By Cory Cooper, Mr. Suds Residential Window Cleaning & Power Washing. Commercial work handled by our commercial team. Family owned, fully insured, serving Kingwood and the North Houston Metro area for over 20 years.
A property manager called us last spring with two bids in hand for the same strip center.
One was a few hundred dollars. The other was a few thousand. Same property, wildly different numbers, and no way to tell which one was fair.
That is the problem with commercial pressure washing pricing. It feels like a black box.
So we are going to open the box. After 20+ years cleaning exteriors around North Houston, we will show you what commercial work actually costs, how we build an honest quote, and how to read any bid so you never overpay or hire the wrong crew.
How Much Does Commercial Pressure Washing Cost?
Most commercial pressure washing runs about $0.08 to $0.30 per square foot. Full building exteriors can range from roughly $0.15 to $0.90 per square foot depending on height and condition. As a whole project, most commercial jobs land between $500 and $5,000 or more. Your price depends on the surface, the size, the access, and how dirty it is.
There is no single flat rate, because a parking lot and a greasy dumpster pad are nothing alike. The surface drives almost everything.
Pricing by surface type
Here is how the common commercial surfaces tend to price out:
| Surface | Typical price | Notes |
| Building exteriors | $0.15 to $0.90 / sq ft | Height and lifts raise it |
| Sidewalks and storefronts | $0.10 to $0.30 / sq ft | Gum and grime add labor |
| Parking lots | $0.03 to $0.20 / sq ft or $8 to $20 per space | Large flat areas, priced low per foot |
| Parking garages | $0.10 to $0.25 / sq ft | Tight access, oil stains |
| Dumpster pads | $0.75 to $1.00 / sq ft | Grease, bacteria, and odor |
Notice the spread. A dumpster pad can cost more per square foot than the entire parking lot around it.
What drives the price up or down
A few things move a commercial bid:
- The total size and how often you schedule service
- Access and height, since lifts or scaffolding add cost
- After-hours work to avoid disrupting your business
- Traffic control and water recovery requirements
- Tough stains like oil, grease, gum, graffiti, and mold
Field note: On that strip center, the dumpster pad alone cost more per foot than the whole lot. Years of grease and food waste had soaked into the concrete, and that takes hotter water, stronger degreasers, and more time.
How Does Mr. Suds Quote a Commercial Job? (So You Can Compare Bids Fairly)
We quote commercial jobs from an on-site walkthrough, not a guess over the phone. We measure the surfaces, note the problem areas, factor in access and timing, then choose the fairest pricing model and put it in writing. A good commercial bid is specific. It lists the square footage, the surfaces, the scope, and the schedule, so you know exactly what you are paying for.
If a company gives you a firm price without ever seeing the property, be careful. They are guessing, and that guess usually shows up as a surprise later.
Our quoting process, step by step
Here is how we build a commercial estimate:
- Walk the property with you and look at every surface
- Measure and identify what we are cleaning
- Flag the problem areas, like oil, gum, graffiti, or heavy mold
- Factor in access, timing, and water recovery
- Choose the pricing model that fits the job
- Put it all in a written, itemized estimate
That walkthrough is where a fair price comes from. It is also where we catch the things that quietly drive cost.
Per square foot, hourly, or flat rate?
Different jobs call for different pricing. Large flat surfaces like lots and sidewalks usually price per square foot.
Complex properties, with mixed surfaces or tricky access, often get a custom flat bid for the whole scope. Either way, the goal is a number you can understand and compare.
How much do cleaning companies charge?
It varies by surface and scope, which is why a single number can be misleading. The thing to look for is not just the total, it is whether the bid is itemized. A clear bid beats a vague lump sum every time.
Is $0.15 Per Square Foot a Good Price for a Cleaning Job?
It depends on the job. For interior janitorial cleaning, $0.15 per square foot is a fair, mid-range rate, since most offices run about $0.10 to $0.18. For exterior pressure washing, the right number changes by surface, because a flat parking lot, a building wall, and a greasy dumpster pad are not priced the same. A single per-foot number only makes sense once you know the surface.
