A homeowner in the eastern suburbs called us a few years back, not to book a cleaning, but to ask what could be done about a honed marble island that had gone cloudy and dull in a band about three feet wide. Nothing dramatic had happened. A cleaning crew had simply been wiping it down every week with an all-purpose spray off the grocery shelf. The spray was acidic. Marble is calcium carbonate. Week after week, the surface etched a little more until the damage was visible from across the room. Nobody was careless. Nobody was dishonest. The crew just didn't know, and no one had asked them.
That's the gap most homeowners don't see until it's expensive. A standard house-cleaning company can be perfectly good at what it does and still be the wrong fit for a high-end home. After thirty-five years working in properties from Greensburg to Pittsburgh, here's how we'd tell you to evaluate anyone you're considering handing a key to.
A standard cleaning company isn't automatically qualified for a high-end home
The difference isn't effort — it's exposure. In a high-end home, the surfaces themselves are the risk:
- Natural stone. Marble, travertine, limestone, and honed granite all react to acidic and alkaline products. Etching is physical damage, not a stain, and it doesn't wipe off.
- Fine finishes and millwork. Hand-rubbed lacquer, oiled hardwood, custom cabinetry, and specialty paint finishes can be burnished, streaked, or stripped by the wrong pad or product.
- Art and framed pieces. Aerosolized cleaner drifts. Glass cleaner sprayed near a frame can wick behind the glass and reach the piece itself.
- Heirlooms and collections. Silver, brass, porcelain, and antique wood each want a different approach, and the wrong one is permanent.
- Integrated technology. Panel systems, in-wall speakers, smart glass, and display screens don't tolerate saturated cloths or ammonia.
- Specialty fixtures. Unlacquered brass, living finishes, natural-fiber rugs, and hand-glazed tile all age on purpose. They should not be "corrected."
None of this means a crew has to be exotic. It means they need to recognize what they're standing in front of and know when to stop and ask.
Insurance and bonding are non-negotiable
This is the first question, and the answer should be immediate and specific. A company that has to think about it is telling you something.
- General liability insurance covers accidental damage to your property.
- Bonding protects you against theft by an employee working in your home.
- Workers' compensation matters because if someone is injured in your house and isn't covered, the exposure can land on you.
Ask for a certificate of insurance, not a verbal assurance. Any established company can produce one the same day. Also ask whether the people in your home are W-2 employees or subcontractors — subcontracted labor often sits outside a company's coverage, and you should know either way before anyone starts.
Discretion and a consistent crew
In a luxury home, the crew sees everything: schedules, guests, valuables, the layout of the house, the alarm routine. That's why consistency matters as much as skill.
- Same faces every visit. You should be able to name the people who clean your home. Rotating strangers through a private residence is a security posture, not a staffing detail.
- Background-checked staff. Ask what the screening process is and whether it's repeated.
- A written confidentiality expectation. Professional companies train on it; some formalize it. Either way, the answer shouldn't be a shrug.
- Key and code handling. Ask how keys, fobs, and alarm codes are stored, who has access, and what happens the day an employee leaves.
- Quiet presence. Good crews in occupied homes work around the household, not through it.
The technique questions worth asking
These separate a company that has done this work from one that intends to. Ask them plainly, and listen for specifics rather than reassurance.
- "How do you clean natural stone?" You want to hear pH-neutral, stone-safe products — and no vinegar, no citrus, no generic all-purpose spray on marble or limestone.
- "What do you use near artwork and framed pieces?" The right answer involves spraying the cloth rather than the surface, dry dusting with soft microfiber, and leaving conservation-grade pieces alone unless instructed.
- "How do you handle electronics and display screens?" Dry or barely damp microfiber, never a wet cloth, never ammonia-based glass cleaner.
- "How do your crews learn a home's fragile surfaces?" Look for a documented walk-through, notes on the account, and a named point of contact when something is unclear.
- "What's your process when something breaks?" An honest company tells you it happens, explains how they report it immediately, and describes how the claim works.
- "Do you color-code or separate cloths and tools?" It sounds small. It's the difference between a bathroom cloth and a kitchen counter.
- "How do you handle hardwood and specialty floors?" Ask about moisture control and pad selection. Over-wetting a wood floor is one of the most common and most costly mistakes in a fine home.
Red flags
Some of these are dealbreakers on their own. Together, they're a pattern.
- No on-site walk-through. Anyone who quotes a large home by phone or from a photo hasn't seen the surfaces they're responsible for.
- Vague answers on insurance. "We're covered" without a certificate isn't an answer.
- High crew turnover. If they can't tell you how long their team members have been with them, expect a new person in your house every month.
- A price that doesn't match the scope. An unusually low bid on a large home usually means the scope is thinner than you think or the labor isn't properly covered.
- No written scope. If nobody wrote down what's included, disagreements are inevitable.
- Pressure to sign immediately. Reputable companies expect you to compare.
- One product for everything. A single all-purpose spray for stone, wood, glass, and stainless is the marble story above, waiting to happen.
What a proper first visit should look like
The estimate is your best preview of how a company works. A serious one walks your home before it quotes.
- A room-by-room walk-through with someone empowered to make decisions, not just a salesperson.
- Questions about your surfaces — where the stone is, which finishes are delicate, which pieces are off-limits, which rooms matter most.
- Notes on your household — pets, alarm systems, access, laundry preferences, which days work, which don't.
- A written scope listing exactly what's included per visit and what's handled on a rotating or seasonal basis.
- A clear crew plan — how many people, roughly how long, and who they'll be.
- A straight answer on the number, with no obligation attached to it.
If a company does all of that before it asks for your business, that's usually how it will behave once it has it.
Trust is the actual service
Cleaning a high-end home well is a technical skill. Being trusted inside one is something else. The families we've worked with the longest didn't stay because of a checklist — they stayed because the same people show up, nothing gets moved that shouldn't, and the house feels right when they walk back in.
Mindy's Luxury Home & Estate Cleaning serves the Greensburg-to-Pittsburgh corridor with the same standard we've held for thirty-five years: insured and bonded, consistent crews, and white-glove care for the surfaces that can't be replaced. Every estimate starts with an on-site walk-through, it's free, and there's no obligation.
