Your new build or renovation is finally done—but your home is coated in dust, drywall mud, and debris. Hiring the wrong cleaning crew means you'll spend weeks scrubbing corners yourself or paying twice to fix it. Knowing what to ask before signing a contract saves you money, headaches, and ensures your finished space actually looks finished.
What Insurance and Licensing Do They Have?
Post-construction cleaning is physically demanding and carries real liability. A reputable company should carry general liability insurance (minimum $1 million) and workers' compensation if they have employees. Ask for proof of current coverage—not a verbal promise. This protects you if someone gets injured on your property or accidentally damages newly installed finishes. Verify their business license with your local city or county authority; it takes five minutes and weeds out fly-by-night operations.
Can They Handle Your Specific Project Type?
A crew that cleans after a kitchen remodel may not be equipped for heavy structural renovation debris. Ask directly: Have they cleaned homes after similar projects? Do they understand the difference between rough cleanup (removing large debris and obvious dust) and final detail cleaning (baseboards, light fixtures, window tracks)? Some companies handle only one phase; others do both. Your project likely needs final cleaning, so confirm they specialize in that stage and won't leave you with a partially cleaned home.
What's Included in Their Quote?
Post-construction cleaning pricing varies wildly based on project scope, square footage, and what "clean" means. A typical final cleaning for a 2,000 sq ft renovation runs $1,500–$4,000, but rough cleanups are cheaper and detail work costs more. Before comparing quotes, ensure they're actually comparable:
- Dust removal: walls, ceiling fans, light fixtures, and HVAC vents
- Floor cleaning: all materials (tile, hardwood, concrete)
- Cabinet and appliance cleaning: inside and outside
- Window and mirror cleaning: interior, exterior, or both?
- Baseboards and trim: wiped down or scrubbed?
- Disposal of construction waste: included or separate fee?
- Timeline: how many days to complete?
A vague quote ("we'll clean your house for $2,500") is a red flag. You need itemized details so you know what you're paying for and can compare fairly.
Do They Handle Hazardous Materials?
If your project involved lead-based paint removal, asbestos abatement, or mold remediation, standard cleaning companies aren't equipped to handle post-cleanup contamination. Ask whether they have certification or training for hazardous material cleanup. If they don't, they shouldn't touch the space until specialized remediation crews certify it's safe. Hiring the wrong team here puts your health at serious risk.
How Will They Protect Your New Finishes?
During cleanup, accidents happen. A careless crew can scratch new hardwood floors, damage fresh paint, or ding newly installed fixtures. Ask how they'll protect surfaces during the cleaning process. Responsible companies use drop cloths, use microfiber mops instead of abrasive materials on finished floors, and avoid harsh chemicals on delicate surfaces. They should also provide a walkthrough with you after cleaning so you can flag any damage immediately rather than discovering it later.
What's Their Guarantee or Follow-Up Policy?
If you spot missed areas after they leave, will they return for free? Most reputable companies offer a 24–48 hour touch-up window at no extra cost. This is standard and shows they stand behind their work. Ask about their warranty in writing before hiring. Some also offer exterior post-construction cleanup if your renovation extended to the yard—confirm whether that's included or a separate service.
Do They Have References or Reviews?
Ask for at least three recent references from residential projects (not commercial ones—different standards). Check Google Reviews, Yelp, or Trustpilot for patterns in feedback. Pay special attention to comments about attention to detail and how the crew handled issues. One bad review isn't disqualifying, but multiple complaints about missed spots or damage should concern you. When comparing providers, sites like Mercoly let you browse trusted post-construction cleaning companies side-by-side with verified reviews and detailed service offerings.
Frequently Asked Questions
Q: How long does final post-construction cleaning typically take? Most homes take 1–3 days depending on project size and complexity; crews are usually done before you move in or occupants return.
Q: Can the same company do rough cleanup and final cleanup? Many can, but confirm they treat each phase properly—rough cleanup is quick and heavy-duty, while final cleaning demands precision and attention to detail that require different equipment and approach.
Q: Should I hire the cleaning crew my contractor recommends? It's worth considering, but compare quotes and reviews independently; contractors may recommend crews for convenience rather than quality, and you're the one paying and living with the results.
