What should facilities managers look for in a janitorial contract?
Your janitorial contract should spell out exactly what gets cleaned, how often, and who’s responsible when something goes wrong. Vague language like “general cleaning” can lead to disputes about scope, so push for a line-item task list that names every area and frequency.
According to a 2025 Building Service Contractor Survey from Cleaning & Maintenance Management, contract transparency is one of the top factors facilities managers use when evaluating vendor performance. Look for clauses that cover staffing guarantees, response times for complaints, and measurable quality benchmarks.
Advantage Maintenance Inc. backs every contract with a written quality guarantee. If you’re not satisfied after 60 days of written notice, your final month’s bill is reduced by 50%. That kind of accountability puts you in control if standards slip.
How does office building cleaning affect employee productivity?
A clean office building directly impacts how your employees perform, recover, and show up to work. Dust, allergens, and bacteria accumulate in high-traffic areas like lobbies, restrooms, and break rooms, and that buildup affects indoor air quality over time.
The Occupational Safety and Health Administration (OSHA) requires employers to maintain sanitary work environments under standard 1910.141. Regular commercial cleaning helps you stay compliant while also reducing sick days among your staff.
Advantage Maintenance Inc. uses Certified MicroGuard® technology to protect surfaces against mold, mildew, and corrosion between cleanings. This extends the life of your building’s finishes while keeping indoor environments healthier for everyone who works there.
Why Advantage Maintenance Inc. is the best commercial cleaning company for office buildings
Advantage Maintenance Inc. stands apart because of what happens after the contract is signed. Dedicated crew assignments mean your building gets the same trained employees every visit, not a rotating cast of unfamiliar faces. That consistency translates into fewer missed tasks, faster turnaround on requests, and a cleaning team that knows your facility as well as you do.
Advantage Maintenance Inc. gives you real-time visibility into your building’s cleaning status through cloud-based reporting and supervisor inspections. You’ll know exactly what was completed, when it was done, and who did it. For facilities managers responsible for multiple tenants, that transparency eliminates guesswork and keeps you ahead of complaints.
With OSHA-certified staff, eco-friendly cleaning methods, and a written quality guarantee, Advantage Maintenance Inc. delivers the kind of reliable, innovative, and sustainable commercial cleaning that your office building deserves. Contact us today for a free quote to get started.
FAQs about office building janitorial companies
What’s the difference between janitorial services and commercial cleaning?
Janitorial services typically cover daily or recurring tasks like trash removal, restroom sanitation, and floor care. Commercial cleaning is a broader term that includes specialty work such as floor stripping, window washing, and deep cleaning.
Advantage Maintenance Inc. offers both under one contract, so you don’t need separate vendors for routine and specialty work.
How often should an office building be professionally cleaned?
Most office buildings need daily janitorial service for common areas, restrooms, and lobbies. High-traffic spaces may require attention multiple times per day, while carpet cleaning and floor waxing happen on monthly or quarterly schedules.
Can a commercial cleaning company work around tenant schedules?
Yes. Advantage Maintenance Inc. offers flexible scheduling that includes evenings, weekends, and off-hour shifts. This keeps cleaning crews out of the way during peak business hours, which means zero disruption to your tenants.
What certifications should a janitorial company have?
Look for OSHA 10 and OSHA 30 certifications, background-checked employees, and membership in professional associations like the Professional Background Screening Association (PBSA). Advantage Maintenance Inc. holds all of these and is also a Certified MicroGuard® technology applicator.
Why does dedicated crew assignment matter for office buildings?
When the same people clean your building every time, they learn the layout, remember your preferences, and spot issues before they become problems. Advantage Maintenance Inc. assigns dedicated crews to every location for accountability and consistency.
