Pool Renovation Cost in Marietta, GA: What Will You Actually Pay in 2026?

Most Marietta homeowners trying to budget for a pool renovation run into the same wall: contractors give vague answers, online calculators spit out national averages, and nobody seems willing to name a real number until they're standing in your backyard. 

Atlanta Leak Pros has spent 13 years working on concrete pools across Marietta and the surrounding area. That experience makes it clear that the pools costing the most aren't always the biggest ones. They're the ones where small problems got deferred until one project turned into three.

Keep reading to find out how much pool renovation costs in Marietta, GA; what each type of renovation work typically includes; what pushes Marietta projects toward the higher end; and how to read a contractor estimate without guessing. 

What Renovation Projects Usually Include

A pool renovation is not just a fresh coat of plaster. Most projects combine at least two or three distinct work categories, and understanding them separately helps you read estimates accurately.

Resurfacing and Finish Replacement

Resurfacing is the most common renovation work, and it involves removing the existing plaster, quartz, or pebble finish and applying a new one directly to the concrete shell. Standard white plaster is the most affordable option, while quartz aggregate and pebble finishes carry higher material and labor costs but last significantly longer in Marietta's hard water conditions. 

Cobb County municipal water typically tests between 220 and 280 ppm calcium hardness, which is meaningfully higher than in Atlanta proper and accelerates surface degradation over time.

The resurfacing process includes draining the pool, prepping and cleaning the shell, applying bonding agents where needed, and finishing with the chosen surface material. Equipment scheduling, weather windows, and cure time all factor into the project timeline.

Crack Stabilization and Structural Repairs

Crack repair is often identified during the drain and prep phase, which is why estimates sometimes include allowances rather than firm numbers for this work. Surface crazing, which looks like a fine web of hairline marks, is usually cosmetic. 

Structural cracks, especially those wider than a credit card or running across the pool floor toward fittings, require grinding, epoxy injection, and, in some cases, hydraulic patching before any new surface can be applied.

In the Marietta area, clay soil movement is a significant driver of structural cracking. Georgia red clay expands when wet and contracts during dry spells, and that ground shift stresses the pool shell in ways that flat-lot pools in other markets don't experience as severely. 

Ignoring a structural crack before resurfacing means your new finish will crack through at the same spot within a few seasons.

Underground Plumbing and Leak-Related Work

Plumbing work is the most expensive line item in many renovation projects, largely because it requires locating the problem before repairing it. If your pool is losing water beyond normal evaporation, a professional underground pool plumbing leak-detection inspection should be conducted before demolition begins. Applying a new surface over an active plumbing leak wastes the entire renovation budget.

Underground plumbing repairs typically involve pressure testing to isolate the line, targeted excavation to access the breach, and either pipe repair or section replacement. This work is not cosmetic and cannot be quoted accurately without an on-site leak inspection first. Once you understand what renovation work your pool needs, the next question is what that work realistically costs.

Typical Price Ranges by Scope

The Marietta market sits roughly 14% below the national labor average, which keeps local bids more competitive than in other metro areas, but scope still drives total cost more than geography does.

Cosmetic Surface Updates

A basic cosmetic renovation, meaning standard plaster resurfacing on a pool in otherwise sound structural condition, typically falls between $4,600 and $9,000 in the Marietta area for a standard residential pool. This assumes no significant crack repair, no plumbing work, and no coping or tile replacement. The pool shell must be structurally sound for this price range to hold.

Upgrading to a quartz aggregate finish adds cost but considerably extends surface life. Pebble finishes carry the highest material cost but are particularly worth evaluating if you've been replastering on a short cycle, since they resist chemical erosion and Marietta's hard-water chemistry better than standard plaster does.

Targeted Repair Packages

When a project combines resurfacing with crack repair, tile and coping replacement, or minor equipment upgrades, the total cost generally ranges from $9,000 to $18,000, depending on the combination. These mid-range projects are the most common scope Atlanta Leak Pros handles in Marietta, because they address the actual condition of most pools that are eight to fifteen years old.

