A significant number of Marietta’s East Cobb, West Cobb, and Kennesaw Mountain neighborhood homes were built between 1980 and 2000 — an era when poured concrete was the standard patio material for suburban Atlanta construction. Those slabs are now 25–40 years old, and they are showing exactly what Cobb County’s clay soil does to rigid concrete over decades: they are cracked, unevenly settled, stained with algae and rust, and in many cases tilted slightly away from their original plane. The question most Marietta homeowners are asking is not whether to do something about it. The question is whether to repair the concrete or replace it with pavers.
We’ve done both types of projects in Marietta. Here’s the honest answer: in almost every scenario involving a slab that’s more than 15 years old and showing cracks, resurfacing or patching buys two to four years before the same problems reappear. Replacement with pavers addresses the root cause and produces a surface that will outlast the house. The cost difference between the two paths is real — but so is the difference in what you’re buying.
Why Marietta Slabs Fail
Marietta’s residential neighborhoods sit on a mix of Piedmont clay and weathered granite — soils that swell and contract dramatically with moisture variation. A concrete slab poured in 1990 was installed on soil that was reasonably stable at the time of pour. Thirty-five years of wet seasons and dry seasons later, the soil beneath that slab has cycled through hundreds of expansion-contraction events. The slab, being rigid and monolithic, doesn’t accommodate those movements — it transmits them as stress until the stress exceeds the concrete’s tensile strength and a crack forms.
The first crack is typically diagonal, running from a corner, or following a control joint that was inadequately placed or cut too shallow. Water enters the crack, freezes in winter (even Atlanta’s mild winters produce occasional frost), expands, and widens the crack. Roots from nearby trees and shrubs find the crack, grow beneath the slab, and accelerate heaving. By the time a Marietta homeowner is looking at a slab with multiple cracks, corner settlement, and visible height differentials between sections, the underlying soil condition that produced those failures has not changed — and any surface repair applied on top of that slab is working against the same forces that failed it the first time.
“Resurfacing a failed concrete slab is a cosmetic fix on a structural problem. The surface gets new. The root cause stays exactly the same.”
Repair vs. Replace
Concrete resurfacing in Marietta typically costs $3–$6 per square foot — $1,200–$2,400 for a standard 400-square-foot patio — and looks reasonably good for two to three years before the underlying cracks telegraph back through the surface layer. Some resurfacing products hold longer if the substrate is stable, but a slab with active settlement or significant cracking is not a stable substrate. The resurfaced version of that slab is buying time, not solving the problem.
Concrete demolition and removal runs $2–$4 per square foot in Marietta, meaning a 400-square-foot slab costs $800–$1,600 to break up and haul away. Add paver installation at $15–$25 per square foot and you’re looking at a total project of $16,000–$26,000 for a properly installed 400-square-foot paver patio — versus $1,200–$2,400 for resurfacing that will need to be redone in 3 years. Over a 15-year period, the homeowner who resurfaces twice and then replaces will have spent more total, with more disruption, than the homeowner who replaced upfront.
The functional differences are also meaningful. A paver surface is individually repairable — if a single unit settles or cracks, it can be pulled, the base re-leveled, and the unit reset in an hour. A concrete slab cannot be partially repaired without a visible patch. The pavers also look categorically different — warmer, more textured, more intentional — in a way that concrete resurfacing cannot replicate regardless of finish applied.
The Removal & Install Process
The sequence for a concrete removal and paver installation project in Marietta’s backyard neighborhoods is more involved than a standard paver install on bare ground, and homeowners should understand the scope before committing:
Homeowners who have lived with cracked, stained, grey concrete for years are consistently surprised by how different the paver replacement reads. The scale change alone — moving from large grey panels to a field of individual units with consistent joint lines — transforms the perceived size and character of the outdoor space. Concrete reads as infrastructure. Pavers read as design. The same square footage of paver patio commands more attention in listing photos, more compliments during gatherings, and more return in resale perception than an equivalent concrete surface — even a fresh one.
Functionally, the surface drains better — joint sand allows water to infiltrate and disperse rather than sheet-flowing across the surface — which eliminates the standing water and algae conditions that make old concrete dangerous and ugly in Marietta’s wet seasons. The texture of paver surfaces also provides better slip resistance in wet conditions than brushed or broom-finished concrete, which matters on a surface being used for outdoor dining and entertaining.
What It Costs
For Marietta homeowners planning a full concrete demo and paver replacement, the combined project typically runs $14,000–$28,000 for standard sizes (300–500 square feet) with concrete paver material. Travertine or porcelain upgrades add $4,000–$10,000 to that range. Across North Georgia, paver patios run $8,000–$35,000+, with Alpharetta and Milton projects typically pricing 20–40% above the Marietta baseline due to material preferences and drive time. For Marietta homeowners, the relevant comparison isn’t the cost of a paver replacement versus nothing — it’s the cost versus a resurfacing cycle that will repeat every 2–4 years until the slab is replaced anyway.
A concrete replacement project in the Marietta area — demo completed, base compacted, pavers installed on a properly prepared system that won’t repeat the failures of the slab it replaced.
Concrete replacement projects are a different discipline than standard paver installation. The demolition phase introduces variables — existing drainage infrastructure, edge conditions at the house, root intrusion in the subgrade — that don’t exist on a raw ground installation. We assess all of those conditions before we quote, because a quote that doesn’t account for subgrade remediation is quoting a project that may require unplanned work mid-job. That’s not a conversation we want to have at the halfway point, and it’s not a surprise you want to absorb once the demo crew is already there.
