Basement Waterproofing in Fordham Manor, Bronx

Why Do Older Buildings in Fordham Manor Get Wet Basements?

Age is the main reason. Foundation walls of stone and brick have aged joints, and the soil around them holds water after rain. Water moves through open mortar, hairline cracks and gaps where pipes enter the wall. Some of it also comes up through the slab.

Fordham Manor is inland, so tidal flooding is not the usual cause. The more common causes are heavy rain, sloped streets that push runoff toward the building, and sewer backups in a storm. We do not assume which one applies until we see the cellar.

Boiler rooms and laundry rooms on Kingsbridge Road and Valentine Avenue are common places for a first leak to show. A damp corner behind a boiler can run for months before anyone sees it. Ask your super to check after the next hard rain, and note which wall gets wet first.

Owners and supers can help the inspection by keeping a short log. Note the date, the weather and the spot where water showed up. Photos taken a day after a storm often show salt streaks and stains that dry out by the time we arrive.

Does Waterproofing Need a Permit?

Interior sealing and drains inside the building often do not involve the street. Exterior excavation, structural wall work and anything that touches the public sidewalk can need DOB or DOT permits, which we file. Confirm current rules with the city.

If digging along the building line cuts into the sidewalk, the flags have to be replaced afterward. We handle that as part of one job so the sidewalk is not left in worse shape. Owners remain responsible for the sidewalk next to the property.

If water has come with wall cracks, a structural question may exist, and an engineer may need to look. Nothing we can confirm puts a landmark district on these blocks, but check your own address.
