Who They're For and What They Solve
Soft washing is an exterior cleaning method that uses low pressure, typically around 100 PSI or less, combined with biodegradable surfactants and algaecides. Instead of blasting contaminants off with force, the solution dwells on the surface, breaks down organic growth at the cellular level, and rinses away clean.
You need it whenever a surface is too fragile for high pressure. That includes stucco, painted or vinyl siding, asphalt and tile roofing, window screens, soffits, eaves, and older wood. Homeowners usually call after spotting dark roof streaks, a green haze on north-facing walls, or receiving an HOA notice.
Soft washing solves organic staining that pressure alone cannot fix. Algae, mildew, mold, moss, and lichen have root structures that survive a rinse and regrow within months. Left alone, lichen etches roofing granules and moisture-holding growth accelerates rot on wood, paint, and stucco over time.
Is It Time?
Most people notice one of these before they call us.
Our Services
Soft washing applies differently depending on what we are cleaning. Here is how we handle each surface type.
We apply solution at near-zero pressure across shingles or tile, let it dwell to kill algae and lichen at the root, then rinse gently. This is the manufacturer-approved approach for asphalt roofing and protects granule adhesion and warranty coverage.
Textured stucco traps mildew deep in its pores, and painted siding cannot take direct force. We adjust surfactant strength to the substrate, work in overlapping sections, and rinse thoroughly so no residue streaks or shadows are left behind.
Window screens, vented soffits, and overhead trim dent and tear under pressure. We use the lowest setting with a mild solution to lift dust, cobwebs, and mildew from mesh and painted trim without warping frames or forcing water into vents.
Fences, pergolas, and composite decking gray out from mildew and UV exposure. Pressure raises wood grain and scars composite. Low-pressure treatment restores color evenly and leaves the surface intact and ready for sealing if you choose.

Why Homeowners Choose Mr. Local Services
If our method damages a properly disclosed surface, we repair it. That commitment is backed by $2 million in general liability coverage and written into every quote we hand you.
Every technician is trained to identify substrate type and match solution ratio and pressure to it. Soft washing fails when someone guesses. Ours don't guess, they assess first.
The number on your written quote is the number you pay. No change orders, no surprise square footage adjustments, no add-ons discovered halfway through the job.
Plants get pre-wet before we start, covered where needed, and rinsed thoroughly after. This is standard on every soft wash, not an upgrade you have to ask for.
How It Works
Call 951-458-6466 and tell us what you’re seeing and what the surface is. We’ll schedule an on-site assessment, usually within 48 hours.
We inspect substrate condition, measure the area, check access and drainage, then hand you an itemized written quote before leaving. No obligation attached.
We cover and pre-wet landscaping, apply solution at the correct ratio, allow proper dwell time, then rinse at low pressure across the full surface.
We walk the property with you and confirm results section by section. Anything missed gets corrected on the spot, and your guarantee is documented.
Pricing
We’d rather give you a real number than tell you to call for pricing. Cost depends on a few honest variables.
What affects your price: total square footage, surface type (roofing costs more than siding due to access and dwell requirements), height and access difficulty, and severity of existing growth.
Typical ranges: a standard single-story house wash runs $275 to $475. Roof soft washing typically falls between $425 and $850 depending on pitch and size. Fence or deck treatment generally runs $150 to $400.
Results typically last 12 to 24 months depending on shade and moisture exposure. Your written quote locks the price before any work begins.
Soft washing uses around 100 PSI plus cleaning solution to kill organic growth. If your surface is durable concrete or masonry, our pressure washing service uses 1,500 to 4,000 PSI instead.
No. We pre-wet and cover landscaping before application and rinse thoroughly afterward. Our solutions are biodegradable and diluted specifically for this protocol.
Typically 12 to 24 months. Heavily shaded or moisture-prone areas regrow sooner than sun-exposed surfaces, which is normal for organic growth.
Yes. Low-pressure chemical cleaning is the method most asphalt shingle manufacturers approve. High pressure is what voids coverage by dislodging granules.
It will not remove oil stains, rust, paint overspray, or contaminants embedded deep in concrete. Those need different treatments, and we'll tell you upfront.
Most residential soft washing takes two to four hours. Larger properties or roof work can run a full day depending on access.
Call 951-458-6466 and we'll schedule your free on-site assessment, usually within 48 hours, with a written quote before we leave.
Every wet season makes organic growth harder and more expensive to remove, and your assessment is free either way. Get a written quote before you commit to anything.
