Leak Repair & Repipes in St. George, UT
From leaky faucets to grey polybutylene removal and full repipes, MBR Construction Services handles leak repair and repiping across Southern Utah.
- Leaky faucet and fixture repair
- Grey polybutylene removal and repipe
- Water line repair and replacement
Leaks range from a dripping faucet to a failing pipe system hidden behind walls or under your slab. MBR Construction Services handles everything in between, including grey polybutylene removal, PEX repiping, and whole-home repipes common in older St. George, Santa Clara, and Washington homes.
Southern Utah's hard water and temperature swings accelerate pipe wear. We diagnose the source, explain your options with transparent pricing, and restore reliable water flow whether you need a targeted repair or a complete repipe.
Polybutylene replacement is one of our strongest specialties. Many Dixie-area homes built between the late 1970s and mid-1990s still have grey polybutylene supply lines that fail without warning.
Water Leaks & Hidden Leaks
From dripping faucets to leaks you cannot see.
- Faucet, fixture, and supply line leak repair
- Hidden leak diagnosis behind walls and ceilings
- Water bill and moisture investigation
Not every leak is obvious. Unexplained high water bills, damp drywall, low pressure, or the sound of running water when fixtures are off can signal a hidden leak.
MBR inspects your system, locates the source, and explains whether a targeted repair solves the problem or whether broader pipe failure means a repipe is the better long-term investment.
Slab Leaks & Pipe Failures
When failing pipes threaten your foundation and finishes.
- Slab leak evaluation and repair options
- Pipe failure assessment in older homes
- Emergency response for active leaks
Slab leaks occur when supply lines beneath your foundation develop pinholes or bursts. Signs include warm spots on the floor, unexplained pooling, or sudden pressure loss.
Depending on pipe material, routing, and the extent of damage, options may include spot repair, rerouting, or a whole-home repipe. We walk you through each option with honest pros and cons.
Grey Polybutylene & PEX Repiping
Southern Utah's most common whole-home repipe need.
- Grey polybutylene identification and assessment
- Whole-home PEX repiping
- Polybutylene vs. PEX material guidance
Grey polybutylene was installed in many homes built between the late 1970s and mid-1990s. Chlorine and minerals in Southern Utah water make the material brittle over time, leading to pinhole leaks and fitting failures.
A single polybutylene leak can be patched, but if the material runs throughout your home, partial repairs often turn into repeated callbacks. A full PEX repipe replaces failing supply lines with modern, code-compliant piping for long-term reliability. See our grey polybutylene repipe guide on the MBR blog for warning signs and what to expect.
Whole-Home Repiping Process
What to expect when MBR repipes your Southern Utah home.
- On-site assessment of pipe routes and access
- Clear quote before work begins
- Typical timeline of a few days to one week
- Testing, cleanup, and finish restoration
Every repipe starts with an inspection of your existing pipe routes, access points, and the extent of polybutylene or failing material. You receive a clear quote before any work begins.
During the repipe, supply lines are replaced with PEX routed through walls, ceilings, and accessible crawl spaces. Most whole-home repipes in St. George take a few days to about a week depending on home size and layout. We test the system and clean up before finish restoration.

Frequently asked questions
What is grey polybutylene and should I repipe?
Grey polybutylene is a plastic pipe used in many homes from the late 1970s to mid-1990s. It is prone to failure in Southern Utah's water conditions. If your home has polybutylene throughout, a full repipe is often the most reliable long-term solution.
How do I know if I have a water leak?
Signs include unexplained high water bills, wet spots, low pressure, or the sound of running water when fixtures are off. Call us for an evaluation.
How do I identify polybutylene pipes in my home?
Look for gray plastic pipe at water heater connections, under sinks, or in crawl spaces. It is often stamped with "PB" markings. If unsure, MBR can inspect your system during an on-site visit.
What are signs polybutylene is failing?
Recurring pinhole leaks, low or inconsistent pressure, visible cracks in gray pipe, and a history of multiple leak repairs in the same home are common warning signs.
Polybutylene vs. PEX: which is better?
PEX is the modern replacement for polybutylene. It is flexible, corrosion-resistant, and code-approved for residential supply lines. MBR repipes with PEX for long-term reliability.
How long does a whole-home repipe take?
Most repipes take a few days to about a week depending on home size, pipe routing, and access. We provide a timeline estimate during your inspection.
Does insurance cover polybutylene repiping?
Coverage varies by policy. Some insurers cover resulting water damage but not the repipe itself. Check with your insurance provider and we can document the condition for your claim if needed.
Do I need a complete repipe or can I repair one leak?
A single leak in an otherwise sound system may be repairable. If polybutylene runs throughout your home, a full repipe is usually more cost-effective than repeated partial repairs.
