Your Local Deck Washing & Restoration Specialists — Based Right Here in Stone Mountain
Thrare Contracting is based right here in Stone Mountain, Georgia — which means when you call us for deck cleaning, you are calling your neighbors. We know this community firsthand. We know the neighborhoods, the housing stock, the way the woods and creek corridors that run through Stone Mountain create shaded, humid microclimates that make deck maintenance a real ongoing challenge. We are not a franchise passing through; we are a locally owned minority business that is invested in the quality and reputation of every job we complete in our own backyard.
Stone Mountain's residential areas offer a tremendous variety of home styles and corresponding deck configurations. The older neighborhoods in the western and central portions of the city — some dating to the 1960s and 1970s — feature mature trees, large lots, and the kind of canopied backyard environments where decks age quickly without regular attention. Newer developments along the city's growth corridors include recently built decks with composite and pressure-treated materials that nonetheless need cleaning to look their best and to protect the investment the homeowner made. We bring the same professional approach to every deck we clean, regardless of age or material.
Stone Mountain's proximity to the Stone Mountain Park and the surrounding green space corridors means the city has more tree canopy than many comparable suburban communities. That canopy is one of Stone Mountain's defining characteristics — mature oaks, sweet gums, hickories, and pines create beautiful shade and a distinctive wooded character. But for decks, that canopy is a constant source of maintenance challenge.
Leaves fall onto deck surfaces and decompose, depositing organic matter that feeds algae and mold while the wet, compressed leaf mass holds moisture against the wood or composite surface for extended periods. Overhanging branches drop sap, seed pods, and smaller debris continuously through the growing season. The shade created by the canopy keeps surfaces damp long after rain events — a shaded deck in Stone Mountain can stay wet for 24 hours or more after moderate rain, compared to an exposed surface that dries within an hour. That extended moisture exposure is what drives the aggressive biological growth that Stone Mountain homeowners frequently notice on their decks.
Pollen is another factor. Georgia's pollen season — one of the most intense in the country — deposits a thick yellow coating on every outdoor surface from February through May. Pollen on a deck surface is not merely cosmetic; it is a sticky, protein-rich biological material that serves as food for the microorganisms that drive biological growth. A deck that is not cleaned after pollen season has a head start on the algae and mold development that will accelerate through the summer months.
The majority of decks in Stone Mountain's residential neighborhoods are constructed from pressure-treated pine — the industry standard for deck construction for decades. Pressure-treated pine is durable and cost-effective but requires consistent maintenance to look good and last long. Without regular cleaning, pressure-treated pine develops the characteristic gray weathered appearance that signals oxidation and biological growth have taken hold. The gray color itself is not necessarily structural damage, but the conditions that produce it — retained moisture, biological colonization, UV exposure — are progressive and will shorten the deck's life if unaddressed.
We clean pressure-treated pine using a combination of controlled pressure washing and professional deck cleaning chemistry. The chemistry penetrates the wood grain and breaks down biological growth at a cellular level, lifting mold, algae, and mildew from within the wood fibers rather than simply washing the surface. The pressure washing that follows rinses the chemistry and loosened contamination cleanly from the surface. The result is wood that is genuinely cleaned, not just surface-washed. For homeowners considering staining or sealing after cleaning, we leave the surface prepared to stain-manufacturer standards — the right moisture content and cleanliness for maximum finish adhesion and longevity.
Composite decking — Trex, TimberTech, Fiberon, and similar products — has become increasingly popular in Stone Mountain's newer homes and in deck replacement projects across the city. The appeal is understandable: composite resists rot, splinters, and insect damage, and the manufacturers market it as low-maintenance. But Stone Mountain's climate tests that claim. The textured surface of most composite products provides microscopic surface area for biological growth to grip, and the groove pattern of many composite boards channels water and debris into ideal conditions for mold and algae development.
Composite decks in Stone Mountain, particularly those on shaded lots, develop the same green and black biological staining that affects wood — it simply appears differently on the smooth surface. Many homeowners are surprised to discover that what they assumed was permanent staining on their composite deck lifts completely with professional cleaning. The key is using the appropriate cleaning chemistry for composite materials — many wood deck cleaners are incompatible with composite products and can cause surface discoloration or damage. We use products specifically formulated for composite materials, maintaining manufacturer warranty compliance while delivering complete biological stain removal.
A comprehensive deck cleaning addresses more than just the walking surface. Deck stairs accumulate the same biological growth as the deck surface, plus the additional soiling that comes from foot traffic bringing in soil and organic matter from the yard below. Handrails — particularly flat-topped rails that hold standing water — develop significant biological growth and can become slippery and unsafe. The deck understructure and the ground-level area beneath the deck accumulate debris, organic matter, and moisture that can become a source of ongoing biological contamination affecting the deck surface above.
We include stairs, rails, and visible understructure surfaces in every deck cleaning we perform. The result is a comprehensive clean that addresses the entire outdoor structure rather than leaving adjacent surfaces in contrast to the freshly cleaned deck surface. For Stone Mountain homeowners who also have attached screened porches, we clean porch floors, screening frames, and ceiling surfaces as part of an extended scope that addresses the entire outdoor living structure.
Many Stone Mountain decks have not been cleaned in multiple years, and first-time professional cleaning of a neglected deck reveals results that motivate homeowners to maintain the schedule going forward. We recommend annual cleaning for most Stone Mountain decks as a baseline, with semi-annual cleaning for heavily shaded decks or decks on properties with very dense tree canopy. Regular cleaning is dramatically more effective and economical than attempting to restore a deck that has been neglected for an extended period and has deep-set staining or early rot conditions developing in damp corners.
