Soft Washing in Portage, WI
Our signature low-pressure soft wash safely sanitizes and rejuvenates your Portage home, eliminating the stubborn moss, river-born algae, and lichen that thrive in the Columbia County climate. We carefully treat siding, stucco, and fences—whether you’re located near the breezy shores of Silver Lake or the wooded lots by Pauquette Park—ensuring a deep clean without the risk of high-pressure damage. It’s the ideal solution for protecting the integrity of our local architecture while restoring that crisp, "just-painted" look to your property.
Pressure Washing in Portage, WI
For heavy-duty masonry and flatwork that can withstand a rigorous blast—like the salt-stained driveways near Swan Lake, the limestone accents of Highway 16 commercial strips, or the weathered patios over by Woodridge Park—our high-intensity pressure washing yields a transformative deep-clean. We strip away decades of embedded mud, tire marks, and industrial soot from aggregate and blockwork throughout Columbia County. Whether you're reclaiming a greasy shop floor near the railroad tracks or scouring the grime off a retail plaza on New Pinery Road, we apply the necessary force to reveal the original stone and concrete hidden beneath the grit.
Roof Washing in Portage, WI
Those unsightly dark stains creeping across your roof aren't just dirt; they’re an aggressive algae called Gloeocapsa magma that literally feeds on your shingles. For homeowners from the quiet subdivisions near Collipp-Worden Park to the historic rooftops overlooking the Fox River, our specialized soft wash system is the cure. We chemically neutralize moss, lichen, and organic infestations at the source, preventing premature decay and sky-high replacement costs. Whether you’ve got a modern build out by Divine Savior or a classic saltbox near MacFarlane Road, our process is 100% safe for all roofing materials, stripping away the grime while preserving the structural integrity of your Columbia County home.
Driveway Cleaning in Portage, WI
Splotchy oil drips, rubber scuffs, irrigation rust, and slick green film can make even the nicest Columbia County property look run-down. Our high-performance surface cleaning pulls deeply embedded contaminants from concrete pads and asphalt runs, whether you're parked near the Fairgrounds or have a long approach off Highway 33. By purging the buildup from your entryways and parking areas, we restore a polished, consistent finish that immediately elevates the curb appeal of your entire lot. From the busy transit corridors of New Pinery Road to the tucked-away cul-de-sacs near Sanborn Park, we make sure your first impression is a spotless one.
Deck Cleaning in Portage, WI
Our brutal Midwest seasons take a heavy toll on outdoor living spaces throughout Columbia County. Between the humid summer stretches near Swan Lake and the damp snowmelt in the spring, wood and composite surfaces quickly succumb to slippery green spores and that dull, ashen weathering.
Our deck restoration process is tailored to the specific boards you’re walking on—whether it's a wraparound porch near Agency House Road or a modern composite build overlooking the Wisconsin River levee. We balance specialized eco-friendly treatments with the exact flow needed to purge organic growth without splintering the grain. We’ll leave your backyard retreat sanitized, slip-resistant, and perfectly prepped for a fresh coat of sealant or stain before the next Portage barbecue season kicks off.

In the business world, your storefront is your handshake.

We understand that Portage business owners can't afford downtime, so we coordinate our cleaning shifts around your operating hours to ensure zero disruption to your customers.

Why Portage Homeowners & Businesses Choose Us
At Gunderson Soft Wash Services, we don’t believe in a one-size-fits-all approach. We carefully calibrate our equipment to match the specific architecture of Columbia County, whether we’re treating the weathered brickwork of a downtown Portage landmark or the vinyl siding of a newer build near Slifer Street.
By utilizing low-pressure chemical delivery for delicate roofing and siding, and reserved high-force streams for stubborn masonry and concrete, we ensure a flawless finish without the risk of etched stone or blown seals. Whether your property sits near the Wisconsin River locks or along the busy corridors of Collins Street, we bring the technical precision required to protect your structural integrity while maximizing curb appeal.
We prioritize the local environment as much as we do the results. Our cleaning agents are fully biodegradable and eco-conscious, ensuring the vegetation surrounding your Portage home—from the manicured gardens near Pine Island to the mature oaks in Gunderson Park—remains healthy and vibrant.
You don’t have to trade safety for performance; our solutions are tough on river-valley mold but gentle on your family and pets. Whether we are working on a property near the Portage High School campus or a rural estate out toward Fort Winnebago, you can rest easy knowing we use responsible methods that keep Columbia County beautiful and your loved ones protected.
Traditional pressure washing is like using a weed whacker on a stubborn lawn; it trims the surface but leaves the roots behind to grow back even thicker. Our soft wash system acts like a targeted treatment that pulls the "weeds" of the microscopic world out by the root.
In the humid microclimate around Cascade Mountain or the shaded lots near Lake Mason, organic growth can be relentless. By fully neutralizing the spores instead of just blasting the top layer away, we ensure your Columbia County property stays immaculate for significantly longer. Whether you’re protecting a cottage near Big Spring or a modern home off Townline Road, our deep-cleaning chemistry provides a lasting barrier that keeps your exterior looking freshly detailed while others are already turning green again.
You deserve the peace of mind that comes with hiring true professionals. We aren't just "some guys with a truck"—we are a fully insured operation committed to the highest standards of safety and accountability. Whether we are positioned on a steep roofline in the Hamilton Park area or working near the heavy equipment of an industrial site on Boating Village Road, every square inch of our workspace is covered by comprehensive liability insurance.
Property owners from the quiet stretches of Vilas Road to the bustling commercial blocks near Aspirus Hospital can book our services with absolute certainty. We treat your investment with the same care as our own, providing a layer of protection that ensures your home or business in Columbia County is in the most capable, secure hands possible.
The Fox-Wisconsin Waterway Effect
Where the North Begins — And Where Moisture Accumulates
Portage earned its name from the ancient practice of carrying canoes across the narrow strip of marshy lowland separating the Wisconsin and Fox Rivers — a geography that French explorers Marquette and Joliet crossed in 1673 on their journey to the Mississippi. That same lowland character persists today. The city's floodplain setting, wetlands, and proximity to Swan Lake and Silver Lake create a baseline humidity that encourages algae and mold on exterior surfaces, particularly on properties near the waterways or in areas with heavy tree canopy.
Portage has a significant inventory of older homes — the downtown historic district spans buildings from 1873 to 1920 — and many residential properties throughout the city predate modern exterior coatings. These surfaces often show years of accumulated organic staining that dramatically improves with professional soft washing. We see homes in the Portage area that haven't had exterior cleaning in a decade or more, and the transformation after a single treatment can be remarkable.
Commercial property owners along DeWitt Street and in Portage's business districts benefit from exterior maintenance to attract customers and maintain property values. We work with businesses throughout Columbia County on both one-time cleanings and recurring maintenance schedules, working around your business hours to avoid disrupting customers.
