Post-Construction Cleaning Experts

Transforming an active construction site into a move-in-ready architectural masterpiece requires intensive, multi-phase cleaning expertise. At Bertha's Cleaning and Janitorial, our post-construction cleaning crews eliminate heavy drywall dust, saw residue, paint splatters, and packaging debris from newly built luxury homes and commercial renovations. Construction dust settles in unseen HVAC vents, inside custom cabinetry, along window tracks, and on delicate light fixtures. Our technicians utilize industrial HEPA filtration vacuums, specialized adhesive removers, and microfiber polishing cloths to reveal the true beauty of new hardwoods, custom tilework, and designer countertops without scratching fresh finishes.



General contractors and custom builders across Napa, Sonoma, and Solano Counties count on us because we respect critical inspection deadlines and architectural budgets. Founder Bertha Vargas works hand-in-hand with site superintendents, providing flexible rough, final, and touch-up cleaning phases that align with contractor timelines. We are fully insured, safety-certified, and equipped with hard hats, safety glasses, and commercial ladders. We never rush over stubborn window stickers, grouting haze, or sawdust hidden in cabinet hinges. Our reliable team delivers immaculate, turnkey turnovers that impress discerning homeowners and pass stringent building inspections without delay.

Our post-construction cleaning execution begins with a thorough site survey to identify delicate materials, scope of debris, and immediate turnover schedules. Phase one focuses on rough clearing, discarding trash, and extracting airborne construction dust with heavy-duty HEPA vacuums. Phase two delivers detailed scrubbing: removing paint flecks, washing interior window glass, scraping tape residue, cleaning recessed light fixtures, and detailing bathroom tiles. Phase three provides a white-glove final wipe-down of all baseboards, switch plates, and door casings. We perform a joint walk-through with the project manager to guarantee flawless, dust-free move-in presentation.