At this scope level, the breakdown of the estimate matters. A thorough bid should separate out:

• Surface preparation and drain/clean costs
  
  
• Material cost by finish type
  
  
• Crack repair or stabilization work
  
  
• Tile and coping replacement if needed
  
  
• Equipment inspection and any replacement recommendations
  
  
• Permit fees and cleanup

Full Structural Overhauls

Full renovations that include structural crack repair, underground plumbing repairs, new tile and coping, equipment replacement, and a premium finish surface can run $18,000 to $32,000 or beyond for larger pools. These projects take longer, require more subphases, and often uncover additional work once demolition begins. 

The average planning cost for Marietta renovation projects is near $13,845, but full structural scopes push well past that midpoint.

What Pushes Pricing Higher in Marietta

Most renovation budget surprises are predictable once you know what to look for. Three factors consistently drive Marietta projects toward the high end of any range.

Pool Size, Shape, and Access Constraints

Larger pools require more material, more labor hours, and longer dry and cure windows. But shape adds cost too. Freeform designs, integrated spas, tanning ledges, and multi-depth configurations create more linear feet of coping, more complex surface transitions, and longer prep times than a simple rectangular pool of the same square footage.

Access constraints matter in many Marietta neighborhoods where yards are fenced, gated, or steeply graded. Equipment staging, water haul-off, and material delivery all take longer and cost more when crews work in a tight side yard rather than an open backyard. 

These aren't reasons to avoid the project, but they are reasons why an in-person assessment produces a more accurate number than any online calculator.

Shell Condition and Surface Preparation Needs

The existing surface condition is one of the largest price variables. A pool with delaminating plaster or a shell that has been resurfaced multiple times may require acid washing, mechanical grinding, or application of a bonding agent before new material will adhere properly. 

Skipping that prep work leads to premature failure of the new surface, which is a cost multiplier that shows up two or three seasons later.

Marietta's water chemistry compounds this. The elevated calcium hardness in Cobb County water deposits scale on surfaces over time, and if that scale hasn't been managed, it creates an uneven substrate that requires more prep work before a new finish can go on cleanly.

Deferred Damage Found After Demolition

Some of the most significant cost increases happen after the pool is drained and the old surface is removed. Hidden cracks that weren't visible through standing water, plumbing penetrations that have shifted, and structural voids beneath the shell all become visible at that stage. 

A well-written estimate should include an allowance for unexpected structural findings and a clear change-order policy so you know exactly how those discoveries get priced before work begins. 

Understanding the variables that affect price leads directly to the next practical question: how do you compare estimates across contractors without getting lost in the detail?

How to Compare Estimates Without Guesswork

Two renovation bids at different prices aren't always comparing the same work. Knowing what to look for protects your budget and your renovation outcome.

What a Thorough Inspection Should Cover

A credible pool renovation estimate starts with an on-site inspection, not a phone call or square-footage formula. The inspection should document the current surface condition, identify any active cracks, assess the integrity of the tile and coping, check the equipment's age and condition, and note any signs of active water loss. 

If a contractor gives you a written estimate without draining or closely examining the pool, treat that number as preliminary.

The inspection phase is also when leak detection should occur if there are any signs of unexplained water loss. Resurfacing a pool with an undetected plumbing leak is one of the most avoidable expensive mistakes in pool renovation.

Allowance Items, Change Orders, and Exclusions

Read the exclusions section of any estimate carefully. Common exclusions in Marietta renovation bids include permit fees, sales tax on materials, haul-off of demolition debris, and structural repairs beyond a certain dollar threshold. Permit costs in Cobb County add real dollars to a project, and a bid that excludes them may look cheaper on paper but isn't in practice.

Change-order terms matter just as much. A contract that lets the contractor add charges freely after demo creates budget exposure. A well-structured bid will cap or define allowances and require your written approval before any additional scope is added.

Why In-House Workmanship Affects Value

When a contractor does all work in-house rather than subcontracting phases to separate crews, you get clearer accountability, tighter scheduling, and a single warranty covering the full project. Subcontracted renovation work can introduce schedule gaps between phases that affect cure times and surface adhesion, particularly in Atlanta's summer heat.

When to Renovate Before Problems Spread

Waiting on a pool renovation rarely saves money. In most cases, deferred maintenance turns a single-scope project into a multi-scope one.

