Expert Deck Washing & Wood Restoration for Cobb County Homes
Marietta is one of Atlanta's great historic suburbs — a city with deep roots, a thriving downtown square, and neighborhoods that range from Victorian-era bungalows to sprawling modern estates on the slopes of Kennesaw Mountain. Outdoor living is woven into Marietta's culture. Residents spend weekends on their decks, host neighbors for cookouts, and use their outdoor spaces year-round thanks to Georgia's relatively mild climate. When a deck starts looking gray, slimy, or stained, it diminishes not just the aesthetic of your home but the enjoyment of your outdoor lifestyle. Rare Earth Ltd restores Marietta decks to their original beauty with professional cleaning and preparation services.
Cobb County sits northwest of Atlanta, and Marietta is positioned near the base of Kennesaw Mountain. This geography creates microclimates that can accelerate deck deterioration. The rolling terrain and mature tree canopy in neighborhoods like East Cobb, West Marietta, and the communities near Lost Mountain Road mean many decks spend significant time in shade — exactly the condition that encourages biological growth. A shaded deck can develop visible mold and algae within a single summer season if left without treatment or regular cleaning.
Even decks in full sun face challenges. UV radiation bleaches wood rapidly in Georgia's intense summer light, breaking down lignin — the natural polymer that gives wood its structure and color — and leaving behind a weakened gray surface. Combined with the seasonal humidity that keeps moisture on surfaces for extended periods, Marietta decks need professional attention every one to two years to maintain their appearance and structural integrity.
Marietta has a significant stock of older homes, and many of the decks on these properties were built with materials and methods that are no longer standard. Some feature redwood, which was commonly used in higher-end deck construction before it became cost-prohibitive. Others have older pressure-treated pine that was treated with CCA (chromated copper arsenate), a formulation discontinued in residential applications in 2003. These older decks often have years or even decades of built-up weathering, multiple layers of old stain, and deep biological staining in the wood grain.
We have experience working with older deck materials and understand the appropriate cleaning chemistry and technique for each. For decks that need stripping and brightening before refinishing, we offer comprehensive preparation services. For decks that simply need a thorough cleaning, our process restores the surface without damaging wood that may already be showing signs of age. We assess each deck individually and recommend the right approach for its specific condition and material type.
East Cobb is one of metro Atlanta's most affluent suburban corridors, and its newer construction frequently features composite decking products from brands like Trex, TimberTech, and Fiberon. These homes were built with outdoor entertaining in mind — large rear decks, screened porches, and multi-level outdoor living areas are common throughout the East Cobb communities of Walton, Lassiter, and Pope school districts. As these composite decks age, they accumulate mold, tannin staining from tree debris, and the green algae that is ubiquitous in Georgia's humid climate.
Cleaning composite decking requires discipline. High-pressure washing damages the board surface and can strip protective coatings. Chlorine bleach is effective on mold but can bleach and discolor certain composite formulations. We use composite-manufacturer-approved cleaning chemistry and appropriate pressure to restore these surfaces safely. Our goal is always to deliver results that meet or exceed the deck manufacturer's own maintenance recommendations.
One of the most common requests we receive from Marietta homeowners is preparing a deck for staining or sealing. Whether you plan to hire a painter or do the staining yourself, the quality of the final result depends almost entirely on how well the surface was prepared. Stain applied to a dirty, gray, or mold-contaminated surface will peel and fail within a single season. Stain applied to a properly cleaned and brightened surface can last five to seven years with minimal maintenance.
Our stain-prep service includes a thorough cleaning followed by a wood brightener application. Brightening treats the gray oxidation on the surface, restoring the natural wood color and opening the grain slightly for better stain penetration. The result is a surface that stain manufacturers consider ideal for application — clean, brightened, and ready to accept finish. Many contractors in the metro Atlanta area will not honor stain warranties unless the surface was properly prepared before application.
