True Soft Wash House Washing
for St. Charles County Homes

House Washing in St. Charles County MO

Algae, lichen, and moss settle into the siding, brick, stucco, and EIFS on your home, and our hot, humid summers keep that growth coming back. A true soft wash clears it with low pressure, professional SoftWash Systems solutions, and no power washer anywhere on your home. Seeing growth creep across your walls? Call MidWest SoftWash at (636) 244-1024 for a closer look.

Every Exterior We Clean
Gets Its Own Soap Recipe

The material your home is clad in decides the cleaning solution we mix. We dial our blend to the surface in front of us, so brick, stucco, and fiber cement each get the recipe they need. Every exterior gets the same gentle, low-pressure soft wash.

Vinyl Siding

We soft wash vinyl at low pressure and set the solution strength for the panel. This is also where dark siding and dark trim get the careful finishing they need, a job we take on often.

Brick

Brick gets a soft wash with a solution matched to masonry. No power washer hits the surface, and no high pressure drives into the mortar joints.

Stucco

Stucco is cleaned with a soft wash and a recipe mixed for it. It shows up on many homes around here and is often handled badly by cleaners who reach for pressure.

EIFS

EIFS, the synthetic stucco on many newer homes, gets the same low-pressure soft wash with its own solution. Like stucco, it is easy to damage with pressure, so we never use it.

Hardie Board

Hardie board gets a soft wash with the fiber cement solution. The pressure stays low, and the finish stays even across the whole wall.

Why Homeowners Pick
Our Certified Crew for House Washing

Here is what you get when our crew washes your home, beyond the clean itself.

A True Soft Wash, No Power Washer on Your Home

We’re one of the only companies in St. Charles County that performs a true soft wash: low pressure, professional cleaning solutions, and no power washer touching your home or roof. Most companies that say ‘soft wash’ still reach for a pressure washer. We don’t. Your siding, trim, and fixtures never take a hit from high pressure.

Certified Technicians on Every House Wash

We’re a SoftWash Systems authorized company. Every technician completes 40 hours of certification training before working on your home, and our team logs at least 60 credit hours of ongoing training every year.

Specialists in the Homes Others Avoid

We take on the exteriors other companies turn down: dark siding and dark trim, luxury and custom homes, and historic properties. These surfaces show every mistake, so the right solution and a careful hand matter. That is the work we built this company around.

Photo Proof of Every Step

Every property gets full, timestamped photo documentation (pre-inspection, during, and after) sent straight to you. You see exactly what we saw and exactly what we did.

Your Landscaping Comes First

Before a drop of solution touches your home, we protect your plants and property. We follow a multi-step process to protect your landscaping from start to finish, and finish delicate plants with a plant-wash application that actually feeds the soil. We’re not here for speed; we’re here to protect your property.

How Our House Washing Works,
From In-Person Estimate to Walk-Around

The Free In-Person Estimate

Reach out by call, text, or email, and we come to you. We walk the property with you, note the condition of each surface, and set honest expectations about what the wash will and will not do. Then we measure every surface we can clean and hand you a line-itemed written estimate with package options, plus a digital copy.

Scheduling and the 30-Minute Heads-Up

Approve the services you want, and we set a specific day, usually within two weeks depending on the season. You get a confirmation with the date, time, services, price, and any prep reminders. On the day, the crew calls about 30 minutes before they arrive.

Scope Review and Pre-Inspection

A two-person team introduces themselves and reviews the scope with you. Our lead tech walks the home for a pre-inspection, and we start photo documentation here. Before any solution touches the house, we protect the plant and property first.

A Soft Wash Matched to Your Exterior

Our SoftWash Systems blend module mixes water, SoftWash soaps, and sodium hypochlorite, dialed to about one percent for a house wash. We set the recipe to your surface and apply it at low pressure from the ground or a ladder. No power washer goes near the home.

The Exterior Gutter Scrub

We clean everything from the gutters down, and we scrub the outside faces of the gutters as part of the wash. We keep your outlets and fixtures protected the whole time.

The Walk-Around With You

When the work is done, we walk the whole home together, and you point out anything you want us to check again. We stand behind the result, and we collect payment after you have seen the finished wash.

How We Price House Washing by Size,
Condition, and Difficulty

Pricing Details

Every home is different, so we provide a custom quote for house washing. We price by square footage, surface material, and the current condition of your exterior, and we set the final price based on your in-person estimate. Here is the range most homes land in.

  • Typically $500-$800 for general-market homes, up to $10,000 or more for luxury and custom properties (custom quote by square footage, condition, and difficulty). The sliding scale reflects the amount of surface area and how much care the finish requires.
  • Combine two or more services and a bundle discount applies, worked out on your estimate.
  • We offer a first-responder discount. Ask about it, and we will apply it to your quote.

Roof to Curb, Your Whole Property Cleaned in One Visit

Roof to Curb is our whole-property package: everything from the roof down to the driveway, cleaned in a single visit. Our crew is on site all day instead of hopping between jobs. That is why this package carries the biggest bundle discount we offer, applied right on your estimate. Package options sit on every estimate we write, so you can take Roof to Curb as it stands or build your own combination.

Maintenance Plans That Include House Washing

Our Maintenance Plans schedule your house washing and the rest of your exterior. We plan the whole year out, so you don’t have to think about it. We customize the cadence to your property and dispatch the crew with about a week’s notice. It is billed as a simple monthly subscription.

  • Our Premier Property Maintenance Plan is a fully customized, year-round plan that keeps your entire property looking its best: windows twice a year, gutters up to quarterly, roof and all surfaces cleaned at least annually, planned out for the whole year.

Our House Washing Guarantee
and 16-Month Vinyl Warranty

Midwest Softwash Guarantee

100% Satisfaction Guarantee

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 get the crew back out as soon as possible, often the same or next day.

16-Month Vinyl Siding Warranty

Our house washing comes with a 16-month warranty on vinyl siding. That coverage applies only to vinyl; we clean other surfaces to the same standard, but without the same written term.

My house and fence look new again. This company is prompt to respond, super professional and friendly, and does top notch work. Would highly recommend.
Response from the owner:Angela, thank you so much! Hearing that your house and fence look new again is exactly what we aim for. We're glad the whole experience felt smooth from start to finish, and we'd love to work with you again anytime!
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!

House Washing
FAQs

Most homes take about 2 to 2.5 hours. The exact time depends on the home’s size and how much growth has built up on the surfaces.

No. A house wash clears organic growth like algae and mildew, while oxidation is a separate restoration. It shows up most on Hardie board and vinyl siding. You cannot lift it from one spot, so we treat the whole wall. We wet it down, let the solution dwell, hand-brush it off (usually over two days), and finish with a wax that slows its return. We can add it alongside your house wash.

We scrub the outside faces of your gutters as part of the wash. We clean out leaves and debris from inside the gutters with our separate gutter cleaning. We remove the debris by hand, bag it, haul it away, and flush the downspouts. You can add it to the same visit, and it counts toward a bundle.

It is not required, though we prefer it. Our crew does a full walk-around with you at the end so you can see the finished work and flag anything you want checked again.

Yes, we use your home’s water. It runs about a cent a gallon, so even a large house wash costs only pennies in water.
