Health-First Sanitization: Meeting the NIH-Level Standard
With the medical community in our backyard, we prioritize hygiene over just “appearances”:
- HEPA H13 Filtration: Our vacuums capture 99.97% of particulates down to 0.3 microns—essential for asthma and allergy sufferers.
- Cross-Contamination Prevention: We use a color-coded microfiber system to ensure tools used in bathrooms never touch your kitchen surfaces.
- Low-VOC Chemistry: We use botanical, eco-friendly disinfectants that are safe for pets, children, and the environment.
Asset Preservation: Care for Historic Millwork & Luxury Finishes
Bethesda’s high-value homes require more than a “standard” clean:
- Natural Stone: pH-neutral cleaners for marble, quartzite, and granite to prevent etching.
- Custom Cabinetry: Non-abrasive methods for matte, lacquer, and high-gloss finishes.
- High-End Hardware: Careful polishing of “jewelry” fixtures like brushed gold or matte black.

Safe, reliable service for those commuting via the Red Line or the Beltway:
