Deck Post Repair Costs Explained: Fixing, Replacing, and Identifying Load-Bearing Posts
Homeowners in Atlanta ask us the same set of questions every spring: What will it cost to fix my deck posts? Can I repair the posts I have, or do they need to be replaced? How can I tell which posts are actually holding the structure up? These are smart questions. Posts do more than hold a handrail; they carry vertical loads from beams and joists into the ground. If a post is failing, the deck can settle, twist, or worse. This article breaks down real pricing ranges we see across the Atlanta area, explains when a repair makes sense, and shows you how a pro identifies the posts that matter most.
If you are searching for deck post repair near me, you are likely dealing with a real issue under your feet. Use this guide to get your bearings, then reach out for a quick site assessment. Heide Contracting services Atlanta, Decatur, East Atlanta, Kirkwood, Buckhead, Sandy Springs, Brookhaven, Smyrna, and nearby neighborhoods. We quote promptly and fix posts the right way, so your deck stands straight and safe.
Why deck post problems cost what they cost
Costs follow risk, time, and access. A post that supports a heavy, two-story deck in Buckhead demands more shoring and heavier hardware than a short landing at a townhome in Virginia-Highland. Soil conditions vary across Atlanta. In some lots near the Chattahoochee, we see sandy fill that doesn’t hold a footing as well as native red clay in Decatur. The deeper we have to go to find bearing, the more it costs. Finishes and height matter too. A 12-foot post for a second-story deck needs bracing and longer stock, so labor and material both rise.
Hidden damage is the wild card. Rot often starts at grade, inside a post set directly in concrete without a proper standoff. From the outside the post looks fine, but a screwdriver test at the base sinks in. We budget for these findings and build time to shore the frame before we cut. That careful approach keeps people safe and prevents sagging while we work.
Typical cost ranges in Atlanta for deck post repair
Most homeowners want a straight number. Here is what we see in real jobs around Atlanta. These are ballpark ranges for a single post and common scenarios. Multi-post projects often run more efficiently per post.
-
Simple base repair with bracket retrofit: $350–$700. This is where the post is sound above grade, but the base needs a standoff bracket and hardware upgrade. It fits low decks where access is straightforward and the footing is solid.
-
Partial post splice above grade: $600–$1,200. We cut out the lower rot, install a new section with a structural scarf or half-lap, then add a galvanized standoff and through-bolts. This only works if enough of the upper post is still strong and code allows an engineered splice.
-
Full post replacement on existing footing: $900–$1,800. This includes temporary shoring, removal, setting a new pressure-treated post, installing a code-rated base connector, and through-bolting to the beam with new hardware. Taller posts and tighter access push this higher.
-
Full post and new footing: $1,600–$3,500 per post. Needed when the footing is undersized, heaved, or missing. Pricing depends on depth, site access, and whether we pour a spread footing, use a precast pier, or install a helical pile. Steep lots in neighborhoods like Morningside or Druid Hills tend to land on the higher side due to access and slope.
-
Structural correction with beam lift and multiple posts: $3,000–$9,000+. This is where we realign a sagging beam, replace several posts, and add brackets, lateral bracing, and uplift connectors. It restores proper load paths and often extends the life of an older deck by years.
Hardware, finish cuts, disposal, and permits can add to the total. The City of Atlanta and many surrounding municipalities want permits for structural post replacement, especially when foundations are involved. We handle the paperwork and schedule inspections so the job passes cleanly.
Fix or replace: how we decide on the right approach
We start with two questions. First, is the post still carrying full load without crush, rot, or splitting? Second, is the path from beam to soil continuous and code-compliant? If the answer to either is no, replacement usually makes more sense than a patch. Repairs like splices are possible when the remaining wood is dry and strong, the rot is isolated above grade, and the joint can be reinforced with solid blocking and steel plates or straps.
Safety drives the decision. If a post is checked along the grain with visible movement under load, a splice won’t restore full strength. If termites have tunneled inside the low section, the damage tends to extend farther than you see. In those cases we replace with new pressure-treated Southern Yellow Pine, rated for ground contact, and we pair it with a hot-dipped galvanized or stainless base that keeps the wood off concrete. That simple detail stops repeat failures.
Occasionally, we fix the problem without touching the post at all. If a post leans because the beam connection is loose or the base bracket is undersized, upgraded hardware, a beam seat, or a lateral brace brings it back into square. This can be a lower-cost solution if the wood is in good shape.
How to identify load-bearing posts on your deck
A load-bearing post supports beams or girders, which support joists and decking. A non-load post usually holds a handrail or privacy screen. On site, we verify with a few checks. We look for the post at a beam intersection or directly under a girder. If the post lines up with the end of joists or sits under a splice in the beam, it is load-bearing. Railing posts that bolt to the rim and never touch a footing are non-load. Sometimes a post appears decorative but hides structure inside a boxed column. We remove a trim board to confirm.
Inside corners and stair landings can mislead homeowners. Stair posts often carry both railing and landing loads. They need solid blocking, through-bolts, and proper deck and porch repair services tread attachment to prevent racking. We treat these as structural even if they look small.
If the deck covers a patio or slopes away from the house, we track the load down to the soil. A true load post should land on a poured footing or a rated pier, not on pavers, patio slabs, or soil alone. If we find a post bearing on thin concrete or settled fill, we plan a new footing or a helical pile. Both spread the load and stop settlement.
What drives price differences between neighborhoods
Local conditions across metro Atlanta affect labor time and materials. In-town lots often have tight side yards, fences, and mature landscaping. That means hand-digging footings, carrying out debris, and setting up shoring without machinery. In suburbs like Sandy Springs or Smyrna, access tends to be easier, which lowers labor hours. Soil composition matters too. Red clay holds shape for a cleaner hole, while sandy loam caves in. Shoring a hole adds time.
We also see a range of hardware on older decks. Many mid-2000s builds used nails and undersized brackets for posts and beams. Upgrading to through-bolts, Simpson Strong-Tie brackets, and lateral load connectors raises material cost a bit, but it prevents movement and meets current codes. Finally, code compliance varies by city. Brookhaven, Decatur, and the City of Atlanta each have their own permit thresholds and inspection steps. We price with those steps in mind so your job stays compliant.
Common post failures we see in Atlanta
The same patterns repeat. Rot at grade is the top culprit. Posts set directly in concrete wedge water against the wood, and Georgia humidity sustains decay fungi. Freeze-thaw cycles are mild here, but enough to open hairline gaps that let water in. Termite activity is another frequent find, especially where mulch touches the post or a deck sits near an old stump. We also see crush failures at the beam connection. A post that supports a heavy hot tub load or a big spanning beam will compress at the top over time if the bearing area is small or the cut is not square.
Lean and sway point to missing bracing. Tall decks, especially those over 8 feet, need diagonal bracing in both directions. Without it, the structure racks in wind and during use. That movement loosens connections and speeds up failure. Hardware corrosion is a slower problem. Decks near pools or grills can expose galvanized hardware to chlorides or heat, which accelerates rust. When a bracket flakes or bolts show heavy corrosion, we replace them with heavier grade hardware.
Repair methods that work and what they cost
On a site visit, we judge wood condition, bearing, and connections. For a post with minor base rot but a sound top, we cut the post square above the decay line and install a solid splice. We glue and screw the joint, add steel side plates or a structural strap across the seam, then set the lower section on a standoff base attached to a verified footing. Expect $600–$1,200 depending on height and access.
If the base is sound but the top is crushed or split at the beam, we lift the beam with a jack and a crib stack, trim the post to a clean surface, add a steel cap or increased bearing plate, and reinstall with through-bolts and a seat bracket. This lands around $500–$900. It is an efficient fix that restores bearing and removes play.
For a full replacement, we shore the beam, remove the post, check the footing, and install a new post with a hot-dipped galvanized base. We plumb the post, fasten with through-bolts, and add blocking as needed. If the deck carries high loads or sits above 8 feet, we usually add diagonal bracing. Expect $900–$1,800 if the footing is sound.
When the footing fails or is missing, we dig a new one to 12–24 inches diameter and 24–36 inches deep, or deeper if required by soil and code. In many Atlanta soils, 24–30 inches depth gives good bearing. We set a rebar cage, pour concrete, and install a post base after cure. This is a two-visit job and runs $1,600–$3,500 per post. On slopes or restricted access sites, a helical pile is a smart choice. We drive it with a compact torque motor to a verified load, then mount a post bracket. Helicals cost more upfront but save on excavation and cure time, and they perform well in variable soils.
How we figure out which posts to tackle first
Budgets matter. We prioritize posts that carry high loads, show active movement, and have decay at grade. Mid-span beam posts are high priority, especially under heavy-use zones like dining areas or hot tubs. Corner posts matter for bracing and uplift resistance. We rate posts during the assessment and recommend a phased plan if needed. Addressing two or three critical posts can stabilize the structure and buy time for less urgent work.
We also look for code red flags. If any post is toe-nailed into a beam without a bracket, or if a post sits directly on soil or a patio slab, we mark it for correction. These conditions fail inspections and create real risk. Upgrading hardware and raising the post onto a proper base is quick and makes a big difference.
How to tell if you can wait or if you should act now
There are simple signs you can check before calling. Watch for a gap opening at the top of a post where it meets the beam. If the beam drops away from the post, the connection has loosened. Stand back and sight the line of the beam. A visible dip over a post suggests crush or a footing issue. Probe the base of the post with a screwdriver. If it sinks more than a quarter inch into soft wood, rot has set in. Leaning more than a degree or two is also a concern, especially on tall decks.
We recommend an inspection right away if your deck supports a grill zone, spa, or large gatherings. Load clusters raise risk on marginal posts. In many cases, we can shore and fix a failing post in a day. That quick action prevents a more expensive structural repair later.
Materials, hardware, and code: what a proper repair looks like
In metro Atlanta we build with pressure-treated Southern Yellow Pine rated for ground contact where the post is near grade. Posts are often 6x6 for real load capacity and better connection options. A 4x4 is common on older decks but is prone to twist and crush in high loads or tall heights. Hardware should be hot-dipped galvanized at minimum. Near pools or coastal exposures, stainless steel is worth the upgrade. We use structural screws or through-bolts for primary connections, not nails.
Bases matter. A code-rated post base lifts the wood off concrete by at least half an inch. That break keeps the end grain dry. We attach the base to the footing with a cast-in anchor or an epoxy-set anchor rod. For uplift resistance, we add post-to-beam straps or hold-downs per manufacturer specs. Diagonal braces go in both directions on tall decks to stop sway. These details cost a bit more upfront and pay back with longer life and fewer callbacks.
Permits are part of structural work. The City of Atlanta, Decatur, and other jurisdictions require a permit for post replacement and footing work. We submit drawings that show footing size, post size, hardware, and bracing. Inspectors appreciate clean, code-based plans. It makes approvals straightforward and protects your investment.
How long repairs take and what to expect
A single post repair usually takes half a day to a full day. Full replacements with a new footing often run two visits: one for excavation and pour, another after cure to set the post. Helical piles shorten that to a single visit in many cases because there is no cure time. Multi-post projects span one to three days depending on count and access.
We set up temporary supports under the beam before we touch a post. You will hear the beam lift a fraction as we take weight; that is normal. We keep the deck usable where possible, though we block off the work area for safety. If we pour new footings, we mark off the wet concrete overnight. At the end, we sweep up and haul away debris, then walk you through the hardware so you know what was done and why.
DIY versus hiring a pro
Some homeowners are handy and can replace a short railing post or retrofit a bracket on a low deck. Structural posts are different. The risks include sudden beam drop, personal injury, and latent failure that shows up months later. Shoring needs to be strong and set on stable ground. Cuts must be square, and bearing must be full. Hardware has to match the loads. And if you are in Atlanta or a surrounding city, the inspector will want to see permitted work on structural posts and footings.
We encourage DIYers to handle maintenance tasks like clearing soil and mulch away from posts, cleaning leaves from base brackets, and checking for loose bolts. For anything structural, call a contractor with post and footing experience. The cost of a proper repair is usually less than the cost of redoing a failed fix, and it protects your family and your home.
Preventing post problems before they start
Simple care adds years to a deck. Keep 2 inches of air space around post bases. Don’t pile mulch, soil, or river rock against the wood. Make sure downspouts do not dump water near footings. On sloped yards in neighborhoods like Grant Park or Candler Park, consider a small swale or dry well to move water away from posts. If your deck has skirting, add vents so air can circulate. Annual checks for loose hardware and a quick probe at the base of each post catch issues early.
If your deck is older than 15 years, consider a hardware refresh. Replacing rusted brackets, adding lateral bracing, and installing standoff bases on posts sitting on concrete will reduce movement and moisture exposure. These upgrades cost less than a major rebuild and push out the timeline for big repairs.
Budget planning and real examples
Here is how numbers play out in the field. We replaced two 6x6 posts on a 10-foot-high deck in Brookhaven. The footings were intact, but the posts were set directly on concrete and had rot at the base. We shored the beam, cut and replaced both posts, added standoff bases, through-bolts, and diagonal bracing on one bay. The job took one full day with two techs. Total cost: $2,350.
In Decatur, a homeowner called about a dip at mid-span. We found a crushed top on one 6x6 under a splice in the beam. The footing was solid. We lifted the beam a half inch, trimmed the post, installed a steel bearing cap, and added a heavy seat bracket with through-bolts. We also added two structural screws to lock the beam plies. The fix took three hours. Total cost: $680.
In East Atlanta Village, we corrected a landing with a post bearing on pavers. We installed a 24-inch square footing at 30 inches depth, set a new base, and replaced the short 4x4 with a 6x6. We tied it into the beam with a strap and added blocking. Two visits with cure time. Total cost: $1,850.
These are representative, not promises. Your site, soil, access, and code requirements set the final number. We scope clearly and keep you informed.
How to get an accurate quote in Atlanta
Two things help us price quickly and accurately. First, clear photos of the post base, the post-to-beam connection, and a wide shot of the deck from the yard. Second, rough measurements: deck height, post size, and any signs of movement. If you are comfortable, do a quick probe at the base with a screwdriver and note if the wood is soft.
We schedule on-site visits across Atlanta, Sandy Springs, Smyrna, Brookhaven, Decatur, and neighboring areas. We check every load path, test for movement, and identify which posts are load-bearing. Then we lay out options: repair, replace, or full footing. You get a firm quote, a schedule, and a clean scope.

FAQs we hear from Atlanta homeowners
Do I need a permit to replace a deck post? In most Atlanta-area jurisdictions, yes for structural posts and footings. We handle the permit and inspection process.
Can you repair a rotted post without replacing it? Sometimes. If rot is limited and the remaining wood is strong, a reinforced splice above a proper standoff base works. If rot wraps around the post or extends up the grain, replacement is safer.
How long will a new post last? With a standoff base, proper hardware, and good drainage, a pressure-treated 6x6 can serve 15–25 years or more in Atlanta’s climate. Maintenance and water control make the biggest difference.
What about metal posts? Steel posts perform well and resist rot, but they need proper coatings and hardware. They shine on tall decks and heavy loads. Costs are higher upfront. We install them when the structure calls for it.
Will insurance cover a failed post? Policies vary. Sudden damage from a storm might be covered. Gradual rot is usually not. We can document conditions for your adjuster.
