HOA Exterior Cleaning for Algae
on North-Facing Siding

Exterior Cleaning for HOAs in St. Charles County MO

Algae and other organic growth build up on the north-facing siding of the buildings in your community. Hot, humid summers and cold winters feed that growth year-round. Our HOA exterior cleaning at MidWest SoftWash uses the same low-pressure soft wash we use on homes. We scale it up for a property full of buildings. Call (636) 244-1024 and we’ll get the growth off your community’s siding.

Whole-Wall Oxidation Restoration on Hardie Board and Vinyl

When the siding across your community has gone chalky, that is oxidation, and it is a restoration, not a routine wash. HOAs add it to their cleaning often, and it shows up most on Hardie Board and vinyl siding. You can't lift oxidation from one spot, so we treat the whole wall. We wet it down, apply our solutions, let them dwell, then hand-brush the oxidation off. It usually takes two days, since the second day catches what only shows once the surface dries. We finish with a wax UV-inhibitor application to slow its return.

Why HOA Property Managers Choose Us
for Multi-Week Washes

Property managers hand us the whole community for a few plain reasons.

Built for HOA Projects That Run Two Weeks

We’ve run washes that lasted two full weeks, building after building, without dropping the level of care from the first to the last. A community full of buildings is a normal day for our team, not a stretch of it.

The Insurance Your Board Asks For

We carry auto, general liability, workers’ compensation, and umbrella coverage. That is the insurance profile boards and property managers ask to see before anyone touches the property, and we have it ready when you request it.

Updates on the Schedule You Choose

You tell us how often you want to hear from us: daily, weekly, or somewhere in between. We keep you updated on that cadence through the whole job, so there’s no chasing us for a status.

A True Soft Wash With No Power Washer

We’re one of the only companies around that performs a true soft wash: low pressure, professional cleaning solutions, and no power washer touching your buildings. Many companies call it a soft wash but still reach for a pressure washer. We don’t.

HOA Exterior Cleaning Walkthrough

How an HOA Wash Moves
From Scope to Photo Report

Here is how an HOA wash goes with our team, from the first walkthrough to the finished photo report.

The Walkthrough and Written Scope

Reach out by call, text, or email, and we come out to walk the property. We measure every building and surface we can help with, then put it all on a written, line-itemed estimate with a digital copy for your records. We respond to RFPs and work straight from a written scope of work when your board uses one.

Contract, Insurance Certificate, and W-9

Before any work starts, we get you the certificate of insurance, a W-9, and a signed contract or MSA. We handle your paperwork the way boards and management companies need it.

Scheduling the Community

Once you approve the scope, we set specific dates, usually within two weeks depending on the season. You get a confirmation covering the dates, the services, and any prep reminders.

Plant and Property Protection

On arrival, the crew reviews the scope and starts with plant and property protection. We shield landscaping, cover outlets, and protect the property before we apply any solution, and the lead tech walks the property first.

The Soft Wash, Building by Building

We dial the SoftWash Systems blend module to each surface and apply our SoftWash soaps, giving every material its own soap recipe. We clean from the gutters and fascia down, including an exterior gutter scrub, using ladders and harnesses when rooftop access is needed. No power washer goes on your buildings.

The Plant-Wash Finish

To finish, we treat delicate landscaping with our plant-wash solution, which feeds the soil the plants grow in rather than just rinsing them.

Walk-Around, Photo Report, and Invoice

At the end, we walk the finished work with you and send timestamped photos from the pre-inspection, during, and after via a photo link. Commercial invoicing is typically net-30, and we send the invoice after you’re satisfied with the job.

Per-Unit Pricing
for Every Building in Your HOA

Pricing Details

We price HOA work per unit, with the final number set once we’ve walked the property and seen the buildings.

  • HOA exterior wash, per unit. We quote HOA washes per unit as a custom commercial quote, so the price tracks the actual community. Large single buildings like a clubhouse or amenity building can be quoted by square footage instead. Either way, the figure is set after the walkthrough.
  • Oxidation restoration add-on. Priced by the square foot as a restoration service; approximately $0.55 per square foot. Because oxidation must be treated across the whole wall, the square footage covers full surfaces, not spots.

Maintenance Plans That Keep Your HOA on Schedule

Your community doesn’t have to call us building by building, year after year. We build Maintenance Plans around the property, with scheduled dates set in advance, so upkeep happens automatically. Ask about our maintenance plans when you get your estimate.

  • Commercial Maintenance Plan. Recurring commercial maintenance on an annual, semi-annual, or custom cadence built around your property, with the communication cadence your property manager needs.

Our Promise to Send
the Crew Back Out

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. That covers every building on the contract, not just the ones out front.

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!

Questions HOAs Ask
Before We Start

It can run from part of a day to multiple weeks, depending on the community. The number and size of the buildings set the timeline, so a small subdivision and a large, multi-building community are very different jobs.

No. We use your water on site, and it runs about a cent a gallon, so even a large job costs just pennies in water. For reference, a 25,000-square-foot building used under three dollars of water.

Yes, where the community wants it, individual homeowners can add services like window, deck, or patio cleaning on separate, homeowner-paid dates. Window cleaning is exterior only, done with a water-fed pole.

Generally no. We coordinate access and scheduling with your property manager, so the work moves through the community without each homeowner needing to be present.
