Most plumbing problems are not emergencies — they are the accumulating small failures that make a home frustrating and expensive to run. A toilet that runs all night, a shutoff that will not close, a faucet dripping into the hard-water stain it created. ProStream Plumbing handles general repair work across Baltimore and the surrounding counties, with the same standards we apply to underground and specialty jobs.
Repairs We Take Care Of
- Dripping faucets, worn cartridges and failing shower and tub valves.
- Running, weak-flushing or leaking toilets, including full replacements.
- Leaking supply lines, angle stops, hose bibbs and seized shutoff valves.
- Sink, tub, shower and laundry drain leaks and trap work.
- Pressure-reducing valve replacement for homes with excessive incoming pressure.
- Fixture installation and replacement throughout the home.

Old Houses Need a Different Approach
Much of Baltimore's housing stock predates modern plumbing standards. Rowhomes with original galvanized supply lines, mixed materials from decades of piecemeal repairs, and fixtures that no longer have available parts are the norm rather than the exception.
That means a repair here is rarely a parts swap. It means knowing when a corroded galvanized nipple will disintegrate the moment a wrench touches it, and planning the repair so a fifteen-minute job does not turn into an unexpected wall opening.

Fixing the Cause, Not Just the Symptom
A fixture that keeps failing is usually telling you about a system condition — pressure that is too high, sediment carried from a deteriorating water heater, or debris from a corroding supply line. We check the obvious upstream causes so the same repair does not come back in six months.
Where the real answer is bigger than a repair, we say so plainly and quote it, without pretending a patch will hold.

ProStream is owner-operated. The licensed master plumber who quotes the work is the one who performs it, which is why the standard is consistent whether the job is a shutoff valve or a sewer main replacement.