So if someone quotes you a flat per-foot rate for an entire commercial property, ask what it covers. The honest answer is that different surfaces carry different rates.
Why one rate does not fit every surface
Flat ground is fast to clean and prices low per foot. A tall building wall needs lifts and more care, so it costs more.
A dumpster pad is small but brutal, full of baked-in grease and odor, so it carries the highest rate of all. Lumping them into one number hides what you are really paying for.
What Does a Larger Job Cost, and How Long Does It Take?
Cost scales with square footage and surface. As a janitorial example, a 6,000 square foot office at $0.15 per square foot is about $900 per cleaning. Exterior pressure washing of the same building is priced by surface instead. On time, a 1,000 square foot interior space takes roughly 1 to 2 hours, while exterior pressure washing time depends on the surface, the grime, and the equipment.
Bigger is not just more money. It is also more planning, especially for access and scheduling around your business hours.
A quick note on interior versus exterior
Those office figures are interior janitorial benchmarks, and they are useful for budgeting. Just know that we focus on exterior pressure washing and commercial window cleaning, which we price by surface.
So for a building, we are quoting the walls, the walkways, the lot, and the pads, not the carpets and breakrooms inside.
How long commercial exterior jobs take
Exterior timing comes down to a few things:
- The total square footage and number of surfaces
- How heavy the staining and growth are
- Access, height, and whether lifts are needed
- Whether it has to be done after hours
A small storefront might take an hour or two. A full property with a building, lot, and pads can be most of a day.
How to Read and Compare a Commercial Cleaning Bid
A strong commercial bid is itemized, names the surfaces and square footage, states the schedule, and comes from an insured company. To compare bids fairly, look past the bottom-line number to the scope, the insurance, the references, and how the work is structured. The cheapest bid often skips steps you will pay for later.
That property manager with two bids? The cheap one had no scope and no proof of insurance. The higher one listed every surface and a schedule. The “expensive” bid was actually the safer deal.
The 4 types of bidding (what they mean for you)
You may run into different bidding setups, especially for larger properties:
- Open bidding. Anyone can submit. Common for public projects, and it tends to push prices down.
- Selective bidding. You invite a short list of vetted, qualified vendors.
- Negotiated bidding. You pick one trusted vendor and work out the details together.
- Serial bidding. A pricing framework used across a series of similar jobs over time.
For most property managers, selective or negotiated bidding gets you reliable vendors instead of just the cheapest one.
Signs of a poorly cleaned building
You can usually spot a bad job fast. Watch for these:
- Streaky walls or clean stripes next to dirty ones
- Stains and grime that are still there after the “clean”
- Corners, edges, and low spots left untouched
- No consistent schedule and a vague scope of work
A quick bid-evaluation checklist
Before you sign, make sure the bid includes:
- Itemized scope and the surfaces being cleaned
- The square footage and pricing model
- Proof of insurance
- References from similar properties
- A clear schedule, including after-hours if needed
- Before and after photos on past jobs
Industry Questions People Also Ask
A few questions come up that are more about the cleaning industry than your specific bid. Here are quick, honest answers.
What are the 7 stages of cleaning?
In the interior janitorial world, the 7 stages are a standard process for cleaning a room. They are: empty the trash, dust high surfaces, dry mop or vacuum, disinfect high-touch areas, spot clean, do a final inspection, then wet mop.
That framework is for interior cleaning. Exterior pressure washing follows its own process: pre-treat the surface, apply the cleaning solution, let it dwell, then rinse.
What type of cleaning makes the most money?
Commercial and specialty cleaning tend to be the most profitable. That includes post-construction cleanup, high-rise window cleaning, floor restoration, and exterior pressure washing and soft washing.
The reason is simple. These jobs need real skill and equipment, so they command higher rates than basic cleaning.
