Questions to Ask Before Hiring a Post-Construction Cleaning Company in Baltimore

When your build or renovation wraps up, dusty floors, paint spots, and leftover debris still haunt your site. You need a cleaning crew that knows how to clean up construction mess, not just vacuum and mop. If you want to hire post construction cleaners in Baltimore, you’ll need more than a quote. Ask smart questions. Here are the key questions to ask before hiring a post-construction cleaning company in Baltimore.

What’s your experience with post-construction cleaning, especially in Baltimore?

You want a company that has real experience, not just regular house cleaning. Ask:

• “How many post construction jobs have you done in Baltimore or the Mid-Atlantic area?”
• “Can you show me photos or references from similar projects?”
• “Have you worked in historic homes, high-rise buildings, or commercial renovations here?”

A crew experienced in post construction cleaning Baltimore will know how to handle sticky drywall dust, concrete residue, paint splatter, and local codes (Baltimore storms, city permits, etc.).

Are you licensed, insured, and bonded?

Construction sites carry risks: broken glass, sharp nails, heavy tools. You must protect yourself.

• “Do you carry general liability insurance? Can I see proof?”
• “Are your workers covered by workers’ compensation?”
• “Do you offer bonding or damage protection in case something gets broken or scratched?”

If a cleaner refuses or can’t show valid insurance, walk away.

What’s included in your scope of work? What’s extra?

Not all crews agree on what “post-construction cleaning” means. Get that in writing.

Ask:

• “Will you remove debris, sweep, vacuum, and deep-wipe all surfaces?”
• “Do you clean ceilings, duct vents, air grilles, and light fixtures?”
• “Will you polish glass, windows, mirrors, and clean frames?”
• “Do you handle adhesive, paint drips, or caulk residue?”
• “Are blinds, baseboards, tile grout, and hardware included?”

Get a detailed checklist. That way you won’t be hit with surprise fees later.

What equipment, tools, and products will you use?

The right gear makes a big difference.

• “Do you use HEPA vacuums to trap fine dust?”
• “What chemicals or cleaners do you use? Are they safe for new surfaces (wood, stone, glass)?”
• “Will you bring your own tools like ladders, scaffolding, squeegees, buffers?”
• “Do you have power-washing or steam equipment if needed?”

If they show up with standard mops and a bucket, you’ll regret not asking.

How will you manage timing, scheduling, and access?

Construction schedules shift. You need the cleaners to sync with your site.

• “When can you start? How many days or hours will it take?”
• “Can you work nights or weekends if needed?”
• “What if the site isn’t fully ready (contractors still finishing)? Do you have flexibility?”
• “How much lead time do you need for scheduling in Baltimore?”

You don’t want the cleaning crew blocking trades or overlapping with other work.

How will you handle safety, compliance, and site rules?

Construction sites have rules. The cleaning crew must follow.

• “Do your crews follow OSHA standards and site safety protocols?”
• “Are they trained in hazard recognition (fresh nails, exposed wiring, etc.)?”
• “Do you carry and use personal protective equipment (PPE), gloves, goggles, masks?”
• “Can you sign site safety agreements, provide safety documentation, or clear access per site rules?”

If they can’t commit to safe, regulated work, you’ll expose yourself to risk.

Who will supervise? What about quality control and inspections?

You don’t want random workers without oversight.

Ask:

• “Will there be a foreman or supervisor assigned to my project?”
• “Do you conduct walk-throughs with me after cleaning?”
• “What’s your process if I find an area you missed?”
• “Do you stand behind your work with a guarantee or redo policy?”

Accountability matters. You want someone to fix errors without argument.

8. What are your payment terms, pricing, and estimates?

Money talks. Be clear up front.

• “Do you give a detailed written estimate or contract?”
• “Is the price per square foot, hourly, or fixed for the job?”
• “Are there extra charges for blinds, windows, or heavy adhesive removal?”
• “When is payment due; deposit, day of service, final walk-through?”
• “Do you require holdbacks or retainers until final approval?”

A vague quote is usually a trap.

Do you offer references, testimonials, or past client contacts in Baltimore?

Good cleaners will give you names or case studies.

• “Can you share contact info for clients who had post construction cleaning?”
• “Do you have reviews specific to Baltimore jobs?”
• “Do you have before and after photos?”

Talk to those clients. Ask if the cleaner delivered.

10. How do you dispose of waste, dust, and hazardous materials?

Cleaning up is not just surface work; disposal is part of the job.

• “Do you remove and haul away construction debris, packaging, scrap wood?”
• “How do you dispose of chemicals, paint cans, solvents?”
• “Do you recycle when possible?”
• “Will you leave the site broom clean with all waste removed?”

You don’t want leftover mess or regulatory fines.

What happens if there is damage or breakage during cleaning?

Even the cleanest team can slip.

• “Do you carry damage protection or guarantee repair/replacement?”
• “What is your policy if you break a window, chip a surface, or scuff marble?”
• “How do you document existing damage before you start?”

Take pictures with the company before work begins. Use that as a baseline.

Can you accommodate special or delicate materials?

Some surfaces can’t take harsh chemicals so make sure to ask these vital questions too.

• “Have you cleaned marble, terrazzo, hardwood, glass curtain walls?”
• “Do you adjust your methods per surface sensitivity?”
• “Do you test on a small hidden area first?”

You don’t want your new materials ruined by overzealous cleaning.
