Beaver Dam is a working city. It has a manufacturing base, a busy commercial district, older neighborhoods with homes that were built to last, and Beaver Dam Lake sitting right alongside all of it. That combination of mature tree canopy, a large body of water, and decades-old housing stock is exactly what creates the conditions we deal with most. Roofs develop black streaks faster than people expect. Siding on the north and west sides of a house greens up by early summer. Driveways in neighborhoods that have been there for 50 years carry a level of embedded grime that a garden hose was never going to touch.
We serve Beaver Dam and the surrounding Dodge County area including Horicon, Waupun, Juneau, and Columbus. For homeowners, that usually means a roof wash or a full exterior cleaning before a sale, after a wet spring, or just because it's been a few years and the property is due. For commercial property owners along Front Street or near the Dodge County Fairgrounds, it means a clean building that tells customers something before they even walk in the door.
Every quote is free and we turn them around within 24 hours. Scheduling works around you, not around us.

We offer a complete range of exterior cleaning services for Beaver Dam residential and commercial properties.

Our low-pressure soft wash system safely cleans roofs, siding, fences, and other delicate surfaces. Biodegradable solutions kill algae, mold, and mildew at the root — delivering results that last 2–3 years.
High-pressure cleaning for concrete driveways, sidewalks, patios, and hard surfaces. We remove embedded oil stains, dirt, and organic buildup that years of weather have packed into the surface.
Those black streaks on your shingles aren’t just dirt; they’re actually Gloeocapsa magma, a bacterium that feeds on the limestone filler in your roof.
Our professional Soft Wash system uses eco-friendly, low-pressure treatments to eliminate staining, moss, and lichen at the root. This gentle approach improves curb appeal, protects roof and helps reflect heat.
Oil stains, tire marks, algae, and years of embedded grime don't stand a chance against our commercial pressure washing equipment. We restore concrete and asphalt driveways to like-new condition.
Wisconsin's freeze-thaw cycles and humid summers accelerate mold and algae on decks. We match pressure and cleaning solutions to your deck material — wood or composite — leaving it clean and ready for staining or sealing.
From spotless storefronts to grime-free parking lots, we keep your Beaver Dam property looking its best. We work around your clock—not ours—to provide high-quality commercial washing with minimal disruption to your customers.

We're not a one-size-fits-all pressure washing service. Here's what makes Gunderson Soft Wash the right choice for Dodge County properties.
We assess every surface before we start. Roofs and siding get soft washing; concrete and hard surfaces get pressure washing. The right method protects your property and gets better results.
Our cleaning agents are environmentally responsible — safe for your landscaping, pets, and family. We don't compromise on cleaning power to get there.
Soft washing kills organic growth at the biological level rather than just rinsing it away. Your surfaces stay cleaner far longer than with pressure washing alone.
We carry full liability insurance on every job. You can book with confidence knowing your property is protected throughout the entire cleaning process.
Beaver Dam sits alongside Beaver Dam Lake — the 16th largest lake in Wisconsin, covering 6,718 acres with 41 miles of shoreline — in northwestern Dodge County. The city was settled in 1841 and named for an old beaver dam in a stream flowing into the Beaver Dam River, a history reflected in its glacially-shaped landscape of rolling drumlin hills and the lake that dominates the local geography. The Menominee people knew this place as Okwaanim — their word for beaver dam.
Beaver Dam Lake creates a persistent moisture environment for the surrounding neighborhoods, particularly on properties with northern exposures or under mature tree canopy. Algae, mold, and black streaks are consistent findings on roofs and siding throughout the Beaver Dam area — and the lake's influence is felt several blocks back from the shoreline. Soft washing addresses these organic growth issues at the biological level, eliminating what you can see and what you can't, rather than simply washing the surface.
Beaver Dam's commercial corridor along Front Street, Spring Street, and near the Dodge County Fairgrounds supports a regional economy anchored in manufacturing, healthcare, and agriculture. For commercial property owners in Beaver Dam, a clean exterior is a practical investment in first impressions. We serve businesses and property managers throughout Dodge County with commercial building washing, storefront cleaning, and parking area pressure washing.
