What our whole house repiping service includes
Every repipe is different, but the core scope is consistent. We remove old supply lines, install new copper or PEX, test the system, and reconnect every fixture.
Work order
Whole House Repiping- Full supply line replacement: We remove all old water supply lines from the main shutoff to every fixture. That includes cold and hot runs. New copper pipe or PEX tubing goes in. We do not leave dead sections of old pipe in the walls.
- New shutoff valves: Every fixture gets a new shutoff valve. Old gate valves seize up and fail when you need them most. New quarter-turn valves let you isolate a fixture without shutting down the whole house.
- Pressure testing: We pressurize the new system to 100 psi and hold it for at least an hour. Any drop means a leak. We find it and fix it before closing walls. This step is non-negotiable on our jobs.
- Fixture reconnection: Toilets, sinks, showers, tubs, and the water heater get reconnected. New supply lines and wax rings go in where needed. We test each fixture for flow and leaks before calling the job done.
- Drywall patching: We patch the openings we make. It is not a paint-grade finish, but it is solid and ready for your painter. We keep cuts small and use existing chases where possible to limit damage.
- Documentation: You get photos of the rough-in, a fixture map, and material specs. This record helps with future remodels, insurance, or a home sale. We email it to you after the job.

How our whole house repiping process works
We plan the job before we cut a single line. You get a clear schedule, daily updates, and a house left cleaner than we found it.
Tools and methods we use for repiping
Each method answers a different question. Together they leave very little to guess.
Used for copper pipe joints. We solder with lead-free solder and check every joint for a full, even bead. No cold joints on our jobs.
Cuts copper and PEX cleanly without burrs. Clean cuts mean better joints and fewer leaks. We keep spare blades on the truck.
Finds hidden moisture behind walls and under slabs before we start. It tells us if a slab leak is present and helps us plan the repipe route.
Used for transitions between materials and at tight spots where soldering is not safe. We stock both brands for reliable connections.

How whole house repiping runs in St. Paul
St. Paul is a city of old houses. The housing stock in Summit Hill, Dayton's Bluff, and Frogtown includes a lot of pre-1940 construction with galvanized steel, plaster walls, and small chases. That changes how we repipe. We plan routes through basements and attics to avoid tearing up plaster.
Summit Hill
Many Victorians with original plaster and small pipe chases. We plan cuts carefully and patch to a solid finish.
Highland Park
Mix of 1950s ramblers and newer homes. Finished basements mean we route through ceilings to avoid demolition.
Frogtown
Older duplexes and single-family homes with galvanized steel. We often repipe two units in one project.
- Summit Hill
- Highland Park
- Frogtown
- Dayton's Bluff

PhotoGalvanized steel to PEX in Como Park
Before: A 1925 bungalow had galvanized steel supply lines. Water ran brown after vacations. Pressure dropped to a trickle when the shower and sink ran together. The homeowner had patched three leaks in two years.
After: We repiped the whole house with PEX in three days. Water ran clear immediately. Pressure at the shower measured 55 psi, up from 28 psi. No leaks after 60 days. The homeowner scheduled a water softener install.
Pinhole leaks fixed in Summit Hill
Before: A 1912 Victorian had copper supply lines with four pinhole leaks in three years. The owner worried about a burst pipe while traveling.
After: We replaced all copper with new copper in four days. Pressure held at 100 psi for two hours during testing. The home passed inspection for a refinance. No leaks in the six months since.
Frozen pipe risk removed in Dayton's Bluff
Before: A 1940s home had supply lines in an exterior wall that froze twice in five years. The second freeze burst a pipe and flooded the kitchen. The owner wanted a permanent fix.
After: We repiped with PEX and rerouted the exterior wall lines through an interior chase. The system held pressure at 100 psi. The next winter, temps hit -22 F and no pipes froze. The kitchen stayed dry.
Plumbing problems a whole house repipe solves
Most repipes start with a symptom the homeowner has been living with for months or years.
Brown or rusty water from old galvanized pipes
Rust particles clog aerators, stain fixtures, and signal pipe walls thinning from the inside. A burst is coming.
Repeated pinhole leaks in copper
Each patch costs money and damages walls. The next leak is always a few feet away. Insurance may eventually balk at repeated claims.
Low water pressure when two fixtures run
Showers trickle, washing machines take forever, and you cannot run the dishwasher and shower at once. It is a sign of severe internal corrosion.
Frozen pipes in exterior walls
Minnesota winters split pipes and flood homes. A burst in an upstairs wall can cause thousands in damage before you find it.
Why St. Paul homeowners choose full repiping
A whole-house repipe is not a small job. It is the one plumbing upgrade that fixes water quality, pressure, and leak risk in a single project.
Stop chasing pinhole leaks
Old copper develops pinholes from the inside. You patch one, another shows up three feet away. Replacing the whole system removes that cycle.
Restore water pressure
Galvanized steel closes up with rust until a pencil-width pipe carries a straw-width flow. Showers trickle. Two faucets at once kills pressure.
Protect against frozen pipes
Minnesota winters hit -20 F or colder. Old pipes in exterior walls and unheated crawlspaces freeze and burst.
Raise home value
A documented repipe is a selling point. Buyers and inspectors see new supply lines and stop worrying about the plumbing.

Reviews from St. Paul repipe customers
Our 1912 house had galvanized pipes that turned the water brown every time we came back from vacation. We got three bids for whole house repiping St. Paul MN. This crew was the only one that mapped every fixture and showed us where the lines would run. Three days later, water ran clear and pressure was better than we ever had. They patched the plaster cleanly.
We had four pinhole leaks in two years. Patching was costing us a fortune. They repiped the whole house with PEX in four days. The crew covered our floors, worked clean, and tested every joint before closing walls. Worth every penny.
Our 1920s bungalow had a mix of copper and old steel. They explained why a partial repipe would just move the problem. We went with copper repiping St. Paul and they handled the whole job. They found a frozen pipe risk in the back wall and rerouted it. That alone saved us a winter emergency.
Frequently Asked Questions

Still have a question?
Describe what you are seeing and we will point you to the right next step.
+16513720726Most St. A 1,200-square-foot home with one bathroom sits near the low end. A 2,800-square-foot home with three baths and a finished basement lands higher. Copper costs more than PEX. Access matters too: crawlspaces and plaster walls add labor. We give you a written range after the walkthrough.
A typical St. Paul repipe takes two to four working days. Day one is demo and rough-in. Day two is pressure testing and fixture hookup. Larger homes or those with plaster walls may run five days. You will have water back each evening except the first night, when the system is drained. We tell you the schedule before we start.
If your home was built before 1960 and still has galvanized steel, yes. Those pipes rust from the inside and restrict flow. If you have copper with repeated pinhole leaks, repiping is cheaper than patching every year. If your water is brown after a vacation or pressure drops when two fixtures run, call us for an inspection. We will tell you honestly whether you need a full repipe or a partial fix.
Both work. Copper lasts 50-plus years, handles heat well, and is rigid. PEX is flexible, resists freezing better, and costs less to install. In St. Paul's cold climate, PEX has an edge in exterior walls because it expands instead of splitting. Copper is often preferred for exposed runs in unfinished basements. We install both and will recommend based on your layout, budget, and how long you plan to stay.
