We clean everything. Get your house soft washed today by a professional. Washing your home will kill mold, mildew and fungus. We can get some of the toughest stains out without damaging the surface. Stains caused by algae, dirt, and debris are quickly removed.

We clean siding, vinyl, brick, stucco, aluminum, concrete, painted wood, trim, PVC, plastic, masonry, all types of roofing and gutters. There are some special techniques we’ve discovered that work well in many circumstances, but each situation needs to be assessed individually.

Soft washing is a completely different cleaning method than pressure washing with cold or hot water, and low pressure steam cleaning. Soft washing uses low pressure to clean the exterior of your home using biodegradable, eco-friendly cleaning solutions. Typically a mixture of Sodium Hypochlorite, water, and a surfactant are used to safely remove mildew, bacteria, algae and other organic stains from roofs and exteriors. A soft wash uses Sodium Hypochlorite, biodegradable soap as a surfactant, and water. Sodium Hypochlorite is a liquid Chlorine and has around 10-12% available Chlorine. This is further diluted down to between 1 and 5%. Sodium Hypochlorite is what is used in your pool. Sodium Hypochlorite is not bleach. We will not harm your plants when we wash your home, and you will be very pleased with the results!

Gloeocapsa magma is the algae that grows on composition shingles, causing unsightly streaks and stains. Most people judge the age and condition of a home’s roof based on the way it looks. If a home has a lot of dark streaks on the roof, prospective buyers of that home assume the roof is on its last legs and, as a result, the roof condition becomes a bargaining point for the home’s value. Beyond that, these dark stains also have a huge bearing on the curb appeal of a home. If you’re like most homeowners, that means something to you. You want your home to look as good as possible.

In order to keep down their cost and create more profit, shingle manufacturers want to use more “fillers” in the composition of asphalt shingles. Petroleum is expensive these days. One of these fillers is limestone. It is the calcium carbonate in limestone that gloeocapsa magma really likes to feed off of, along with moisture that naturally collects on a roof’s surface. Once the algae growth becomes noticeable (dark streaks on the roof), gravity and rain water flowing down the roof carry the spores down the roof, causing the commonly seen pattern of streaks extending downward on the roof.

This, combined with a darker color that absorbs more heat, deteriorates the shingles faster.

A house soft wash and rinse will kill and remove unsightly organic growth on your home
