Gentle on Wood. Tough on Grime.
Decks, log homes, fences, and patios take a beating from Wisconsin weather. Our soft wash technique lifts years of gray weathering, mold, and algae without splintering, gouging, or damaging the wood grain — leaving a surface that's ready to stain, seal, or simply enjoy.
Deck Cleaning & Restoration
Pressure washing splinters wood and causes more harm than good. Our soft wash method cleans gently but thoroughly — killing mold and algae at the root without damaging your deck boards, railings, or stairs.
Log Home Soft Washing
Log homes need specialized care — not a pressure washer. Our soft wash process kills years of grime, algae, and buildup at the source without stripping the finish or damaging the wood. Your logs deserve better.
Why Soft Wash for Wood?
- No splintering or grain damage from high pressure
- Kills mold, mildew, and algae at the root — not just the surface
- Prepares wood perfectly for staining or sealing
- Safe for people & pets
Gray, weathered boards brought back to life
Full exterior transformation — railings, deck, and siding
What Our Customers Say
100% recommend rate across 11 Facebook reviews. Real feedback from real homeowners in Wisconsin.
"So happy we decided to have Chris and his team clean the roofs, siding, concrete patio, etc... the house looks great!!! I can't believe they got the stains from the chimney off of the siding — I had tried several different cleaners over the 20+ years we have been here and nothing worked. They got it looking like brand new in one day. Best decision ever!!"
"They did a great job! My house looks so much better. And the guys were very nice."
"Very responsive and professional. Did a wonderful job! Everything looked fantastic when completed."
"Used Water Otter for our spring power washing and the old house looks brand new! Highly recommend Chris and his team!"
"We had them out a few years ago. They did our roof and the rest of the house, and it has been clean ever since then. I like the soft wash system as it will not harm the roof. Worth every penny. I highly recommend Water Otter!"
"I had my house, 3-car detached garage, storage shed, composite deck, and sidewalks power washed by Water Otter. They called the day before to reconfirm arrival time. Arrived on time and performed an outstanding job!"

Common Questions
Soft washing uses low-pressure water and professional-grade cleaning products to kill algae, mold, mildew, and stains at the source. Unlike pressure washing, which can damage siding, shingles, and wood, soft washing gets the job done without any risk to your home's surfaces.
Absolutely. Soft washing is the method recommended by shingle manufacturers like GAF and CertainTeed. The low-pressure technique is gentle enough for all exterior surfaces including asphalt shingles, vinyl siding, wood, stucco, and brick.
Every home is different, which is why we provide free, no-obligation estimates. The cost depends on the size of the area being cleaned and the level of buildup. Contact us for a personalized quote — most homeowners are pleasantly surprised by how affordable it is compared to replacement.
We proudly serve homeowners and businesses across select counties in South Central Wisconsin. Give us a call at (608) 697-5279 to confirm we cover your area.
Yes — our products are safe for people and pets. We do take precautions to protect your landscaping during the process, as the cleaning solutions can be tough on plants if not managed properly.
Depending on your home's environment and exposure, soft washing results typically last 2-3 years for roofs and 1-2 years for siding and concrete. Regular maintenance cleanings can extend these results even further.
