Mold, mildew, and algae settle into composite, vinyl, and wood decks, and our hot, humid summers keep that growth coming back. A deck sitting in shade and moisture is exactly what it feeds on. At MidWest SoftWash, we clean every deck with a gentle soft wash, matching the solution strength to your decking and its condition. Call (636) 244-1024 and we will get that growth off your deck.

Whatever your deck is built from, we soft-wash it and set the solution strength to the surface and how soiled it is. Here is how each one is handled.

Composite gets a straight soft wash. We dial the solution to the boards and how much growth has taken hold, so it cleans without forcing anything onto the surface.

Vinyl gets the same low-pressure treatment. Our solution lifts the growth, not a machine, and we tune the strength to the condition we find on the day.

We soft-wash wood too, and for wood, we clean only. We soft-wash composite and wood decks and fences to clean them beautifully, but we don’t prep for stain or apply stain. If your wood needs staining, we’re honest that we’re not the right fit for that part.

Pool decks get the same gentle treatment, including cool decking. Cool decking can't take a power washer, so soft washing is the only safe way to clean it. We set up plant protection around the pool before we start and move your pool furniture as needed. While we work, we keep debris out of the water. You get a clean deck without anything ending up where it shouldn't.
Here is what you get when you hand your deck to our crew.

We never put a power washer on composite, vinyl, or wood decking. Those surfaces don’t need force, and force is what damages them. The solution does the cleaning, so your deck stays clean and unharmed.

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. That same training stands behind every deck we clean.

Before a drop of solution touches your home, we start with plant and property protection. 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. Your deck sits right next to beds, lawn, and landscaping, and we cover it all.

The solutions we use on your deck are Good Steward Approved, 100% biodegradable, water-based, and phosphate-free. That matters on a deck, because whatever we spray sits a few feet from your lawn, your plants, and often your pool.
From your first call to the final walk-around, here is how a deck cleaning goes.
Reach out by phone, text, or email, and we’ll come to you. We walk the deck with you, note its condition, and set honest expectations about what the clean will do. Then we measure every surface we can help with. A written, line-itemed estimate follows, package options included, with a digital copy for your records.
You approve the services you want, and we set a specific day, typically within two weeks depending on the season. A confirmation email follows with the date, time, services, price, and any prep reminders.
On the day, the crew calls about 30 minutes ahead. A two-person team arrives, introduces themselves, and reviews the scope with you before any work starts.
Protection comes first. We set up plant and property protection before we apply any solution, and we move your deck furniture as needed.
Then we clean. We apply SoftWash Systems soaps with our soft-wash equipment, with the strength set to your boards and their level of soiling. We work the deck in the right order so nothing is missed.
When the deck is done, we walk it with you. We send before-and-after photos, collect payment at the finish, and if anything isn’t right, we fix it on the spot.

We price deck cleaning by your deck’s size and condition. There is no flat rate, so the final price comes from an in-person measurement and your line-item estimate.
A couple of ways to save:

Our Maintenance Plans keep your deck, and the rest of your property, on a cleaning schedule so you don’t have to track it yourself. Each plan is customized to what you want, planned out for the whole year, and billed as a monthly subscription. We dispatch the crew with a week’s notice, and you never have to think about when the deck is due. Ask about our Maintenance Plans when you get your estimate.
Your deck cleaning is covered like every job we do. We stand behind every job with a 100% satisfaction guarantee. If something isn’t right, call us, and a territory manager will review your concerns and send the crew back as soon as possible, often the same or next day.

Most decks take about one to three hours. Deck size and buildup severity affect the time.
Yes. Fence cleaning uses the same soft-wash process and the same pricing basis as deck cleaning, and we clean vinyl, composite, and wood fencing. Adding it to your deck cleaning means two services on one estimate, which qualifies you for bundle savings.
It isn’t required, but we prefer it. We do a full walk-around with you at the end, and meeting in person is a big part of how we work. Being there means you see the finished deck and sign off on it yourself.
