We recommend house washing every 1–2 years in Montana. Our climate promotes algae and mildew growth, especially on north-facing walls. Annual washing keeps your home protected and looking great year-round.
Our process removes the vast majority of biological staining (algae, mold, mildew), dirt, and oxidation. Some deep rust stains or paint discoloration may require additional treatment. We'll assess this during your free quote.
You don't need to be present, but we do ask that pets are secured and windows are closed. We'll reach out before and after the job so you're always in the loop.
Most residential house washing jobs take 2–4 hours depending on home size. Larger homes with heavy staining may take longer. We'll give you a time estimate when you book.
Many customers bundle house washing with other services for a complete property refresh. Ask us about package pricing when you request your quote.

Your home's exterior is constantly under attack from Montana's brutal weather. From the scorching summer UV that bleaches and oxidizes siding, to the heavy spring rains that promote mold and algae growth, to the ice and snow that leaves mineral deposits and staining — the exterior of your Montana home takes more punishment than most homeowners realize. Professional house washing by 406 Pressure Clean is the most effective way to restore your home's appearance and protect the investment you've made in your property.
We use a soft wash system for house washing — not high-pressure blasting. High pressure on siding is one of the most common mistakes DIY pressure washers make. Too much pressure drives water up behind siding panels, saturates insulation, damages caulking around windows and doors, and can even strip paint or dent aluminum siding. Our soft wash approach uses low pressure combined with professional-grade biodegradable cleaning solutions that kill mold, algae and mildew at the root rather than just blasting the surface.
The results speak for themselves. Most homes in Eastern Montana that haven't been professionally washed in 2+ years have significant biological growth on north-facing walls, in shaded areas, and around the roofline. Green algae, black streaks from roof runoff, and spider webs embedded in the siding are extremely common. After a professional soft wash, these all disappear — and most customers tell us their home looks better than the day they moved in.
House washing prices in Montana vary based on the size of the home, number of stories, siding type and level of buildup. A standard single-story home in Billings typically runs $200-$350. Two-story homes run $300-$450. We price per job, not per hour, so you know the cost upfront with no surprises. Call or fill out our quote form and we'll get back to you within 24 hours with a firm price.
When you factor in the cost of repainting a home exterior — which runs $3,000-$10,000 or more in Montana — regular house washing at a few hundred dollars every couple of years is one of the best ROI home maintenance investments you can make. Clean siding lasts longer, holds paint better, and prevents the kind of moisture damage that leads to costly repairs down the road.
We provide professional house washing services throughout Eastern Montana including Billings, Miles City, Glendive, Forsyth, Sidney, Colstrip, Hardin, Laurel and Lewistown. Billings is our home base with same-week availability in most cases. We serve both residential homeowners and property management companies with multi-unit residential properties.
Is soft washing safe for all siding types? Yes — soft washing is safe for vinyl siding, wood siding, fiber cement (Hardie board), stucco, brick and painted surfaces. We adjust our solution and technique based on your specific siding material.
How long does house washing take? Most single-story homes take 2-3 hours. Two-story homes take 3-5 hours. We work efficiently and leave your property clean — no mess, no residue left behind.
Do I need to be home during the wash? Not necessarily — we just need access to an outdoor spigot and any gates to fenced areas. Many customers leave us a note and go about their day.
How often should I wash my house exterior in Montana? We recommend every 1-2 years. Homes near trees, in humid low-lying areas, or with north-facing walls that stay shaded benefit most from annual washing.
House washing is the single highest-impact exterior cleaning service for Montana homeowners. The exterior siding of your home is its first line of defense against Montana's weather — and it's the first thing people see. Mold, algae, mildew and oxidation on siding don't just look bad, they actively attack the material and the paint underneath. Regular professional house washing preserves your home's appearance, protects its structure and maintains its value.
We soft wash every home we clean. Soft washing is fundamentally different from pressure washing for house exteriors. While pressure washing uses high-force water to physically blast dirt off surfaces, soft washing uses a low-pressure application of professional cleaning solution that penetrates and chemically dissolves biological growth. The key difference is what happens to the mold and algae — pressure washing removes it from the surface but leaves the root structure in the material, meaning it grows back faster. Soft washing kills it completely at the source, and results last significantly longer as a result.
Vinyl Siding: The most common siding type in Eastern Montana. Vinyl is durable but susceptible to algae and mildew staining, particularly on north-facing walls and under roof overhangs where moisture accumulates. Soft washing vinyl restores the original color without damaging the material or driving water behind panels.
Wood and Fiber Cement Siding: Wood and Hardie board fiber cement siding requires careful soft washing that cleans thoroughly without saturating the material. We use appropriate cleaning solutions and controlled pressure to avoid moisture infiltration behind siding boards.
Brick and Stucco: Brick and stucco homes in Montana accumulate efflorescence — white mineral deposits — as well as the standard biological growth. We use specific efflorescence treatment and appropriate pressure for masonry surfaces that won't damage mortar joints or stucco finish coatings.
Aluminum and Metal Panel Siding: Older Montana homes with aluminum siding and modern metal panel commercial buildings both benefit from soft washing that removes oxidation and chalking. We use appropriate cleaning chemistry for metal that doesn't cause streaking or surface reactions.
Our standard house washing service covers all exterior siding surfaces, eaves and soffits, exterior trim, window frames and ledges, visible foundation, front porch and entry areas, and accessible facia boards. We pre-wet all landscaping around the home and rinse thoroughly after cleaning to protect your plants, lawn and flower beds from cleaning solution.
Many Montana homeowners skip house washing as a "nice to have" expense. But the cost of not washing accumulates in ways that aren't always obvious until they become expensive. Mold embedded in siding works its way into joints and behind panels over time, eventually requiring siding replacement. Paint on wood trim that's constantly wet from biological growth blisters, peels and fails years earlier than it should, requiring costly repainting. Biological growth on soffits and eaves attracts insects and moisture, creating conditions for pest infestation and wood rot in the roof structure.
The economics are straightforward — professional house washing every 1-2 years costs a few hundred dollars. Siding replacement on a typical Montana home costs $8,000-$25,000. Exterior repainting costs $3,000-$12,000. Roof soffit and fascia repair from moisture damage runs $1,000-$5,000. Regular washing is genuine preventive maintenance with exceptional return on investment.
To prepare for your house washing appointment, close all windows and doors, move outdoor furniture and potted plants away from the home's perimeter if possible, and ensure we have access to an outdoor water spigot. If you have a particularly delicate garden bed directly against the foundation, let us know and we'll take extra precautions. That's really all that's needed — most customers go about their day while we work.
We wash houses spring through fall in Montana. The ideal time for house washing is late spring after cottonwood season and pollen have settled, or early fall before freezing temperatures arrive. We avoid house washing when overnight temperatures are forecast to drop below freezing, as cleaning solution residue can cause ice formation on surfaces. Summer is our busiest season for house washing — book early to secure your preferred date.
