| Quick Answer |
| Soft washing uses low-pressure cleaning solutions to safely remove algae, mold, and mildew from delicate surfaces such as vinyl siding and asphalt roofs. Pressure washing uses high-pressure water to clean durable surfaces like concrete driveways, sidewalks, and patios. Most homes in Macomb County need both methods, applied to the right surfaces. |
By mid-April, every Macomb County driveway tells the same story. Five months of road salt, snowmelt, and grit have left the concrete stained and grimy, while the north-facing side of the house has turned that familiar shade of green.
The question we hear every spring: “Can I just pressure wash everything?”
The honest answer is no. Using the wrong method doesn’t just give you average results. It can strip the granules off your roof shingles, force water behind your siding, or etch your concrete in ways that can’t be undone.
“A lot of homeowners think everything can just be pressure-washed,” says Zach, owner of Pristine Power Washing. “But that’s where damage happens if you’re not careful.”
This guide breaks down when each method applies, what happens if you choose the wrong one, and how we decide which approach is right for every surface. If you want to know how often to clean each season, our guide on how often to power wash in Macomb County covers that in detail.
The Quick Answer for Macomb County Homeowners
Soft washing is for surfaces that hold organic growth and can be damaged by force: siding, roofs, painted wood, and areas under eaves. Pressure washing is for durable flatwork that needs mechanical force to clean: concrete driveways, sidewalks, patios, and garage aprons.
The real question isn’t “soft wash vs. pressure wash.” It’s which method belongs on each surface. For most homes in Macomb County, the answer is both.
Why This Decision Matters More in Macomb County
Southeast Michigan’s snow season runs from mid-November through early April. That’s roughly five months of road salt, sand, and grime accumulating on every hard surface outside your home.
Macomb County’s tree-shaded neighborhoods also create ideal conditions for the growth of algae and mildew. The green buildup that appears on north-facing vinyl walls every spring isn’t just a cosmetic problem. It’s a biological one, and blasting it off with high pressure only removes what you can see. The spores stay behind.
There’s also an environmental angle most homeowners don’t think about. Macomb County Public Works manages 475 county drains that carry stormwater into local waterways and ultimately into Lake St. Clair. The Clinton River watershed, which covers 760 square miles and more than a thousand miles of streams, runs through most of the county. The cleaning solutions used on your property, and the runoff they create, are not abstract environmental concerns here.
We hold a State of Michigan wastewater management certification. That means every job we run handles runoff properly, keeping it out of the storm-drain system that connects to Lake St. Clair. Not every contractor in the area does this.
Some subdivisions in Shelby Township and Macomb Township also carry HOA appearance requirements, and Clinton Township has a formal complaint process through its Building Department for exterior property conditions. In many neighborhoods in this county, exterior maintenance isn’t optional.
What Is Soft Washing? (And Why It’s Right for Most Home Surfaces)
Soft washing cleans at under 100 PSI. That’s roughly the same pressure as a garden hose. The cleaning isn’t done by force. It’s done by the solution.
We apply a cleaning solution blend that safely removes organic growth, dirt, and debris, let it dwell, and then rinse it away. Because the solution treats the biology rather than blasting the visible layer, surfaces stay cleaner for longer. Algae and mildew that are physically removed without treatment return within a season. Soft-washed surfaces don’t.
Best surfaces for soft washing on Macomb County homes:
- Vinyl siding (roughly half the homes in the county)
- Asphalt shingle roofs
- Painted wood trim and fascia
- Areas under eaves and porch enclosures
- Soffit and fascia
CertainTeed, one of the largest vinyl siding manufacturers, notes that mildew tends to develop in areas that receive little rainfall, such as under eaves and in porch enclosures, and recommends annual cleaning to prevent buildup. That’s exactly what we see on local homes every spring.
The solutions we use are diluted to the point where they won’t harm your landscaping or plants. We pre-wet all vegetation before applying anything, and the rinse that follows is essentially just water. “I’ve never killed anything out of the thousands of houses I’ve washed,” says Zach. The same holds for pets.
