weekend service as needed.

For restaurants and food service businesses, we recommend monthly dumpster pad cleaning to control odors and maintain sanitary conditions. Retail and office buildings can typically go 2-4 months between cleanings. Regular cleaning prevents grease buildup, reduces pest attraction, and helps you stay compliant with health codes.

Yes! Many Bethesda businesses find that regular maintenance contracts provide the best value and ensure their property always looks its best. We offer monthly, quarterly, and annual maintenance plans customized to your needs. Contact us to discuss a schedule that works for your business.
