A Word On Dust

Understanding Dust Resettling After Post-Construction Cleaning

While it may seem surprising, fine dust from construction work can continue to settle on surfaces — including countertops, drawers, and cabinets — within just a few hours after cleaning. This is due to factors like air movement and the natural behavior of fine particulate matter.

Fine construction dust can remain airborne for hours to days, especially if air circulation continues through HVAC systems, open windows, or foot traffic. Despite thorough initial cleaning, resettling dust is common in newly built or renovated spaces.

This is supported by the U.S. Environmental Protection Agency (EPA), which notes that fine particulate matter can linger in indoor air and resettle on surfaces. (Source: EPA – Particulate Matter (PM) Pollution)

How Soon Does Dust Settle After Post-Construction?

• Initial Settlement Time: Dust can begin to settle within minutes to hours after being disturbed during construction cleanup.

• Ongoing Settlement: Fine particulate matter can remain airborne and continue to settle for up to 1–2 weeks, especially if the air is not properly filtered or cleaned. 

Can Dust Resettle in Cabinets and Drawers?

Yes — dust can and does settle inside drawers and cabinets, especially if:

• Cabinets were not sealed during construction.

• Doors/drawers were left open during or after the work.

• Fine airborne dust (e.g., from drywall or sawdust) infiltrates through small gaps.

Other Professional Cleaning Services like Maid Brigade and Molly Maid have even recommended cleaning the inside of all cabinets and drawers during post-construction  because dust infiltrates even closed spaces.

Why You May See Dust Again — Even After Cleaning

According to the EPA guidance, fine particulate matter (PM) can remain airborne for extended periods, travel unpredictably through air currents, and settle on surfaces throughout a space. (Source: EPA – Particulate Matter (PM) Pollution)

Even after a thorough  post-construction cleaning, dust may resettle within hours -- often in unexpected  areas such as:

• Inside drawers and cabinets

• Closets and shelves

• On flat surfaces like countertops and windowsills

This is especially true when there’s active air circulation from:

• HVAC systems running

• Open windows or doors

• Ongoing foot traffic

How Long Does This Last?

According to the EPA, fine particulate matter can stay airborne for hours to days, and continues to settle slowly over time. You may notice dust accumulation during the first 1–2 weeks after cleaning.

What We Recommend

☑️  Replace or upgrade your HVAC filter shortly after move-in

☑️  Run your system with strong filtration and good airflow

☑️  Gently wipe down surfaces (including drawers and cabinets) after a few days

☑️  Use microfiber cloths or damp dusters to trap fine particles effectively
