Basements in Niles homes

Many homes are early to mid-1900s with block, brick or stone basements.

Older masonry basements

Mortar erosion and old clay drain tile let water in along walls and the floor joint.

Creek-side groundwater

Homes near Mosquito Creek and the Mahoning River can see higher groundwater in wet seasons.

Settling porches and additions

Additions and porches built on shallower footings can settle away from the main foundation, opening gaps where water enters.

Older neighborhoods near Mosquito Creek

Parts of Niles near the creek and the river sit on lower ground where the water table rises in spring, pushing water up through floor cracks.

Block walls from the post-war boom

Many Niles houses from the 1940s and 1950s have hollow block walls that fill with water and bow under freeze-thaw pressure.

Niles homeowners ask

Is water coming up through the floor a sign of high groundwater?

Often. Interior drainage and a sump pump relieve pressure under the slab.

Can mortar joints be repaired?

Yes, by repointing with compatible mortar.

Why is there a gap between my porch and house?

The porch may be settling on its own footing. It should be assessed and sealed so water doesn't run into the foundation.

Why is water coming up through my Niles basement floor?
