Whole-home repiping replaces the supply piping throughout the house when the pipe itself, not one fitting, is what keeps failing. Instead of patching the next leak and the one after that, a repipe puts in new PEX or copper from the water’s entry to every fixture, with the drywall opened only where it has to be.
In Auburn Hills the homes that reach this point are usually full of aging polybutylene or pitting copper from the 1980s and 1990s. Here is when a repipe makes sense and how it is done.
When repiping beats fixing one more leak
One leak is a repair. The signal to repipe is a pattern: a third copper pinhole this year, polybutylene fittings weeping in more than one spot, water pressure that keeps dropping as galvanized lines rust shut, or rusty water at the taps each morning. At that point the pipe material has reached the end of its service life, and every patch is money spent on a system that will fail again elsewhere. Adding up what repeated repairs and the water damage around them cost often shows a repipe is the cheaper path, not the more expensive one.
Choosing between PEX and copper
Both are sound; they suit different homes. PEX is flexible, which means fewer fittings, fewer joints to fail, and less drywall opened because it snakes through walls where rigid pipe cannot. It resists the pinhole corrosion that takes out copper and shrugs off a freeze better. Copper is rigid and time-proven, preferred by some owners and sometimes required for exposed runs. We walk through both for your home, the water, and the layout, rather than defaulting to one. Most repipes here go back in as a PEX home-run or manifold system, which also makes future service simpler.
How a repipe goes with minimal drywall
A good repipe is planned to open as little wall as possible. We map the runs, then access the lines at strategic points, through the basement ceiling, closets, and small, neat openings where a fixture ties in, rather than stripping every wall. New lines are run, tied to each fixture, pressure-tested, and only then is the old pipe abandoned or removed. The openings are patched ready for paint. Most homes keep their water on for all but short, scheduled windows during the switchover, so the house stays livable through the job.
Repiping a condo or a multi-bath home
The home’s layout shapes the job. A two-story with three or four baths has long runs and more tie-ins, which we stage room by room. A condo or townhouse near Oakland University adds the question of shared walls and whether a line is yours or the association’s, so we confirm the boundary before opening anything, the way our condo and HOA plumbing work always does. In every case the aim is the same: new supply pipe to every fixture, the old failing material out of service, and the finishes disturbed as little as the structure allows.
Permits, inspection and what it costs
A repipe is permitted and inspected work under the 2021 Michigan Plumbing Code, with the plumbing permit from the Auburn Hills Community Development Department. The cost tracks the size of the home, the number of fixtures and baths, the pipe chosen, and how accessible the runs are, since a ranch with an open basement is lighter work than a finished two-story. We scope it fixture by fixture and give you the number before starting, including the drywall left ready for paint. Done once, it ends the leaks for the life of the new pipe.

Whole home repiping questions from Auburn Hills customers
How do I know it is time to repipe instead of repair?
When the pipe itself keeps failing, not one fitting. A third copper pinhole in a year, polybutylene weeping in more than one place, pressure dropping as galvanized rusts shut, or rusty morning water all say the material is spent. At that point each patch buys little, and a repipe usually costs less than the repairs and water damage that would follow.
Is PEX or copper better for a repipe?
Both are sound, and the right one depends on the home. PEX is flexible, so it needs fewer fittings, opens less drywall, resists pinhole corrosion and handles a freeze better, which is why most repipes here use it. Copper is rigid, long-proven and sometimes preferred for exposed runs. We go through both for your layout rather than defaulting to one.
Will repiping my house destroy the drywall?
No, a planned repipe opens as little as possible. We route new lines through the basement ceiling, closets and small neat openings at each fixture instead of stripping every wall, then patch those openings ready for paint. The goal is new pipe to every fixture with the finishes disturbed only where a line has to tie in.
Can I stay in my home during a repipe?
Usually yes. Most repipes keep the water on except for short, scheduled windows while lines are switched over, so the house stays livable. We stage the work room by room on larger homes to keep at least one bathroom and the kitchen usable, and we tell you the schedule up front so you can plan around the brief shutoffs.
