What should warehouse cleaning cost per sqft in Denver?

If you run a warehouse in Denver, you've probably been quoted janitorial numbers that range from laughable-cheap to laughable-expensive for the same building. This post lays out what the real numbers are, what moves them up or down, and how to spot a bid that's going to fall apart in month three.

All numbers below are 2026 Denver metro, based on what we see walking facilities in Commerce City, Central Park, Aurora, Montbello, Englewood, and Lakewood. No national averages. No PDFs from a franchise in Ohio.

The three ranges that matter

There are three services a facility manager actually buys from a warehouse cleaner. Each has its own price band. Don't let a vendor blur them together on a single proposal — that's how you end up paying deep-clean rates for a nightly sweep.

1. Routine janitorial (recurring)

$0.14–$0.32 per sqft per month. That's the honest band for Denver in 2026. A 25,000 sqft distribution center on a 3x/week schedule lands somewhere between $3,500 and $8,000 per month depending on restroom count, dock scope, and office footprint.

• $0.14–$0.22/sqft/mo — smaller facilities (5K–15K sqft), 1x/week, open warehouse floor, minimal office
• $0.16–$0.25/sqft/mo — mid-size (15K–50K sqft), 2–3x/week, typical dock + office + 2–4 restrooms
• $0.18–$0.32/sqft/mo — larger facilities (50K–150K sqft), 3–5x/week, multiple restrooms, break rooms, busier dock

2. Deep clean / degrease (one-time or quarterly)

$0.18–$0.35 per sqft for a full interior deep clean. Shop-floor degrease with an alkaline cleaner and a pressure washer runs higher — $0.35–$0.75 per sqft — because you're burning labor and rented equipment, not just bodies. A 10,000 sqft shop degrease in Commerce City typically comes in at $2,500–$3,500.

3. Post-construction cleanup

$0.30–$0.85 per sqft for combined rough + final. Always priced per sqft — never hourly. GCs drag jobs. If a cleaner is willing to go hourly on a post-con job, they've either never done one or they're planning to walk off halfway through.

The four things that actually move your price

Every facility is different, but in our experience the number on the bid is almost always driven by these four inputs — in this order.

1. Frequency

A 1x/week nightly costs roughly a third of a nightly 5-day schedule. But the per-visit price goes down as frequency goes up, because the crew isn't fighting a week of buildup every time they show up. If you're on 1x/week and your floors look rough by Wednesday, bumping to 2x/week usually costs less than 2x what you pay now. Ask for both quotes when a vendor bids.

2. Restroom count

Restrooms are the single most labor-intensive item per square foot in a warehouse. A full wipe-down, restock, and fixture detail runs 15 minutes per restroom. A 4-restroom facility on a nightly schedule eats ~20 hours/month just on restrooms — that's $500+ of loaded labor before you touch the warehouse floor. If your building has 6 or 8 restrooms, you should expect your quote to be 20–30% higher than a comparable sqft building with 2 restrooms.

3. Floor type and condition

Sealed concrete sweeps fast. An auto-scrubber can run 15,000 sqft/hr on open aisle. Unsealed concrete holds dust in the pores and slows everything down. Epoxy floors look easy but scratch if the wrong pad is used. And if your current floor is already behind — built-up grime, tire marks, spilled product in the pores — you're going to pay for a deep clean to get to baseline before routine pricing makes sense. A vendor that quotes you nightly rates on a filthy floor without flagging the restoration step is setting you both up to fail.

4. Dock and exterior scope

Dock pads, dock doors, and exterior approach concrete double the scope of a typical warehouse. If the bid includes 'dock doors inside and out' and 'concrete approach pad,' expect another 10–20% on the monthly number. Most cheap bids silently exclude the exterior, then nickel-and-dime you for pressure washing quarterly.

A worked example — 25,000 sqft, 3x/week

Let's take a real-ish Denver distribution center: 25,000 sqft, 3 nights a week, 4 restrooms, 1 break room, 1,500 sqft of office. Here's what actually goes into the number on the bid.

• Per-visit crew time: about 2 hours 40 minutes solo, or 1 hour 35 minutes with a 2-person team
• Monthly hours: ~34.7 hours at 3x/week across the month
• Loaded labor cost: 34.7 × $25.40/hr fully loaded (W-2 wage + FICA + workers comp + unemployment + supply allocation) = ~$881/mo
• Supplies and consumables: ~$85/mo
• True monthly COGS: ~$966
• Fair bid at 60–65% gross margin: $2,400–$3,200/mo
• Per-sqft math: ~$0.10–$0.13/sqft/mo — solidly in the middle of the market band

A quote in the $2,400–$3,200 range buys you W-2 crew, a written scope, photo QC, and an operator who plans to still be around in year two. A quote at $1,800 for the same scope buys you 1099 labor cycling every four months. A quote at $5,500 buys you a national franchise with overhead you don't need.

What a fair bid looks like on paper

A bid you can sign with confidence has five things on it. If any are missing, keep shopping.

1. Written scope of work naming every area and what gets done in it — restrooms, break rooms, warehouse floor, dock, offices
2. Frequency per area (some items don't happen every shift — high dusting is usually quarterly)
3. Flat monthly fee, not hourly
4. Consumables (toilet paper, soap, liners) spelled out — either we stock them at cost + markup, or you stock them, but it's on paper
5. Callback language — what happens when something gets missed, and how fast
