A renovation or new build in Marin County is a significant investment. Custom millwork, reclaimed hardwood floors, Carrara marble countertops, floor-to-ceiling windows with views of Mount Tamalpais — these are finishes that deserve more than a standard cleaning crew with a mop and a shop vac. Post-construction cleaning is a specialized discipline, and getting it wrong means scratched surfaces, residual construction dust in your HVAC system, and a home that doesn't feel finished even after the contractors leave.
Green Planet Cleaning has provided post-construction cleaning in Marin County for over 15 years. We work with homeowners, general contractors, and custom home builders across the county — from Craftsman renovations in Fairfax to waterfront new builds in Tiburon. This guide covers everything you need to know about the process, what to expect, and how to choose the right service for your project.
Why Post-Construction Cleaning Is Different
Construction dust is not ordinary household dust. It contains fine silica particles from drywall cutting, wood dust from framing and trim work, adhesive residue from flooring installation, paint overspray from spray applications, and caulk residue from sealing work. These particles are smaller than what standard vacuum filters capture — which means a regular cleaning service will simply redistribute them through the air rather than removing them.
Post-construction cleaning also requires surface-specific knowledge. New hardwood floors need pH-neutral cleaners — not the all-purpose sprays that work fine on tile. New marble countertops can be permanently etched by acidic cleaners. Fresh paint can be dulled by abrasive scrubbing. A professional post-construction cleaning service knows which products to use on which surfaces, and which to avoid entirely.
The Three-Phase Post-Construction Cleaning Process
Professional post-construction cleaning is not a single visit — it's a structured three-phase process that works systematically from rough to fine. Each phase builds on the last, and skipping phases means residual dust and debris that will surface over the following weeks.
- Remove all construction debris and packaging
- Sweep and vacuum all surfaces including inside cabinets
- Remove adhesive labels from windows and fixtures
- Wipe down all surfaces to remove bulk dust
- Clean inside HVAC vents and returns
- Remove paint drips from floors and fixtures
- HEPA vacuum all surfaces, walls, and ceilings
- Clean all windows inside and out
- Polish new fixtures and hardware
- Deep clean all bathrooms and kitchen
- Clean inside all cabinets and drawers
- Wipe all baseboards, door frames, and trim
- Final HEPA vacuum of all floors
- Mop all hard floors with surface-appropriate cleaner
- Final window polish and streak check
- Touch-up any missed areas from phases 1–2
- Final walkthrough with homeowner or GC
- Damage documentation report
Marin County Home Surfaces: What Needs Special Attention
Marin County homes have a distinctive mix of materials that require specific cleaning approaches. Craftsman bungalows in Fairfax and Ross often feature original fir floors, painted built-ins, and tile bathrooms. Contemporary homes in Tiburon and Sausalito tend to have large-format porcelain tile, quartz countertops, and floor-to-ceiling glass. Hillside homes in Mill Valley frequently have exposed beam ceilings and redwood siding that requires careful dust management.
"Construction dust settles into every horizontal surface — including the inside of your HVAC system. If you don't clean the vents during post-construction cleaning, you'll be redistributing that dust for months."
Our Marin County post-construction cleaning protocols address each of these surface types specifically. For new hardwood floors, we use Bona Hardwood Floor Cleaner — a pH-neutral formula that cleans without dulling the finish or leaving residue. For marble and stone countertops, we use pH-neutral stone cleaners that won't etch the surface. For new windows, we use a two-step process: first removing adhesive residue with a plastic scraper, then polishing with a streak-free glass cleaner.
Working With Contractors and General Contractors
Many Marin County general contractors schedule post-construction cleaning as the final step before client handoff. We're familiar with construction timelines and can coordinate directly with your GC to schedule around punch-list work and final inspections. We carry $2M general liability insurance and can provide certificates of insurance on request — a requirement for most commercial projects and many high-end residential builds.
For contractors, we offer a streamlined scheduling process: a walkthrough with your site supervisor, a flat-rate quote within 24 hours, and flexible scheduling that works around your project timeline. We've worked with many of Marin County's leading custom home builders and renovation contractors, and we understand the pressure of a client handoff deadline.
