Beyond the Broom: Construction Dust Needs Pros

Fine dust behaves differently than everyday dirt—it stays airborne, infiltrates HVAC, and re-settles for days. General cleaning can re-aerosolize it. Our workflow, equipment, and sequencing are built to capture, contain, and finish dust for good.

Air Scrubbers (CFM 275–700)

Captures airborne particulates while crews work—reduces re-settling and protects finishes.

  • True HEPA capture (99.97% @ 0.3µm)
  • Ductable for negative-air containment
  • Variable speed for occupied or tight spaces

Post-Construction HEPA Vacuums

Sealed HEPA Vacuums

Prevents dust blow-through; safe for floors, millwork, and high-end finishes.

  • Sealed bodies & multi-stage filtration
  • Soft-brush tools for non-marring detailing
  • Edging & vent vacuuming to stop recirculation

Why general cleaning isn’t enough

General Cleaning
  • Re-aerosolizes fine dust
  • No air handling / negative pressure
  • Non-HEPA vacuums leak particles
Construction-Safe Method
  • Air scrub + sealed HEPA extraction
  • Ductable negative-air containment
  • Sequenced, top-down final detailing

* HEPA filters are rated to capture 99.97% of 0.3µm particles when properly fitted and maintained.

Our Method

The Long Island Maids Two-Stage Dust Mitigation System

We don’t just make it look clean—we finish dust. Our two-stage sequence captures airborne and settled dust, lets fines fall during a short settling window, then performs a meticulous, top-to-bottom final.

Intensive Rough Clean & Airborne Dust Mitigation

Control the air, then attack surfaces. Prevent re-aerosolization from the start.

HEPA 700 Air Scrubbers Sealed HEPA Vacuums
  • Ductable air scrubbers run during work to capture fines (0.3µm @ 99.97%).
  • Top-down dusting of vents, trims, fixtures; sealed HEPA edging.
  • Neutral-pH damp bind on hard surfaces; no harsh chemicals on new finishes.
  • HVAC grills/returns vacuumed to reduce recirculation.

The Critical Settling Window (3–5 Days)

Airborne micro-dust naturally re-settles. Waiting ensures Stage 2 removes what Stage 1 dislodged.

  • Minimize traffic and keep windows closed where possible.
  • Optional: leave an air scrubber running in long-dust environments.
  • Schedule Stage 2 immediately after—avoid new trades between stages.

Top-to-Bottom Deep Clean & Final Polish

Detailing pass that removes settled fines and delivers a true “move-in ready” finish.

Microfiber → Damp → Tack Sealed HEPA Edging Finish-Safe Products
  • High-to-low sequence on all millwork, ledges, fixtures, and hardware.
  • Glass, mirrors, and surfaces polished streak-free; floors vacuumed & damp mopped.
  • Punch-list walk-through with PM/owner; immediate touch-ups included.

Add-ons on request: Interior appliances, interior windows, and cabinet interiors can be included for post-construction projects when specified in the proposal. (These are optional add-ons by default.)

FAQs

Everything You Need to Know About the Final Clean

Clear, specific answers for builders, project managers, and homeowners across Long Island.

Q: Which areas of Long Island do Long Island Maids' post-construction cleaning crews service?

A: We proudly serve the entire length of Long Island, specializing in post-construction jobs across Nassau County (from Oyster Bay to Garden City) and all of Suffolk County (from Islip to Riverhead). We also offer specialized, high-end services for projects in The Hamptons.

Q: How soon can you schedule a final clean, especially for projects in West Hampton or Huntington?

A: We recommend booking as soon as the project rough-in is complete. We understand construction timelines shift, which is why we offer flexible scheduling and can deploy crews to meet tight deadlines in areas like Huntington and West Hampton with minimal notice dependent on our schedule

Q: Why is your Two-Stage Dust Mitigation System necessary for an effective clean?

A: Fine drywall dust and silica are microscopic and continue to settle for days. Our Two-Stage System, which includes an initial deep clean followed by a final polish 3-5 days later, is essential. We run DryEaz 700 Air Scrubbers across both visits to ensure we capture all settled and airborne dust for superior air quality.

Q: Do you use HEPA-filtered equipment for all post-remodel cleaning projects?

A: Absolutely. We use professional-grade, HEPA-filtered vacuums and our DryEaz Air Scrubbers on every job. This is non-negotiable for post-remodel cleaning as it prevents the fine construction dust from being recirculated back into the air and settling on finished surfaces.

Q: How much does post-construction cleaning cost and how is your pricing structured?

A: Due to the highly variable nature of construction dust and project complexity, we structure our pricing based on man-hours to ensure you only pay for the work required. Our rate is [Your Specific Hourly Rate] per cleaner, with a 4-man-hour minimum per visit. The total investment for your Long Island project will be determined by project size, the Two-Stage System required, and the efficiency of our specialized crew. We provide a clear, written proposal with an estimated time range after evaluating your project.

Q: What size projects can Long Island Maids handle, from small renovations to new construction?

A: We scale our teams for projects of all sizes across Long Island, from single-room residential renovations in Massapequa to full new construction cleaning of custom homes and multi-unit buildings.

Q: Are you fully insured and bonded to work on construction sites in Nassau and Suffolk County?

A: Absolutely. We maintain comprehensive General Liability which is required for all professional service providers on Long Island construction sites.

Q: How do you guarantee the removal of fine construction dust and improve indoor air quality?

A: We specialize in the removal of the microscopic dust that traditional cleaning misses. Our proprietary Two-Stage Dust Mitigation System uses industrial-grade, CRI-Certified HEPA-filtered vacuums and HEPA Air Scrubbers to capture particles down to 0.3 microns. This process not only cleans surfaces but actively purifies the air, ensuring your newly constructed or post-renovation space is truly move-in ready and healthy.

Q: Do your post-construction services include debris or waste removal?

A: Yes, but we clarify the scope. Our service includes the removal and bagging of all light construction debris, such as tape, plastic, drywall scraps, nails, and packaging, as part of the Rough Clean phase. We do not typically haul away heavy or large-volume debris (like sheetrock piles or lumber) that require a dumpster or roll-off container, as this is usually the contractor's responsibility.

Q: Are you trained to clean specialty and luxury finishes like marble, custom millwork, and high-end flooring?

A: Yes. We understand that many Long Island and Hamptons projects involve expensive, sensitive materials. Our teams are rigorously trained in material-specific cleaning protocols. We use non-abrasive, pH-neutral, and eco-safe products to remove paint splatter, adhesives, and dust from natural stone (like marble and quartz), delicate custom millwork, and newly finished hardwood floors without causing any damage, preserving the integrity of your investment.

Do you offer after-hours or weekend crews?

Yes — we can schedule night or weekend work with advance notice to align with inspections, walk-throughs, and hand-offs anywhere on Long Island.

What site conditions do you require before cleaning?

We require running water, electricity, safe access (keys/lockbox), and clear pathways. For multi-floor buildings, elevator access may be required. We’ll confirm these during your proposal or walk-through.