Signs the Surface Is Beyond Simple Patching

Surface patching makes sense for isolated damage, but several signs indicate the pool has moved past that stage:

• Rough, sandpaper-like texture across large areas of the pool floor or walls
  
  
• Visible staining that doesn't respond to chemical treatment
  
  
• Plaster that is peeling, chipping, or flaking in multiple locations
  
  
• Hollow spots that sound empty when tapped with a hard object
  
  
• Cracks that have grown in length or width since you first noticed them

When multiple signs are present at once, patching one area typically reveals or accelerates deterioration in adjacent areas. At that point, full resurfacing is more cost-effective than sequential patching.

When Leaks or Cracks Change the Budget

A pool that loses more water than normal evaporation would account for changes that significantly alter the renovation calculus. In the Atlanta area, evaporation typically accounts for about a quarter inch of water loss per day during peak summer heat. Losses beyond that rate point to a structural or plumbing issue that must be addressed before resurfacing begins.

Catching a crack or plumbing failure early keeps the repair scope contained. A crack treated before it reaches a plumbing penetration is a concrete repair. The same crack left unaddressed until it compromises a return line or main drain fitting becomes an excavation and plumbing project on top of the resurfacing work. The timing of your actions directly affects the final invoice.

Frequently Asked Questions

Why Is Your Pool Renovation Estimate So Different from Your Neighbor's in Marietta?

Pool renovation costs vary based on pool size, existing surface condition, chosen finish material, and whether structural or plumbing repairs are needed. Two pools that look identical from the outside can require very different scopes once an inspector drains them and closely examines the shell.

When Does a Leaking Pool Mean You Need Pool Leak Detection and Underground Plumbing Repair Before You Renovate?

If your pool is losing water beyond normal evaporation rates, a professional pool leak-detection inspection should be conducted before any renovation work begins. Applying a new surface over an active leak allows water to continue moving through the shell or plumbing, which undermines the new finish and often voids the warranty.

What Does Concrete Pool Resurfacing Typically Cost, and What Makes the Price Go Up?

In the Marietta area, concrete pool resurfacing generally ranges from $4,600 to $12,000 or more, depending on the surface finish type and the prep work required. Factors that push the number higher include delaminated or scaled plaster requiring extensive prep, premium finish materials such as pebble aggregate, and pools with complex shapes that add linear feet of surface area.

Is It Usually Cheaper to Remodel Your Existing Pool or Start Over With a New Build?

Renovation is almost always less expensive than new construction for pools with a structurally sound shell, since you're preserving the existing gunite or concrete structure rather than excavating and building from scratch. New inground pool construction in Marietta typically starts around $35,000 and climbs significantly from there, making renovation the practical choice for most aging pools.

Which Pool Renovation Upgrades Add the Most Cost: Tile and Coping, Equipment, or Plumbing Repairs?

Underground plumbing repairs carry the highest per-item cost because they require leak detection, excavation, and pipe repair or replacement before any surface work can begin. Tile and coping replacement adds cost based on linear footage and material choice. Equipment replacement is typically the most predictable line item since pump and heater costs are straightforward to quote once the equipment age and condition are confirmed.

How Long Should You Expect a Typical Pool Renovation to Take from Demo to Refill in the Atlanta Area?

A standard resurfacing project in the Atlanta area typically takes one to two weeks from drain and demo to refill and startup, assuming no structural surprises. Projects that include crack repair, plumbing work, or tile and coping replacement add time to each phase. Scheduling in fall or winter often means faster crew availability and better cure conditions than peak-summer renovation windows.

Get an Accurate Number Before Summer Gets Here

The price ranges in this guide are a starting point, not a final quote. Every Marietta pool has its own shell condition, water chemistry history, and deferred-repair situation that affect the real number. The only way to know what your renovation actually costs is an in-person inspection by a contractor who will look at what's there, not guess from a description.

If you've noticed cracking, rough texture, unexplained water loss, or a surface that's been patched more than once, the scope of work is probably clearer than you think once someone drains the pool and takes a close look. Acting before those conditions compound keeps the project in a manageable cost range.
