Commercial Pressure Washing Bids for Sidewalks and Drive-Thrus
Write commercial pressure washing bids with clear surface scope, runoff controls, detergent use, access windows, safety notes, photos, exclusions, and customer approval.
Article
The hard part of a commercial pressure washing bid is not the square footage.
The hard part is everything attached to that square footage.
A restaurant owner asks for the drive-thru lane, menu board pad, grease trail near the dumpster, front sidewalk, and patio edge. A property manager wants five storefront walks cleaned before tenants open. A convenience store wants oil spots lifted around the entry and fuel-island walks rinsed without blocking morning traffic. The buyer wants "pressure washing." The job is really a mix of surface condition, runoff control, detergent choice, traffic routing, water access, customer hours, nearby glass, landscaping, public walkways, and proof that the work was completed.
If the pressure washing bid only says "clean sidewalks and drive-thru lane," the crew will discover the real scope at 5:30 a.m. with a hose stretched across a customer route and wash water moving toward a storm drain.
A better bid names the work before it becomes a 5:30 a.m. field decision. It should connect the site assessment checklist, pressure washing quote, pressure washing proposal, contract agreement, field work order, completion photos, and final invoice. The pressure washing document catalog gives the basic forms. The commercial bid decides what belongs in them.
For sidewalks, drive-thru lanes, storefronts, dumpster pads, parking-garage walks, service alleys, patios, and entry aprons, write the bid around six questions:
- What surfaces are included and excluded?
- What is on the surface now?
- Where will wash water and debris go?
- What cleaner, degreaser, or other chemical is being used?
- When can the work happen without creating an access or slip hazard?
- What proof will the customer receive after the crew leaves?
That is the difference between a price and a plan.
Start with the surface map
Commercial buyers often describe work by tenant, lane, or building face. Crews need a surface map.
Break the bid into sections:
| Area | What to record |
|---|---|
| Front sidewalk | Linear frontage, approximate square footage, pedestrian route, planter boxes, door swings, glass, mats, and tenant hours. |
| Drive-thru lane | Lane length, ordering station, menu board, canopy posts, curb islands, tight turns, parked vehicles, stacking hours, and reopening time. |
| Dumpster pad | Grease, food waste, enclosure walls, drain location, pad slope, pest conditions, and whether hot water or degreaser is included. |
| Patio or outdoor seating | Furniture moving, grease, gum, planters, pavers, outdoor outlets, lights, umbrellas, and dry-time expectations. |
| Storefront apron | Gum, oil, rust, paint, battery residue, spills, chewing tobacco, door thresholds, ADA route, and glass splash risk. |
| Service alley | Loading times, delivery trucks, back doors, employee traffic, grease barrels, mop sinks, and waste containers. |
Use the work request intake to capture the buyer's request, but do not price from the phone call alone. The field estimate should produce a marked photo set or a short map. Name each area in the bid the same way it will appear on the work order and invoice.
Weak scope:
Pressure wash sidewalks and drive-thru lane.
Better scope:
Clean approximately 2,850 square feet: front public sidewalk from Suite 101 to Suite 108; restaurant drive-thru lane from entry curb to pickup window; menu board pad; dumpster pad inside enclosure; and rear service apron. Excludes storefront glass cleaning, interior mats, painted curb repair, oil stain removal beyond listed treatment, storm-drain cleaning, landscape restoration, and after-hours security.
That wording gives the customer a real boundary. It also gives the crew a route.
Separate cleaning from stain removal
Commercial pressure washing bids get weak when "clean" means every stain disappears.
Concrete can hold oil, tannin, rust, gum, tire marks, food grease, paint, battery acid, fertilizer, irrigation staining, and years of tracked-in dirt. Some marks rinse. Some lighten. Some need heat, dwell time, chemical treatment, mechanical work, repeat visits, or a different trade. Some are permanent damage.
