COMMON CAUSES

Why leaks develop in older Baltimore homes

Aging supply and drain pipe

Possible causes: Many older homes have galvanized steel or older copper piping. Corrosion and mineral buildup wear through pipe walls and joints.

What to check: Visible rust, pinholes, weeping joints or stains under fixtures.

When to call a plumber: If several small leaks appear, or the piping looks heavily corroded.

Failed connections and seals

Possible causes: Supply lines, shower valves, tub spouts, toilet wax rings and appliance hoses all wear out and can leak slowly.

What to check: Damp cabinet bases, wet floor around the toilet or drips inside a wall near a shower.

When to call a plumber: If tightening or resealing does not stop it.

Freezing and thawing

Possible causes: Cold snaps can crack pipes in unheated basements, exterior walls and cold corners of a rowhouse.

What to check: Leaks that appear after a freeze, often when temperatures rise.

When to call a plumber: As soon as you find water after a cold snap.

BALTIMORE HOMEOWNER NOTES

Baltimore homeowner notes

Rowhouses and older neighborhoods bring a few extra considerations.

Shared walls and neighbors

A leak in an attached home can affect the house next door. If water may be reaching a neighbor, let them know promptly.

Service line responsibility

The water line between the meter and your home is generally the property owner’s responsibility, while the meter and main belong to the utility. Confirm with the city utility if you are unsure.

Basements and access

Many rowhouse pipes run through basements and party walls. Ask how the leak will be reached and whether any wall or floor opening is needed.

FAQ

Baltimore leak repair questions

Can a small leak wait?

A slow drip is not an emergency, but small leaks rarely stay small. They can damage cabinets, floors and framing and raise water bills, so it is best to address them soon.

How do I stop a leak until it is repaired?

Turn off the shutoff for the fixture, or the main water shutoff, and contain the water. Temporary wraps and putty can slow a leak, but they are not a permanent repair.

Will a leak repair require opening the wall?

Sometimes. Many leaks at visible fixtures do not, but a leak inside a wall or floor may need an access opening. Ask what is expected before the work begins.

Could my leak be in the line under the yard or street side?

Yes. The service line can leak underground. Signs include wet ground, a moving meter with everything off and reduced pressure.

Can I check availability before I call?

Yes. The ZIP checker on the service areas page shows whether your ZIP code is in the coverage list, and calling 833-505-1423 lets you confirm for your specific address.
