What Janitorial Services Cover in Nassau County

Janitorial services are the recurring, scheduled cleaning that keeps your facility operational night after night. Unlike a one-time deep clean, janitorial services are the backbone of your building's maintenance — the five-night-a-week crews that empty trash, sanitize restrooms, vacuum floors, and keep common areas presentable. In Nassau County, where commercial real estate costs average $32–$48 per square foot annually, a clean building isn't just about aesthetics — it directly affects tenant retention and lease renewals.

  • Nightly trash removal and recycling across all occupied areas
  • Restroom cleaning and sanitization: toilets, sinks, mirrors, floors, supply restocking
  • Floor maintenance: vacuuming carpet, dust-mopping and wet-mopping hard floors
  • Surface cleaning: desks, counters, conference tables, reception areas
  • Kitchen and break room cleaning: countertops, sinks, appliance exteriors, floor care
  • Common-area maintenance: lobbies, hallways, elevator cabs, stairwells

How Janitorial Services Work With XIRI

Most janitorial companies in Nassau County send a crew and hope for the best. You get an invoice at the end of the month, and unless you personally walk the building at 11 PM, you have no idea whether the crew did a thorough job, a rushed job, or even showed up at all. Our model is fundamentally different: every shift is verified, every concern is documented, and there's a real person who checks the work.

  • Pre-shift: crew receives digital task list with room-by-room scope for your facility
  • During shift: crew scans NFC checkpoints in each zone — creating a timestamped cleaning record
  • Post-shift: Night Manager walks the facility and flags any quality gaps
  • Next morning: you see the verification report on your dashboard — every room, every time stamp
  • Monthly: account review with your dedicated facility manager to adjust scopes and address trends

What Janitorial Services Cost in Nassau County

Janitorial service pricing in Nassau County depends on three main factors: your facility's square footage, the cleaning frequency (how many nights per week), and any specialized requirements like medical compliance or floor care. Most facilities fall in the $800–$3,500/month range for five-night-a-week service. We provide all-inclusive pricing — labor, supplies, equipment, insurance, and verification are bundled into one monthly rate.

  • Small office suite (1,500–3,000 sq ft, 5x/week): $800–$1,400/month
  • Mid-size office (5,000–10,000 sq ft, 5x/week): $1,500–$2,800/month
  • Medical office (3,000–8,000 sq ft, 5x/week): $2,000–$3,500/month
  • Large commercial space (15,000+ sq ft, 5x/week): custom pricing based on scope

Frequently Asked Questions

What's the difference between janitorial services and commercial cleaning?

Janitorial services are recurring, scheduled cleaning — your nightly or weekly crew that handles trash, restrooms, floors, and common areas. Commercial cleaning is a broader term that can include janitorial services plus project-based work like deep cleaning, post-construction cleanup, or floor restoration. Most Nassau County businesses need both: a reliable janitorial program for daily maintenance, with periodic deep cleans scheduled quarterly.

How many nights per week do I need janitorial service?

Most Nassau County offices with 20+ employees benefit from five-night-a-week service. Smaller offices or those with lower foot traffic may do well with 3x/week. Medical offices almost always need nightly service due to compliance requirements and the volume of patient traffic. We'll recommend a frequency during your free facility walk.

Do you provide cleaning supplies and equipment?

Yes. Our janitorial programs are all-inclusive. We provide all cleaning supplies, equipment, and consumables. This includes vacuums, mops, cleaning chemicals, trash liners, and restroom supplies (paper towels, toilet paper, hand soap). You never have to manage supply orders or equipment maintenance.

What happens if my regular cleaning crew calls out?

Crew continuity is one of the most common concerns in Nassau County. With our managed model, we maintain backup crews trained on your facility's scope. If your regular crew member calls out, a trained backup fills in — not a random temp. Our Night Manager verifies the backup crew's work to the same standard.

Can I adjust my janitorial scope after we start?

Absolutely. We review your scope monthly and adjust based on seasonal changes, tenant feedback, or building usage patterns. Need to add conference room cleaning for event season? Scale back during summer when half the office is remote? We adjust the scope and the pricing accordingly.
