In Cold Spring's mixed housing stock, a single repair call might involve copper sweated joints, threaded galvanized fittings, push-connect PEX transitions, or CPVC drain arms โ sometimes all in the same house. Our techs carry the materials and know the techniques for every pipe type commonly found in MN homes.

Our techs work on every pipe material found in Cold Spring, MN homes, from pre-1970s galvanized to modern PEX-A crosslinked systems. The repair method matches the pipe.
Acoustic detection is most effective on pressurized supply lines. Combined with a pressure test to confirm water loss before we start, it tells us both that there's a leak and exactly where it is.
We use thermal imaging as a complement to acoustic detection โ particularly useful for slab leaks and leaks inside insulated wall cavities where sound transmission is reduced.
Our techs are proficient in copper sweating (soldering), press-fit connections (ProPress system), CPVC solvent welding, PEX crimp and expansion fitting installation, threaded galvanized repair, and ABS/PVC drain line work. We match the repair method and material to the existing pipe system rather than forcing incompatible transitions.
Drain line repairs are water-tested by running fixtures through the repaired section and visually confirming no seepage at the repair joint and downstream.
Pipe failures have different causes depending on material type, age, water chemistry, and installation history. Here's how we address each category.
Pitting corrosion in copper is sometimes systemic rather than localized โ a single pinhole is often the first of several to appear. When the camera or pressure test finds multiple deteriorated sections, we give you an honest assessment of whether targeted repair or full copper repipe is the better long-term answer.
We replace galvanized supply lines with copper or PEX โ either as targeted section replacement at active failure points or as a full-house repipe project. We connect the new material to existing fittings using dielectric unions where code requires to prevent galvanic corrosion at copper-to-galvanized transitions.
PEX is also the material of choice for extending or reconfiguring supply runs during remodel work. Its flexibility reduces fitting count and eliminates the need for torch work inside walls.
A burst pipe from freezing or sudden pressure surge requires immediate water shutoff and precise repair. We locate the failure, determine whether it's a single failure point or multiple freeze-damaged sections, and repair with a method appropriate to the pipe material โ press-fit coupling for copper, expansion coupling for PEX-A, or a mechanical repair coupling for emergency situations.
Supply line leaks under a concrete slab are identified by acoustic detection and confirmed by thermal imaging. Once located, we evaluate three repair options: direct-access repair (jackhammering to the pipe, repairing the section, and patching the slab); rerouting the line through the wall framing above slab to bypass the failed underground run; or epoxy pipe lining for older copper systems with systemic pinhole corrosion.
When galvanized supply lines are at end of life or polybutylene pipe (recalled for chronic failure) is in the home, a full repipe with PEX or copper is the permanent solution. We run new supply lines through the structure, transition all fixture connections, pressure test the entire new system, and patch access points in walls and ceilings.
Here's how a Masters Plumbing Service pipe repair call plays out in Cold Spring, MN.
Active leak? Our dispatcher walks you through shutting off the main supply valve while we drive to you. Describing what you see โ water stain on a ceiling, drop in water pressure, wet flooring โ helps us arrive with the right detection tools loaded.
This detection step routinely saves homeowners $500โ$2,000 in unnecessary drywall removal compared to opening walls speculatively.
For slab leaks, we present repair, reroute, and lining options with pricing so you can make an informed choice before any concrete is cut.
You receive a written summary of what failed, what we installed, and the warranty terms before we leave.

My older home had a copper supply line fail inside an exterior wall. The thermal camera showed the wet zone through the drywall without any cutting. They opened a 10-inch section right at the pinhole, put in a press-fit repair coupling โ no torch in my wall โ pressure tested, and patched the drywall themselves. Two hours total.
Our galvanized supply lines finally gave out โ low pressure everywhere, rust-colored water at some fixtures. Masters Plumbing Service repiped the whole house with PEX over two days. They confirmed pressure and flow at every fixture before leaving, patched all the wall access points smooth, and cleaned up each work area. One year later, no issues at all.
Pipe burst in a rental property at 2 AM โ Masters Plumbing Service's emergency line answered immediately, talked my tenant through the main shutoff, and had a tech there in 45 minutes. Freeze crack in a PEX line in an exterior wall. Repair and insulation wrap done in under two hours. Detailed receipt for insurance documentation. Exactly what I needed as a landlord dealing with a crisis remotely.

Our techs are stocked with the copper, PEX, and CPVC materials most commonly needed in Cold Spring homes and businesses.
