Soft Wash House Washing
The Gwinnett County soft wash house washing done the right way.
Georgia humidity is brutal on a home. Within 12 to 24 months of a fresh clean, most houses in Gwinnett County start growing a thin green film of algae along the north-facing walls, black mildew stains under the gutters, and dark streaks at the roofline. Left alone, that organic growth eats into vinyl siding, discolors Hardie board, and works its way into stucco and mortar joints — quietly dropping thousands of dollars off your home's curb appeal.
Mold Buster Pressure Washing exists to reverse that damage — permanently, and without the risks that come with high-pressure blasting. Our soft washing house process uses low pressure (under 500 PSI, roughly the strength of a garden hose) combined with a biodegradable, plant-safe cleaning solution that kills mold, mildew, algae, and bacteria at the root. The result: siding that looks like it did the day you bought the home, with a clean that lasts three to four times longer than a standard pressure wash.
We've soft washed thousands of homes across Lawrenceville, Duluth, Suwanee, Buford, Dacula, Snellville, Grayson, and Sugar Hill — from starter homes in older subdivisions to executive estates in Sugarloaf Country Club, Hamilton Mill, and The River Club. If your home is in Gwinnett, we know exactly how to clean it.
Why Soft Wash
Why we never point a high-pressure wand at your siding.
Low pressure, real chemistry
Our surfactants do the work — not brute force. Pressure this low can't crack stucco, force water behind siding, or etch brick mortar.
Manufacturer-approved
Soft washing is the only cleaning method approved by James Hardie, vinyl siding manufacturers, and ARMA for shingled roofs.
Landscape safe
We pre-saturate every plant and shrub, use plant-safe solution, and post-rinse the beds. Zero landscape damage — guaranteed in writing.
Cleans 3–4x longer
High-pressure rinses knock the color off but leave the roots. Ours kills the organism. That's why our house washes last so much longer.

03
Soft wash & dwell
Our low-pressure applicator coats the entire home top-to-bottom with our mold-killing solution. Dwell time is what actually cleans the house.

Local Expertise
House washing across every corner of Gwinnett County.
Every neighborhood in Gwinnett has its own quirks. House washing in Lawrenceville around older brick homes off Sugarloaf Parkway means paying close attention to mortar joints and cedar trim. In the newer builds around Rock Springs and Alcovy, the challenge is heavy pollen and pine sap on Hardie plank. In house washing Duluth — especially the golf-course communities off Sugarloaf Country Club Parkway — we deal with irrigation-fed mildew and lakeside algae. Along Highway 20 in Buford and Sugar Hill, red clay staining on light-colored stucco is the real enemy.
Because our crews live and work in Gwinnett, we know which stains actually come out, which ones need a two-pass treatment, and which ones aren't stains at all (they're oxidation, and no amount of pressure will lift them — but our brightener will). It's the difference between a company that shows up to spray water and a company that shows up to solve the problem.
Pair your house washing with a roof soft wash or driveway cleaning and most homeowners save 10–15% on the full exterior refresh.
Surfaces
Every siding type — cleaned the right way.
Vinyl siding
The most common siding in Gwinnett. We soft wash to lift green algae and black mildew without the streaking that high pressure causes on lap seams.
Hardie board & fiber cement
James Hardie explicitly requires low-pressure cleaning. Our system meets their warranty specs so you don't void a thing.
Brick & stucco
We adjust dwell time and dilution ratios for masonry. No etched mortar, no chipped stucco — just clean brick.
Cedar & wood siding
Delicate wood siding gets our gentlest touch, plus an optional wood brightener to even out sun-faded panels.
Aluminum & steel siding
Older homes with metal siding need pH-balanced chemistry to avoid oxidation. We use it every time.
Trim, soffits & gutter faces
The dirty streaks running down your gutters aren't dirt — they're a bacteria called Gloeocapsa. We remove them completely.

(770) 846-7699What is soft washing and why is it better than pressure washing for my house?+
Soft washing is a low-pressure cleaning method (under 500 PSI, about the strength of a garden hose) that uses a biodegradable surfactant solution to kill mold, mildew, algae, and bacteria at the root. Traditional high-pressure washing on siding can force water behind panels, crack stucco, etch brick mortar, and strip paint. Every reputable Gwinnett County house washing company — including Mold Buster — soft washes homes. It's the only method approved by vinyl and Hardie siding manufacturers.
How much does house washing in Gwinnett County cost?+
Most single-story homes in Lawrenceville, Duluth, and surrounding Gwinnett cities fall between $299 and $449. Two-story homes typically run $399 to $649 depending on square footage, height, and level of mildew. Larger executive homes in Sugarloaf, Hamilton Mill, and River Club start around $549. We provide free, no-obligation quotes with firm pricing — no surprise upcharges on the day of service.
How long does a house washing take?+
A typical Gwinnett County home takes 1.5 to 3 hours from setup to final rinse. We do not require you to be home — most of our customers are at work when we arrive. You'll get a text when we're on the way and another when the job is complete.
Will house washing kill my plants or hurt my landscaping?+
No. Before we start, we saturate every plant, shrub, and flower bed within reach of overspray with fresh water. We use plant-safe surfactants and rinse landscaping again after the wash. In seven years of house washing across Duluth, Lawrenceville, and Suwanee, we've never damaged a customer's landscaping — and we guarantee it in writing.
How often should I have my house washed?+
In Gwinnett County's humid Georgia climate, most homes benefit from a soft wash every 12 to 18 months. North-facing walls, homes under heavy tree cover, and homes near creeks or ponds may need it annually. If you can see green or black staining on your siding, it's time.
Do you service my neighborhood?+
Yes — we service all of Gwinnett County including Lawrenceville, Duluth, Suwanee, Buford, Dacula, Snellville, Grayson, and Sugar Hill. We're based locally and our crews are on the road in Gwinnett every single day.
Is your work insured and guaranteed?+
Yes. Mold Buster carries $2,000,000 in general liability insurance and provides a Certificate of Insurance on request for HOAs and property managers. Every house washing comes with our satisfaction guarantee: if you see a spot we missed, we come back at no cost.
