Our Safe House Washing System Is Ideal

Remove Algae & Dirt Safely

Over time, siding collects algae, mold, and environmental buildup that dulls color and reduces curb appeal. Professional house washing safely removes these contaminants using cleaning methods designed to protect vinyl, wood, stucco, stone and painted surfaces.

Safe for Your Home. Powerful on Buildup.

Soft washing techniques remove algae, mildew, and environmental buildup without the risk of damage associated with high-pressure washing. Your siding, trim, and landscaping are treated with care while contaminants are safely lifted from the surface.

Instead of dull, streaked, or faded siding, you will notice brighter color, cleaner lines, and a more uniform appearance across the entire exterior. The transformation is immediate and noticeable from the street.

A Noticeable Upgrade in Curb Appeal

House washing does more than remove dirt. It restores the original tone of your siding, eliminates dark streaks, and refreshes the overall appearance of your property. Many homeowners are surprised at how much newer their home looks once buildup is removed.
Beyond appearance, professional house washing also helps protect exterior materials from long-term deterioration caused by organic growth and moisture, supporting both curb appeal and property value.

Why Is Soft Washing My Home Important?

Your home is your sanctuary and it needs the proper maintenance to keep its structure.

The care for your home should be at its very best when providing protection for you and your family from outside elements. Hiring a professional to soft wash your home is all a part of caring for it when the time comes. Our DeMark’s cleaning professionals will provide you with superior service by making your home a priority. We will take away the eyesore of dirt built on it with a professional soft wash. 

Will my home be permanently damaged if it is not properly maintained?

The answer is yes. Permanent damage can be caused by dirt and grime if you ignore cleaning your home when the time comes. The winter season will also cause an excessive amount of damage with moisture causing mold and mildew. In the summer months, the beaten-down areas become worse with discoloration, the smell of mildew, and grime continuing to grow.
