Yes, We Repipe Whole Houses. No, We Don’t Have to Gut Yours to Do It.

A repipe isn’t a repair — it’s a full replacement of the pressurized supply system, done because the pipe material itself has failed everywhere at once, not in one spot. In the Oklahoma City metro that usually means one of three things: the gray polybutylene run in houses plumbed between 1978 and 1995, galvanized steel rusted nearly shut from the inside, or thin-wall Type M copper pitted through by hard water. Each of those failures gets its own breakdown on our whole-house repiping page. What matters here is the other half of the question — not whether your pipe needs replacing, but what replacing it actually does to the house you live in.

The old pipe never comes out. It can’t. The lines inside your walls are strapped to the studs to meet code, and on a slab foundation the originals are cast into concrete under your feet. Pulling them out like a string isn’t a thing that exists. So the failed pipe is abandoned where it lies, and a completely new path is built around it — which is exactly why a repipe doesn’t require excavating your home.

The new lines go overhead, not through your slab. The new system runs through the attic and drops down inside the wall cavities to each fixture. That routing is the whole reason a repipe stays clean: the long horizontal runs never enter a finished wall, so the only openings we make are where a pipe turns down to a fixture or a valve. Bypassing the slab means no one takes a jackhammer to your floor to chase a supply line.

PEX-A, joined with fittings that tighten as they set. We run PEX-A and join it with cold-expansion fittings: the tube is stretched with a tool, a solid brass fitting is slipped inside, and the pipe’s shape memory shrinks back down and grips it — a joint that keeps closing on itself as the material recovers. That method is a defined ASTM consensus standard (F1960), rated for pressurized hot and cold water up to 180°F, not a proprietary gimmick. It’s the opposite of an insert fitting, which seats a ribbed body down inside the tube and narrows the opening at every joint — the reason we run expansion is laid out on our whole-house repiping page’s PEX-A versus PEX-B section.

Strapped to code, not draped over the joists. New pipe has to be supported at set intervals — 32 inches apart on horizontal runs and every 10 feet on vertical drops for the sizes in a house. The corner a speed-crew cuts is skipping the straps entirely, draping hundreds of feet of pipe straight across the attic trusses to save a few dollars in clamps and hours of overhead drilling. Unsupported pipe sags, rubs, and works its fittings loose over the years. Hangers aren’t optional trim; they’re what keeps the system where it was installed.

Built to take the attic and the winter. An Oklahoma attic in July pushes past 130 degrees, and PEX is pressure-rated for water across a temperature range — the hotter the water, the lower the allowable pressure — which is what lets it live up there for decades. On the cold end, the pipe’s maker states it can stretch up to three times its diameter before it bursts and rates it past 400 freeze-thaw cycles. That’s the behavior you want in a state that can drop below 20 degrees for days at a stretch.

It ends with a pressure test, not a handshake. The plumbing code doesn’t let the job finish on someone’s word. Once the system is complete, it has to be proved tight at the working pressure of the house and held for at least 15 minutes before it’s accepted — and that test happens while the walls are still open, so a weak joint shows up before anything gets closed over it. A crew that closes your walls before it pressure-tests has skipped the one step that catches a mistake while it’s still cheap to fix.

A repipe is the right answer only when the material has failed as a system. Polybutylene that has burst more than once has failed everywhere the water touches it — the water chemistry that embrittled it the first time is still in the pipes — and replacing it is the honest move. Galvanized steel rusted shut and Type M copper pitted through by hard water land in the same place: the failure is the whole run, not a spot.

One copper joint that gave out is the opposite case. That’s a cut-and-splice repair, and a crew that quotes a whole-house repipe over a single pinhole is selling the big job to skip the small one. Where any given failure falls on that line is decided by what the material and a real inspection show, not by a number quoted in your driveway — the full range of pipe fixes, from one fitting to the whole house, lives on our pipe repair and replacement page.

If someone told you your house has to come apart to be replumbed, get a second read before you sign anything. We’ll walk the house, tell you plainly whether the material has actually failed as a system or whether you’re looking at a spot repair, and show you where the pipe routes overhead so you can see for yourself how little wall has to open.

That’s the standard on a repipe too, walls and all. Call or text us — 405-519-1868.