Write the expected result by condition:
| Condition | Bid language |
|---|---|
| General dirt and organic growth | Included as ordinary cleaning for listed surfaces. |
| Gum | Included only where listed, with scraper, heat, or spot treatment if priced. |
| Food grease | Degreaser and hot-water treatment included or priced as an alternate. |
| Oil spots | Spot treatment included for listed areas; complete removal not guaranteed. |
| Rust, battery, fertilizer, or irrigation stains | Excluded unless separately treated and tested. |
| Paint, coating, sealer, or graffiti | Excluded unless listed with method, test patch, and surface-risk approval. |
| Efflorescence or mineral deposits | Excluded or priced as specialty treatment. |
| Damaged concrete, spalled surface, loose mortar, flaking paint, or failing coating | Pre-existing condition; cleaning may expose damage. |
The hidden conditions workflow applies here. If the customer wants a visible stain removed, do not hide that inside the base square-foot price unless you have tested the surface and priced the method.
Use before photos. Circle the problem areas. Say what the base cleaning includes. Say what is an alternate.
For example:
Base bid includes surface cleaning for loose soil, organic film, and ordinary food-service residue. Bid includes up to 18 gum-removal spots marked in photos P-04 through P-07. Oil and grease staining at the dumpster pad will be treated with listed degreaser and hot water, but deep-set staining, prior etching, failed sealer, rust, paint, and permanent discoloration are excluded unless approved as specialty stain work.
That is not overexplaining. It is how you avoid selling a miracle.
Put runoff in the bid
Runoff is the line item many small bids skip.
EPA explains the basic public problem: stormwater runoff can collect pollutants and carry them to nearby waters. EPA's NPDES permit basics explain the federal permit framework for pollutant discharges, while EPA's municipal stormwater guidance explains that municipal separate storm sewer systems operate under permit programs that regulate stormwater discharges.
A small pressure washing contractor does not need to turn the bid into an environmental law memo. But the bid should not ignore runoff. Federal rules set the frame; local stormwater and sewer rules usually decide the practical method. Sacramento County, Portland, and Charlotte-Mecklenburg are examples of local programs that publish pressure washing or mobile-washing guidance for keeping wash water, pollutants, soaps, or contaminated residue out of storm drains unless a permitted or approved path applies. Do not treat "biodegradable" detergent as permission to drain wash water; local guidance can still require capture, filtering, sanitary-sewer approval, or offsite disposal.
The practical bid question is simple:
Where will the water go when we start washing?
Record:
- nearby storm drains, curb inlets, trench drains, catch basins, and loading-dock drains;
- whether the surface slopes to a landscaped area, sanitary sewer cleanout, oil-water separator, interior drain, storm drain, public street, or neighboring property;
- whether the work involves only clean water rinsing or detergent, degreaser, oil, grease, food waste, paint chips, sediment, or other contaminants;
- whether drains need mats, berms, socks, plugs, vacuum recovery, sump pump routing, or customer approval;
- whether disposal to sanitary sewer needs property-owner, local utility, or pretreatment approval;
- whether the customer has an existing stormwater plan, restaurant grease policy, or property-manager procedure.
Do not write "environmental compliance included" unless you know exactly what that means. Write the method:
| Runoff condition | Bid decision |
|---|---|
| Clean rinse water on a low-risk sidewalk | Use only if local rules allow it; document the rule check, drain observation, pre-cleaning, and no-detergent assumption. |
| Detergent or degreaser used | Capture, block, contain, redirect, or dispose under local rule and product instructions. |
| Grease or food residue near dumpster pad | Treat as higher-risk wash water; recovery or approved disposal may be needed. |
| Oil spots or petroleum residue | Do not wash oily wastewater to storm drain; price containment and disposal path. |
| Storm drain within work zone | Mark it, protect it, and write who is responsible for drain controls. |
| Sanitary sewer disposal proposed | Confirm customer and local utility permission before relying on it. |
| No approved disposal path available | Bid should exclude the work until a disposal method is approved. |
This is where a commercial bid may need a separate runoff-control line. A competitor who ignores recovery may look cheaper because the cost is missing, not because the job is the same.
