Walk through the older neighborhoods near downtown Marietta and the Square, then drive out toward Sandy Plains Road or the newer streets closer to Kennesaw, and you'll see the same thing: wood is still the default deck material for most Cobb County homeowners. It costs less to build than composite, it looks like it belongs on a Georgia house, and it gives you a surface you can refinish in a new stain color whenever you want a change instead of living with whatever color you picked years ago.
We build custom pressure-treated pine and cedar decks from the ground up — footings, framing, decking, railing, and stairs — designed around your actual lot rather than a stock plan. That matters more here than people expect, because Cobb County's terrain and soil are not uniform. A flat lot near Town Center at Cobb builds very differently than a sloped backyard near Kennesaw Mountain National Battlefield Park, and we design for the lot in front of us.
Pressure-Treated Pine vs. Cedar
Pressure-treated pine is the workhorse of Marietta deck building. It's affordable, structurally strong, and available in dimensions that make quick work of long spans and tall support posts on sloped lots. Once it's sealed, it holds up well through our summers and winters both. The trade-off is that it needs a fresh coat of sealant every year or two, and left unsealed it will gray and check faster than most homeowners expect.
Cedar is the upgrade option. It resists rot and insects on its own, takes stain evenly, and tends to stay straighter in Georgia's humidity than pine does. It costs noticeably more, which is why we usually frame the structural parts of a cedar deck in pressure-treated lumber and reserve the cedar for the decking boards, railing, and any trim that's actually visible — you get the look without paying premium prices for lumber nobody will ever see.
Building on Cobb County's Red Clay
Our soil is not forgiving of shortcuts. Red clay swells when it's wet and shrinks hard when it dries out, and a footing that isn't poured deep enough or sized for the load above it can shift over a few seasons, which shows up later as a deck that feels slightly off level or a post that's started to lean. We dig every footing below the frost line and size it to the actual structure and soil conditions on your property, not a generic minimum. It's the least visible part of the job and the part we're least willing to cut corners on.
Permits, Georgia Building Code, and City of Marietta Inspections
An attached deck almost always needs a permit, whether you're inside Marietta city limits or in unincorporated Cobb County, and that permit comes with footing and framing inspections along the way. We handle the entire process — drawings, the permit application, scheduling inspections, and making sure the finished deck actually meets Georgia's wind and snow-load provisions for our region — so you're not the one making calls to City Hall mid-project. If you're weighing what a project like this actually costs once permits and materials are factored in, our deck cost guide for Marietta homeowners breaks that down line by line.
HOA Approval in East Cobb
A lot of East Cobb subdivisions run architectural review boards with specific rules on railing style, stain color, and setback from property lines. We've been through this process enough times to design a deck that satisfies those guidelines from the first sketch, and we'll put together whatever drawings or material specs your HOA's board wants to see, which keeps a submission from stalling your timeline for weeks.

Design Details That Make a Deck Feel Custom
The difference between a deck that looks like it was always part of the house and one that looks tacked on usually comes down to a handful of details: matching the fascia to your siding, choosing a railing profile that fits the home's architecture instead of the cheapest option on the shelf, and getting stair proportions right so they feel natural to walk instead of slightly too steep. We spend time on these details on every project, whether it's a straightforward single-level deck or a multi-tier layout stepping down a sloped backyard.
Wood also gives you options composite can't match as easily — picture frame decking patterns, custom built-in bench seating, planters built into the railing line, or a pergola added later without worrying about matching a discontinued composite color. If low maintenance matters more to you than those options, it's worth comparing against our composite and Trex decking page before deciding.
What Wood Ownership Actually Looks Like Long-Term
Be honest with yourself about maintenance before committing to wood. A sealed deck in full sun needs attention roughly every year to eighteen months; a shadier deck under mature trees can often stretch to two years between treatments. Skip it for several years running and you're looking at graying, splintering boards and, eventually, soft spots that need real repair rather than a simple refinish. If your current deck has already reached that point, our deck repair and restoration team can tell you honestly whether it's a repair or a full rebuild.
For most Marietta homeowners, though, a well-built wood deck with a reasonable maintenance routine lasts fifteen to twenty-five years or more, and refinishing it every so often is a small price for a deck that still looks like it belongs on the house a decade in.
Custom Wood Decks FAQs — Marietta, GA
Most pressure-treated pine decks in the Marietta area run from about $7,000 to $16,000, and cedar decks typically run $14,000 to $28,000 or more, depending on size, framing height, railing style, and stairs. We walk your property and give you a written, itemized estimate before any work starts, and the estimate is free.
Pressure-treated pine costs less up front and holds up well once it is properly sealed, which makes it the more common choice around Cobb County. Cedar costs more but resists rot and insects naturally, takes stain beautifully, and tends to move less in our humidity. We will walk you through both against your budget and how you plan to use the space.
Almost always, yes. The City of Marietta and unincorporated Cobb County both require a building permit for an attached deck, and inspections at the footing and framing stage. We pull the permit, schedule every inspection, and handle the paperwork so you never have to deal with the counter at City Hall yourself.
Red clay expands when it is saturated and contracts hard during a dry spell, which can heave or shift a footing that was not poured deep enough or sized for our soil. We dig footings below the frost line and size them to the load and the soil conditions on your specific lot rather than using a one-size-fits-all spec.
A straightforward pressure-treated deck typically takes 1 to 2 weeks of on-site work once the permit is approved. Larger cedar decks with multiple levels, built-in seating, or elaborate railing can run 3 to 4 weeks. Weather and permit review time both factor in, and we give you a realistic schedule up front, not just a best-case guess.
Yes, when it is built and sealed correctly. We use properly rated fasteners and hardware, install flashing where the deck meets the house to stop water intrusion, and recommend a sealing schedule that accounts for how humid our summers get and the freeze-thaw cycles that come with an occasional Cobb County ice storm.
Plan on a wash and a fresh coat of sealant or stain roughly every 1 to 2 years, more often on a deck that gets full sun most of the day. It is more upkeep than composite decking, but many homeowners prefer the look, feel, and lower upfront cost of real wood and are happy to keep up with it.
Yes. We regularly build decks for historic homes near downtown Marietta and the Square as well as newer construction further out, and we design railing profiles, post details, and stair layouts to fit the house rather than dropping in a generic deck that looks bolted on.
Most East Cobb HOAs have specific rules on railing style, stain color, and how close a deck can sit to a property line. We design within those guidelines from the start and can provide the drawings and material specs most architectural review boards ask for, which keeps the approval process from stalling your project.
Wood costs less initially and gives you a natural look you can restain in a new color down the road, but it needs periodic sealing and eventually shows wear. Composite costs more up front but skips the sanding and staining entirely. If you are weighing the two, our composite and Trex decks page breaks down the trade-offs in more detail.
Yes, and a lot of Marietta properties near Kennesaw Mountain and throughout Cobb County have real grade change in the backyard. We regularly design taller support posts, stepped framing, and multi-level layouts to work with a slope instead of requiring you to regrade the yard first.
Yes, every estimate is free and comes with no obligation. We visit the property, take measurements, talk through what you want out of the space, and hand you an itemized written quote, typically within a day or two of the visit.
