How It Works

1. Site Assessment

After requesting a proposal, we visit your property to assess service scope, access points, and site conditions. Everything we need to price the job accurately, documented in person.

2. Custom Proposal

We build a proposal specific to your property. Scope, pricing, and logistics reflect what the job actually requires, not a ballpark figure pulled from a form.

3. Schedule

Once approved, we set a service plan that works for your operation. We accommodate custom time windows and coordinate with your facilities or property management team directly.

4. Work Completed

Our crew checks in with your point of contact on arrival, completes the work, and checks out before leaving. You know when we’re on site and when the job is done.

Our Commercial Pressure Washing Process

We assess your property first and choose the right cleaning method for the job. We handle routine maintenance, post-construction cleanup, post-storm cleanup, and one-time cleans on your schedule.

Our Approach

Commercial surfaces vary: concrete, brick, pavers, metal panels, painted block. The wrong cleaning method can damage them. We assess the material, contaminants, drainage, and the surrounding area before any equipment comes off the truck. Detergents, pressure, and dwell time match what the job requires. We confirm access and logistics during the site assessment, not on arrival.

Patios, Sidewalks, Concrete Surfaces

Entry points and gathering areas get dirty fast and reflect directly on your property. We clean concrete, pavers, and hardscape without damaging surrounding landscaping or finished surfaces.

Parking Ramps

Oil stains, tire marks, fluid buildup, and biological growth are routine on parking decks and ramps. We handle both surface cleaning and detail work on drains and expansion joints. Scheduled maintenance keeps buildup from compounding between visits.

Parking Lots

Lot surfaces take the most abuse. We clean drive lanes, stalls, and perimeter areas — including oil spots, gum removal, and line prep cleaning before restriping if needed.

Commercial Pressure Washing FAQ

Surface type, how much traffic it sees, the type of that traffic (foot traffic, vehicles, etc.), and weather all play a role in how frequently you need service. Generally in Iowa, most commercial properties benefit from two cleanings per year: once in spring to remove salt and sand accumulation from Iowa winters, and once in fall before the weather turns. We recommend starting on the lower end and increasing frequency if needed, so you’re only receiving as much service as you actually need.

Usually yes but the results depend on how long the stain has been there and how deep it’s penetrated. Fresh oil stains come off reliably. Stains that have soaked into concrete over multiple winters are harder; we can significantly reduce them but complete removal isn’t always possible once the concrete itself has absorbed the contamination. We can give you an honest assessment during the site visit.

Yes. Water works into concrete pores during pressure washing, and if temperatures drop below freezing before the surface dries completely, that moisture expands and can damage the concrete. In Iowa, that’s why we typically limit outdoor concrete work to late spring through early fall. If freezing temperatures are in the forecast on your service date, we’ll reschedule.

It depends on surface area, contaminant type, and access. A straightforward sidewalk and entry area might take a few hours. A parking ramp or multi-building lot is a multi-day job. We give you a realistic timeline estimate during the site visit.

Yes. We coordinate service windows with you or your property management team directly. If a building entrance or parking area needs to stay accessible during business hours, we sequence work accordingly. Early morning and weekend scheduling is available for properties where daytime access isn’t feasible. We check in with your designated point of contact on arrival and before we leave.

Yes. Many of our commercial pressure washing clients are on scheduled maintenance agreements, typically once or twice per year and based on the property’s needs. Recurring contracts get priority scheduling and eliminate the need to request service each season.

  • We’ve had the guys from Larry’s Window Service doing our office windows since 2005. They always do a very complete and thorough job and are polite and easy to work with.