Do not bury detergent decisions
Detergent choice changes price, dwell time, plant protection, disposal, PPE, and customer expectations.
A bid should say:
- product type or purpose, such as neutral cleaner, degreaser, sodium hypochlorite solution, surfactant, gum remover, rust remover, or specialty stain treatment;
- which surfaces receive chemical treatment;
- whether the product is applied by downstream injector, pump sprayer, X-jet, foam, or manual spot application;
- dwell time before rinse;
- dilution or applied concentration where the customer and crew need it;
- rinse procedure;
- plant, glass, metal, painted surface, sign, and entry-door protection;
- SDS availability and who supplies the product;
- whether customer approval is needed before substitutions.
OSHA's hazard communication rule is the workplace backstop for chemical information: labels and safety data sheets matter when employees handle hazardous chemicals. EPA's pesticide-label guidance is a separate reminder for products regulated as pesticides, disinfectants, sanitizers, or antimicrobial treatments: directions and use sites on the label are not decoration. If the job involves an EPA-registered product, do not write a bid that promises a use the label does not support.
For ordinary commercial flatwork, the wording can stay plain:
Degreaser included for dumpster pad and drive-thru order lane only. Product to be applied to pre-wet surface, allowed to dwell per label and site condition, agitated where needed, and rinsed with hot water. Contractor will protect adjacent plants, storefront glass, painted signs, door hardware, and exposed metals from direct chemical application where practical. Specialty rust, paint, battery, fertilizer, and mineral staining excluded unless separately approved.
The pressure washing work order should then carry the exact mix, method, and crew instructions. The bid sets the promise. The work order tells the crew how to keep it.
Access is part of the price
Commercial flatwork often has a tiny work window.
The restaurant opens at 6 a.m. The first coffee customers arrive before the crew finishes rinsing. The property manager wants the sidewalk dry before tenants unlock. The drive-thru cannot close during lunch. The trash hauler arrives at 4:45 a.m. The water spigot is behind a locked gate. The only parking spot for the trailer blocks delivery.
That is not scheduling trivia. It is bid scope.
Write access details into the pressure washing contract and the field work order:
| Access item | Bid field |
|---|---|
| Work window | Start time, stop time, reopening deadline, quiet-hour limits, and rain date. |
| Customer traffic | Pedestrian route, drive-thru closure, cones, barricades, caution tape, and who notifies tenants. |
| Water source | Spigot, hydrant permit if applicable, customer water permission, backflow requirement, tank fill plan, and hose length. |
| Power | Whether power is needed, which outlet is allowed, and extension-cord limits. |
| Keys and gates | Who opens, alarm code, lockbox, delivery gate, dumpster enclosure, roof or patio access. |
| Vehicles | Trailer parking, hose route, loading zone, delivery conflict, and after-hours towing risk. |
| Restrooms and cleanup | Crew facilities, trash disposal, where solids and debris go, and who resets furniture. |
OSHA's walking-working surface rule requires walking-working surfaces to be kept in a clean, orderly, and sanitary condition. Where wet processes are used, the rule requires drainage and, to the extent feasible, dry standing places. That rule is written for workplace safety, but the field habit is useful for customer-facing pressure washing too: wet public routes, cords, hoses, surface cleaners, chemical residue, and reopened entrances need controls.
CDC's pressure washer safety guidance adds the equipment-specific reason to write those controls down: high-pressure spray can cause serious wounds, throw objects, create electric-shock hazards, and create carbon monoxide risk when gasoline-powered equipment is used in or near enclosed spaces. The bid does not need a safety lecture, but the work order should name the route, barriers, electrical precautions, bystander controls, ventilation limits, and stop-work points before the crew starts.
Do not let the crew invent the controls at the curb.
Use the job hazard analysis or safety inspection checklist when the job involves early-morning traffic, public sidewalks, drive-thru lanes, dumpsters, chemicals, ladders, night work, slippery surfaces, or shared property access. The work order safety briefing is the right habit: scope, hazards, controls, customer notes, and sign-off should live on one field-ready page.
