Quick Answer A whole house repipe in Boerne, TX typically costs between $4,500 and $15,000 depending on home size, pipe material, and access. Most Hill Country homeowners need a repipe when they have aging galvanized or polybutylene pipes, repeated leaks, discolored water, or low pressure throughout the home. PEX is the most common modern replacement material for Boerne homes.
A whole house repipe is one of the largest plumbing investments a Boerne or Fair Oaks Ranch homeowner will ever make. It is also one of the most disruptive. The good news is that a properly executed repipe permanently solves recurring leak, pressure, and water quality issues for decades. Here is what to know before you pull the trigger.
What a Whole House Repipe Actually Means
A repipe replaces the supply lines that carry water from the main shutoff to every fixture in the home. In some cases, the drain lines are also replaced, but that is a separate decision. Most repipe projects in Boerne focus on supply, with PEX or copper replacing original galvanized steel, polybutylene, or aging copper.
Repipes do not usually require gutting the home. A skilled plumber can complete most of the work through small access cuts in drywall, with patching included or arranged separately.
Signs Your Boerne Home Needs a Repipe
Several warning signs point toward repipe rather than spot repair.
Repeated leaks. If you have had three or more pinhole leaks in the past two years, the entire system is failing in stages. Spot repairs only buy time.
Discolored water. Brown or rusty water from multiple fixtures usually means pipe corrosion has reached an advanced stage.
Low water pressure. Mineral buildup and corrosion narrow the inside diameter of old pipes. If pressure is low everywhere, the pipes may be the cause. Our companion post on low water pressure in Boerne homes walks through diagnostics.
Polybutylene pipes. Polybutylene was used widely from the late 1970s through the mid 1990s. It fails unpredictably and is generally a repipe candidate as soon as it is identified.
Galvanized supply lines. Galvanized steel rusts from the inside out. Most Boerne homes built before 1970 originally had galvanized supply lines, and homes that still have them are overdue for replacement.
Visible pipe damage. Green corrosion on copper, rust scales on iron, and discoloration around joints all signal the system is on borrowed time.
Pipe Material Options for a Repipe
Most modern Boerne repipes use one of three materials.
PEX. Cross linked polyethylene tubing is flexible, freeze resistant, and the most common choice for Texas homes. Installation is faster than copper and the cost is lower.
Copper. Type L copper is durable and time tested but more expensive than PEX. Some homeowners still prefer it for resale value or aesthetic reasons in exposed runs.
CPVC. Used occasionally, but less common in new repipes than PEX.

Real Cost Ranges for a Whole House Repipe in Boerne
Repipe pricing depends on several factors.
For a typical 2,000 to 3,000 square foot Boerne home, expect $4,500 to $9,000 for a PEX repipe and $7,500 to $15,000 for copper. Larger homes, multi story homes, and homes with finished basements run higher.
Factors that increase cost include slab penetrations, multi story routing, complex layouts, asbestos abatement (rare but possible in older homes), and difficult attic or crawl space access.

What the Repipe Process Looks Like
A professional repipe in Boerne typically follows this sequence.
Day 1 includes site walkthrough, water shutoff, fixture isolation, and access cuts in walls, ceilings, and floors. Day 2 includes new pipe routing, joint installation, and connection to fixtures. Day 3 includes pressure testing, fixture reactivation, leak verification, and inspection. Drywall patching and finish work follow, typically by a separate trade unless your plumber arranges it.
Most repipes in this area finish in 2 to 4 days. You should plan for limited water access during peak install days. A good plumber will minimize downtime by working in zones.
How to Choose a Plumber for Your Repipe
A repipe is too important to hand to the lowest bidder. Use the following filters.
The plumber must be Texas licensed and insured. Get a written, itemized estimate that specifies pipe material, fixture count, access plan, warranty terms, and timeline. Confirm the plumber pulls required permits. Ask for two recent local repipe references. Verify the warranty includes both labor and materials, ideally for at least 5 years.

What to Pair With a Repipe