For roofs, we follow the cleaning procedures set by ARMA, the Asphalt Roofing Manufacturers Association. More on why that matters in the section below.
One thing people always ask: Do we need a ladder to reach the second story? No. We use specialty shooter tips that let us stand on the ground and reach up to four stories. Most residential jobs don’t require a ladder.

What Is Pressure Washing?
Pressure washing uses high-pressure water, typically 1,500 to 4,000+ PSI, to blast embedded dirt, salt, and grime off hard surfaces. It’s the right tool when the surface can handle force, and the problem is physical buildup rather than biological growth.
We run a commercial 10 GPM unit, which delivers significantly more volume than most residential equipment. For driveways, we use a surface cleaner attachment, a disc with a spinning spray bar inside that maintains a fixed distance from the surface. It produces an even, streak-free clean across the whole driveway rather than the visible wand lines you sometimes see with a basic setup.
Best surfaces for pressure washing in Macomb County:
- Concrete driveways (the most common surface we clean)
- Sidewalks and walkways
- Patios
- Garage aprons
- Brick pavers (at the appropriate PSI)
Our driveway process: pre-soak the surface to open the pores, clean with the surface cleaner, then post-treat with a solution that inhibits organic regrowth. That last step is what keeps the concrete looking clean through the season rather than greening back up by June.
One honest limitation worth mentioning upfront: oil stains. We can treat them, but deep staining may not fully disappear. Oil soaks into concrete over time, and the best-case result for a stain that’s been there for years is that it lightens to a faint shadow. We’d rather tell you that before we start than let you expect a result we can’t deliver.
Soft Washing vs. Pressure Washing
| Method | Pressure | Primary Agent | Best Surfaces | Common Macomb County Use | Risk If Misused |
| Soft Wash | Under 100 PSI | Cleaning solution | Vinyl siding, asphalt shingles, painted wood, eaves, fascia | Spring algae and mildew on siding; annual roof cleaning | Harm to untreated vegetation if plants aren’t pre-wetted |
| Pressure Wash | 1,500–4,000+ PSI | Water force | Concrete driveways, brick pavers, patios, sidewalks, garage aprons | Post-winter salt and grime removal on flatwork | Etched concrete, stripped paint, damaged mortar if PSI is wrong for the surface |
Quick surface guide:
Vinyl siding: soft wash. Asphalt shingle roof: soft wash. Concrete driveway: pressure wash. Brick patio: pressure wash. Painted wood trim: soft wash. Sidewalks: pressure wash. Soffit and fascia: soft wash.
The method also depends on what’s causing the stain, not just what surface it’s on.
Organic growth, such as algae, mildew, and black streaks on roofs, responds to soft washing because the solution treats the underlying biology. Mineral deposits such as rust and efflorescence, and oil-based staining on driveways, may require specialized treatment or a targeted approach.
Treating the wrong stain type with the wrong method is just as costly as choosing the wrong pressure for the surface. In Macomb County, the most common stain types we deal with are: salt and grit on concrete after winter, algae and mildew on north-facing vinyl siding, and organic growth on shingle roofs in tree-shaded neighborhoods.
What Happens If You Use the Wrong Method?
This is the section that most competitor articles either skip or keep vague. Here’s what actually happens.
Pressure washing a roof. This is the most damaging mistake we see, and the one that costs homeowners the most in the long run. High-pressure washing strips the granules off asphalt shingles, shortens the roof’s lifespan, and can void the manufacturer’s warranty. Some contractors brush the moss off instead, which causes the same damage by a different method.
The Asphalt Roofing Manufacturers Association (ARMA) is direct about this: high-pressure washing systems are likely to damage asphalt roofing. Soft washing is the only method they endorse for algae-stained shingles. When we clean a roof, we follow that standard exactly.
| Pressure washing your asphalt roof can void its manufacturer’s warranty. ARMA, the Asphalt Roofing Manufacturers Association, states that high-pressure washing is likely to damage asphalt roofing. Soft washing is the only ARMA-endorsed cleaning method for algae-stained shingles. |
Pressure washing vinyl siding. High pressure can force water behind the siding and into the wall cavity. That water doesn’t drain easily. It sits against the sheathing, creates conditions for mold growth, and eventually causes structural issues. None of that is visible until the damage is already done.