Surface risk needs a photo record
Pressure washing can reveal damage the customer did not notice before.
It can also cause damage when the method is wrong.
Document both.
Before the job, photograph:
- cracked, spalled, scaled, or patched concrete;
- loose pavers, failed polymeric sand, open joints, and uneven slabs;
- flaking paint, failing sealers, oxidation, chalking, and old coatings;
- loose mortar, soft brick, damaged stucco, EIFS concerns, wood rot, and exposed caulk gaps;
- door thresholds, weatherstripping, low weep holes, and water-entry risks;
- loose signage, decals, menu-board edges, lighting, cameras, doorbells, sensors, and outlets;
- landscaping, planters, mulch, turf, irrigation heads, and sensitive plants;
- glass, aluminum, painted metal, stainless, anodized surfaces, and nearby vehicles.
Then write the method boundary:
Contractor will use cleaning method appropriate for listed surfaces. Customer acknowledges documented pre-existing cracks, spalling, failing coating, open joints, loose mortar, oxidation, water-entry risks, and staining. Contractor is not responsible for the documented pre-existing condition itself or for cleaning results on surfaces excluded from the approved scope. Any requested specialty stain treatment, higher-pressure cleaning, coating removal, or unlisted surface cleaning requires written approval before work continues.
That paragraph belongs in the contract or scope attachment. The photo references belong on the work order and completion record.
Use a change order if the customer asks for extra stain treatment, additional storefronts, patio furniture washing, dumpster enclosure walls, signage, glass, awnings, facade washing, or another pass after seeing the first clean area. A verbal "while you are here" request is how a morning route turns into unpaid labor.
Build the bid as a route
Commercial pressure washing should read like a route plan, not just a price page.
For a small shop, a practical bid structure is:
| Bid section | What it should include |
|---|---|
| Customer and site | Legal customer, property name, address, authorized contact, tenant contacts, and after-hours access. |
| Work areas | Surface map, square footage, photos, included and excluded areas, and priority order. |
| Existing condition | Dirt, algae, gum, oil, grease, rust, paint, failed coating, damaged surface, and water-entry risks. |
| Method | Hot or cold water, pressure range, surface cleaner, soft wash, hand detail, gum removal, degreaser, and dwell time. |
| Runoff controls | Storm drain locations, containment method, recovery plan, disposal path, and customer approvals. |
| Access and traffic | Work window, drive-thru closure, pedestrian controls, cones, hose route, trailer parking, and reopening check. |
| Protection | Plants, glass, signs, metals, painted surfaces, doors, outlets, vehicles, and nearby merchandise. |
| Safety | PPE, slippery surface controls, public route controls, chemical handling, and night-work notes. |
| Proof and closeout | Before/after photos, issue notes, customer walkthrough, exception list, and completion sign-off. |
| Commercial terms | Price, alternates, expiration, deposit, cancellation, rain reschedule, change-order rule, and invoice timing. |
This is where the bid connects to dispatch. The estimator should be able to hand the approved bid to the office and produce a work order without guessing.
If the job is recurring, add frequency and escalation rules. Monthly drive-thru cleaning is not the same as a one-time cleanup after years of buildup. The recurring cleaning contract workflow has the same lesson: frequency, exclusions, access, supplies, inspection, and sign-off have to be explicit or the account slowly expands.
Write the closeout before the crew starts
A clean closeout starts in the bid.
Tell the customer what proof they will receive:
- before photos of included areas;
- close-up photos of pre-existing damage or excluded stains;
- drain-protection photos where runoff controls are part of the scope;
- after photos from the same angles;
- list of areas cleaned;
- list of areas skipped and why;
- note on stains that improved but remain;
- note on customer access failures, parked cars, locked gates, blocked dumpster pads, or unsafe conditions;
- customer walkthrough or manager acknowledgement;
- invoice line tied to the approved bid.
