Soft washing uses low pressure (under 500 PSI) with biodegradable cleaning solutions to safely remove mold, algae, and dirt from delicate surfaces like siding and roofs. Pressure washing uses high pressure (1,300 to 4,000 PSI) with water alone to clean hard surfaces like driveways and concrete. Most Minneapolis homes need both methods: soft washing for the house and roof, pressure washing for the driveway and walkways.
If you have searched for “pressure washing” to get your Minneapolis home cleaned, you are probably looking at the wrong service for your siding. Pressure washing is the right call for your driveway. For your home’s exterior walls and roof, soft washing is the method that cleans without causing damage.
We use both methods every day across the Twin Cities metro. This guide breaks down exactly when and why we choose each one so you can make an informed decision before hiring anyone.
What Is Soft Washing? (And How It Actually Works)
Soft washing relies on the cleaning solution, not water pressure, to do the heavy lifting. The system operates at under 500 PSI. For roof cleaning, we stay under 100 PSI. The biodegradable detergent breaks down mold, algae, mildew, and dirt at a molecular level, which means it kills organic growth at the root rather than just blasting it off the surface.
Our process starts before any detergent touches your home. We wet down all surrounding plants, flowers, and landscaping with water first. Then we soak one or two sides of the home, depending on how quickly the sun can dry the surface.
After pre-wetting, we apply our detergent using downstream injectors or direct pumps. The detergent dwells on the surface for five to seven minutes. That dwell time is where the actual cleaning happens. Once the solution has broken everything down, we rinse the siding and windows thoroughly with low-pressure water.
We adjust detergent strength based on your siding type. Vinyl and hardy board get our standard concentration. Cedar and stucco require a different mix because those materials react differently to cleaning agents. This is a detail most companies skip, and it is one of the reasons results vary between providers.
After rinsing, we put back anything we moved, run a final inspection around the entire home, and do a walk-around with you to make sure everything meets your expectations. If we are also doing your window cleaning in Minneapolis, we start that after the first washed side has dried.
The results from soft washing typically last one to three years because the detergent kills the organisms causing the buildup. Pressure washing, by comparison, only removes what is on the surface and does nothing to prevent regrowth.
What Is Pressure Washing? (And When to Use It)
Pressure washing pushes water at 1,300 to 4,000+ PSI to blast embedded dirt, grime, and stains off hard surfaces. No cleaning agents are needed for most pressure washing jobs. The force of the water handles the work.
This method is built for durable surfaces: concrete driveways, sidewalks, patios, brick, and stone. These materials can absorb the pressure without cracking, chipping, or losing their finish.
Even on concrete, we do not skip prep work. We apply detergent to the driveway first, then use a surface cleaner to power wash and rinse evenly. Surface cleaners produce a uniform clean without the streaking that a standard pressure washing wand leaves behind.
Pressure washing is not safe for siding, roofs, painted wood, or stucco. The force strips paint, dents vinyl, removes the protective granule layer from roof shingles, and drives water behind surfaces where it causes hidden mold and rot. If a company tells you they pressure wash everything, that is a red flag.
For your driveway and concrete cleaning, pressure washing is the fastest and most effective option. For everything else on your home, soft washing is the safer choice.
Soft Washing vs. Pressure Washing: Side-by-Side Comparison
The quickest way to understand when each method applies is to compare them directly across the factors that matter to homeowners.
| Factor | Soft Washing | Pressure Washing |
| Water Pressure | Under 500 PSI (under 100 PSI for roofs) | 1,300 to 4,000+ PSI |
| Cleaning Agents | Yes, biodegradable detergents | Typically water only |
| Best Surfaces | Siding (vinyl, hardy board, stucco, cedar), roofs, painted wood, decks, fencing | Concrete driveways, sidewalks, patios, brick, stone |
| Damage Risk | Very low when done correctly | High on delicate surfaces. Can strip paint, dent siding, and void roof warranties. |
| How Long Results Last | 1 to 3 years (kills growth at the root) | 6 to 12 months (removes surface dirt only) |
| Cost Range (Minneapolis) | $300 to $800+ for home washing | $199 to $599 for driveway cleaning |
| Best Season in MN | March through November | March through November |
| Environmental Impact | Biodegradable solutions, lower water usage | Water only, higher water usage |
The key difference is not just pressure. Soft washing treats the source of the problem. Pressure washing treats the symptom. Both have their place, but using the wrong one on the wrong surface leads to damage that costs far more than the cleaning itself.
Which Surfaces on Your Minneapolis Home Need Which Method?
