After renovations, expansions, or new builds, your home is covered in dust, debris, and construction residue that regular cleaning can't handle. You need a specialized post-construction cleaning service that knows how to safely remove hazardous materials, restore surfaces, and actually make the space livable again. Here's what separates competent providers from ones that'll leave you disappointed.
Verify They're Insured and Bonded
This is non-negotiable. Post-construction cleaning involves potential exposure to asbestos, lead paint dust, silica, and sharp debris. A legitimate service carries general liability insurance (minimum $1 million) and workers' compensation coverage. Ask for proof before scheduling anything—not just verbal confirmation. If a provider brushes this off or can't produce documentation, walk away immediately.
Check Their Experience With Your Specific Project Type
A crew that handled a kitchen remodel may not be equipped for a full foundation-to-roof new build. Ask how many projects similar to yours they've completed in the last year. Request references from recent clients in your area, and actually call them. Specifically ask:
- How long did the actual cleaning take?
- Were they thorough with hidden areas (inside cabinets, under stairs, window tracks)?
- Did they respect your timeline and show up as scheduled?
Understand Their Equipment and Methods
Professional post-construction teams should use:
- HEPA-filter vacuums (standard contractor-grade vacuums recirculate fine dust)
- Pressure washers for exterior debris and concrete cleanup
- Specialized degreasers for construction residue
- Dust containment systems if working near occupied areas
Ask what equipment they bring and what stays at their facility. Cheaper operators often use inadequate tools, meaning dust and allergens settle back onto surfaces within days.
Get a Detailed Written Quote
A legitimate estimate should itemize what's included. Don't accept vague pricing like "$2,500 for the whole house." Instead, expect breakdowns like:
- Rough cleaning (post-framing, pre-drywall): typically $0.15–$0.30 per square foot
- Final cleaning (move-in ready): typically $0.25–$0.50 per square foot
- Specialized services (window washing, appliance cleanup, disposal fees): listed separately
Timeline matters too. Most post-construction teams need 1–3 days for a 3,000-square-foot home, depending on the scope. Get this in writing so there's no surprise extension fees.
Ask About Waste Disposal
Construction debris isn't trash—it often requires special handling. Confirm the provider covers disposal costs or clearly discloses them upfront. Responsible companies either haul debris themselves or use licensed disposal services, not dump it in regular waste streams. This affects your liability if something ends up in the wrong place.
Request a Pre-Cleaning Walkthrough
Many post-construction clients have different expectations about what "clean" means. Does final cleaning include inside the oven? Behind baseboards? Inside light fixtures? A thorough provider schedules a brief site visit (in person or virtual) to discuss priorities and identify problem areas before charging you. This prevents expensive do-overs.
Check for Green Certifications if You Care
If you're health-conscious or environmentally minded, ask whether they use eco-friendly degreasers and dust suppressants. Some providers are IICRC (Institute of Inspection, Cleaning and Restoration Certification) certified, which indicates formal training in contamination handling. It's not required for basic cleaning, but it's a mark of professionalism.
Compare Multiple Quotes
Get at least three estimates. Watch out for outliers—a quote 50% lower than competitors often means corner-cutting, while one significantly higher might reflect premium service you don't need. The mid-range option from a well-reviewed provider is usually your safest bet.
When you're ready to hire, platforms like Mercoly let you compare multiple post-construction cleaning providers, read verified reviews, and request quotes in one place—saving time and reducing the risk of hiring an underqualified team.
Frequently Asked Questions
Q: How long after construction can I move in? After final cleaning is complete, you can typically move in the same day, though you might want to wait until any chemical smells from degreasers fully dissipate (usually 24 hours).
Q: Will post-construction cleaning remove all dust and allergens? A professional HEPA-equipped service removes 99.97% of particles, but some trace dust may resettle over 1–2 weeks; running air purifiers afterward helps significantly.
Q: What if they miss spots during final cleaning? Reputable companies offer a 24–48 hour touchup window included in their price—get this commitment in writing.