Use a completion sign-off when the customer or property manager is available. Use a service report when the buyer needs a record after hours. For multi-tenant sites, a simple closeout email with photo links and exceptions can prevent the next-morning complaint from becoming a free return trip.
The daily field handoff report is useful on longer routes or multi-site jobs. It gives the office the facts before anyone has to reconstruct the night from texts.
A sample commercial pressure washing bid note
Use plain language.
Scope includes pressure washing the front sidewalk from west tenant line to east tenant line, the restaurant drive-thru lane from entry to pickup window, menu board pad, and dumpster pad inside enclosure. Work to be performed between 4:30 a.m. and 7:00 a.m. before customer traffic. Customer to provide water access at rear hose bib and unlock dumpster enclosure by 4:15 a.m.
Base cleaning includes removal of loose soil, organic film, ordinary food-service residue, and listed gum spots. Dumpster pad includes degreaser and hot-water treatment. Deep oil staining, rust, paint, failed sealer, concrete spalling, coating removal, storm-drain cleaning, glass cleaning, landscape restoration, and unlisted tenant areas are excluded unless approved by change order.
Contractor will protect marked storm drains with listed controls and will not route detergent, degreaser, oil, grease, recovered solids, or contaminated wash water to storm drains. Disposal method is based on customer-provided site information and local requirements. If approved disposal, drain protection, water access, or site conditions differ from the bid assumptions, price and schedule may change.
That is enough to start a real commercial job file.
It tells the buyer what they are buying. It tells the crew what to do. It tells the office what to invoice. And it gives both sides a way to handle stains, runoff, access failures, and extra requests without turning a sidewalk wash into a dispute.

Common questions
- What should a commercial pressure washing bid include?
- A commercial pressure washing bid should include the work-area map, square footage, existing conditions, cleaning method, detergent or degreaser use, runoff controls, access window, customer traffic controls, surface-protection notes, exclusions, proof photos, price, change-order rule, and customer approval.
- Can wash water from pressure washing go into a storm drain?
- Do not assume it can. Local stormwater rules decide the approved path. Some programs allow limited clean-water discharge only with controls, while wash water with detergent, degreaser, oil, grease, sediment, food waste, paint, or other contaminants may need containment, recovery, filtering, sanitary-sewer approval, or offsite disposal. Write the drain-control and disposal method into the bid.
- Should a pressure washing bid guarantee stain removal?
- Usually no. Guarantee only what you can control and verify. Separate ordinary cleaning from gum removal, oil treatment, grease treatment, rust removal, paint removal, sealer removal, and specialty stain work. Use photos, test patches, and written exclusions for permanent staining or damaged surfaces.
- Do I need to list chemicals in a commercial pressure washing bid?
- List the product purpose, surface, application method, dwell time, rinse procedure, protection steps, and any customer approval needed for substitutions. If hazardous chemicals or regulated products are used, the field work order should carry the exact mix, PPE, SDS reference, and label-driven instructions.
- How do I price drive-thru lane pressure washing differently from sidewalks?
- Drive-thru lanes often need tighter work windows, traffic controls, food-grease treatment, hot water, degreaser, lane closure, sign and sensor protection, and faster reopening. Price those conditions separately instead of treating the lane like ordinary sidewalk square footage.
- What photos should I take before commercial flatwork cleaning?
- Take wide photos of each included area, close-ups of stains and damage, storm-drain locations, access points, water sources, nearby glass and signage, landscaping, parked vehicles, and any blocked or excluded areas. Repeat after photos from the same angles.
- What happens if the customer adds extra areas while the crew is on site?
- Pause and write the change before cleaning the extra area. The change order should name the added surface, condition, method, price, schedule impact, and runoff or access controls. Do not let a verbal "while you are here" request become unpaid work.
- Is a work order necessary after the bid is signed?
- Yes. The bid sets the commercial promise. The work order gives the crew the route, pressure range, chemical mix, drain controls, access notes, safety controls, photos required, and closeout checklist for the actual visit.