A typical Minneapolis-area home has multiple exterior surfaces, and each one calls for a different approach. This table maps every common surface to the correct cleaning method.
| Surface | Recommended Method | Why |
| Vinyl siding | Soft wash | High pressure strips paint and dents vinyl panels. Detergent removes mold and algae safely. |
| Hardy board siding | Soft wash | Same approach as vinyl. Pressure would chip the paint layer. |
| Cedar siding | Soft wash (adjusted detergent) | Cedar is a softer wood that requires careful detergent concentration and an even gentler rinse. |
| Stucco | Soft wash (adjusted detergent) | Pressure blasts holes in stucco. Soft washing cleans the surface without structural damage. |
| Asphalt shingle roof | Soft wash only | ARMA prohibits pressure washing shingles. It removes granules and voids the warranty. |
| Concrete driveway | Pressure wash | Concrete handles high pressure well. Surface cleaners provide even, streak-free results. |
| Concrete sidewalks | Pressure wash | Pressure removes embedded dirt, tire marks, and stains that soft washing cannot reach. |
| Wood deck | Soft wash | Pressure damages wood grain, causing splintering and etching. Detergent does the cleaning work safely. |
| Composite deck | Soft wash | Pressure can scratch composite materials. Low pressure with detergent is the safer approach. |
| Brick or pavers | Depends on condition | Newer brick handles pressure well. Older brick with deteriorating mortar joints needs soft washing. |
| Gutters (exterior) | Soft wash (with house) | Cleaned as part of the home washing service. No separate treatment required. |
If your home has vinyl or hardy board siding (the vast majority of homes across Lakeville, Eagan, Apple Valley, and Burnsville), the answer is soft washing for the house and pressure washing for the concrete. Most homeowners get both done in the same visit.
Why Minneapolis Homes Need Exterior Cleaning More Than You Think
Minneapolis does not go easy on your home’s exterior. The climate here creates ideal conditions for mold, algae, and mildew to take hold and spread.
The city averages 32 inches of rain per year, with the heaviest precipitation falling from June through September. Average humidity sits at 67% annually and regularly spikes above 80% during the summer months. Those moisture levels feed organic growth on every surface of your home.
Winter compounds the problem. Minneapolis averages 45 to 55 inches of snowfall per year and 55 to 60 freeze-thaw cycles per season. That repeated freezing and thawing cracks exterior surfaces at a microscopic level, creating tiny openings where moisture gets trapped and organic growth takes root. By spring, the buildup that started the previous summer has had months of moisture contact to entrench itself.
Established neighborhoods with mature tree canopy, common across the south metro suburbs, add another layer. Trees provide shade and retain moisture around your home, which accelerates mold and algae growth on siding and roofs.
The Minnesota Department of Health recommends keeping humidity under 60% to prevent mold growth. Minneapolis regularly exceeds that threshold outdoors for months at a time, which is why annual exterior cleaning is not optional maintenance here. It is preventative care.
Many Minneapolis suburbs also have HOA communities that enforce exterior appearance standards. Dirty siding, stained driveways, and streaked roofs trigger violation notices and fines. Annual exterior cleaning keeps your property compliant and saves you from those conversations with the board.
The median home value in Minneapolis sits between $339,000 and $365,000 in 2026. Industry data shows curb appeal improvements raise perceived property value by 5% to 7%. On a $340,000 home, that translates to $17,000 to $24,000 in perceived value from a service that costs a few hundred dollars. Homes with clean, well-maintained exteriors also tend to sell faster because buyer impressions form within seconds of pulling into the driveway.
What Does Exterior Cleaning Cost in Minneapolis?
Pricing varies by the size of your home, the type of siding, the level of buildup, and which services you combine. We use a size-based pricing structure (small, medium, large, XL, XXL) rather than charging per square foot, which makes it easier to get an accurate quote quickly.
| Service | Method Used | Typical Minneapolis Price Range | Time to Complete |
| Home washing (vinyl/hardy board) | Soft wash | $300 to $800+ | 1 to 3 hours |
| Home washing (cedar/stucco) | Soft wash | Higher due to siding complexity | 2 to 4 hours |
| Roof cleaning (asphalt shingle) | Soft wash | $500 to $3,000 | About 3 hours |
| Driveway cleaning (concrete) | Pressure wash | $199 to $599 | 1 to 3 hours |
| Deck cleaning | Soft wash | $99 to $599 | 30 min to 3 hours |
| Gutter cleaning | Hand clean + flush | $129 to $359 | 30 min to 3 hours |
| Window cleaning | Water-fed pole / squeegee | $179 to $999 | 45 min to 10 hours |
Combining services saves money. Soft wash the home and pressure wash the driveway in one visit, and you avoid paying for two separate mobilizations. We also offer bundle pricing when you combine home washing with window cleaning. Neighborhood discounts of 10% to 20% are available when multiple homeowners on the same street book together.

