Professional exterior cleaning for Cumming and Forsyth County
Cumming has become one of the fastest-growing communities in the entire United States over the past decade, with Forsyth County ranking among the top counties in the nation for population growth year after year. The combination of top-rated schools, large-lot subdivisions, lower property taxes than neighboring Fulton and Cherokee counties, and convenient access to the GA-400 corridor has driven a sustained building boom that has transformed Cumming from a small county seat into a thriving suburban city. The result is a landscape of newer, larger homes — many with extensive exterior surfaces — in planned communities throughout Forsyth County, all of which benefit from professional pressure washing and exterior cleaning services. Thrare Contracting serves Cumming and Forsyth County with commercial-grade pressure washing for both residential and commercial properties.
Cumming's rapid growth means a large proportion of its residential inventory is relatively new — built between 2000 and the present day — with exterior materials like Hardie plank fiber cement, full-brick and brick-and-stone veneer, vinyl siding, and stucco that are all vulnerable to Georgia's biological growth conditions. The proximity to Lake Lanier along Forsyth County's eastern boundary creates elevated humidity levels throughout much of the county. Combined with the heavier rainfall that Cumming receives compared to areas further south, and the substantial tree canopy in established subdivisions, the conditions for algae, mold, and mildew growth on exterior surfaces are consistently favorable throughout the year.
Many Forsyth County homeowners do not realize how much biological growth has accumulated on their siding and roofs until they see a professional cleaning result. The dark staining, green algae patches, and gray mold streaks that develop gradually over months and years become the new baseline for what a house looks like — until it is professionally cleaned and the original color is restored. Thrare Contracting provides that transformation for Cumming homeowners, using professional soft wash systems and commercial-grade cleaning chemistry that delivers results lasting significantly longer than DIY or consumer-grade approaches.
The homes in Cumming's planned communities tend to be larger than average for the Atlanta metro, with many properties featuring two- and three-car garages with large concrete aprons, extended driveways, expansive rear decks or screened porches, and multiple gable and dormer roof planes — all of which accumulate biological growth and staining. A complete exterior cleaning of a large Forsyth County home is a significant undertaking that requires professional equipment and crew coordination to do thoroughly and efficiently.
Our house washing service for Cumming homes uses a professional soft wash system that is appropriate for all the exterior materials commonly found in Forsyth County construction. Hardie plank fiber cement — one of the most popular siding choices in newer Atlanta-area construction — has a factory-applied paint finish that requires careful, low-pressure cleaning to avoid paint damage. Our soft wash approach applies cleaning solution at low pressure to kill algae, mold, and mildew without any risk of stripping the paint coating. For the brick and stone veneer elements common on Cumming homes — around garage entries, at front elevations, and on chimneys — we use masonry-appropriate pressure levels that clean thoroughly without mortar damage.
Long driveways are a defining feature of Forsyth County living, and our driveway cleaning service is one of the most requested in the Cumming area. A 60- or 80-foot concrete driveway that has turned dark green with algae and stained gray with tire marks and environmental deposits is a significant visual detractor from an otherwise well-maintained property. We use commercial rotary surface cleaners that cover large areas quickly and evenly, combined with pre-treatment for any specific stain types. The transformation of a large Cumming driveway from stained to clean is one of the most dramatic improvements we provide — and many homeowners tell us it looks better than it did when the concrete was first poured.
Roof cleaning is particularly important in Cumming due to the combination of rainfall, tree shade, and Lake Lanier's influence on local humidity. The black algae streaking that affects asphalt shingle roofs is widespread throughout Forsyth County, and on a large home with multiple roof planes and significant square footage, the visual impact of an algae-streaked roof can dramatically affect the home's curb appeal and perceived value. Our roof cleaning service uses the industry-standard soft wash approach — low-pressure application of professional algaecide — to eliminate the Gloeocapsa magma algae causing the staining. We never use high pressure on shingles, and we protect surrounding landscaping throughout the cleaning process.
Cumming's newer large homes also tend to have more extensive deck and outdoor living areas than homes in older Atlanta suburbs. Large rear decks, covered outdoor kitchens, screened and enclosed porches, and elaborate patio and pool deck areas are common in Forsyth County's higher-end subdivisions. We clean wood and composite deck surfaces to remove embedded biological growth and gray weathering, preparing them for restaining or sealing. For stone pavers, stamped concrete, and standard concrete patio areas, our surface cleaner equipment provides even, thorough cleaning that removes years of staining and biological growth without the unevenness that pressure wand application alone can produce.
Gutter cleaning is another high-demand service in Cumming, where the heavy tree canopy in established subdivisions deposits leaves, pine needles, and organic debris into gutters at significant rates. Clogged gutters cause water to overflow and run down home exteriors — staining siding, damaging fascia boards, and potentially causing water intrusion issues at the foundation. Our gutter cleaning service removes all interior debris, flushes downspouts completely, and optionally brightens the exterior of gutters to remove the dark oxidation and tiger-stripe staining that accumulates on white aluminum gutters over time.
Cumming's rapid residential growth has driven parallel commercial development along the GA-400 corridor, the GA-20 corridor through Forsyth County, and the emerging downtown area. Major retail centers, medical office parks, restaurant districts, and the Cumming City Center mixed-use development have all added significant commercial inventory that requires professional exterior maintenance. Thrare Contracting provides the full range of commercial exterior cleaning services for Forsyth County business properties.
Our commercial pressure washing services in Cumming and Forsyth County include building exterior washing for all facade types, parking lot and parking deck cleaning, sidewalk and plaza maintenance, dumpster enclosure degreasing, and loading dock hot-water cleaning. For the medical office parks that have proliferated along the GA-400 corridor near the Northside Hospital Forsyth campus, clean building exteriors and sidewalks are part of maintaining the professional environment that healthcare facilities require. We can provide recurring maintenance programs with the documentation and compliance requirements that large healthcare property managers need.
The Cumming restaurant scene has grown substantially along GA-20, Market Place Boulevard, and the Cumming City Center, and all of these food service operations need specialized exterior cleaning for kitchen exhaust areas, hood vents, and grease accumulation zones. Our restaurant exterior cleaning service addresses these needs with hot water equipment and commercial degreasing chemistry that standard pressure washing services are not equipped to handle. We work with restaurant operators on scheduling that aligns with their hours — typically early morning before opening or after close — to minimize disruption.
The growing number of apartment and townhome communities throughout Forsyth County requires comprehensive exterior cleaning programs. As Cumming's population has grown, developers have added significant multi-family inventory along Bannister Road, Bethelview Road, and near the GA-400 interchanges. Apartment community pressure washing encompasses building exterior washing, breezeway and stairwell cleaning, pool deck maintenance, and parking area cleaning. We work with property management companies and HOA boards on recurring maintenance schedules that maintain community appearance and reduce long-term maintenance costs.
