A sump pump is the difference between a dry basement and thousands of dollars in water damage. In Maryland, where groundwater sits high across large parts of Anne Arundel and Baltimore counties and heavy summer storms arrive fast, a properly sized pump with a reliable backup is not an upgrade — it is basic protection. ProStream Plumbing installs, replaces and services sump systems throughout the Baltimore area.
Why Local Homes Need Serious Sump Systems
Low-lying communities like Glen Burnie, Brooklyn Park and Curtis Bay have a naturally high water table, and much of the surrounding area sits on dense clay that sheds water toward foundations instead of absorbing it. Older basements were rarely built with modern drainage, so the sump basin becomes the entire defense.
Storm behavior matters too. A single Chesapeake-region thunderstorm can dump several inches in an hour, saturating soil faster than it can drain. The pump either keeps up or the basement floods — and a marginal pump on a fifteen-year-old float switch usually does not keep up.
What We Install
- Primary sump pumps sized to the basin, lift height and inflow rate of your specific home.
- Battery backup systems that continue pumping through power outages.
- New basin installation in basements that have never had one, including slab cutting and drainage rock.
- Check valves, quiet discharge piping, and freeze-resistant exterior terminations.
- Alarm and float switch upgrades so you know about a problem before the water reaches the floor.
- Pump replacement and service on existing systems that are cycling too often or running weak.
Sizing Is the Part Most Installs Get Wrong
Grabbing whatever horsepower is on the shelf is not sizing. The correct pump depends on how much water enters the basin during a real storm, the vertical lift to the discharge point, the length and diameter of the discharge run, and how much friction that run adds. Undersize the pump and it cannot keep pace; oversize it and it short-cycles, wearing out the motor and switch years early.
We evaluate the basin, the lift, and the discharge path before recommending equipment, and we install with serviceability in mind so future replacement is a straightforward swap rather than a demolition job.
Pair It With the Rest of the Water Plan
A sump pump manages water that has already reached the basement. For homes with chronic moisture, it works best alongside basement waterproofing or crawl space encapsulation, which reduce how much water arrives in the first place. ProStream handles all of it, so the drainage, pumping and waterproofing are designed as one system rather than three disconnected fixes.
If your pump is over seven years old, runs constantly, or has no battery backup, call (443) 949-5878 before the next big storm.
