What Property Managers Should Expect from a Commercial Pressure Washing Vendor

Hiring someone to wash a house is a low-stakes decision. If it goes badly you have a streaky wall and a bad afternoon.

Hiring someone to wash a commercial property is not. You are handing a contractor access to a site with tenants, customers, liability exposure and environmental obligations attached. Most of what distinguishes a commercial vendor from a residential one has nothing to do with how well they clean concrete.

Here is what to ask for, and why each item exists.

Insurance, before anything else

Ask for a certificate of insurance before you ask about price. Most property managers already know this; it is first on the list because it is the item most often quietly skipped.

What you want to see:

• General liability, typically $1m per occurrence. A pressure washer can break a window, flood a storefront or damage a vehicle without anyone being careless.
• Workers' compensation. This is the one that matters most to you. If an uninsured contractor's employee is injured on your property, the exposure has a way of finding its way to the property owner.
• Your entity named as certificate holder, and as additional insured where your agreements require it.

A contractor who can produce a current COI within a day of being asked is a contractor who has done this before.

A written scope that lists surfaces

"Pressure wash the property, $2,400" is not a scope. It is an invitation to argue later about whether the dumpster pad was included.

A real scope names surfaces and areas:

• Sidewalks and entry areas, with linear footage or a defined boundary
• Building facade, and which elevations
• Dumpster enclosure and pad
• Drive-thru lane, loading dock, service areas
• Parking areas, and whether that means the whole lot or specified sections
• Awnings and canopies
• What is explicitly excluded

That last line prevents most disputes. A scope that says what is not included is a scope written by someone who has had the conversation before.

It should also state what the contractor needs from you: water access and whether a meter is required, power availability, which areas need to be coned off, and who holds keys or gate codes.

Off-hours scheduling, by default

A commercial contractor should assume they are working outside your operating hours without being asked. Early mornings, evenings, weekends: whatever keeps a hose out of your entrance while customers are arriving.

There are practical knock-ons worth confirming up front:

• Lighting. Night work needs the contractor's own.
• Noise. Some municipalities restrict equipment noise overnight in mixed-use areas. Worth checking for a property with residential neighbours.
• Access and security. Who opens up, who locks up, and whether anyone from your side needs to be present.
• Wet surfaces at opening. Concrete that has been washed at 4am should be dry and safe by the time the first customer arrives. If it will not be, you need signage.

Wash water, and why it matters more than people think

This is the item most residential contractors have never had to think about, and it carries real regulatory exposure for the property owner.

Under the Clean Water Act, storm drains discharge to surface water without treatment. Wash water carrying detergents, oil, grease or sediment is not permitted to enter them. In practice, enforcement across metro Atlanta jurisdictions focuses on the obvious cases, and the most obvious is restaurant grease.

For most general cleaning (a sidewalk, a building exterior, water only), this is straightforward and rarely an issue.

For restaurant kitchen pads, dumpster enclosures and drive-thru lanes, it is not. Those surfaces carry grease and food waste, and that runoff needs containing and disposing of properly, which means a vendor with reclaim equipment: booms or mats to block the drain, a vacuum recovery system, and a lawful disposal route.

The question to ask is simply: how do you handle wash water on the grease areas? A vendor who answers confidently and specifically has the kit. A vendor who looks puzzled is planning to send it down your storm drain, and it is your property on the citation.

Recurring schedules beat one-off cleans

Most commercial properties are better served by a rotation than by calling someone when things look bad.

The reason is cost. Dirt that is removed every quarter never fully bonds to the surface, so each visit is quicker. Let a site go two or three years and you are paying for a restoration clean: more time, stronger chemistry, sometimes hot water, and a result that may not fully recover.

Recurring work is also normally priced below one-time rates, because the contractor can plan routes and crews around it. Monthly suits high-traffic food service; quarterly works for most retail and office; twice yearly is often enough for a low-traffic office park.

The underrated benefit is budgeting. A fixed recurring line item is far easier to defend to an owner or an HOA board than an unpredictable annual surprise.

Questions worth asking

A short list that sorts vendors quickly:

1. Can you send a current COI naming us as certificate holder?
2. Will the scope specify surfaces and exclusions in writing?
3. What hours will you work, and what do you need from us for access?
4. How do you handle wash water on the grease areas?
5. Do you use hot water? (For grease, cold water and pressure alone will not do it.)
6. What does this cost on a quarterly rotation versus as a one-off?
7. Can you walk the site with me before quoting?

That last one matters more than it looks. A contractor who quotes a commercial property sight-unseen from an address is guessing, and a guessed price gets corrected later, usually upward, usually mid-job.

How we work

We walk the property with you first, put the scope and price in writing, and schedule service outside your trading hours. Certificates of insurance go out on request, normally same day. Recurring accounts are priced below one-time rates and go on a fixed rotation so the property never slides far enough to need an expensive recovery clean.

We cover retail centres, restaurants, office parks and HOA common areas across Cobb, Cherokee, Paulding and Bartow, and we travel further for commercial accounts and multi-site portfolios than we do for residential work.

If you manage a property anywhere around Marietta, Kennesaw or Acworth and want a straight price on a rotation, we will come and walk it.