Over-pressuring concrete. Too much PSI etches the surface, creating micro-pitting that traps more dirt going forward. Once concrete is etched, it can’t be smoothed back out.
Soft washing concrete. The solution alone doesn’t lift years of salt staining and embedded grime. Concrete needs mechanical force. Soft washing a driveway is not the same as cleaning it.
“A lot of people think they’re saving money,” Zach says. “But they end up causing damage that costs more to fix later.”
For details on how we handle roof cleaning specifically, see our roof cleaning service page.
Why Most Macomb County Homes Need Both Methods
The better question isn’t “should I soft wash or pressure wash?” It’s “which method belongs where on my property?”
A standard full-service visit from us might include soft washing the siding and roof, and power washing the driveway, walkways, and patio in a single trip. Those are different surfaces with different tolerances and different types of buildup. They don’t get cleaned the same way.
How Pristine Power Washing Evaluates Every Job Before We Arrive
Most of our customers are surprised by this part. We don’t call you to ask questions and then figure out a price on the fly. We research the property first.
When a homeowner submits a request, we look up the address on Google Earth and Street View, measure the square footage of the surfaces involved, and calculate the cost before we pick up the phone. By the time we call, the estimate is already drafted and ready to send.
When we call, it usually sounds something like this: “I’ve already taken the liberty of doing a little bit of research, looking up your home, and I have everything you requested. I just sent that estimate over to you through text and email.”
We hear a lot of “wow, I just filled that out an hour ago.”
On service day, if you’re home, we do a walk-around together before we start. Customers point out the spots they’re most concerned about. Our answer is always the same: yes, we’ll focus on that, because we’re cleaning the whole thing anyway.
Before we begin, we give you one reminder: close your windows and “pretend like you’re in a car wash inside your house.”
When we’re finished, we walk the perimeter with you before we accept a single dollar. “You’re not going to pay until you’re 100% happy” is how every job ends, not a tagline on a website.

What It Costs: Typical Pricing in Macomb County
Pricing depends on surface size, material, degree of buildup, and accessibility. Here are the ranges we typically work within on residential jobs in this area.
[Suggested visual: Pricing table as shown below]
| Service | Typical Range | Notes |
| House Washing (soft wash) | $250 – $750 | Average is $300–$400 for most homes. Minimum job is $250. |
| Roof Cleaning (soft wash) | $300 – $1,000 | Size and pitch are the main factors. Steeper pitch means more square footage and more repositioning. |
| Gutter Cleaning | $200 – $500 | Priced by linear footage and number of stories. Debris is removed and taken off the property. |
| Driveway Cleaning (pressure wash) | $250 – $1,000 | Varies by driveway size. Oil stain treatment is an add-on. |
| Paver Sealing (clean + sand + seal) | $1,500 – $5,000 | Three-day process: clean, polymer sand the joints, seal. Our highest-value service. |
| Multi-service (bundled) | Discount available | Combining services on the same visit lowers the per-service cost. |
In higher-value parts of the county, Shelby Township, Washington Township, and Macomb Township, where home values average between $390,000 and $460,000, a $350 house wash is a small fraction of the investment being maintained.
All estimates are sent before we arrive. Payment is collected only after the final walk-through.
When Should You Schedule Cleaning in Macomb County?
