Flash Guys Cleaning

Post-Construction Cleaning Services in Los Angeles

Rough, fixture and final cleans for remodels, tenant improvements and new builds, priced by square foot.

Cleaner removing fine construction dust from a newly finished room

Post-construction cleaning in Los Angeles removes the fine dust, debris and residue a build leaves on every surface, so the space can be inspected, handed over or moved into. Schedule the final clean after the last trade finishes and before the walkthrough. On longer projects, a rough clean between phases keeps dust out of the new finishes.

The three phases of construction cleaning

  1. Rough clean

    During the build, once framing and drywall are done. Debris, offcuts, packaging and bulk dust come out, so the trades that follow work on clean floors.

  2. Fixture clean

    After cabinets, fixtures and flooring go in. Stickers, labels, adhesive and the dust that settled on new surfaces come off before anything gets scratched.

  3. Final clean

    Before inspection, handover or move-in. Fine dust from ceiling to baseboard, glass, fixtures, vents and floors, finished with a walkthrough.

Which phases your project needs

Smaller remodels often need only the final clean. New builds and larger tenant improvements benefit from all three, and longer projects can have recurring construction site cleaning while the work is still underway. Tell us where the project stands and we will scope the visit around it.

Dust control on HVAC, vents and new finishes

Drywall and sanding dust travel. They get into the ductwork, ride the air into rooms nobody worked in and settle again after the first pass. That is why post construction cleaning services in Los Angeles should treat the whole space, not just the room that was remodeled: vents, return grilles, ceiling fans and light fixtures are dusted along with walls and trim.

New finishes need care too. Stone, glass and fresh paint scratch or streak when dust is dragged across them, so it comes off with the method each surface allows, not the fastest one. Once the final clean is done, replacing the HVAC filter keeps the system from blowing leftover dust back into the space.

Debris handling and construction cleanup in Los Angeles

Construction cleanup covers the debris left by the finish work: packaging, offcuts, tape, labels and everything swept up during the clean, bagged and removed with the visit. If there is heavier material on site, describe it when you request a quote, so it is either priced in or cleared before the crew arrives.

What the final clean covers

  • Ceilings, walls, trim and baseboards dusted from top to bottom
  • Windows, sills, tracks and glass cleaned of dust and stickers
  • Doors, handles, switches and outlets wiped
  • Cabinet and drawer exteriors wiped, with interiors available as an extra
  • Countertops, sinks and fixtures cleaned and polished
  • Bathrooms cleaned and disinfected, including tile, grout and mirrors
  • Appliance exteriors cleaned
  • Floors vacuumed and mopped, stairs and hallways included
  • Final walkthrough to confirm no dust or residue is left

For contractors and project managers

Post-construction cleaning is the last trade on the schedule, so it has to fit the handover date. Send us the square footage, the phase, the address and the date the space needs to be ready. Crew size is set by the size of the space and the deadline, and the arrival is confirmed by text.

  • Flexible scheduling, including short notice
  • Flat-rate or hourly quotes, priced by square footage and project complexity
  • One-time jobs or recurring visits on active construction sites
  • Trained, background-checked crews, backed by $1M in coverage

If your site requires proof of insurance or a safety orientation before crews come in, mention it when you request the quote.

Where we work across Los Angeles

We clean residential and commercial projects across Los Angeles: Downtown LA and the Arts District, Hollywood and Silver Lake, Koreatown and Mid-Wilshire, the Westside from Santa Monica to Culver City, the San Fernando Valley from Sherman Oaks to Woodland Hills, Pasadena and the San Gabriel Valley, and the South Bay. For lofts, high-rises and tenant improvements downtown, see post-construction cleaning in Downtown Los Angeles.

After the handover

Once the space is occupied, the job changes. A first deep cleaning in Los Angeles catches the dust that resurfaces in the first weeks, and our house cleaning in Los Angeles keeps a newly finished home the way it looked on reveal day.

    It is priced by square foot and adjusted for the phase and the complexity of the project: how much dust, glass and fixtures there are, and how many levels the space has. We quote flat-rate or hourly. Send the square footage and a few photos for an accurate quote.

  • How far in advance should I book a post-construction clean in Los Angeles?

    Yes. Office remodels, retail build-outs and tenant improvements are cleaned in the same three phases, scheduled around the building's access rules.
