Mauston is home base for us. This is where we started, where we live, and where we know every neighborhood well enough to tell you which streets see the most roof algae by midsummer and which driveways take the worst beating from a hard winter. When you hire Gunderson Soft Wash, you're not getting a crew that drove two hours and is guessing at what your property needs. You're getting the guys who know Juneau County.
The Lemonweir River valley holds moisture in a way that flat, open areas just don't. Cool air settles into the valley on spring and fall nights, dew points stay elevated longer than people expect, and that combination is why so many Mauston roofs develop black algae streaks faster than homeowners expect. It's also why siding on north-facing walls greens up by June and why wood decks around here take a beating that decks in drier climates simply don't see. We're not explaining this to sell you something. We're explaining it because understanding the local climate is what tells us which cleaning method your property actually needs and how long the results will hold.
We use low-pressure soft washing for roofs, siding, fences, and any surface that can't take high-pressure water without damage. The cleaning solution does the work, killing algae, mold, and mildew at the root rather than just rinsing the surface clean. Results typically last two to three years. For concrete driveways, sidewalks, and hard surfaces, we switch to commercial pressure washing because those materials can handle it and need the extra force to pull out embedded grime and oil. Every job gets assessed before we start so the right method goes to the right surface.
We serve Mauston and the surrounding Juneau County area including New Lisbon, Necedah, Elroy, Hustler, and Wonewoc. Residential or commercial, large property or small, every job gets the same equipment and the same level of care. We're fully insured, we respond within 24 hours, and every quote is free with no obligation attached.

From rooftops to driveways, we provide Mauston properties with expert cleaning that protects your investment and boosts curb appeal. Whether it’s a historic home or a modern storefront, we clean every surface the right way.

Our signature low-pressure soft wash safely removes algae, mold, mildew, and bacteria from siding, stucco, fences, and other delicate surfaces — without risk of damage from high-pressure water.
For hard, durable surfaces that can handle high-pressure water (concrete, brick, pavers, and commercial surfaces) pressure washing delivers a deep, powerful clean that removes years of built-up grime and staining.
Those black streaks on your roof are Gloeocapsa magma (an algae) that eats away at shingles over time. Our soft wash roof cleaning eliminates algae, moss, and lichen at the root, restoring your roof's appearance and extending its life. Safe for all shingle types.
Oil stains, tire marks, rust, and algae growth make driveways look neglected. Our pressure washing service lifts deep-set stains from concrete and asphalt driveways, restoring a clean, uniform appearance that makes your whole property look sharper.
Wisconsin weather is tough on wood and composite decks. Mold, mildew, green algae, and gray weathering build up fast. Our deck cleaning service uses the right pressure and the right solution for your deck's material, leaving it clean, safe, and ready for staining or sealing.
First impressions matter for your business. We provide commercial building washing, storefront cleaning, and parking lot pressure washing for Mauston businesses of all sizes (scheduled around your hours to minimize disruption).

We match the cleaning method to each surface: soft wash for roofs and siding, pressure wash for concrete and brick — to get the best result without causing damage.
Our cleaning agents are environmentally responsible and safe for your landscaping, pets, and family; without sacrificing cleaning power.
Soft washing kills organic growth at the root rather than just rinsing it away. Your surfaces stay cleaner for months longer than with pressure washing alone.
Every job is covered. We carry full liability insurance so you can book with confidence and know your property is protected.
Mauston's location in the Lemonweir River valley means properties here experience higher ambient moisture levels than homes in more exposed areas. That humidity, particularly in spring and fall when temperatures swing and dew points stay elevated, creates ideal conditions for algae, mold, and lichen to establish and spread on exterior surfaces. Roofs and north-facing siding are the most common problem areas we see on service calls in Mauston.
Mauston also has a significant number of older homes, properties that may have decades-old wood siding, aging asphalt shingles, or concrete driveways that have never been professionally cleaned. These surfaces often respond dramatically to soft washing, with results that genuinely look like new construction after a single treatment.
For commercial property owners along Highway 82 and the downtown corridor, exterior appearance matters year-round. We work with Mauston businesses on both one-time cleanups and recurring maintenance schedules to keep storefronts and building exteriors looking professional every season.
