Soft Washing Service
Fabricio Painting provides soft washing in South Dennis, MA, for roofs, siding, decks, and outdoor structures. Most homes run roughly $400 to $700 and finish in a few hours on site. We apply a low-pressure surfactant-and-sodium-hypochlorite mix, under 500 PSI, to kill algae, mold, mildew, and black streaking at the root rather than blasting it off the surface. Cape Cod's damp, salt-laden air and shaded north-facing roofs and bayside siding feed organic growth faster than inland homes, making soft washing the right intervention before repainting or before the next selling season. Fabricio Painting holds a 5-star rating across 135 Google reviews and has been cleaning and painting Cape homes since 2007.
Soft Washing
Soft washing on Cape Cod is not a pressure problem solved with more PSI. Salt air, heavy shade from pitch pines and oaks, and the moisture that hangs off Nantucket Sound feed algae, mold, and black streaking into roof shingles, vinyl siding, and deck boards faster than most homeowners expect. The pressure that cleans a concrete driveway is the pressure that lifts shingles, drives water behind siding seams, and furs up softwood grain. Delicate surfaces need chemistry, not force.
Fabricio Painting handles soft washing in South Dennis for roofs, siding, decks, fences, and freestanding structures throughout Cape Cod, setting the sodium hypochlorite mix ratio and dwell time to the material rather than running one setting across every surface. Most projects run roughly $400 to $700 and finish the same day, leaving organic growth killed at the root and every surface visibly clear of algae, mildew, and black streaking, ready for immediate use or for painting and staining once dry time requirements are met.
Sub Services
Soft washing covers every exterior surface where organic growth takes hold but pressure would do damage. Each surface below is part of our full exterior cleaning offer. For a complete picture of what we cover, see our Cape Cod pressure washing services hub.
Shingle, metal, and slate roofs grow black streaking from Gloeocapsa algae, plus moss in shaded valleys. We apply chemistry through a downstream injector at under 500 PSI, never a wand bearing down on the shingles. The solution dwells to break down the organism at the root before a cold-water rinse clears it. Best for Cape homes where the north slope has gone dark.
Vinyl, wood, stucco, and fiber cement all clean with soft washing, each at its own sodium hypochlorite dilution. Painted wood takes a lighter mix so the finish is not stripped; algae-heavy vinyl takes a stronger one. The right call for bayside homes off 6A where shaded walls green up between seasons and mildew accelerates paint degradation.
Decks and fences hold mildew in the grain and along shaded rails. A soft wash lifts organic growth without the fuzzing and splintering that high pressure leaves in softwood. Boards, railings, and spindles get the full chemical application and low-pressure rinse treatment. Best before a re-stain or any time the boards feel slick underfoot.
Gutters and fascia boards collect black oxidation streaks and mold from standing moisture. We treat the exterior face of gutters and the full fascia run with a surfactant blend that breaks down streaking during dwell time, then rinses clean without forcing water behind the board or into the soffit. Often bundled with a full house or roof wash.
Sheds, pergolas, and dock structures weather the same organic film as the house but often get skipped. Soft washing reaches them without forcing water into joints or lap seams. Covers the full structure including railings, posts, and roof surfaces. Best when you want the whole property to match, not just the main roofline, in one scheduled visit.
Homeowner Guide
Shingle, metal, and slate roofs develop black streaking from Gloeocapsa algae and collect moss in shaded valleys. A roof gets the gentlest possible contact: a sodium hypochlorite and surfactant mix delivered through a downstream injector at under 500 PSI, never a wand bearing down on the surface. Dwell time does the work, and a cold water rinse clears the residue without lifting shingles or saturating ridge vents.
Vinyl, wood, stucco, and fiber cement siding all clean with soft washing, each at its own dilution ratio. Painted wood takes a lighter mix to preserve the finish, while algae-heavy vinyl takes a stronger one. Bayside homes along Route 6A where shaded walls green up between seasons see the biggest turnaround. The process removes mildew and mold at the root, slowing regrowth and protecting the paint underneath.
Decks and fences hold mildew in the grain and along shaded rails. A soft wash lifts growth without the fiber fuzzing and splintering that high pressure leaves in softwood boards. Every wash covers the full surface, including railings, spindles, stair treads, and the joints where grime collects most. This is the right step before a re-stain, or any time boards feel slick underfoot.
Sheds, pergolas, and dock structures weather the same organic film as the house but are often skipped during routine cleaning. Soft washing reaches them without forcing water into joints or lap seams. What is not included by default in a standard soft wash: window screen removal, gutter interior clearing, paint repair, and oxalic acid rust or tannin treatment. Those are available as add-ons and can be bundled at the time of estimate.

Frequently Asked Questions
Get answers to common questions about soft washing costs, chemicals, surfaces, preparation, and what to expect from a job in South Dennis and across Cape Cod.
A 1,500 to 2,000 square foot house or roof soft wash runs two to four hours on site. Smaller single-story homes or decks finish in one to two hours. Larger two-story homes or jobs combining house, roof, and deck can run a half day to a full day, since chemical dwell time adds to the clock regardless of size.
We soft wash roof shingles, metal and slate roofing, vinyl, wood, stucco, and fiber-cement siding, along with decks, fences, gutters, fascia, sheds, pergolas, and docks. Every job includes chemical application, low-pressure rinse, and plant and fixture protection. Window screen removal, gutter interior clearing, paint repair, and oxalic acid rust or tannin treatment are not included by default.
Visible algae streaks, green or black mold patches, and moss growth are the clearest signals. On roofing, dark streaking is almost always Gloeocapsa algae feeding on the shingle surface. On siding, mildew and mold buildup accelerate paint degradation. If organic growth is visible from the curb, soft washing is the appropriate intervention before repainting or before the next selling season.
Soft washing in South Dennis typically runs $0.25 to $0.35 per square foot, roughly $400 to $700 for a standard house or roof wash. Square footage, number of stories, siding or roofing material, algae severity, site accessibility, and whether oxalic acid treatment is needed all move the final number.

We apply a blend of sodium hypochlorite diluted to a job-specific ratio, a surfactant for coverage and dwell, and plant-safe neutralizer rinse agents delivered through a low-pressure downstream or pump sprayer. Before any chemical touches the exterior, we pre-soak and cover all landscaping, HVAC units, and electrical fixtures, then rinse them again at close.
Sodium hypochlorite breaks down the cell structure of algae and mold colonies during dwell time, killing the organism rather than rinsing the surface. The solution sits five to fifteen minutes before the low-pressure fresh-water rinse clears it. That process removes the growth at the root and slows regrowth, rather than producing a cosmetic result that returns within a season.
Close all windows and doors, move outdoor furniture away from the exterior walls, and let us know about any sensitive plantings close to the foundation. We pre-wet and cover landscaping, HVAC units, and electrical fixtures before application, and rinse them again after. No other preparation is typically needed on your end.
We run soft washing throughout the full service area, including Yarmouth, Barnstable, Hyannis, Osterville, Centerville, Harwich, Brewster, Chatham, Orleans, Mashpee, Sandwich, Falmouth, and Eastham.
