Building Washing for Algae, Lichen,
and Moss on Your Walls

Building Washing in St. Charles County MO

Algae, moss, and lichen build up on commercial building exteriors, especially on shaded walls where moisture lingers. St. Charles County’s warm, humid summers make that organic growth even more noticeable on the walls that see the least sun. At MidWest SoftWash, we use professional soft washing to remove buildup without high-pressure cleaning, keeping exteriors clean and well maintained. Call (636) 244-1024 to get that growth off your building.

Types of Buildings We Soft Wash,
From HOAs to Schools

We run the same soft wash on every building below, matching the solution to the surface in front of us.

HOAs & Subdivisions

We wash whole communities as one coordinated project, using the same low-pressure process on every building. Most boards pair it with recurring upkeep, which we cover in our Maintenance Plans further down the page.

Apartment Complexes

We soft wash apartment and multi-family complexes and coordinate access and scheduling with your property manager. Larger complexes run across multiple days, planned around residents from the start.

Churches

We clean church buildings with the same gentle soft wash, protecting the structure and the grounds around it.

Schools & School-District Buildings

We handle everything from a single school building to buildings across a full district, on a schedule that works with the calendar.

Medical Facilities & Retirement Communities

We soft-wash medical facilities and retirement communities with the care these sensitive properties require.

Office/Retail Buildings

We clean office and retail buildings with the same process, keeping the exterior looking the way tenants and visitors expect.

Insurance, Contracts, and Updates for Property Managers

We handle the paperwork before a crew ever arrives. We carry auto, general liability, workers' comp, and umbrella coverage. We send the certificate of insurance, a W-9, and a signed contract or MSA before work begins. We respond to RFPs and work straight from your written scope. On a longer project, you hear from us on the cadence you want, anywhere from daily to weekly, so a board or manager always knows where the job stands.

Why Property Managers Choose Us
for Building Washing

Here is what sets our building washing apart once the bids are in front of you.

A True Soft Wash, No Power Washer on Your Building

We perform a true soft wash: low pressure, professional cleaning solutions, and no power washer on the building. The power washer stays on a separate truck and never touches a soft-wash surface. We are one of the only companies in the area doing a real soft wash. Most companies that say soft wash still reach for a pressure washer.

SoftWash Systems Authorized, Certified Technicians

We are a SoftWash Systems authorized company. Every technician completes 40 hours of certification training before working on a property, and the team logs at least 60 credit hours of ongoing training every year.

After-Hours, Weekend, and Early-Morning Work

We work after hours, on weekends, and before dawn when a job calls for it. Time-sensitive sites like banks and auto dealerships need the crew out of the way before the doors open. A wash can start at three in the morning.

Experience at Commercial Scale

We handle large single buildings and multi-building communities alike, from a single church to the buildings across an entire school district. The commercial-grade equipment and crews are built for work at that size.

How a Building Washing Job Runs,
From Estimate to Walk-Around

Here is how a job goes, from the first visit to the final walk-around.

The On-Site Walk and Written Estimate

Reach out by call, text, or email, and we come out to walk the property with you. We measure every washable surface and hand back a line-itemed written estimate, with a digital copy to follow. If you run a formal process, we respond to your RFP and work from your written scope instead.

Approval and Scheduling

Once you approve the services, we schedule a specific day, typically within two weeks depending on the season. You get a confirmation email covering the date, time, services, price, and any prep reminders. We have the required paperwork in place before that day arrives.

Arrival and Scope Review

The crew calls 30 minutes ahead, introduces themselves on site, and reviews the full scope with you before anything starts.

Plant and Property Protection and Pre-Inspection

Before we apply any solution, we set up plant and property protection, and the lead tech pre-inspects the building. Delicate landscaping gets our plant-wash solution, which feeds the soil rather than stressing it.

The Soft Wash

We dial in the SoftWash Systems blend module for each surface and apply the matched soap and solution. We do most of the work from ladders, with harnesses where rooftop access is required. No power washer touches the building.

Walk-Around and Invoice

We walk the finished property with you top to bottom. Commercial invoicing is typically net-30, and if anything is not right, we make it right.

Commercial Maintenance Plans
for HOAs and Managed Properties

Pricing Details

Our Maintenance Plans put a commercial property on a recurring wash schedule instead of one-off calls, each plan built around the property it covers. They fit HOAs, apartment complexes, churches, schools, and managed portfolios that want to keep the exterior maintained without having to think about it.

  • Commercial Maintenance Plan: Recurring commercial maintenance (annual, semi-annual, or a cadence built around your property) with the communication cadence your property manager needs.

Our 100% Satisfaction Guarantee
on Every Building

We stand behind every job with a 100% satisfaction guarantee. If something isn’t right, call us. A territory manager reviews your concerns, and we send the crew back out as soon as possible, often the same day or the next. That covers every building on the job, not just the first one we touch.

Midwest Softwash is an incredible company. Very responsive and words cannot express how happy we are with the quality and craftsmanship. The guys were standing back and double checking their work and touching up spots as they went. Such care went into our job and we can't thank them enough. We had a difficult clean (we thought) with LP siding and these guys tackled it no problem. Hands down would refer this company to everyone! We are very happy and love our clean house!
Response from the owner:Lincoln, thank you so much! We're really glad our team took great care of your LP siding and that the attention to detail showed. That's exactly how we want every job to go. We'd love to work with you again!

Commercial Building Washing
Questions

Pricing is a custom commercial quote, with no flat published rates. Depending on the property, we price by square footage, per unit for HOAs and apartment complexes, or by the project. We provide a free in-person estimate, with every surface measured and listed on its own line.

It runs anywhere from part of a day to multiple weeks. A large HOA project has run a full two weeks for us, while a single building is often done in a day. We set the timeline at the estimate once we have walked the property.

No, it comes to pennies. We use your water on site, and at about a cent a gallon, even a large job barely registers. We washed a 25,000-square-foot building using under three dollars of water.

Yes, we often add oxidation restoration on HOA work. Oxidation is restoration, not a routine wash, and it’s most common on Hardie board and vinyl siding. It has to be done across the whole wall rather than one patch. We wet the surface, let the solution dwell, hand-brush the oxidation off, and finish with a UV-inhibiting wax, usually over two days. It is quoted separately from the building wash.

Yes, where a community wants it, we schedule those on separate dates and bill them to the individual homeowner. Window cleaning is exterior water-fed pole work only, with no interiors, and deck cleaning is a soft-wash clean with no staining.
