ann-arbor/whole-home-repiping

PEX or copper? It is the Ann Arbor repipe question we hear most, and the honest answer is that both are excellent when installed correctly. PEX resists scale and freezing better, costs less, and fishes through framing with fewer joints; copper is the traditional premium choice with a long track record. Ann Arbor & Washtenaw water chemistry factors into the recommendation, and we quote both materials with real numbers so you choose with full information. Call (833) 834-1087.

Ask for the material comparison in writing: PEX versus copper for your specific water and home, with the price difference, the expected service life under Ann Arbor & Washtenaw conditions, and the warranty terms for each. A repipe is a decades-long decision and it deserves a document, not a verbal pitch.

How whole-home repiping works

Knowing when a repipe is warranted, versus continued repair, is a judgment call we make with evidence. Pressure testing reveals system-wide weakness that individual leaks hide. Water-quality testing shows whether the water is actively attacking the pipe or the pipe is simply old. Inspection of accessible runs, at the water heater, under sinks, in the attic, shows the pipe’s general condition: widespread corrosion, prior patches, and mixed materials all argue for replacement. The financial test is straightforward: if the annualized cost of leak repairs, drywall patches, and the risk-weighted cost of a catastrophic leak approach the annualized cost of a new system, the repipe wins. We run this math openly with Ann Arbor homeowners because a repipe sold on fear is a repipe regretted, while a repipe sold on numbers is a relief.

Signs you need whole-home repiping in Ann Arbor

• Supply pipe that is decades old and never replaced.
• Visible corrosion, flaking, or green spotting on exposed pipe.
• Multiple prior leak repairs documented around the house.
• White crust on aerators and showerheads, plus a water heater that heats slowly, signals hard-water scale building through the system.
• A slow drain that returns weeks after snaking in an older home usually means cast-iron scale or an offset joint, not a simple clog.

What’s included

• Full-home repipe in PEX or copper, your choice with honest guidance
• New main shutoff valve that actually closes
• New quarter-turn valves and supply stops at every fixture
• Strategic small openings, patched to paint-ready condition
• Pressure testing of every run before walls close

Ann Arbor & Washtenaw: how local conditions affect whole-home repiping

Repiping in Ann Arbor becomes inevitable when the system tells the same story. Water pressure fading at every fixture, rust-colored water after taps sit unused, weeping joints in the basement, and a repair log of pinholes and joint failures across several years — in a historic-district home, this is galvanized pipe reaching its end everywhere at once. Each emergency repair opens plaster walls that are expensive to restore, and each patch leaves the next weak section waiting. The decision point arrives after the second or third leak: one planned repipe, executed with the walls opened once and restored once, ends the emergency cycle and gives the house plumbing matched to modern demand.

The repipe pattern in Ann Arbor spans generations of pipe. The oldest homes carry galvanized steel, failing through internal tuberculation that chokes flow and thins walls at every thread. Copper additions develop pinholes where water chemistry finds thin spots. Later remodels layered PEX or CPVC with mixed-quality transitions, and student-rental conversions added bathrooms the original supply lines were never sized to serve. Hard water argues for scale-resistant materials and fixtures; freeze-prone crawl spaces argue for routing supply through conditioned space wherever the repipe allows. A plan inventories every generation of pipe in the walls before a single opening is made — because in these houses, the visible plumbing is never the whole system.

A whole-home repipe in Ann Arbor replaces every generation of failing pipe with one coherent modern system. After assessment — pressure and flow testing, mapping current runs, fixture and demand inventory — crews install new PEX or copper with planned, minimal openings, fishing lines through walls and ceilings to spare historic plaster where possible. Each fixture gets a new shutoff, the main valve is upgraded, and supply lines are sized for household demand, including rental-level loads. Freeze-prone runs are rerouted into conditioned space as the repipe allows. The system is pressure-tested end to end, every fixture is checked for flow and temperature, and old pipe is abandoned or removed before walls close.

What affects the cost of whole-home repiping in Ann Arbor

The repipe-versus-repair math deserves a straight explanation. Track what failing pipe actually costs: each leak’s plumbing repair, each drywall patch and paint touch-up, the higher water bills, and the low-probability but high-cost event of a major leak while the house is empty. Annualize that over the years you plan to stay. Then compare it to the repipe quote annualized over the new system’s expected service life. In Ann Arbor homes with galvanized or pinholing copper, the repipe frequently wins by the third or fourth avoided emergency, and it buys something repairs cannot: the end of wondering which wall is next.

• Documented history of leak repairs and patches
• Risk-weighted cost of a catastrophic leak
• Expected service life of the new system
• Years you plan to own the home

Common questions

How disruptive is a whole-home repipe?

Most homes take a few days with water back on each evening. We cut small strategic openings, protect floors and furniture, and patch to paint-ready condition as we go.

PEX or copper, which should I choose?

Both are excellent installed correctly. PEX resists scale and freezing better and costs less; copper is the traditional premium choice. We quote both with real numbers for your Ann Arbor & Washtenaw water conditions and let you decide.

How do I know I need a repipe and not another repair?

Repeated pinhole leaks, rusty water, and system-wide pressure loss mean the pipe itself is failing. Pressure testing and inspection during our assessment give you evidence, not a sales pitch.

Will you have to tear out my walls?

No. Old pipe is usually abandoned in place and new pipe fishes through with small strategic openings. Demolition is minimal by design.

Should I flush my water heater every year in Ann Arbor?

Annual flushing is a sound habit with Ann Arbor’s mineral-rich blended supply. Draining sediment prevents the insulating crust that forces longer recovery cycles and strains elements. While flushing, check the anode rod — hard water consumes it faster, and a depleted rod leaves the tank itself to corrode. Tankless units need descaling on a similar schedule. If flushing produces heavy sediment or rust-colored water, have the tank assessed promptly.