Can You Pressure Wash a Roof? (Why the Answer Is Always No)
The Asphalt Roofing Manufacturers Association (ARMA) explicitly prohibits pressure washing on asphalt shingle roofs. Pressure above 300 PSI removes the granule layer that protects your shingles from UV degradation. That damage voids most manufacturer warranties and shortens the life of your roof by years.
Soft washing is the only approved method for asphalt shingle roofs. The process uses low-pressure application of a cleaning solution that kills moss, algae, and lichen without disturbing the shingle surface.
Our roof cleaning process starts with protecting your property. We spray all vegetation, landscaping, and the home’s siding with water before any detergent goes on the roof. Then we apply our cleaning solution to the roof surface and let it dwell. We typically apply a second coat to ensure full coverage. While the detergent is working, we keep all surrounding areas wet to prevent any runoff damage.
If your gutter downspouts drain near plants or landscaping, we divert them away from those areas during the cleaning.
We warranty our roof cleaning for three years against mold and algae regrowth. If anything reappears within that period, we come back and spot-treat it at no charge. Industry guidance from the Roof Cleaning Institute of America suggests that professional soft washing can keep a roof clean for two to five years depending on tree coverage and shade exposure.
How to Choose the Right Exterior Cleaning Company in Minneapolis
Not every company that calls itself a pressure washing service understands the difference between these methods. Before you hire anyone, ask these questions:
Do you soft wash or only pressure wash?
A company that uses high pressure on everything, including siding and roofs, does not understand the surfaces they are cleaning. Ask specifically about their PSI range for home exteriors.
Are you fully insured with liability and workers’ comp?
Both coverages matter. Liability insurance covers damage to your property. Workers’ comp covers their crew if someone gets injured on your property. We carry $1 million in liability insurance along with full workers’ compensation coverage.
What detergents do you use? Are they safe for plants and pets?
Professional soft wash solutions are biodegradable and designed to be safe for landscaping when applied correctly. Ask how they protect your plants during the process.
Do you offer a satisfaction guarantee?
Any company confident in their work should stand behind it. We offer a 100% satisfaction guarantee on every service, and our technicians do a walk-around with you before they leave to make sure everything looks right.
Can you adjust your process for different siding types?
Vinyl, hardy board, cedar, and stucco each require different detergent concentrations. A company that uses the same approach on every surface is cutting corners.
We have been in the exterior cleaning business for over 16 years and are among the highest-reviewed companies in Minnesota with a 4.9+ star rating. We are members of the Window Cleaning Resource Association and Pressure Washing Resource Association.

Frequently Asked Questions
Does soft washing use chemicals that could harm my plants or pets?
Professional soft wash solutions are biodegradable and formulated to be safe for landscaping and pets when applied correctly. We pre-wet all plants, flowers, and surrounding surfaces with water before applying any detergent, creating a barrier that dilutes contact to safe levels. By the time we finish rinsing, the solution is diluted down to nearly nothing.
How long do soft washing results last compared to pressure washing?
Timing depends on your property’s exposure. A home surrounded by mature trees in Lakeville will see regrowth faster than a home on an open lot in Burnsville. Tree canopy traps moisture and drops organic debris onto your roof and siding, which speeds up the cycle. We recommend annual soft washing for heavily wooded properties and every two years for homes with less tree coverage.
Can I pressure wash my own house with a rented machine?
Consumer-grade pressure washers from hardware stores typically produce 2,000 to 3,000 PSI, which is more than enough to damage vinyl siding, strip paint, and force water behind your siding where it causes hidden mold and rot. Soft washing requires specialized equipment and professional-grade biodegradable detergents that are not available at retail stores. The risk of DIY damage to your home far exceeds the cost of hiring a professional.
Should I clean my gutters before or after washing my house?
Clean your gutters first. Gutter debris contains decomposing organic material that can stain freshly cleaned siding if it overflows during the next rain. We offer gutter cleaning as a standalone service or bundled with home washing for a combined discount.
Is soft washing the same as low-pressure washing?
They are related but not the same thing. Low-pressure washing simply reduces the PSI setting on a pressure washer. Soft washing is a distinct method that combines low pressure with specialized biodegradable detergents designed to kill organic growth at a molecular level. The cleaning solution is what makes soft washing effective. Reducing pressure alone, without the right detergent, produces weaker results.
