How Do Pressure Washing Contractors Send Estimates?

Short answer: How do pressure washing contractors send estimates? Usually without a site visit — a satellite measurement plus four photos from the customer — texted as a PDF the same day, because the homeowner called three companies that morning. The estimate names the method per surface (surface cleaner around 3,000 to 4,000 PSI on concrete, soft wash under 500 PSI on siding and roofs), states the minimum service charge as a number, holds the price about 30 days, and offers two or three bundled options.

Washing is the only part of this trade that is not a sales problem. The estimate is where the job is won, where the damage claim is prevented, and where the minimum charge stops being an argument. This page is about the delivery — how fast, in what format, how long it stands, and how the yes gets recorded. If you want the collection side of the same relationship, pressure washing customer won’t pay picks up where this leaves off.

How fast does the estimate have to go out?

Same day, and for most residential leads, same hour. A homeowner rarely waits for a favorite; they take the first quote that answers the question they asked.

Lead source	What the customer is doing	Realistic window
Inbound call, spring rush	Dialing the next three numbers on the list	Ballpark on the phone, PDF within the hour
Web form or social message	Comparing before anyone calls back	Reply in two hours, PDF that evening
HOA violation letter	Working against a stated deadline	Same day, with their deadline printed on the estimate
Realtor before a listing	Photo day is already on the calendar	Same day, dated to the photo date
Property manager or bid packet	Building a file of three bids	By the stated due date, insurance certificate attached
Neighbor who saw the trailer	Deciding while you are still set up	Verbally now, PDF before you pull away

The neighbor row is the highest-margin estimate you will ever send. You are already on the street, already unhooked, already filled. A price quoted over the fence and confirmed in a text before you leave skips the drive that usually eats a small job.

Do I have to walk the property before quoting?

Sometimes. Flatwork and simple house washes quote fine from a satellite tool and photos. Anything where the substrate decides the chemistry needs your eyes on it.

Job	Quote remotely	Drive it first
Concrete flatwork, straightforward	Yes — satellite area plus two photos	If the satellite image predates a new patio or extension
Single-story house wash	Yes — one photo per elevation	Chalky, oxidized, or failing siding
Roof soft wash	No	Always — pitch, access, gutter condition, plantings below
Wood deck or fence restoration	No	Always — species, prior coating, rot, board condition
Two-story or commercial	No	Always — water source, containment, after-hours window
Oil, rust, or artillery fungus	No	Always — the stain type decides the chemical and the passes

When you quote remotely, ask five questions before you write a number: is there a working outdoor spigot and is the property on a well, what is the clear width of the gate, has anything been painted or previously etched, are there pets or plantings against the wall, and is anyone home on wash day. Answers to those five are what keep a remote quote from becoming a losing job.

What belongs on the estimate that a phone quote leaves out?

The method. A phone quote is a number; a written estimate is a description of what you are going to do to somebody’s house, and that description is your damage defense.

Line	What it prevents
Surface with measured ft² or linear ft	”That is not what I thought I was buying”
Method and pressure band per surface	A customer expecting a wand on vinyl siding
Chemistry per surface, named	The “you just used water” callback
Post-treat, included or declined	Regrowth blamed on the wash
Water source and haul	Discovering a dead spigot with the trailer already unhooked
Access notes — second story, gate width, hose run	Setup time nobody agreed to pay for
Wash water containment and disposal	A commercial site asking mid-job
Minimum service charge, as a number	A forty-minute argument in the driveway
Exclusions in plain words	Oxidation, wood tannin, rust return, previously etched concrete
Price hold date	A March quote being demanded in August

Write the method plainly, because this is the sentence that survives a complaint: “Vinyl siding — soft wash applied below 500 PSI.” High pressure on vinyl drives water behind the panels into the wall cavity, and on an asphalt roof it strips granules and shortens the roof’s life. When a customer insists they want it “pressure washed,” the estimate is where you decline in writing and still keep the job.

The wash water line matters most on commercial bids. Runoff carrying detergent, oil, or grease into a storm drain is a discharge regulated under the federal NPDES stormwater program, with the specifics set by your state and municipality — which is why restaurant pads, dumpster corrals, and fuel islands ask about containment before they ask about price. Putting containment, recovery, and disposal on the estimate as priced lines is frequently the reason a property manager picks you over the cheaper bid.

How do I build the number that goes on the estimate?

Build it from your own costs, in this order, and only then compare it to what you hear other people charge.

1. Pick the unit per surface. Flatwork and house washes are ft². Gutter faces are linear feet. Small single-surface calls are the minimum charge.
2. Cost the chemistry from your own draw. Your bucket mix is not your applied mix — a downstream injector dilutes it further, and the draw ratio differs between injectors. Do a bucket test, record how much mix a known square footage consumed, and you have a per-ft² chemical cost that is actually yours.
3. Price labor at your loaded hourly cost. Wage plus payroll burden, machine and trailer payments, fuel, insurance, and the hours you cannot bill, divided by the hours you can.
4. Add overhead — phone, software, ads, the shop, licensing.
5. Add profit, and know which one you added. Markup and margin are not the same, and this is the most common arithmetic error in the trade. A 20% markup on $100 of cost gives $120, which is a 16.7% margin. To actually earn a 20% margin, divide the cost by 0.80 and charge $125.
6. Derive the minimum charge. Round-trip drive, unhook, fill, hose run, teardown, hook up, plus your hourly rate for the smallest job you will accept. That total is the floor, and most single-surface residential calls land under it, which is why it belongs on the estimate rather than in your head.

