Illustration for Job Too Big for Your Rig? Partner, Rent, Sub or Pass

Choose before you send a price, not after the customer says yes. This guide is for the owner-operator asked to wash a building that’s past what the trailer can do today. If you’re the property manager reading the bid, see what property managers pay to wash apartment buildings instead.

First, size the job against your rig

Before you price anything, check three limits.

  • Reach. On a trade forum in August 2026, a washer with a 4 GPM machine asked how to bid 3- to 5-story apartments. One owner replied that his 12 GPM gas pump with 300 feet of hose reached about 40 feet with no wind. Another simply said you need a lift, because overspray and coverage get hard to control that high. Those are posters’ own accounts, but reaching the wall isn’t the same as an even rinse.
  • Water. A borrowed or rented bigger machine is only as good as the spigot feeding it. Time how long the site’s tap takes to fill a 5-gallon bucket. One minute means about 5 GPM, which falls short of what a 12 GPM machine uses.
  • Skills. In a May 2025 thread, a washer was asked to quote soft washing two large buildings, plus every window and both sides of the balcony glass. He had never cleaned windows, or a building.

Miss one of these, and a rental or partner may close the gap. Miss all three, and passing is usually the right call.

The four options side by side

Option What it costs you Best when Watch for
Partner with another washer A share of the job, agreed up front You’re short on hands or one skill, like glass or height Whose insurance covers what, and who talks to the customer
Rent a lift (60-ft articulating boom) About $339–$400 a day, or $1,280 a week at one yard, plus delivery and fuel Height is the only gap Operator training, and how long each drop takes to rinse
Subcontract to a bigger company A fee or margin you agree in writing The job is far past your gear and skills The customer may stay with them
Pass and refer Nothing up front You can’t do it well yet Refer someone you’d trust on your own house

Partnering: split the work, not the paperwork

Two companies on one site works when the roles are written down first. Decide who signs the contract, who invoices, and whose liability policy covers which part of the work.

The property manager will likely ask for a certificate of insurance. Texas’s insurance department says a certificate can’t alter, amend or extend the coverage in the policy. It also says to check the “Additional Insured” box when the policy has an endorsement naming the certificate holder. So ask a partner for the endorsement, not just the paper. Rules vary by state, so check yours. This isn’t legal advice.

Line partners up early. The May 2025 washer asked a couple of other companies to partner, but neither had the bandwidth, so he passed. If you’d rather grow your own crew instead, see hiring your first helper.

Renting a lift: cheap reach, but count the whole bill

A national rental marketplace lists a 60-foot articulating boom at $339 a day. One Texas yard lists a Z-60 model (the 60-foot class) at $400 a day or $1,280 a week, and a Z-45 model at $315 a day. That yard charges delivery, fuel, the damage deposit and any damages separately.

Watch the day count. At that yard’s rates, four days at $400 comes to $1,600, which is more than the $1,280 weekly rate. If the job runs past three days, price the week.

Two more things belong in the bid:

  • Training. OSHA’s rule says only authorized persons may operate an aerial lift, and a lanyard must be attached to the boom or basket while you work from it. Ask the yard what it offers, and don’t learn the controls on the customer’s clock.
  • The right lift. One washer from lower Alabama said he’d use a 60-foot articulated lift, not a cherry picker, on a commercial building. That gets you close enough to rinse the windows properly.

For domes, steeples or very tall walls, compare a lift with drone washing before you bid.

Subcontracting or passing: keep the customer

Handing a job to a bigger company can still pay. Agree in writing on any fee and on who speaks to the customer.

Passing can be the right call. In an April 2025 thread, a commercial cleaning company running an 8 GPM hot-water rig turned down a massive warehouse wash. Its commercial clients were already asking it to wash trash enclosures and restaurant and retail sidewalks, so that was the work it had.

When you say no, say what you can do. A short note works: “This building is past my equipment this year. I can keep your sidewalks and dumpster pads clean, and I’d recommend this company for the walls.” The manager remembers who was honest.

When you’re ready to bid buildings yourself, start with bidding your first commercial job. Every price here comes from a rental company’s own published page, and the forum examples are posters’ own accounts. How we check numbers.
