What our sink service includes
Every sink visit starts with a full inspection of the faucet, supply lines, P-trap, drain assembly, and shutoff valves. From there we repair or replace what is failing.
Work order
Sink Repair and Installation- Full sink inspection: We check the faucet, supply lines, P-trap, drain flange, and shutoff valves. A flashlight and leak detection equipment confirm where the water is coming from. You get a plain explanation of what is failing and what it takes to fix it.
- Faucet and cartridge repair: Worn Moen, Delta, and Kohler cartridges are the most common cause of a dripping sink. We pull the old cartridge, clean the valve body, and install a new one. Most faucet repairs take 30 to 60 minutes and stop the drip the same day.
- Drain and P-trap service: We clear blockages in the P-trap and branch line with a drain snake or auger, then reseal the connections. If the trap arm or drain assembly is cracked, we replace it with new PVC pipe and fittings. The drain gets tested under full flow before we finish.
- Supply line replacement: Old braided or copper supply lines weep and burst. We replace them with new lines and SharkBite or compression fittings, then pressure-test the connection. This is often the cheapest fix that prevents a much bigger water damage bill.
- Sink replacement: If the basin is cracked or the mounting ring is rusted out, we set a new sink in the existing cutout. We reseal the drain, reconnect the supply lines, and test everything. Most replacements take two to four hours depending on the countertop.

Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
Clears blockages in the P-trap and branch line. We start with a hand auger for simple clogs and move to a powered drain snake for heavier grease or hair buildup.
Blasts grease, scale, and debris out of drain lines with high-pressure water. Used when a snake clears the clog but the line is still coated and draining slow.
Finds water where no fitting is visibly wet. Helps trace leaks inside walls or under the cabinet floor before we open anything up.
Push-to-connect and compression fittings for fast, reliable supply line repairs. We match the fitting to the pipe material, whether it is copper pipe, PEX tubing, or old galvanized.

How sink service runs in St. Paul
St. Paul plumbing has its own personality. Much of the housing stock dates to the 1920s through the 1950s, which means galvanized pipe, copper pipe, and decades of patchwork behind the cabinet.
Summit Hill
Large older homes with original copper pipe and deep cabinets. Sink work here often means replacing shutoff valves that have not moved in decades.
Frogtown
Mix of older single-family homes and rentals. We see a lot of DIY SharkBite splices and undersized P-traps that need correcting to code.
Highland Park
Post-war homes with smaller vanities. Bathroom sink installation here usually means finding a basin that fits a tight cutout without countertop work.

PhotoDripping kitchen faucet in Highland Park
Before: A Delta kitchen faucet had dripped for months. The cabinet floor was stained and soft near the drain, and the shutoff valves were stiff and weeping. The homeowner had already replaced the aerator with no change.
After: We replaced the cartridge and seats, installed new braided supply lines, and swapped both shutoff valves. The drip stopped, the cabinet dried out, and pressure at the tap improved. Total time was about 90 minutes.
Bathroom sink replacement in Frogtown
Before: A cracked bathroom sink was leaking into the vanity. The P-trap was undersized and the supply lines were corroded. The cutout was small, so a standard drop-in sink would not fit without modification.
After: We sourced a basin that matched the cutout, replaced the P-trap with correct PVC pipe, and installed new supply lines. The vanity stayed intact, the drain tested clean, and the leak stopped. The job took about two hours.
Slow kitchen drain in Macalester-Groveland
Before: A kitchen sink drained slowly for weeks and finally backed up. The P-trap was packed with grease and the branch line was coated. A plunger made it worse by pushing water into the second basin.
After: We pulled and cleaned the P-trap, ran a drain snake through the branch line, then flushed with hot water. The drain ran full speed and the second basin stopped backing up. The whole visit took about an hour.
Sink problems we fix in St. Paul
Most sink calls come down to a handful of failures: a dripping faucet, a slow drain, a loose basin, or water where it should…
Faucet drips day and night
A steady drip wastes water, stains the basin, and wears out the valve seat.
Water pooling under the cabinet
Moisture warps the cabinet floor, grows mold, and can rot the subfloor. By the time you see it, the leak has usually been running for weeks.
Slow or backed-up drain
Grease, hair, and scale build up in the branch line until the sink will not drain at all.
Loose or cracked sink basin
A loose sink puts stress on the supply lines and drain, and a crack will spread.
Why St. Paul homeowners call us
A sink that leaks or drains slow is more than an annoyance. It warps cabinet floors, feeds mold, and runs up your water bill.

What St. Paul customers say
Our kitchen sink started dripping into the cabinet and I could not figure out where it was coming from. The tech showed up in the window they promised, found a failed Delta cartridge and a loose drain flange, and had it fixed in about an hour. He tested everything and left the cabinet dry. Fair price and no upsell.
We needed a bathroom sink replaced in an older house with a small vanity. They measured the cutout, brought a sink that fit, and handled the supply lines and P-trap while they were in there. Two hours start to finish. The new sink drains better than the old one ever did.
Called about a slow kitchen drain and a leaky faucet. They ran a snake through the branch line, replaced the faucet cartridge, and checked the shutoff valves. Everything was tested before they left. I have used them twice now and both times the price matched the quote.
