Post-Construction Cleaning: What It Includes and Why It Matters

After the last contractor leaves, the job isn’t over — it’s actually just changed owners. The final step of any build or renovation is the one most people underestimate: the cleanup. Construction dust is not normal dust, and a standard house cleaning will not remove it.

Why construction dust is different

Drywall dust is fine, powdery and relentless. It settles into vents, blinds, cabinet hinges and every horizontal surface — and it keeps settling for weeks. Wiping a counter with a regular cloth just pushes it around. It also clogs vacuum filters and, in a renovation, can contain silica or paint residue you don’t want to spread.

What a post-construction clean includes

• Debris removal — leftover materials, packaging, trash
• Fine dust removal — walls, ceilings, trim, vents
• Interior windows and tracks — the dust magnets of any job site
• Cabinets and drawers — inside and out, free of grit and filings
• Fixtures and appliances — lights, faucets, new appliances
• Floor care — repeated passes until floors stop releasing dust

When to book it

• After substantial renovations — kitchens, bathrooms, additions, basement finishes
• New builds before move-in — builders rarely include this in scope
• Before listing or photographing a home — nothing photographs worse than dusty trim
• After painting and drywall work — the dustiest of all projects

What it costs

Post-construction pricing depends on square footage and how much debris is involved; in New Hampshire, most residential post-construction cleans run $400 and up, with larger projects scaling from there. It’s not the cheapest clean — it’s the one that saves your furniture, your lungs and your timeline.

Booking tips

• Wait until all trades have finished. One leak repair after cleaning means starting over.
• Ask about vent and HVAC cleaning separately — some dust has already traveled.
• If the space was also a residence (renovating a lived-in home), say so: the clean includes occupied-home precautions.
