What Is Soft Washing and Why DFW Homes Need It
Soft washing is low-pressure cleaning that uses chemical solutions to do the cleaning work rather than water pressure. Applied at 100-500 PSI (compared to standard pressure washing at 2,000-3,000 PSI), soft washing safely cleans surfaces that would be damaged by high pressure — including brick, stucco, Hardie Board, wood, EIFS, and painted surfaces.
DFW homes benefit particularly from soft washing because the region's primary soiling challenge is biological — mold, algae, pollen, and mildew that require chemical treatment to kill, not just mechanical water pressure to move. Soft washing chemistry kills biological growth at the root while the low-pressure application protects surface integrity.
Most DFW exterior surfaces that aren't bare concrete should be soft washed rather than pressure washed. This includes brick (which loses mortar at high pressure), Hardie Board and vinyl siding (manufacturer warranties specify low-pressure washing), painted surfaces (high pressure lifts paint), and roofs (high pressure removes shingle granules).
2025 DFW Soft Washing Pricing
House exterior soft washing (single-story, approximately 1,800 sq ft of wall): $145-$325. Two-story homes: $200-$425. The variation reflects the extent of biological growth and number of special-care areas (overhangs, detailed trim).
Roof soft washing (2,000-3,000 sq ft roofline): $200-$550 depending on pitch and algae severity.
Fence soft washing: $1.00-$2.50 per linear foot. Cedar and wood fences with heavy biological growth run toward the higher end.
Deck soft washing: $0.10-$0.20 per sq ft. A 400 sq ft deck runs $40-$80 for soft washing alone, though most deck cleaning also benefits from a higher-pressure final rinse.
What to Ask Before Hiring
Ask any DFW soft washing company: What PSI do you use? What chemistry do you apply, and is it biodegradable? Do you rinse plants and landscaping before and after application? Do you use a post-treatment biological inhibitor? These questions separate professional operations from those who just apply diluted bleach and call it soft washing. Blues Home Services uses professional biodegradable soft washing chemistry with post-treatment application throughout DFW. Call (214) 307-2127.
