Siding Cleaning Overview

Your home’s siding is not only an essential part of its exterior appearance but also a protective layer that shields it from harsh elements. Over time, your siding can accumulate dirt, grime, and other types of organic matter, which can not only detract from its appearance but also lead to damage. Fortunately, there is a way to clean your siding effectively and safely without causing any damage. This method is called soft washing.

What is Siding Soft Washing?

Siding soft washing is the safe alternative to pressure washing.  It is a method of cleaning siding that involves using low-pressure water streams, and specialized cleaning solutions to remove dirt, grime, and other organic matter. This method is much gentler than traditional power washing, which will damage your siding and lead to costly repairs.

What types of Siding do you Clean?

  • Vinyl Siding 
  • Metal Siding
  • Wood Siding
  • Composite Siding

Why should I clean my siding?

Many people wonder, why do I need my roof cleaned? This is a very valid question and one that we used to ask as well. To start you need to understand a few basic facts. First, the growth that you may (or may not see) on your roof is a living organism that is most commonly Gleocapsa Magma, or may include other types of algae, lichens, bacteria, etc. The exact type of living organism is generally unimportant. What is important is that it is living and therefore needs to eatto survive. So what does it eat? It eats limestone and limestone is the aggregate that is used in asphalt shingles.  The natural result of this is that your roof deteriorates much more quickly because it is literally being eaten and eroded.

Steps Involved in Roof Soft Washing

  1. Prepare – Our top priority it to protect your property, so the first thing we do is identify and protect any delicate surfaces or items around your property, including plants.
  2. Hydrate – The next step is to hydrate all plants in the area that we will be cleaning, including grass.  By diluting with water, we help keep the pH levels of the plants at a neutral state.
  3. Service – Once the property is prepared and all the plants are hydrated, we can begin the cleaning process. We work from top to bottom, left to right while carefully sanitizing every exterior surface.
  4. Rejuvenate – After the cleaning service is completed, we once again rehydrate the plants to ensure our cleaning solution is thoroughly diluted, and then we spray them with our proprietary plant-care solution.
  5. Clean Up – When we are finished, we carefully roll up our hoses, collect equipment, and leave your property in better condition than how we found it.

Benefits of Roof Softwashing

There are several benefits to using roof soft washing over other roof cleaning methods, including:

  • Protection – Soft washing is a gentler method that helps protect your siding from damage, extending its lifespan.
  • Efficiency –  Soft washing can effectively clean your siding without the need for high-pressure water or harsh chemicals, making it more efficient and eco-friendly.
  • Aesthetics – Soft washing can help improve the curb appeal of your property by removing unsightly stains and streaks.
  • Safety – Soft washing is a safer option than power washing since it uses lower pressure and doesn’t risk damaging your roof or injuring people or pets in the area.

When should you consider Siding Cleaning?

It’s important to consider siding soft washing when you notice that your siding is accumulating dirt, grime, or organic matter. Some signs that you may need a siding softwashing service include:

  • Discoloration or stains on your siding
  • Algae or moss growth

In general, it’s recommended to have your siding cleaned every 2-5 years, depending on your location and the type of siding material.

Frequently Asked Questions


Soft washing is not the cheapest cleaning method, but it does bring the most value.  We are also not the cheapest cleaning service, but we will bring the most value.  There are companies out there that will show up for very little and pressure wash your roof or soft wash it using improper techniques and under-trained staff.  This may seem appealing due to the low upfront cost, but it's highly likely to result in greater costs down the road when things are damaged or need to be recleaned far too soon.


Bleach is safe for softwash cleaning when used properly because it is a highly effective cleaning solution that can break down and remove organic stains, kill bacteria and viruses, and sanitize outdoor surfaces without causing damage when diluted correctly and used with appropriate safety measures.  Learn more in this blog written on the subject.


Soft washing is a great way to clean the exterior of your home or business without causing damage. However, it's important to take extra precautions when cleaning around plants and landscaping. The Three D's - Divert, Dilute, and Decontaminate - are the key techniques used to protect your plants during a soft washing job.  Learn more in this blog we wrote on the subject.


During the cleaning process, we ask that any pets remain in the home or outside the cleaning area. After the job is completed, the yard is completely safe for your pets to access. We rinse and neutralize areas after the cleaning. If anything is remaining on the grass, it would be similar to what your pet may experience in pool water, since sanitizing agents in pools are the same as what we use.


Bleach is the most widely used and effective cleaning solution in the world. It’s used in far more processes than most people realize in the products and services we rely on every day. Surprisingly, it is also very environmentally friendly and is formed simply from salt and water, and returns to its natural state 20 days after use. Bleach even occurs naturally in nature in a place some of you may have visited, Lake Lucero in Great White Sands National Park.

Roof Treatment Softwash


Here in Wisconsin, bacteria and mildew builds up on roofs, leaving unsightly black spots and streaks. We see a lot of rust from vent pipes that leak down homes too. When we softwash your roof, we not only kill the organic growth that’s eroding your shingles and tiles, we revive inorganic surfaces like tile, metal and powder coatings.

Exterior and Siding, Softwash


Keeping your home’s exterior sanitized is not only visually pleasing, it retains the value of your home. UV damage will wear down on your home, and cause siding to become brittle and crack when pressure is applied to it. SoftWashing rejuvenates exterior surfaces by providing a buffing agent to keep damage at bay until the next treatment.

Driveway and Walkways, Softwash


Our home’s concrete surfaces see the most wear, leaving them to be highly susceptible to additional erosion from the blowing and blasting of a pressure washer, which can also reveal the aggregate under the surface. SoftWashing leaves a residual inhibitor to your surface that keeps them treated for 6x longer, guaranteed.

Solar Panels, Softwash


Dirt and grime can reduce the efficiencies of solar power systems by almost 20%. Routine maintenance softwashing keeps your panels producing all year long.

Gutters, Softwash


Striping occurs when pollution, oxidation and dirt run down the gutters over a long period causing the unsightly stripes. SoftWashing delivers the right ratio of chemicals to the area leaving it spotless every time, while protecting soffits and fascia.

Roof Treatment Softwash


SoftWashing works perfectly with windows, where pressure is not necessary. We use low pressures to deliver our solution, which has a waxing agent to make them really pop when we’re done. Our pure water final application leaves them spot-free.