Whatever range you hear at the supply house is a sanity check only. Per-foot prices move sharply with region, water access, stain load, drive radius, and season, and a number that works on a rural route will bankrupt you in a dense metro where the drive is the job. Your cost decides; the range only tells you whether you are wildly off.

How many options should the estimate offer?

Two or three, and they should be built around the fact that your setup is already paid for once you are on site.

Option	What it holds	Why it converts
The thing they called about	Driveway, measured	The price they can compare to the neighbor’s
Same-setup bundle	Driveway, walk, porch, gutter faces	Every added surface skips a second drive and setup
Full exterior	House wash, all flatwork, post-treat, gutter brightening	The seasonal customer, and the one who wants it done once

Below the options, put a short add-on menu with a stated “while the trailer is hooked up” price — a deck, a fence run, the back patio. That menu is what turns a job sitting near your minimum into an afternoon worth driving to. Do not offer five tiers. Three is a decision; five is a research project the customer postpones.

How long should the price stay good?

Around 30 days for residential, and say so on the document. Chemical prices move, fuel moves, and the surface itself moves: a driveway you measured and photographed in March has a different organic load in July, and a quote written before pollen season describes a house that no longer exists.

Add one clause to every remotely-produced estimate: price subject to on-site verification of measurements, water source, and access. That sentence is not a loophole, it is the thing that lets you quote from satellite at all.

When do I follow up, and how many times?

When	What to send
48 hours	One text: “Any questions on the driveway quote?” Nothing else
Day 7	The before/after photo set from a similar job on their street
Day 21	A scheduling nudge tied to something real — a route day in their area
Next season	A re-touch when growth comes back, with the old measurements attached

Three touches, then stop and move it to the seasonal list. The photo at day 7 does more work than any discount, because pressure washing sells on contrast and nobody can picture their own driveway clean.

How does the customer’s yes get recorded?

For residential, a text reply saying “approved” or “let’s do it” is enough, and it should be screenshotted and filed with the estimate. Confirm three things in the same thread: the date window, the water source, and the pet and plant plan.

For commercial, a property manager, or anything over your own threshold, get a name, a signature, and a date on the estimate PDF, plus a purchase order number if their system uses one. Missing PO numbers are the single most common reason an otherwise clean invoice sits for sixty days, which is the whole subject of how to get clients to pay. Deposits are rare on residential washing and normal on anything needing a rented lift, a containment setup, or after-hours access.

What do I keep once the estimate turns into a job?

The approved estimate, the photos the customer sent, the condition notes, and the measurements — those four become the invoice. The moment they say yes, the estimate stops being the document that matters, and the priority becomes billing the measured surfaces and the chemistry exactly as quoted, which is the checklist in what to include on an invoice.

Keel is an iOS app that runs entirely on the device — no account, no bank connection, no cloud, no login, and an App Store privacy label reading Data Not Collected. Estimates are still being built and have not shipped, so this is not the tool that writes the quote. What it does is the minute after the job is done: the invoice goes out from the driveway with your logo, your numbering, and the payment link as a QR code the customer scans off your screen. The sodium hypochlorite receipt gets photographed at the supply counter and read on the phone by Apple Intelligence, tows between jobs get logged, and the year exports as one file or as the Accountant Pack — a CSV plus a one-page summary PDF. The ledger is append-only and hash-chained. Free is $0 with unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 lifetime purchase, not a subscription. Your chemical and fuel receipts also feed the deduction side covered in self-employed tax deductions.

Frequently asked questions

Should a pressure washing estimate be given over the phone?

Give a ballpark on the phone to keep the caller from dialing the next company, then send the written estimate the same day. The phone number is a range with conditions attached; the PDF is the one with measured square footage, the method per surface, and the minimum charge. Quoting only by phone is how soft wash jobs get sold as high-pressure ones.

How long should a pressure washing estimate stay valid?

About 30 days is standard for residential work, printed as an expiration date on the document. Chemical and fuel costs move, and the surface itself changes — a driveway measured in early spring carries a heavier organic load by midsummer. Add a clause making the price subject to on-site verification of measurements, water source, and access when you quoted remotely.

Can I quote a house wash from satellite photos?

For a straightforward single-story house wash, yes, with one photo per elevation from the customer. Do not quote a roof, a wood deck, a fence, or anything with oil or rust remotely — pitch, access, board condition, and stain type decide the method and the passes. Always confirm the outdoor spigot, the gate width, and whether the property is on a well.

Should the minimum charge appear on the estimate?

Yes, as a stated number rather than something the customer meets on the invoice. Setup, fill, hose run, teardown, and the round trip are most of the cost on a small job, so single-surface residential calls routinely fall below the floor. Saying it before you drive out turns a potential argument into an easy upsell of a second surface.

How many times should I follow up on a pressure washing quote?

Three, then stop. A short question at 48 hours, a before-and-after photo set from a similar nearby job at day 7, and a scheduling nudge around day 21 tied to a real route day in their area. After that, move them to the seasonal list and re-touch when growth returns, attaching the measurements you already took.

Do I need a deposit before a pressure washing job?

Rarely on residential work, since the whole job is usually one visit and payment is due on completion. Ask for a deposit when the job requires a rented lift, a wash water containment setup, after-hours access, or a large chemical purchase specific to that customer. Commercial and property management work more often runs on a purchase order with net terms instead.
