Why Repiping Services Matters in Dallas
Many Dallas homes are overdue for a repipe. Homes built before 1960 commonly have galvanized steel supply lines that are now 65+ years old, well past their 40-50 year rated lifespan. Homes built in the 1970s through early 1990s may have polybutylene (Poly-B) pipes, a plastic material that becomes brittle when exposed to chlorine in treated municipal water. Both materials have predictable failure modes, and in Dallas, the combination of hard water (8-9 grains per gallon from the Trinity Aquifer) and seasonal soil movement accelerates deterioration.
A repipe replaces the supply lines throughout your home with modern copper or PEX piping. It is a planned investment, not an emergency, and it eliminates the recurring costs and water damage risk of patching failing pipes year after year.

Whole-House Repiping
A complete repipe removes all existing supply lines (hot and cold) and replaces them with new copper or PEX piping from the main shutoff valve to every fixture in the home. For a typical single-family Dallas home, this involves 150-400 feet of new piping.
The process takes 3-5 days for most homes. We work in sections to minimize water interruption, typically limiting shutoff to a few hours each day. Drywall access points are patched but not finished (your painter or handyman handles final texture and paint).
Sectional Repiping
When only part of the system has failed, sectional repiping replaces the affected lines without touching the rest. This is appropriate when corrosion or leaks are concentrated in one area of the house, such as a bathroom wing or kitchen run.
Sectional repiping costs less than a full repipe but does not eliminate risk in the remaining old pipes. We will advise honestly on whether a sectional or full approach makes more sense based on the age and condition of your system.
Material Options: Copper vs. PEX
Copper has been the standard for Dallas homes since the 1960s. It resists corrosion, lasts 50+ years, and does not leach chemicals. The drawback is cost and rigidity, which requires more fittings and labor.
PEX (cross-linked polyethylene) is flexible, freeze-resistant, and significantly less expensive to install. PEX is approved by the Texas State Board of Plumbing Examiners and meets all Dallas building codes. It is the most common choice for new construction in the DFW area.
We install both and will explain the tradeoffs for your specific situation. There is no universal “best” material; it depends on your home’s layout, budget, and water quality.

Repiping Services by Dallas Neighborhood
Oak Cliff and Winnetka Heights
Homes in Oak Cliff and the Winnetka Heights Historic District date to the early 1900s through the 1940s. Original galvanized steel and even some lead supply lines still exist in unrenovated properties. A repipe in these homes often reveals corroded pipes with internal buildup reducing the effective diameter by 50% or more.
Lakewood and East Dallas
The Lakewood area (developed 1914-1940) and surrounding East Dallas neighborhoods like Lochwood (1950s ranch-style homes) frequently have copper supply lines reaching 60-70 years of age. Dallas's hard water has been dissolving copper walls at a rate of roughly 0.5-1 mil per year, leading to pinhole leaks that are expensive to patch individually.
Midway Hills and North Dallas
Midway Hills (developed starting in 1954) and the broader North Dallas suburban build-out of the 1960s-1980s represent the largest concentration of homes now reaching repiping age. Many have a mix of copper mains and galvanized branches, a combination that creates galvanic corrosion at the connection points.

Frequently Asked Questions
How do I know if my Dallas home needs repiping?
Signs include recurring leaks (more than 2 in a year), discolored or metallic-tasting water, visible corrosion on exposed pipes, low water pressure that worsens over time, and water stains on walls or ceilings. If your home was built before 1960 (galvanized steel) or between 1978-1995 (polybutylene), a professional inspection is recommended regardless of symptoms.
How long does a whole-house repipe take?
Most single-family Dallas homes take 3-5 days. Larger homes or those with complex layouts may take up to a week. Water is turned off in sections during the work, not for the entire duration. You can typically use bathrooms and kitchen during the project with some scheduling coordination.
Is PEX safe for drinking water?
Yes. PEX is NSF/ANSI 61 certified for potable water systems and approved by the Texas State Board of Plumbing Examiners. It has been used in US residential construction since the 1980s and is now the dominant pipe material in new DFW-area homes.
Does a repipe require a permit in Dallas?
Yes. Repiping work requires a plumbing permit from the City of Dallas (minimum $100 fee) and a post-installation inspection. We handle the permit application and schedule the inspection as part of the project.