Southeast Michigan’s snow season runs from mid-November through early April. Every exterior surface spends about five months accumulating salt, grit, and grime before the weather breaks. Here’s the maintenance schedule we recommend for most homes in the area.
| Service | Best Season | Recommended Frequency | Why |
| House Washing | Spring (ideal) | Yearly | Clears winter buildup and sets up curb appeal for the full season. |
| Gutter Cleaning | Spring + Fall | Twice per year | Fall clears leaves before the freeze. Spring clears winter debris before rain season. |
| Roof Cleaning | Spring or Fall | Every 1–3 years | Cooler temps are easier to work in. Organic growth cycles with the seasons. |
| Driveway and Concrete | Spring | Yearly | Removes road salt and winter grime before it compounds through the summer. |
| Paver Sealing | Spring or Fall | Every 2–4 years | Surface must be completely dry. Avoid high humidity and frost windows. |
One additional note for shaded lots: north-facing walls and surfaces under heavy tree coverage stay damp longer and grow back faster. In those areas, plan on annual soft washing even if sun-exposed walls on the same property can go two or three years between treatments.
Frequently Asked Questions
Will the cleaning solutions harm my plants, lawn, or garden?
No. The solutions we use are diluted to levels well below any that would harm vegetation, even with direct contact. We pre-wet all plants and surrounding landscaping before applying anything, and the rinse that follows is essentially just water.
The one situation where we exercise extra caution is roof cleaning, where the concentration runs slightly higher and overspray can travel. In those cases, we water down the vegetation around the foundation and manage the runoff at the downspouts before it can spread. In the thousands of homes we’ve washed in Macomb County, we’ve never damaged a plant.
Can pressure washing damage my concrete driveway?
Yes, if the wrong technique is used. Holding a wand too close or using excessive pressure etches the surface, creating small pits that trap more dirt over time. That’s why we use a surface cleaner attachment on every driveway job. The spinning spray bar stays at a consistent distance from the concrete and delivers an even, clean finish without wand lines.
For oil stains specifically, we can treat them, but stains that have been soaking in for years may not fully disappear. The realistic expectation for a long-set oil stain is that it lightens to a faint shadow. We will tell you this before we start, not after.
Will pressure washing damage my roof?
Yes. Pressure washing strips the protective granules from asphalt shingles, reduces their lifespan, and can void the manufacturer’s warranty. Scrubbing moss off with a brush causes the same damage. Both methods remove what you can see while doing harm underneath.
ARMA is explicit: high-pressure washing is likely to damage asphalt roofing. We follow their guidelines on every roof job. Soft washing only, no brushing, no shortcuts.
Do I need to be home when you come out?
No. Most of our customers are at work or out for the day when we arrive. We complete the job and send a text when we’re done.
If you are home, we offer a walk-around at the start and another at the finish before payment. Either way, the result is the same.
How often should I have my home cleaned in Macomb County?
House washing once per year, with spring as the best window. Gutters twice per year, spring and fall. Roof cleaning every one to three years, depending on shade and tree coverage. Concrete and driveways every spring to clear what winter leaves behind.
If your home sits on a shaded lot or has a north-facing wall that stays damp, plan on annual soft washing for those surfaces. They grow back faster than walls that get regular sun.
Are you licensed and insured?
We carry $1 to $2 million in general liability insurance. There is no state-issued pressure washing license in Michigan, but full insurance coverage means your property is protected if anything unexpected happens on the job.
We also hold a State of Michigan wastewater management certification. That means cleaning solution runoff is properly handled on every job and kept out of the storm drains that connect to Lake St. Clair.
What stains won’t fully come off with soft washing or pressure washing?
Some staining requires specialty treatment or may only partially improve regardless of the method used. Deep rust, heavy oxidation on painted surfaces, and long-set oil that has penetrated into concrete all fall into this category.
For oil stains on driveways, we’re direct about expectations: we can lighten them significantly, but a faint shadow is often the best honest outcome for stains that have been there for years. A contractor who tells you otherwise before seeing the stain is overpromising.
What should I look for before hiring a pressure washing company?
Ask whether they carry liability insurance. Ask whether they follow ARMA guidelines for roof cleaning. Ask whether a written estimate is provided before any work begins. Ask whether payment is due before or after the final walk-through.
A contractor who can’t clearly answer the first two questions is taking on risk with your property, not their own. All four of those answers should come easily from any company you’re considering hiring.
