— Why Johnston homes need this
Soft Washing, the Johnston way.
The homes
Johnston runs 1980s–2010s subdivisions for the most part — executive-scale homes with brick fronts, vinyl side and rear, attached three-car garages. The Beaver Creek and Saylorville-adjacent properties trend larger and more wooded.
Some newer lakefront/lake-near homes have wraparound decks and outdoor kitchens that need pressure-wash + soft-wash combinations. Asphalt shingle roofs are universal; few tile, few cedar shake.
On the siding here
Soft washing is the bulk of what we do in Johnston, because the housing is the right age for it. Vinyl siding on the north-facing walls of those 1980s-to-2010s executive homes in Northbrook, Greendale, and Crown Point is the most reliable algae-streak surface around — the black-green film settles into the vinyl side and rear long before the brick fronts ever show it.
The wooded, shaded lots out by Beaver Creek and the Saylorville-adjacent properties streak fastest and heaviest, soffits and fences included. It's all garden-hose pressure plus a biodegradable cleaner that kills the growth at the root, never a blast that would damage the siding. The earliest builds here are now old enough that their north roof slopes are starting to streak, so asphalt shingle algae gets the same gentle soft-wash treatment. A proper wash holds 18 to 24 months.

What central Iowa homeowners are saying.
Real reviews from the families and properties we’ve cared for across central Iowa.
“The crew came and did my windows, the deck, and soft-washed the house — they did a great job. Up-and-coming young company doing good work.”
“Super thorough, prompt, professional — and fantastic work. Our house sparkled when they were finished. I've hired window washers before and was always bummed by streaks the next day. Not so with JBL — everything looked perfect, even after it rained.”
“We used JBL Exterior Pros for a complete exterior soft washing of our home and are extremely happy with the results. The work was completed exactly as promised and on schedule. A team of four arrived promptly, were professional and courteous, and did an exceptional job with minimal disruption.”
“JBL did a fantastic job soft washing our house and deck for a very reasonable price. The dirt had piled up on our siding over the years and I'd tried to clean it myself to no avail. They were upfront, easy to work with — we're having them back for the windows and screens.”
“Amazing job! Our house looks like it got a brand new paint job. The team was so friendly and kind to our family and we are so happy with how it turned out. 10/10 would recommend and will use them again in future years.”
“Tatum was great to work with, and gave our windows a much needed cleaning after winter.”

Soft washing questions, answered.
The things Johnston homeowners ask us most, before the first visit. Don’t see yours? Just ask.
Yes — JBL Exterior Pros covers every Johnston neighborhood and ZIP code (50131, Polk County), from Beaver Creek area, Northbrook, Greendale to Saylorville-adjacent. We're on Johnston streets regularly — only 10 miles from downtown Des Moines.
Pressure washing uses high pressure — right for concrete, brick, and hard surfaces. Soft washing uses low pressure plus a biodegradable cleaner — the only safe method for siding, stucco, painted surfaces, and roofs.
Yes. We use biodegradable, plant-safe cleaners and pre-rinse all landscaping before and after. We'll ask you to keep pets indoors during application.
A proper soft wash kills algae and mildew at the root — most surfaces stay clean 18 to 24 months. Annual members get scheduled re-treatments before re-growth shows.
Soft washing in Johnston is priced by the size of your home and the scope of the job — every Johnston property is a little different. Every quote is free and walked in person within one business day, so the price reflects the actual home, not a flat rate.
Landscape protection is built into the process. We pre-rinse all plants and beds before applying any solution, tarp sensitive species where needed, and rinse again after the job. The cleaning solution is biodegradable and breaks down within hours. Tell us about any species you're particularly concerned about during the walk-through.
Soft washing kills the organic growth (algae, mildew) but won't strip intact paint. For chemical paint removal you'd want a different process. For cedar shake darkening caused by mildew, soft washing usually restores the original color — but heavily weathered cedar may need refinishing afterward.
Pressure washing siding strips paint, damages caulking and seals around windows, and forces water behind the cladding — which can cause hidden rot. Most siding warranties explicitly require soft-wash methods. The pressure that's right for concrete is wrong for vinyl, wood, stucco, fiber cement, and painted surfaces.
There's a mild chlorine odor during application (similar to a freshly-cleaned pool deck) that dissipates within 30–60 minutes. You can be home. Keep windows closed during the work and pets indoors. Outdoor entertaining is fine the same evening.
