Whole-Home Repipe
PEX-A or copper repipe that eliminates leaks, low pressure, and rusty water for 50+ years.

Materials
What we install vs. what corner-cutters use.
Pipe
PEX-A with expansion fittings (Uponor/Rehau) or Type L copper.
PEX-B with crimp rings or push-to-connect fittings.
Why it matters: PEX-A is more flexible and freeze-resistant; expansion fittings can't pop off.
Routing
Attic-routed with drops to fixtures.
Re-run through the slab.
Why it matters: Attic routing means future repairs are accessible.
Testing
Pressurize to 100 PSI, hold for 24 hours.
Turn on and hope.
Why it matters: Pressure test finds every joint issue before drywall goes back.

Why us
Why homeowners pick Modern Builders for whole-home repipe.
We use PEX-A (Uponor or Rehau) with expansion fittings, not push-to-connect fittings that can pop off. Every joint is expansion-tooled and pressure-tested to 100 PSI before we close the walls. We re-route lines out of your slab wherever possible, running them through the attic instead. A slab leak on new pipe is still a slab leak — running through the attic means any future issue is 30 minutes with a saw instead of a jackhammer through your living room. We patch drywall, texture-match, and prime paint every opening. You provide the finish paint color; we spray it on.
FAQs
Answers before you ask.
PEX-A vs copper?+
PEX-A is more freeze-resistant, doesn't corrode, and installs faster. Copper is proven for 100+ years but more involved to install and vulnerable to slab leaks. We recommend PEX-A for most repipes.
Will I lose water service?+
Only during the switchover — usually 4–6 hours on one day. We coordinate so you know when.
How much drywall damage?+
Minimal — we open ceilings in the attic path and small squares at each drop. Every opening is patched, textured, and primed.
Will this fix my low water pressure?+
Almost always. Galvanized pipe corrodes internally and chokes flow. New pipe restores full flow.
