Marietta, Georgia, with its historic charm around the Square, family-friendly neighborhoods, and proximity to Atlanta, is a great place to call home. But like many Metro Atlanta suburbs in Cobb County, older homes here often face hidden plumbing issues due to aging copper pipes, water chemistry, and high usage. Pinhole leaks, corroded lines, and failing water heaters are among the most common problems residents encounter—issues that can lead to water damage, high bills, and stress if not addressed early.
As a family-owned plumbing company serving Marietta and surrounding areas in Cobb County, Greenlee Plumbing has helped hundreds of local homeowners with these exact concerns. We specialize in pinhole leak detection and repair, whole-house repiping (using durable PEX systems), and water heater replacement/installation. Here’s what Marietta residents need to know—and how to protect your home.
Why Pinhole Leaks Are a Growing Issue in Marietta Homes
Pinhole leaks—tiny perforations in copper pipes caused by internal corrosion—are surprisingly common in the Greater Atlanta area, including Marietta. These leaks often start small and hidden inside walls or under slabs, but they signal widespread pipe deterioration rather than an isolated problem.
Common causes in our area include:
- Water chemistry factors (e.g., mineral content or acidity accelerating pitting corrosion).
- High water pressure stressing older copper lines.
- Age of homes (many built in the 1970s–1990s with copper plumbing reaching 30–50+ years).
- Studies in nearby Cobb County (via the Cobb County-Marietta Water Authority) have investigated similar pitting, finding factors like low chlorine residuals or installation issues contributing in some cases.
Early signs? Unexplained wet spots, higher water bills, low pressure, or discolored water. Ignoring them can lead to burst pipes, mold, and costly damage.
Prevention and fixes:
- Regular professional inspections with tools like smoke machines or electronic leak detection.
- Installing pressure-reducing valves if pressure is too high.
- In severe cases, targeted repairs aren’t enough—many homeowners opt for full repiping to eliminate future risks.

When a Whole-House Repipe Makes Sense for Marietta Properties
If your home has recurring leaks, low pressure, or outdated materials (copper, galvanized, or polybutylene), a whole-house repipe replaces the entire system with modern, flexible PEX piping. This is especially relevant in Marietta, where many homes from the mid-20th century onward face copper corrosion.
Key benefits:
- Eliminates pinhole leaks and prevents future corrosion.
- Improves water pressure and flow throughout the house.
- Enhances water quality (fewer rust or sediment issues).
- Boosts home value and energy efficiency.
- Provides long-term peace of mind—often with warranties.
At Greenlee Plumbing, we use high-quality PEX A and PEX B lines, which are more affordable, require fewer fittings, and resist freezing better in Georgia winters. We complete most repipes in 1–3 days with minimal disruption, including cleanup.
Costs vary by home size and fixtures (typically $4,000–$15,000 regionally, per industry data), but it’s often more economical than repeated patch repairs. We offer transparent upfront pricing, financing, and a 20-year warranty on labor and materials for repipe jobs.

Water Heater Options: Replacement and Upgrades for Marietta Homes
Water heaters typically last 8–12 years, but hard water, sediment buildup, and high demand in family homes can shorten that. In Marietta, where residents enjoy Southern living with frequent hot showers and laundry, a reliable system is essential.
Common signs it’s time for replacement:
- Rusty water or strange noises.
- Inconsistent hot water or higher energy bills.
- Age over 10 years or visible leaks.
Popular types in 2026:
- Tank-style (gas or electric): Reliable and cost-effective for standard needs.
- Tankless/on-demand: Endless hot water, energy savings (great for larger households), and compact design.
- High-efficiency models from brands like Rheem or Rinnai often top recommendations for efficiency.
Professional installation ensures safety (proper venting, connections) and maximizes lifespan. We handle everything from standard replacements to tankless upgrades, including expansion tanks to protect against pressure issues.
